How do we explain the coincidence of religion and madness in which prophets, founders of religions and great saints often show symptoms of an excitability that is extreme and even pathological? This book attempts to address this phenomenological problem. Richard Saville-Smith argues that 'acute religious experiences' provides a novel category to the study of the non-rational. This book provides an epidemiological approach to a crisis, which is non-veridical and non-reductionist, recognizing a predisposition due to gene variation as a perennial (...) constant, whilst affirming that culture contextualizes experiences. Informed by contemporary psychiatric theory, which is passed through the lens of mad studies, this book proposes the 'sweet-spot' of 'acute religious experiences' which express the phenomenality of madness – but where mad is good. This interdisciplinary study provides a species-wide account of interest to all disciplines that encounter such anomalies in their subjects, from fine art to psychiatry. (shrink)

The commentators provide a wealth of additional neurobiological data that ought to be integrated in a comprehensive model. This response article, however, focuses on clarification of conceptual queries, thereby outlining the proposed theory of hallucinations more sharply, discussing its relationship with schizophrenia, and explaining why underconstrained thalamocortical activation may well be a candidate mechanism responsible for acute schizophrenic symptoms other than hallucinations.

Several independent lines of research in neurobiology seem to support the phenomenologically-grounded view of the dreaming brain/mind as a useful model for psychosis. Hallucinatory phenomena and thought disorders found in psychosis share several peculiarities with dreaming, where internally generated, vivid sensorimotor imagery along with often heightened and incongruous emotion are paired with a decrease in ego functions which ultimately leads to a severe impairment in reality testing. Contemporary conceptualizations of severe mental disorders view psychosis as one psychopathological (...) dimension that may be found across several diagnostic categories. Some experimental data have shown cognitive bizarreness to be equally elevated in dreams and in the waking cognition of acutely psychotic subjects and in patients treated with pro-dopaminergic drugs, independent of the underlying disorder. Further studies into the neurofunctional underpinnings of both conditions will help to clarify the use and validity of this model. (shrink)

There is converging evidence that high doses of hallucinogenic drugs can produce significant alterations of self-experience, described as the dissolution of the sense of self and the loss of boundaries between self and world. This article discusses the relevance of this phenomenon, known as “drug-induced ego dissolution (DIED)”, for cognitive neuroscience, psychology and philosophy of mind. Data from self-report questionnaires suggest that three neuropharmacological classes of drugs can induce ego dissolution: classical psychedelics, dissociative anesthetics and agonists of the kappa opioid (...) receptor (KOR). While these substances act on different neurotransmitter receptors, they all produce strong subjective effects that can be compared to the symptoms of acute psychosis, including ego dissolution. It has been suggested that neuroimaging of DIED can indirectly shed light on the neural correlates of the self. While this line of inquiry is promising, its results must be interpreted with caution. First, neural correlates of ego dissolution might reveal the necessary neurophysiological conditions for the maintenance of the sense of self, but it is more doubtful that this method can reveal its minimally sufficient conditions. Second, it is necessary to define the relevant notion of self at play in the phenomenon of DIED. This article suggests that DIED consists in the disruption of subpersonal processes underlying the “minimal” or “embodied” self, i.e., the basic experience of being a self rooted in multimodal integration of self-related stimuli. This hypothesis is consistent with Bayesian models of phenomenal selfhood, according to which the subjective structure of conscious experience ultimately results from the optimization of predictions in perception and action. Finally, it is argued that DIED is also of particular interest for philosophy of mind. On the one hand, it challenges theories according to which consciousness always involves self-awareness. On the other hand, it suggests that ordinary conscious experience might involve a minimal kind of self-awareness rooted in multisensory processing, which is what appears to fade away during DIED.

Aims: The experience of a compromised sense of ‘self’, termed ego-dissolution, is a key feature of the psychedelic experience and acute psychosis. This study aimed to validate the Ego-Dissolution Inventory (EDI), a new 8-item self-report scale designed to measure ego-dissolution. Additionally, we aimed to investigate the specificity of the relationship between psychedelics and ego-dissolution. Method: Sixteen items relating to altered ego-consciousness were included in an internet questionnaire; 8 relating to the experience of ego-dissolution (comprising the EDI), and 8 (...) relating to the antithetical experience of increased self-assuredness. Items were rated using a visual analogue scale. Participants answered the questionnaire for experiences with classical psychedelic drugs, cocaine or alcohol. They also answered the 7 questions from the Mystical Experiences Questionnaire (MEQ) relating to the experience of unity with one’s surroundings. Results: 691 participants completed the questionnaire, providing data for 1828 drug experiences (1043 psychedelics. 377 cocaine. 408 alcohol). Exploratory factor analysis demonstrated that the 8 EDI items loaded exclusively onto a single common factor, which was orthogonal to a second factor comprised of the items relating to increased self-assuredness (rho= -.110), demonstrating discriminant validity. The EDI correlated strongly with our measure of unitive experience (rho =.735), demonstrating convergent validity. EDI internal consistency was excellent (Cronbach’s alpha 0.93). Three analyses confirmed the specificity of ego-dissolution for experiences occasioned by psychedelic drugs. Firstly, EDI score correlated with drug-dose for psychedelic drugs (rho=.371), but not for cocaine (rho=.115) or alcohol (rho=-0.055). Secondly, the linear regression line relating the subjective intensity of the experience to EDI was significantly steeper for psychedelics (unstandardized B coefficient= 0.701) compared with cocaine (0.135) or alcohol (0.144). Finally, a binary support vector machine classifier identified experiences occasioned by psychedelic drugs vs. cocaine or alcohol with over 85% accuracy using ratings of ego-dissolution and ego-inflation alone. Conclusions: Our results demonstrate the psychometric structure, internal consistency and construct validity of the EDI. Moreover, we demonstrate the close relationship between ego-dissolution and the psychedelic experience. The EDI will facilitate the study of the neuronal correlates of ego-dissolution, which is relevant for psychedelic-assisted psychotherapy and our understanding of psychosis. (shrink)

Perhaps nothing so radically changes one’s value perspective as psychosis. In a moving article, writer Mark Lukach describes his wife Giulia’s struggle with an illness presumed to be bipolar disorder. A woman with a “concrete life plan … to become a director of marketing at a fashion company and have three kids by the time she turned 35”, Gulia’s acute psychosis resulted in her ranting “unintelligible babble about heaven, hell, angels, and the devil”. For her husband, Gulia (...) had become a different person; “the person you love is no longer there, replaced by a stranger who’s shocking and exotic”.Yet, change to value systems is ubiquitous and usually far less dramatic than that occurring in...

Both scientific evidence and folklore have suggested that madness is associated with creativity, especially in the arts. Recently, more rigorous studies have confirmed to some extent these previous observations. The current view is that it is not severe and acute insanity that is related to heightened creativity, but the personality roots and soft manifestations of both schizophrenic and bipolar psychoses. The affective and cognitive peculiarities associated with schizotypic and hypomanic personalities may be preferentially related to different kinds of creative (...) endeavours, such as the sciences and arts, respectively. The connection between personality traits and creativity is produced because they share some biological-cognitive-personality features, such as cognitive disinhibition. Additionally, it has been shown that the genetic liability for both bipolar and schizophrenic psychoses is related to creativity. A prevailing hypothesis is that creativity may be one type of 'compensatory advantage' for those carrying the genes for psychosis. (shrink)

_Covert treatment raises a number of ethical and practical issues in psychiatry. Viewpoints differ from the standpoint of psychiatrists, caregivers, ethicists, lawyers, neighbours, human rights activists and patients. There is little systematic research data on its use but it is quite certain that there is relatively widespread use. The veil of secrecy around the procedure is due to fear of professional censure. Whenever there is a veil of secrecy around anything, which is aided and abetted by vociferous opposition from some (...) sections of society, the result is one of two: 1) either the activity goes underground or 2) it is reluctantly discarded, although most of those who used it earlier knew it was needed. Covert treatment has the dubious distinction of suffering both such secrecy and disapproval. Covert treatment has a number of advantages and disadvantages in psychotic disorders. The advantages are that it helps solve practical clinical problems; prevents delays in starting treatment, which is associated with clinical risks and substantial costs; prevents risk of self-destructive behaviour and/or physical assault by patient; prevents relapse; and prevents demoralization of staff. The disadvantages are that it maybe used with malafide intent by caregivers with or without the complicity of psychiatrists; it may be used to force conformity in dissenters; and the clinician may land himself in legal tangles even with its legitimate use. In addition, it may prevent insight, encourage denial, promote unhealthy practices in the treating staff and prevent understanding of why noncompliance occurs in the first place. Some support its use in dementia and learning disorders but oppose it in schizophrenia. The main reason is that uncooperative patients of schizophrenia (and related psychoses) are considered to be those who refuse treatment but retain capacity; while in dementia and severe learning disorder, uncooperative patients are those who lack capacity. This paper disputes this contention by arguing that although uncooperative patients of schizophrenia (and related psychoses) apparently retain capacity, it is limited, in fact distorted, since they lack insight. It presents the concept of insight-unconsciousness in a patient of psychosis. Just as an unconscious patient has to be given covert medical/surgical treatment, similarly an insight-unconscious patient with one of the different psychoses (in the acute phase or otherwise) may also have to be given covert treatment till he regains at least partial insight. It helps control psychotic symptoms and assists the patient in regaining enough insight to realize he needs treatment. Another argument against covert treatment is that people with schizophrenia have the capacity to learn and therefore can learn that they are required to take medications, but if medications are given covertly it may well fuel their paranoia. However, it should be noted that the patient who has lack of insight cannot learn unless he regains that insight, and he may need covert treatment to facilitate this process. Covert treatment can fuel the paranoia, true, but it can also control the psychotic symptoms sufficiently so that regular treatment can be initiated. In a patient who refuses to accept that he is sick and when involuntary commitment is not an option to be considered, covert treatment is the only option, apart from physical restraint. Ultimately, a choice has to be made between a larger beneficence (control of symptoms and start of therapy) and a smaller malevolence (necessary therapy, but without the patient's knowledge and consent). A number of practical clinical scenarios are outlined wherein the psychiatrist should adopt covert treatment in the best interests of the patient. Ethical issues of autonomy, power, secrecy and malafide intent arise; each of these can be countered only by non-malfeasance (above all, do no harm) under the overarch of beneficence (even above that, dare to care). An advance directive with health care proxy that sanctions covert treatment is presented. Questions raised by the practical clinical scenarios are then answered. The conclusions are as follows: covert treatment, i.e, temporary treatment without knowledge and consent, is seldom needed or justified. But, where needed, it remains an essential weapon in the psychiatrist's armamentarium: to be used cautiously but without guilt or fear of censure. However, the psychiatrist must use it very judiciously, in the rarest of rare cases, provided: i) he is firmly convinced that it is needed for the welfare of the patient; ii) it is the only option available to tide over a crisis; iii) continuing efforts are made to try and get the patient into regular psychiatric care; iv) the psychiatrist makes it clear that its use is only as a stop-gap; v) he is always alert to the chances of malevolence inherent in such a process and keeps away from conniving or associating with anything even remotely suspicious; and vi) he takes due precautions to ensure that he does not land into legal tangles later. The need of the hour is to explore in greater detail the need and justification for covert treatment, to lay out clear and firm parameters for its legitimate use, follow it up with standard literature and, finally, to establish clinical practice guidelines by unconflicted authors. The term "covert treatment" is preferable to "surreptitious prescribing"; they should not be used synonymously, the latter term being reserved for those cases where there is malafide intent._.

The relationship between dream content and waking life experiences remains difficult to decipher. However, some neurobiological findings suggest that dreaming can, at least in part, be considered epiphenomenal to ongoing memory consolidation processes in sleep. Both abnormalities in sleep architecture and impairment in memory consolidation mechanisms are thought to be involved in the development of psychosis. The objective of this study was to assess the continuity between delusional contents and dreams in acutely psychotic patients. Ten patients with a single (...) fixed and recurring delusional content were asked to report their dreams during an acute psychotic break. Sixteen judges with four different levels of acquaintance to the specific content of the patients’ delusions were asked to group the dreams, expecting that fragments of the delusional thought would guide the task. A mathematical index was developed in order to compare correct groupings between the four groups of judges. Most judges grouped the dreams slightly above chance level and no relevant differences could be found between the four groups [F = 1.297; p = n.s.]. Scoring of dreams for specific delusional themes suggested a continuity in terms of dream and waking mentation for two contents . These findings seem to suggest that at least some delusional contents recur within patients’ dreams. Future studies will need to determine whether such continuity reflects ongoing consolidation processes that are relevant to current theories of delusion formation and stabilization. (shrink)

The ‘diagnosis’ has not been empirically validated and remains controversial (American Psychiatric Association, 2020). And while delirium is usually treated by internists and emergency medicine physicians, psychiatrists should also be concerned about the misuse of a putative medical diagnosis and join actively in discussion about it. For one thing, patients mis-diagnosed with this condition, as Byju and Friesen’s examples suggest, may actually have another psychiatric condition and, so, be people for whose safety we should advocate. Moreover, the kinds of police interventions which Byju and Friesen document as involving excited delirium also befall patients with other psychiatric problems in whom the issue of delirium does not arise.There are at least two broad ways in which psychiatrists are qualified and obligated to engage with this issue. As physicians, we should join our medical colleagues in carefully but persistently telling the scientific, medical truth. As psychiatrists, we should bring psychiatric knowledge into the discussion, for example, by explaining what can happen when people who do not, apparently, have a diagnosable mental disorder interact under stress with other people who, apparently, do.Delirium is a clinical diagnosis, made when characteristic signs and symptoms are present which should not be made ‘by exclusion’ when, as may happen, other causes are not found. There is no evidence of delirium in any of the three clinical descriptions Byju and Friesen provide. Perhaps such evidence exists which is not in their brief reports, but these three people appear to have had, either, another psychiatric condition, such as psychosis or drug intoxication, or perhaps no [End Page 353] diagnosis at all. Psychiatrists are particularly wellpositioned to make this point since patients with mental health problems are often misdiagnosed when they seek medical attention and are told, and treated as if, “it’s all (“just”!) psychological.”Excited delirium, if it exists, is fatal in 10% of cases (Gonin, Beysard, Hersin, & Carron, 2018) and, although this is lower than the rate for delirium in general, it is still high. Medical personnel must be available to evaluate and ensure the safety of patients in custody.The potential conflict between protecting the patient and protecting the public should not be overstated. Although physical trauma and excessive administration of medications, including ketamine 500 mg IV (Orhurhu, Vashicht, Claus, & Cohen, 2023) can be lethal, mechanical restraint by itself is not (Chieze et al., 2019; Gleerup et al., 2019): something else is necessary, such as asphyxiation (Evans, Wood, & Lambert, 2003). Nor is restraint necessary in many cases in which ‘de-escalation’ techniques can be equally effective (Garriga et al., 2016; Fernández-Costa, 2020). Perhaps these points are best made by law enforcement leaders—and they have been—but psychiatrists can add that safe management of potential violence can be provided for agitated people with psychiatric conditions.Although it is not clear what kind of strength ‘superhuman’ strength might be (certainly not medical), relative imperviousness to pain is clinically described.

The Psychosis of Race offers a unique and detailed account of the psychoanalytic significance of race, and the ongoing impact of racism in contemporary society. Moving beyond the well-trodden assertion that race is a social construction, and working against demands that simply call for more representational equality, The Psychosis of Race explores how the delusions, anxieties, and paranoia that frame our race relations can afford new insights into how we see, think, and understand race's pervasive appeal. With examples (...) drawn from politics and popular culture--such as Candyman, Get Out, and the music of Kendrick Lamar--critical attention is given to introducing as well as explicating on several key concepts from Lacanian psychoanalysis and the study of psychosis, including foreclosure, phallus, the Name-of-the-Father, sinthome, and the objet petit a. By elaborating a cultural mode to psychosis and its understanding, an original and critical exposition of the effects of racialization, as well as our ability to discern the very limits of our capacity to think through, or even beyond, the idea of race, is provided. The Psychosis of Race speaks to an emerging area in the study of psychoanalysis and race, and will appeal to scholars and academics across the fields of psychology, sociology, cultural studies, media studies, and the arts and humanities.

When interacting with other people, we assume that they have their reasons for what they do and believe, and experience recognizable feelings and emotions. When people act from weakness of will or are otherwise irrational, what they do can still be comprehensible to us, since we know what it is like to fall for temptation and act against one’s better judgment. Still, when someone’s experiences, feelings and way of thinking is vastly different from our own, understanding them becomes increasingly difficult. (...) Delusions and psychosis are often seen as marking the end of intelligibility. In this paper, I argue first for the importance of seeing other people as intelligible as long as this is at all possible. Second, I argue, based on both previous literature and my own lived experience, that more psychotic phenomena than previously thought can be rendered at least somewhat intelligible. Besides bizarre experiences like illusions, hallucinations and intense feelings of significance, I also explain what it is like to lose one’s bedrock, and how this loss impacts which beliefs one has reason to reject. Finally, I give an inside account of some disturbances of reason, and show that there are important similarities between certain psychotic reasoning problems and common non-pathological phenomena.

Psychotic and prodromal states are characterized by distortions of intersubjectivity, and a number of psychopathologists see in the concrete I-You frame of the clinical encounter the manifestation of such impairment. Rümke has coined the term of ‘praecox-feeling’, designated to describe a feeling of unease emanating in the interviewer that reflects the detachment of the patient and the failure of an ‘affective exchange.’ While the reliability of the praecox-feeling as a diagnostic tool has since been established, the explanation and theoretical framing (...) of the phenomena is still lacking. By drawing on enactivist approaches to social cognition, the paper will attempt to provide such an explanation. This is relevant, since such an explanation could contribute to a more precise understanding of the phenomena in question and possibly add to our knowledge regarding the link between experiential vulnerability to psychosis and disturbed I-Thou intersubjectivity.

Autistic-spectrum conditions and psychotic-spectrum conditions (mainly schizophrenia, bipolar disorder, and major depression) represent two major suites of disorders of human cognition, affect, and behavior that involve altered development and function of the social brain. We describe evidence that a large set of phenotypic traits exhibit diametrically opposite phenotypes in autistic-spectrum versus psychotic-spectrum conditions, with a focus on schizophrenia. This suite of traits is inter-correlated, in that autism involves a general pattern of constrained overgrowth, whereas schizophrenia involves undergrowth. These disorders also (...) exhibit diametric patterns for traits related to social brain development, including aspects of gaze, agency, social cognition, local versus global processing, language, and behavior. Social cognition is thus underdeveloped in autistic-spectrum conditions and hyper-developed on the psychotic spectrum.;>We propose and evaluate a novel hypothesis that may help to explain these diametric phenotypes: that the development of these two sets of conditions is mediated in part by alterations of genomic imprinting. Evidence regarding the genetic, physiological, neurological, and psychological underpinnings of psychotic-spectrum conditions supports the hypothesis that the etiologies of these conditions involve biases towards increased relative effects from imprinted genes with maternal expression, which engender a general pattern of undergrowth. By contrast, autistic-spectrum conditions appear to involve increased relative bias towards effects of paternally expressed genes, which mediate overgrowth. This hypothesis provides a simple yet comprehensive theory, grounded in evolutionary biology and genetics, for understanding the causes and phenotypes of autistic-spectrum and psychotic-spectrum conditions.

I shall draw on my experience of being an ICU patient to make some practical, ethical, and philosophical points about the care of the critically ill. The recurring theme in this paper is ICU psychosis. I suggest that discharged patients ought to be educated about it; I discuss the obstacles in the way of accurately measuring it; I argue that we must rethink autonomy in light of it; and I suggest that the self disintegrates in the face of it.

With regard to social-cognitive deficits in autism and psychosis, Crespi & Badcock's (C&B's) theory does not incorporate the developmental context of the disorders. We propose that there is significant overlap in social-cognitive impairments, but that the exact manifestation of social-cognitive deficits is highly dependent on the dynamics of cognitive development and hence different in autism as compared to psychosis.

The study of the neuroscience and genomics of mental illness are increasingly intertwined. This is mostly due to the translation of medical technologies into psychiatry and to technological convergence. This article focuses on psychosis. I argue that the convergence of neuroscience and genomics in the context of psychosis is morally problematic, and that ethics scholarship should go beyond the identification of a number of ethical, legal, and social issues. My argument is composed of two strands. First, I argue (...) that we should respond to technological convergence by developing an integrated, patient-centred approach focused on the assessment of individual vulnerabilities. Responding to technological convergence requires that we integrate insights from several areas of ethics, translate bioethical principles into the mental health context, and proactively try to anticipate future ethical concerns. Second, I argue that a nuanced understanding of the concept of vulnerability might help us to accomplish this task. I borrow Florencia Luna’s notion of ‘layers of vulnerability’ to show how potential harms or wrongs to individuals who experience psychosis can be conceptualised as stemming from different sources, or layers, of vulnerability. I argue that a layered notion of vulnerability might serve as a common ground to achieve the ethical integration needed to ensure that biomedical innovation can truly benefit, and not harm, individuals who suffer from psychosis.

Philosophical problemsconcerning both identification of psychosis and themeaning of this concept are pointed out. The logicaldependencies between `psychosis' and `understanding'and between `understanding' and the concept ofperson are demonstrated. Studying theinterdependence of these concepts in the light ofthe actual uses of `madness' shows how the use of`psychosis' implies a radical loss of (...) understanding.The status and legitimacy of `psychosis' as a psychiatric concept is then demonstrated.

The philosophy of Thomas Kuhn proposes that scientific progress involves periods of crisis and revolution in which previous paradigms are discarded and replaced. Revolutions in how mental health problems are conceptualised have had a substantial impact on the work of mental health nurses. However, despite numerous revolutions within the field of mental health, the biological paradigm has remained largely dominant within western healthcare, especially in orientating the understanding and treatment of psychosis. This paper utilises concepts drawn from the philosophy (...) of Thomas Kuhn to explore the impact of what Kuhn terms ‘anomalies’ within the dominant biological paradigm: the anomaly of the meaningful utterance, the anomaly of complex aetiology and taxonomy and the anomaly of pharmacological inefficacy in recovery. The paper argues that the biological paradigm for understanding psychosis is in crisis and explores the implications for mental health nursing. (shrink)

Research focused on the prodromal period prior to the onset of psychosis is essential for the further development of strategies for early detection, early intervention, and disease pre-emption. Such efforts necessarily require the enrollment of individuals who are at risk of psychosis but have not yet developed a psychotic illness into research and treatment protocols. This work is becoming increasingly internationalized, which warrants special consideration of cultural differences in conceptualization of mental illness and international differences in health care (...) practices and rights regarding research participation. The process of identifying and requesting informed consent from individuals at elevated risk for psychosis requires thoughtful communication about illness risk and often involves the participation of family members. Empirical studies of risk reasoning and decisional capacity in young people and individuals with psychosis suggest that most individuals who are at-risk for psychosis can adequately provide informed consent; however ongoing improvements to tools and procedures are important to ensure that this work proceeds with maximal consideration of relevant ethical issues. This review provides a discussion of these issues in the context of international research efforts. (shrink)

This study examined the cognitive mechanism underlying acute stress in creative cognition among individuals with high and low trait anxiety. Specifically, cognitive inhibition was assessed using the flanker task during acute stress. Fifty-two participants (26 high trait anxiety, 26 low trait anxiety) (mean age = 18.94 years) underwent stress induction via the Trier Social Stress Test (TSST). They all completed the Alternative Uses Test (AUT) and the Remote Associates Test (RAT) before and after the TSST. Biochemical markers (salivary (...) cortisol and salivary alpha amylase) were recorded at regular intervals. The results showed that cognitive inhibition was influenced by trait anxiety and acute stress. Compared to before experiencing acute stress, there was a lack of cognitive inhibition in low trait anxious individuals and they performed better in AUT (fluency) after acute stress, whereas high trait anxious individuals showed a decreased interference effect and reduced performance in AUT (fluency, flexibility, and originality). In the RAT, there were shorter response times and increased accuracy after acute stress in both high and low trait anxiety groups. Thus, we suggest that cognitive control, which modulates changes in acute stress, influences creative cognition. These findings provide evidence that inhibition control mediates the effect of stress on the creativity of individuals with different trait anxiety. (shrink)

_ Source: _Volume 39, Issue 2, pp 139 - 164 The aim of the present study is to explore the significance of religiousness for patients suffering from first-episode psychosis. Our study is a thematic analysis. The study illustrates how the patients understood their hallucinations as mystical experiences. Even so, many of the patients describe their religiousness to be helpful in coping with their disorder, giving meaning to life as well as a relationship to a sacred figure. However, their religiousness (...) often contained religious omnipotent delusions, and built on hallucinations, displayed an unsecure relationship to the sacred figure. From a psychiatric point of view, the misinterpretation of hallucinations as mystical experiences may reinforce their delusional system and cause an obstacle to recovery. This misinterpretation may also cause problems for patients’ religious coping. Our findings underline the importance of taking patients’ religiousness into account in psychotherapy. (shrink)

Acute aerobic exercise has been shown to improve fine motor skills and alter activation of the motor cortex. The intensity of exercise may influence M1 activation, and further impact whole-body motor skill performance. The aims of the current study were to compare a whole-body motor skill via a piano task following moderate-intensity training and high-intensity interval training, and to determine if M1 activation is linked to any such changes in performance. Nine subjects, aged 18 ± 1 years completed a (...) control, MIT, and HIIT trial followed by administration of a piano performance task. M1 activation was evaluated by measuring oxyhemoglobin and hemoglobin difference changes during post-exercise piano performance using functional near-infrared spectroscopy. The results indicate that piano performance scores were higher after the MIT trial, but not HIIT trial, compared to the control trial. A negative relationship was detected between heart rate during HIIT and post-HIIT piano scores. M1 activation was significantly increased after the HIIT trial. M1 activation was also positively associated with piano performance when exercise trials and all trials were combined. We found that acute moderate-intensity exercise led to an improvement in complex motor skill performance while higher-intensity exercise increased M1 activation. These results demonstrate that moderate-intensity exercise can prime the nervous system for the acquisition of whole-body motor skills, suggesting that similar exercise protocols may be effective in improving the outcomes of other motor tasks performed during regular routines of daily life. In addition, it appears that improvements in motor task performance may be driven by M1 activation. Our findings provide new mechanistic insight into the complex relationship between exercise intensity, M1 activation, and whole-body motor skill performance. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 9.4 (2002) 387-394 [Access article in PDF] Psychosis Good and Bad:Values-Based Practice and the Distinction Between Pathological and Nonpathological Forms of Psychotic Experience Mike C. Jackson and K. W. M. Fulford IN TWO PAPERS in this issue of Philosophy, Psychiatry, and Psychology, Marek Marzanski and Mark Bratton (2002) and Caroline Brett (2002) develop important critiques, from the perspectives respectively of Christian theology and Eastern (...) philosophy, of our 1997 analysis of the distinction between pathological and nonpathological forms of psychotic experience (Jackson and Fulford 1997).In this response, we briefly summarize the main points from our 1997 analysis; we consider, separately, the important although very different challenges to that analysis from the perspectives of our two critics; and we briefly indicate the main lines of recent developments in policy, practice, and research in mental health as they relate to this important area of human experience. The Jackson and Fulford (1997) Analysis In our 1997 paper, we presented three case studies from a larger series (Jackson 1991, 1997, 2001) selected with the express aim of bringing into focus the conceptual difficulties that arise at the borderline between psychotic illness and what we called benign spiritual experience. On the basis of these case studies we argued thatspiritual experiences, which are essentially benign, can involve explicitly psychotic phenomenology; traditional psychiatric diagnostic methods, which focus on the form and content of beliefs and experiences, are not capable of distinguishing between pathological and nonpathological forms of such psychotic experiences; [End Page 387]evaluation of such experiences (and claims about "illness" and health more generally) necessarily involves value judgments as well as judgments about matters of fact (specifically, the "facts" of traditional descriptive psychopathology); and more specifically, the distinction between pathological and nonpathological phenomena concerns the way in which they are embedded in the structure of the values and beliefs by which the actions of the subjects concerned are defined: "In the case of pathological psychotic phenomena," we argued, "there is a radical failure of action.... In the case of spiritual psychotic phenomena, action is radically enhanced" (Jackson and Fulford 1997, 55).We then proposed a cognitive problem-solving model of psychotic experiences. This model suggests that such experiences can be a normal and adaptive psychological response to existential crises, such as loss of meaning or purpose in life, coming to terms with death or bereavement, and so on (Batson and Ventis 1982; Jackson, 1991, 1997, 2001). The model is consistent with a subsequent position paper published by the British Psychological Society arguing the case for a psychological formulation of psychotic experiences and cognitive-behavioural methods in their management (2000).In the case of nonpathological psychotic experience, the psychotic elements of the experience promote a paradigm shift in the individual's underlying assumptions, which effectively resolves their impasse and allows them to move forward. This is normally a self-limiting process, in that when the individual is able to utilize their insight, it acts to resolve the stress which triggered it. In pathological psychosis, this process fails for various possible reasons, which were not explored in any depth in that paper (but see Jackson 2001 for a more detailed discussion). The Challenge From Marzanski and Bratton Marek Marzanski and Mark Bratton reexamine the questions raised by our cases from a Christian theological perspective (Marzanski and Bratton 2002). They suggest a theologically based definition of spiritual experience according to which the criteria for "genuine" experience concerns its context within the development of the individual's religious faith. In Bratton and Marzanski's account, these criteria are based on a Christian value system.They present three cases of their own, which, in contrast to the three cases in our 1997 paper, vividly illustrate how phenomena that may be valued negatively from a medical perspective (i.e., as defined by us in terms of their consequences for action), may, at one and the same time, be valued positively from a religious perspective (i.e., in terms of their consequences for the...

The positive functions of psychosis are examined. It is concluded that psychosis might have following positive and compensating functions: satisfaction of urgent needs that otherwise would remain unsatisfied; avoidance of and coping with unbearable reality, harmful influences and stress, and/or trauma; realization of urgent but otherwise unattainable goal settings; and upgrading of social-emotional and cognitive incapacities into more adequate social-emotional and cognitive awareness and functioning. The therapeutic implications of these findings are also discussed.

Delusions and hallucinations present a challenge to traditional epistemology by allowing two people’s experiences of the world to be vastly different to each other. Traditional objective realism assumes that there is a mind-independent objective world of which people gain knowledge through experience. However, each person only has direct access to his or her own subjective experience of the world, and so neither can be certain that his or her experience represents an objective world more accurately than the other’s. This essay (...) proposes an intersubjective account of psychosis, which avoids this sceptical attack on objective certainty by considering reality not at the level of an objective mindindependent world, but at the level of peoples’ shared experiences. This intersubjective hypothesis is developed further, with reference to Husserl’s concept of multiple lifeworlds, into a relativistic account. The implication on the social role of psychiatry is also explored. (shrink)

Background: Positive effects of acute exercise on cognitive performances in general inspired research that investigated the effects of acute exercise on specific cognitive subdomains. Many existing studies examined beneficial effects of acute exercise on subsequent set shifting performance in healthy adults. Set shifting, a subdomain of executive function, is the ability to switch between different cognitive sets. The results of existing studies are inconsistent. Therefore, a meta-analysis was conducted that pooled available effect sizes. Additionally, moderator analyses were (...) carried out to identify covariates that determine the magnitude of exercise-induced set shifting benefits.Methods: Medline, PsycINFO, and SPORTDiscus were searched for eligible studies. Hedges' g corrected standardized mean difference values were used for analyses. Random-effects weights were applied to pool effects. Potential moderation of the effect of acute exercise on subsequent set shifting performance by exercise intensity, type of exercise, participants' age, and type of control group were examined.Results: Twenty-two studies were included into analysis. All aggregated effect sizes ranged from small to moderate. Overall, a small significant beneficial effect was revealed. Heterogeneity of included effect sizes was moderate and significant. Moderator analyses revealed a larger average effect in older adults than for studies examining younger adults. Light exercise led to larger effects than moderate or vigorous exercise. Studies testing acute exercise against active control groups showed a noticeably smaller average effect than studies that used passive or cognitive engaging control groups. Interestingly, application of resistance or aerobic exercise led to no different average effect sizes. However, none of the tested covariates reached statistical significance.Conclusion: Acute exercise improves subsequent set shifting performance. However, effect sizes are small, making the relevance for everyday life questionable. The results indicate that older adults benefit more from acute exercise than younger adults do. Light intensity exercise seems most effective while the type of exercise does not seem to influence the magnitude of effects. Research designs with active control groups show the smallest average effect, raising concerns about placebo effects.PROSPERO registration number: CRD42019138799. (shrink)

Eyal et al have recently argued that researchers should consider conducting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) human challenge studies to hasten vaccine development. We have conducted (J. L.) and overseen (L. D.) human challenge studies and agree that they can be useful in developing anti-infective agents. We also agree that adults can autonomously choose to undergo risks with no prospect of direct benefit to themselves. However, we disagree that SARS-CoV-2 challenge studies are ethically appropriate at this time, (...) for 3 reasons: (1) current scientific knowledge of SARS-CoV-2 infection is insufficient to manage risks; (2) autonomous decision making, while necessary, does not override concerns about risk; and (3) undertaking challenge studies now would imperil confidence in the research enterprise, potentially undermining the global response to the coronavirus disease 2019 (COVID-19) pandemic.

The insight a patient shares into their own psychosis is fundamental to their condition - it goes to the heart of what we understand 'madness' to be. Can a person be expected to accept treatment for a condition that they deny they have? Can a person be held responsible for their actions if those actions are inspired by their own unique perceptions and beliefs - beliefs that no-one else shares? The topic of insight in schizophrenia and related disorders has (...) become a major focus of research in psychiatry and psychology. It has important clinical implications in terms of outcome, treatment adherence, competence, and forensic issues. In order to study 'insight' a broad perspective is required. This involves applying knowledge from the cognitive and brain sciences, as well as from philosophy and the social sciences. Insight and Psychosis comprises a series of in-depth, well-referenced, scholarly overviews from each of these perspectives with a strong empirical foundation - including in some cases the presentation of new data and meta-analysis of the published literature. These are integrated and synthesised by the editors, both acknowledged experts in the field. The scope is truly international and spans theoretical perspectives, clinical practice, and consumer views. The book will act as a source for students and researchers interested in pursuing any number of questions and controversies around lack of insight and awareness, and will guide clinical psychologists and psychiatrists who seek a broader view of the many facets of insight that might arise during their day-to-day work.

A fictitious dialogue in which an answer is given to the question: Why are the rates of psychosis and psychopathy in the United States so high?

Over the last decade or so, several researchers have considered the predictive processing framework (PPF) to be a useful perspective from which to shed some much-needed light on the mechanisms behind psychosis. Most approaches to psychosis within PPF come down to the idea of the “atypical” brain generating inaccurate hypotheses that the “typical” brain does not generate, either due to a systematic top-down processing bias or more general precision weighting breakdown. Strong at explaining common individual symptoms of (...) class='Hi'>psychosis, such approaches face some issues when we look at a more general clinical picture. In this paper, we propose an update on the current accounts of psychosis based on the realization that a neurotypical brain constantly generates non-actual, de-coupled, counterfactual hypotheses as part of healthy cognition. We suggest that what is going on in psychosis, at least in some cases, is not so much a generation of erroneous hypotheses, but rather an inability to correctly use the counterfactual ones. This updated view casts “accurate” cognition as more fragile and delicate, but also closes the gap between psychosis and typical cognition. (shrink)

Acute Myeloid Leukemia is a kind of fatal blood cancer with a high death rate caused by abnormal cells’ rapid growth in the human body. The usual method to detect AML is the manual microscopic examination of the blood sample, which is tedious and time-consuming and requires a skilled medical operator for accurate detection. In this work, we proposed an AlexNet-based classification model to detect Acute Myeloid Leukemia in microscopic blood images and compared its performance with LeNet-5-based model (...) in Precision, Recall, Accuracy, and Quadratic Loss. The experiments are conducted on a dataset of four thousand blood smear samples. The results show that AlexNet was able to identify 88.9% of images correctly with 87.4% precision and 98.58% accuracy, whereas LeNet-5 correctly identified 85.3% of images with 83.6% precision and 96.25% accuracy.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy, Psychiatry, & Psychology 11.1 (2004) 35-41 [Access article in PDF] The Rationality of Psychosis and Understanding the Deluded Matthew R. Broome Campbell's important and influential paper (Campbell 2001) has framed the debate that Bayne and Pacherie (2004) most explicitly, and Klee (2004) and Georgaca (2004) more implicitly, engage in. Campbell has offered two broad ways of thinking about explanations of delusions—the empirical and the rational. He offers (...) some criticism of the former and an endorsement of the latter. Campbell uses examples from clinical psychopathology to illustrate his argument and Bayne and Pacherie in turn employ these. Campbell discusses the eponymously named delusions of Capgras and Cotard—the former a subtype of delusional misidentification and the latter a delusion whose content is colored predominantly with nihilistic and possibly hypochondriacal themes. Campbell, Bayne and Pacherie, and Klee discuss the empirical data in relation to such delusions and as an aid to discussing the empirical model more generally. It does seem a little unfortunate that these delusions, which are less than typical, become the focus of Campbell's paper, and Bayne and Pacherie's criticism of his work. Delusions are remarkably heterogeneous; this indeed may be part of the reason why there is so much difficulty in reaching a definition as Klee discusses, and occur in a wide variety of mental and neurological illnesses. The most common delusions are those of persecution and reference (World Health Organization [WHO] 1973) and typically occur in schizophrenia. By contrast, delusional misidentification occurs most commonly in patients with dementia, delirium, and focal cognitive impairment, but can occur in other functional psychoses such as an affective or schizophrenic psychosis. The most common form of delusional misidentification is not that of either the exotic Capgras or Fregoli syndromes but delusional misidentification for place; thus, although Bayne and Pacherie's arguments against Campbell may still hold, delusional misidentification tends to occur in the context of a patient believing that they are at home or on holiday rather than in hospital and may not necessarily involve close family members or other intimate relationships. Similarly, Cotard's syndrome tends to occur in the context of a severe depressive illness with mood-congruent psychotic symptoms, typically in an elderly individual. It does not have to have the content that the deluded is dead, but can include beliefs, for example, that the world no longer exists or that their internal organs are not present. Thus, a patient with either Capgras' or Cotard's syndrome is likely to differ from patients with delusions of persecution. They would [End Page 35] have different diagnoses, probably be older, and have a greater likelihood of structural abnormalities of the brain on imaging and consequent neuropsychological dysfunction. That is not to say that patients with schizophrenia have normal cerebral anatomy and neuropsychology, but rather that the Capgras' and Cotard's patients are likely to have neurological quality to their presentation that is clinically relevant, rather than what commonly the case in schizophrenia and the other functional psychoses, where the neurological abnormalities are only currently important at the level of academic research. Empirical Models of Delusion Formation Different delusions may not have that much in common, nor may the patients who believe in them. This in turn relates to the empirical paradigm that both Campbell and Bayne and Pacherie discuss. It is true that current research, and indeed the clinical practice of cognitive behavioral therapy for psychosis, is indebted to the work of Maher and it is within his legacy which we work. This, however, is not to say that we think his initial formulation was correct. Maher's (1988, 1992) work focused attempts in explaining delusions—both to support and refute his thesis that delusions are the consequence of normal cognitive mechanisms seeking to explain an anomalous sensory experience. Such a view initially led to work demonstrating delusions in the absence of anomalous perceptions, the presence of reasoning biases in the deluded population, and the possibility that abnormal sensory experience may be consequent upon biased cognitive processes (Garety and Freeman 1999). More recent work has demonstrated the prevalence of... (shrink)

Two studies employed a dissociative detachment induction technique to examine if experiences of dissociation increased acute shame feelings. Study 1 recruited college participants, while Study 2 enlisted adults attending treatment for childhood sexual abuse. Two hypotheses were explored: (1) more shame would be reported following a dissociative detachment induction than a relaxation induction; and (2) shame would increase when detachment was induced in the relationship context of a close other than when alone. Study 1 (N = 81) effectively induced (...) detachment and participants reported higher shame in this condition compared to the relaxation condition. This effect was maintained when state anxiety was controlled. The relationship context produced no impact on dissociation or shame. Attributions around feeling flawed predominantly linked detachment experiences with subsequent shame feelings. In Study 2 with clinical participants (N = 28), regression analyses showed state shame was predicted by acute detachment after controlling for state anxiety, gender, and trait shame and dissociation. The most common appraisals offered for why detachment led to feelings of shame was being flawed and exposed. Collectively, our findings suggest that increased acute shame results from detachment experiences, making more specific the relationship between shame and dissociation. (shrink)

Research suggests that sedentary behavior is negatively associated with cognitive outcomes. Interrupting prolonged sitting has been shown to improve cognitive functions, including executive functioning, which is important for academic performance. No research has been conducted on the effect of standing on EF in VET students, who make up a large proportion of the adolescent population and who are known to sit more than other students of this age. In this study, we investigated the acute effects of reducing SB by (...) short time standing on EF in vocational education and training students. In a randomized crossover study, 165 VET students were first taught for 15 min in seated position. After this, they performed while seated the Letter Memory Test for updating, and the Color Shape Test for shifting and inhibition. Students were randomly assigned to a sitting or standing condition. All students were taught again for 15 min and then took the same tests in the condition they were allocated to, respectively, standing or seated. After 1 week, the test procedure was repeated, in which students switched conditions. Mixed model analyses showed no significant effect of sitting or standing on updating, shifting, or inhibition. Also, no significant differences were found for the order of condition on updating, shifting, or inhibition. Our results suggest that 40 min of standing does not significantly influence EF among VET students. (shrink)

ObjectiveThe study is an explorative investigation aimed to assess the differences in acute stress response patterns of health workers facing coronavirus disease 2019 (COVID-19) during Italy’s first lockdown.MethodsA cross-sectional investigation using convenience sampling method was conducted in Italy during April 2020. Eight hundred fifty-eight health workers participated in the research filling out self-report measures including Patient Health Questionnaire (PHQ-9), Generalized Anxiety Disorder (GAD-7), Insomnia Severity Index (ISI), and Impact of Event Scale–Revised (IES-R).ResultsModerate/severe depression was found in 28.9% (95% CI, (...) 25.8–32.04), moderate/severe anxiety in 55.4% (95% CI, 51.9–58.8), insomnia in 15% (95% CI, 12.5–17.5), and distress in 52.5% (95% CI, 48.5%–56.6) of participants. The 3% of health workers reported frequent suicidal thoughts. Female sex, working for >15 h/week in a COVID-19 unit, and living apart from family were associated with a significantly higher risk of distress, anxiety, insomnia, depression, and functional impairment. Four profiles were identified on the basis of psychopathological measures: Profile_0 included 44% (N= 270); Profile_1, 25.6% (N= 157); Profile_2, 19.1% (N= 117); and Profile_3, 11.3% (N= 69) of participants. Results showed a significant effect for Profiles X IES-R (η2= 0.079;f= 0.29), indicating that in all profiles, except for Profile_0, avoidance scale is lower than hyperarousal and intrusion symptoms scales of the IES-R. This characteristic could be a probable index of the control exerted by the responders to not fly away from their job.ConclusionThe identification of specific profiles could help psychiatrists and emergency psychologists to build specific interventions in terms of both primary and secondary prevention to face future waves of the COVID-19 outbreak.

Both daily demands as well as training and competition characteristics in sports can result in a psychobiological state of mental fatigue leading to feelings of tiredness, lack of energy, an increased perception of effort, and performance decrements. Moreover, optimal performance will only be achievable if the balance between recovery and stress states is re-established. Consequently, recovery strategies are needed aiming at mental aspects of recovery. The aim of the study was to examine acute effects of potential mental recovery strategies (...) on subjective-psychological and on cognitive performance outcomes after a mentally fatiguing task. A laboratory-based randomized cross-over study with twenty-four students was applied. Participants were run through a powernap intervention, a systematic breathing intervention, a systematic breathing plus mental imagery intervention, and a control condition with one trial a week over four consecutive weeks. Mental fatigue was induced by completion of the 60-min version of the AX-continuous performance test. The Short Recovery and Stress Scale and Visual Analog Scales were assessed to measure effects on perceptual outcomes. Cognitive performance was measured with a reaction time test of the Vienna Test System. During all three recovery interventions and CC portable polysomnography was applied. Results showed a significant increase from pre-AX-CPT to pre-MR on fatigue states and recovery-stress states indicating that the induction of mental fatigue was effective. Moreover, results underlined that analysis yielded no significant differences between recovery interventions and the control condition but they revealed significant time effects for VAS, SRSS items, and cognitive performance. However, it could be derived that the application of a rest break with 20 min of mental recovery strategies appears to enhance recovery on a mainly mental and emotional level and to reduce perceived mental fatigue.

This study investigated acute effects of real and imagined endurance exercise on sustained attention performance in healthy young adults in order to shed light on the action mechanisms underlying changes in cognitive functioning. The neural similarities between both imagined and physically performed movements reveal that imagery induces transient hypofrontality, whereas real exercise reflects both transient hypofrontality effects and the global release of signaling factors due to muscle contraction and the accompanying sensory feedback. We hypothesized improved cognitive functioning after both (...) interventions with greater improvements for real exercise because it targets both mechanisms. Fifty-three sport science students completed two 25-min sessions of moderate endurance exercise in either a motor imagery modality or an executed bodily activity within the framework of an order-balanced crossover study. Assessments for sustained attention performance were performed before and after each endurance exercise condition. Statistical results showed improvements for both groups over time, which can mostly be explained by retest effects. However, we observed a significant interaction effect between group and time, F = 3.64, p = 0.04, η2 = 0.07, with higher increases in the first session in case physical endurance exercise was performed compared to motor imagery exercise, t = −2.71, p = 0.09, d = 0.75. This might suggest that the release of signaling factors due to muscle contractions with sensory feedback processing is an additional mediating mechanism alongside motor-related transient hypofrontality that improves cognitive performance.

In this ground breaking and controversial work Richard Bentall shatters the myths that surround madness. He shows there is no reassuring dividing line between mental health and mental illness.
