People suffering from Obsessive-Compulsive Disorder (OCD) do things they do not want to do, and/or they think things they do not want to think. In about 10 percent of OCD patients, none of the available treatment options is effective. A small group of these patients is currently being treated with deep brain stimulation (DBS). Deep brain stimulation involves the implantation of electrodes in the brain. These electrodes give a continuous electrical pulse to the brain area in which they are implanted. (...) It turns out that patients may experience profound changes as a result of DBS treatment. It is not just the symptoms that change; patients rather seem to experience a different way of being in the world. These global effects are insufficiently captured by traditional psychiatric scales, which mainly consist of behavioural measures of the severity of the symptoms. In this article we aim to capture the changes in the patients’ phenomenology and make sense of the broad range of changes they report. For that we introduce an enactive, affordance-based model that fleshes out the dynamic interactions between person and world in four aspects. The first aspect is the patients’ experience of the world. We propose to specify the patients’ world in terms of a field of affordances, with the three dimensions of broadness of scope (‘width’ of the field), temporal horizon (‘depth’), and relevance of the perceived affordances (‘height’). The second aspect is the person-side of the interaction, that is, the patients’ self-experience, notably their moods and feelings. Thirdly, we point to the different characteristics of the way in which patients relate to the world. And lastly, the existential stance refers to the stance that patients take towards the changes they experience: the second-order evaluative relation to their interactions and themselves. With our model we intend to specify the notion of being in the world in order to do justice to the phenomenological effects of DBS treatment. (shrink)

Deep Brain Stimulation (DBS) is a relatively new, experimental treatment for patients suffering from treatment-refractory Obsessive Compulsive Disorder (OCD). The effects of treatment are typically assessed with psychopathological scales that measure the amount of symptoms. However, clinical experience indicates that the effects of DBS are not limited to symptoms only: patients for instance report changes in perception, feeling stronger and more confident, and doing things unreflectively. Our aim is to get a better overview of the whole variety of changes that (...) OCD patients experience during DBS treatment. For that purpose we conducted in-depth, semi-structured interviews with 18 OCD patients. In this paper, we present the results from this qualitative study.We list the changes grouped in four domains: with regard to (a) person, (b) (social) world, (c)characteristics of person-world interactions, and (d) existential stance. We subsequently provide an interpretation of these results. In particular, we suggest that many of these changes can be seen as different expressions of the same process; namely that the experience of anxiety and tension gives way to an increased basic trust and increased reliance on one’s abilities. We then discuss the clinical implications of our findings, especially with regard to properly informing patients of what they can expect from treatment, the usefulness of including CBT in treatment, and the limitations of current measures of treatment success. We end by making several concrete suggestions for further research. (shrink)

Does DBS change a patient’s personality? This is one of the central questions in the debate on the ethics of treatment with Deep Brain Stimulation (DBS). At the moment, however, this important debate is hampered by the fact that there is relatively little data available concerning what patients actually experience following DBS treatment. There are a few qualitative studies with patients with Parkinson’s disease and Primary Dystonia and some case reports, but there has been no qualitative study yet with patients (...) suffering from psychiatric disorders. In this paper, we present the experiences of 18 patients with Obsessive-Compulsive Disorder (OCD) who are undergoing treatment with DBS. We will also discuss the inherent difficulties of how to define and assess changes in personality, in particular for patients with psychiatric disorders. We end with a discussion of the data and how these shed new light on the conceptual debate about how to define personality. (shrink)

We propose to understand social affordances in the broader context of responsiveness to a field of relevant affordances in general. This perspective clarifies our everyday ability to unreflectively switch between social and other affordances. Moreover, based on our experience with Deep Brain Stimulation for treating obsessive-compulsive disorder (OCD) patients, we suggest that psychiatric disorders may affect skilled intentionality, including responsiveness to social affordances.

In this chapter we give an overview of current and historical conceptions of the nature of obsessions and compulsions. We discuss some open questions pertaining to the primacy of the affective, volitional or affective nature of obsessive-compulsive disorder (OCD). Furthermore, we add some phenomenological suggestions of our own. In particular, we point to the patients’ need for absolute certainty and the lack of trust underlying this need. Building on insights from Wittgenstein, we argue that the kind of certainty the patients (...) strive for is unattainable in principle via the acquisition of factual knowledge. Moreover, we suggest that the patients’ attempts to attain certainty are counter-productive as their excessive conscious control in fact undermines the trust they need. (shrink)

According to the traditional Western concept of freedom, the ability to exercise free will depends on the availability of options and the possibility to consciously decide which one to choose. Since neuroscientific research increasingly shows the limits of what we in fact consciously control, it seems that our belief in free will and hence in personal autonomy is in trouble. -/- A closer look at the phenomenology of Obsessive-Compulsive Disorder (OCD) gives us reason to doubt the traditional concept of freedom (...) in terms of conscious control. Patients suffering from OCD experience themselves as unfree. The question is whether their lack of freedom is due to a lack of will power. Do they have too little conscious control over their thoughts and actions? Or could it be the opposite: are they exerting too much conscious control over their thoughts and actions? -/- In this chapter, we will argue that OCD patients testify to the general condition that exercising an increased conscious control over actions can in fact diminish the sense of agency rather than increase the experience of freedom. The experiences of these patients show that the traditional conception of freedom in terms of ‘free will’ has major shortcomings. There is an alternative, however, to be found in the work of Hannah Arendt. She advocates a conception of freedom as freedom in action. Combined with phenomenological insights on action, Arendt’s account of freedom helps us to get a more adequate understanding of the role of deliberation in the experience of freedom. We argue that the experience of freedom depends on the right balance between deliberate control and unreflective actions. (shrink)

Despite technological innovations, clinical expertise remains the cornerstone of psychiatry. A clinical expert does not only have general textbook knowledge, but is sensitive to what is demanded for the individual patient in a particular situation. A method that can do justice to the subjective and situation-specific nature of clinical expertise is ethnography. Effective deep brain stimulation (DBS) for obsessive-compulsive disorder (OCD) involves an interpretive, evaluative process of optimizing stimulation parameters, which makes it an interesting case to study clinical expertise. The (...) aim of this study is to explore the role of clinical expertise through an ethnography of the particular case of DBS optimization in OCD. In line with the topic of the special issue this article is a part of, we will also use our findings to reflect on ethnography as a method to study complex phenomena like clinical expertise. This ethnography of DBS optimization is based on 18 months of participant observation and nine in-depth interviews with a team of expert clinicians who have been treating over 80 OCD patients since 2005. By repeatedly observing particular situations for an extended period of time, we found that there are recurrent patterns in the ways clinicians interact with patients. These patterns of clinical practice shape the possibilities clinicians have for making sense of DBS-induced changes in patients’ lived experience and behavior. Collective established patterns of clinical practice are dynamic and change under the influence of individual learning experiences in particular situations, opening up new possibilities and challenges. We conclude that patterns of clinical practice and particular situations are mutually constitutive. Ethnography is ideally suited to bring this relation into view thanks to its broad temporal scope and focus on the life-world. Based on our findings, we argue that clinical expertise not only implies skillful engagement with a concrete situation but also with the patterns of clinical practice that shape what is possible in this specific situation. Given this constraining and enabling role of practices, it is important to investigate them in order to find ways to improve diagnostic and therapeutic possibilities. (shrink)

Progress in psychiatry depends on accurate definitions of disorders. As long as there are no known biologic markers available that are highly specific for a particular psychiatric disorder, clinical practice as well as scientific research is forced to appeal to clinical symptoms. Currently, the nosology of obsessive-compulsive disorder is being reconsidered in view of the publication of DSM-V. Since our diagnostic entities are often simplifications of the complicated clinical profile of patients, definitions of psychiatric disorders are imprecise and always indeterminate. (...) This urges researchers and clinicians to constantly think and rethink well-established definitions that in psychiatry are at risk of being fossilised. In this paper, we offer an alternative view to the current definition of obsessive-compulsive disorder from a phenomenological perspective.TranslationThis article is translated from Dutch, originally published in [Handbook Obsessive-compulsive disorders, Damiaan Denys, Femke de Geus (Eds.), (2007).

In their recent paper, Natalie Banner and Tim Thornton evaluate seven volumes of the Oxford University Press series “International Perspectives in Philosophy and Psychiatry,” an international book series begun in 2003 focusing on the emerging interdisciplinary field at the interface of philosophy and psychiatry. According to Natalie Banner and Tim Thornton, the series represents a clear indication that the interdisciplinary field of philosophy of psychiatry has been flourishing lately. Philosophers and psychiatrists face a “new philosophy of psychiatry”. However, the optimism (...) which the “new” philosophy of psychiatry celebrates is precisely the exiling of philosophy from the foundations of psychiatry. The 150 year old belief that psychopathology cannot do without philosophical reflection has virtually disappeared from common psychiatric education and daily clinical practice. Though the discipline of psychiatry is particularly suited to contributions from philosophy, the impact of philosophy on psychiatry nowadays remains limited. With some exceptions, philosophical papers are embedded in a philosophical context inscrutable to ordinary psychiatrists. Much current philosophical work is perceived by psychiatrists as negativistic. I would encourage the field of psychiatry to incorporate once again basic philosophical attitudes which render possible true dialogue with philosophy and enrich both disciplines. The views developed here should not discredit the value and importance of Natalie Banner and Tim Thornton’s paper and the excellent series “International Perspectives in Philosophy and Psychiatry.” As Jaspers said “Everybody inclined to disregard philosophy will be overwhelmed by philosophy in an unperceived way”.

We whole-heartedly agree with Mecacci and Haselager(2014) on the need to investigate the psychosocial effects of deep brain stimulation (DBS), and particularly to find out how to prevent adverse psychosocial effects. We also agree with the authors on the value of an embodied, embedded, enactive approach (EEC) to the self and the mind–brain problem. However, we do not think this value primarily lies in dissolving a so-called “maladaptation” of patients to their DBS device. In this comment, we challenge three central (...) claims of the authors on the basis of our direct experience with psychosocial effects of DBS in 45 obsessive- compulsive disorder (OCD) patients treated at the AMC in Amsterdam, The Netherlands, and our indepth qualitative interviews with 18 of them (de Haan et al. 2013). We end our comment by sketching out our perspective on the practical merits of an EEC approach to DBS. (shrink)

Aims and hypothesesIn an environment of absolute silence, researchers have found many of their participants to perceive phantom sounds. With this between-subject experiment, we aimed to elaborate on these research findings, and specifically investigated whether–in line with the fear-avoidance model of tinnitus perception and reactivity–fear or level of perceived threat influences the incidence and perceptual qualities of phantom sound percepts in an anechoic room. We investigated the potential role of individual differences in anxiety, negative affect, noise sensitivity and subclinical hearing (...) loss. We hypothesized that participants who experience a higher level of threat would direct their attention more to the auditory system, leading to the perception of tinnitus-like sounds, which would otherwise be subaudible, and that under conditions of increased threat, narrowing of attention would lead to perceptual distortions.MethodsIn total, N = 78 normal-hearing volunteers participated in this study. In general, the study sample consisted of young, mostly female, university students. Their hearing was evaluated using gold-standard pure tone audiometry and a speech-in-noise self-test, which is a sensitive screening test to identify subclinical hearing loss. Prior to a four-minute stay in an anechoic room, we randomized participants block design-wise in a threat and no-threat condition. Participants in the threat condition were deceived about their hearing and were led to believe that staying in the room would potentially harm their hearing temporarily. Participants were asked whether they perceived sounds during their stay in the room and rated the perceptual qualities of sound percepts. They were also asked to fill-out standardized questionnaires measuring anxiety, affect and noise sensitivity. The internal consistency of the questionnaires used was verified in our study sample and ranged between α = 0.61 and α = 0.90.ResultsIn line with incidence rates reported in the literature, 74% of our participants reported having heard tinnitus-like sounds in the anechoic room. Speech-in-noise identification ability was comparable for both groups of participants. The experimental manipulation of threat was proven to be effective, as indicated by significantly higher scores on a Threat Manipulation Checklist among participants in the threat condition as compared to those in the no-threat condition. Nevertheless, participants in the threat condition were as likely to report tinnitus percepts as participants in the no-threat condition, and tinnitus percepts were not rated as being louder or more unpleasant as a function of level of threat. For participants who did experience tinnitus percepts, a higher level of threat was associated with a higher degree of experienced unpleasantness. These associations were absent in those who did not experience tinnitus. Higher negative affect was only slightly associated with higher ratings of tinnitus unpleasantness.ConclusionWhereas our threat manipulation was successful in elevating the level of fear, it did not contribute to a higher percentage of participants perceiving tinnitus-like sounds in the threat condition. However, higher levels of perceived threat were related to a higher degree of perceived tinnitus unpleasantness. The findings of our study are drawn from a rather homogenous participant pool in terms of age, gender, and educational background, challenging conclusions that are applicable for the general population. Participants generally obtained normophoric scores on independent variables of interest: they were low anxious, low noise-sensitive, and there was little evidence for the presence of subclinical hearing loss. Possibly, there was insufficient variation in scores to find effects. (shrink)

The meeting, hosted by McGill University, was held in Montréal, from Friday, October 12, to Sunday, October 14, 1990. Approximately 125 members and friends of the Society attended. The topic of discussion was “Hegel’s Philosophy of Religion.”.

Central to Kierkegaard’s account of religious existence is his critique of speculative reason. This critique begins with the distinction between subjective and objective reflection. Its most radical aspects appear in Kierkegaard’s discussions of the paradox. In spite of Kierkegaard’s frequent comments on this notion, it is not readily understood. I want to argue against a common reading of this notion and propose an alternative reading. This alternative reading allows for a conceptually quite plausible account of the manner in which the (...) paradox presents reason with a boundary, in virtue of its relation to objective reflection and to subjective reflection as well. Because of this boundary, reason points beyond its own achievements to a domain of contemplation and appropriation. This is a domain that reason itself identifies in connection with the paradox. It both surpasses rational achievements and integrates them into itself. (shrink)
