Neuroimaging has provided insight into numerous neurological disorders in children, such as epilepsy and cerebral palsy. Many clinicians and investigators believe that neuroimaging holds great promise, especially in the areas of behavioral and cognitive disorders. However, concerns about the risks of various neuroimaging modalities and the potential for misinterpretation of imaging results are mounting. Imaging evaluations also raise questions about stigmatization, allocation of resources, and confidentiality. Children are particularly vulnerable in this milieu and require special attention with regards to safety (...) guidelines and modality adaptations. This article examines pediatric neuroimaging practice through an ethics lens. Most authors in the field of neuroethics focus on the future concerns of neuroimaging. In contrast, our paper examines ethical matters surrounding current clinical applications in the pediatric population. We first provide a brief overview of the neuroimaging technologies most commonly used in a pediatric clinical context and then discuss a variety of ethical issues arising from the use of these technologies.

In order to illuminate the potential harms of MRI research, we present data obtained by examining MRI research proposal files that had been submitted for review to several Canadian Research Ethics Boards. The data reveal that REB review of the studies contained omissions, considerable variability, and sometimes confusion regarding MRI research risks and risk classification. If our findings reflect the general state of REB review of MRI research in Canada and elsewhere, there is a pressing need for REBs to be (...) educated about MRI risks in order to responsibly facilitate the disclosure of these research risks in consent forms and during the consent process. Developing a standard template consent form that discloses MRI research risks might be a way to ensure attention to and disclosure of risks. (shrink)

Current medical genetics research is dominated by a single theory that supports the Human Genome Project rationale. This thesis investigates this and several alternative hypotheses and the ethical context related to their development. Firstly, the hypotheses are discussed in detail followed by a subsection in which research evidence based on each hypothesis is cited. Secondly, these medical genetics hypotheses are situated within the contemporary medical paradigm. To conclude, the thesis examines in depth the ethical and practical implications of medical genetics (...) research. A framework of analysis of scientific responsibility is used to explore these implications. Scientific responsibility, as presented in this thesis, is a process consisting of three steps: scientific discourse; the development of the nature of scientific responsibility; and, effective criticism. Once scientific responsibility is defined, the term is applied specifically to the field of medical genetics research. (shrink)

While an accurate assessment of risk is always important, it is especially so in pediatric research. Recognizing the pivotal nature of the minimal-risk standard, we set out to determine under what circumstances pediatric magnetic resonance imaging research does or does not meet this standard. We found that while the physical and psychological risks that attend the MRI procedure do not exceed minimal risk, the sedation and contrast enhancement that are sometimes associated with MRI research do, as both exceed the level (...) of risk encountered by typical, healthy children in their everyday experiences.

Many opinions and ideas about aging exist. Biological theories have taken hold of the popular and scientific imagination as potential answers to a “cure” for aging. However, it is not clear what exactly is being cured or whether aging could be classified as a disease. Some scientists are convinced that aging will be biologically alterable and that the human lifespan will be vastly extendable. Other investigators believe that aging is an elusive target that may only be “statistically” manipulatable through a (...) better understanding of the operational principles of systems situated within complex environments. Not only is there confusion over definitions but also as to the safety of any potential intervention. Curing cell death, for example, may lead to cell cancer. The search for a cure for aging is not a clearly beneficial endeavour. This paper will first, describe contemporary ideas about aging processes and second, describe several current life extension technologies. Third, it analyses these theories and technologies, focusing on two representative and differing scientific points of view. The paper also considers the public health dilemma that arises from life extension research and examines two issues, risk/benefit ratio and informed consent, that are key to developing ethical guidelines for life extension technologies.

In this paper, we first briefly describe neuroimaging technology, our reasons for studying magnetic resonance imaging (MRI) technology, and then provide a discussion of what we have identified as priority issues for paediatric MRI research. We examine the issues of respectful involvement of children in the consent process as well as privacy and confidentiality for this group of MRI research participants. In addition, we explore the implications of unexpected findings for paediatric MRI research participants. Finally, we explore the ethical issues (...) concerning advances in functional MRI. This paper aims to provide a clear description of priority paediatric MRI research ethics issues to make some preliminary recommendations regarding next steps. (shrink)
