Personal Identity and Fractured Selves: Perspectives from Philosophy, Ethics, and Neuroscience

This book brings together some of the best minds in neurology and philosophy to discuss the concept of personal identity and the moral dimensions of treating brain disease and injury. The contributors engage a crucial question: When an individual’s personality changes radically because of disease or injury, should this changed individual be treated as the same person?

Rapid advances in brain science are expanding knowledge of human memory, emotion, and cognition and pointing the way toward new approaches for the prevention and treatment of devastating illnesses and disabilities. Through case studies of Alzheimer disease, frontotemporal dementia, deep brain stimulation, and steroid psychosis, the contributors highlight relevant ethical and social concerns that clinicians, researchers, and ethicists are likely to encounter.

Personal Identity and Fractured Selves represents the first formal collaboration between the Brain Sciences Institute and the Berman Institute of Bioethics, both at the Johns Hopkins University. The book asks neuroscientists and philosophers to address important questions on the topic of personal identity in an effort to engage both fields in fruitful conversation.
