Some people feel detached from their “self,” and the world around them seems unreal—as if their life is happening to someone else. This condition is called depersonalization. It is poorly studied and difficult to diagnose. It is known that it can be caused by a lived trauma or intense stress, but in Russia there are very few specialists who work with this disorder and know how to treat it. American psychiatrist Daphna Simeon and Australian journalist Jeffrey Abugel, who has lived with depersonalization for many years, have described in detail the disorder’s clinical signs, the history of research, theories of pathogenesis, and therapy methods. First presented to readers in Russian, the authors’ work is based on knowledge accumulated by the Mount Sinai School of Medicine and the UK’s Institute of Psychiatry at the University of Cambridge. This audiobook will be of interest to mental-health professionals and to people with depersonalization who are trying to understand what is happening to them and find a path to recovery.
