Ira Brenner investigates how severe traumatic experiences can lead to the development of dissociative disorders. The clinical pictures, diagnosis, and treatment of dissociative disorders are presented with a theoretical foundation and illustrated through case reports of the treatment of adult patients who experienced extreme cruelty as children. Against the backdrop of decades of clinical work with survivors of extreme trauma and impressively extensive theoretical research, Ira Brenner not only explores therapeutic questions but also delves into the psychological causes and consequences of the Holocaust, the Israeli-Palestinian conflict, the attacks on the World Trade Center on September 11, 2001, and the election of Donald Trump as President of the United States. This creates a bridge between clinical and applied psychoanalysis.
