This episode from the radio program ‘All in the Mind’ focusses on the condition of Dissociative Identity Disorder. Reports from the Royal Commission into Child Sexual Abuse reminds us of the devastating impact that early abuse has on mental health. Dissociative identity disorder is a condition which can develop as a protective mechanism against trauma, and we hear the compelling account of a woman who, after a childhood of family abuse, lived with identities too numerous to count—and how she eventually became integrated. The episode also features Dr. Cathy Kezelman AM, President of Blue Knot Foundation and Professor Warwick Middleton who established the Trauma and Dissociation Unit, The first of its kind at Belmont Hospital in Brisbane.
