Strange case of non-epileptic attacks of speechlessness – A single case study around an understandable misdiagnosis

In this single-case study, after a brain-damage, for a young female patient the following diagnoses were supposed in a period of nearly 20 years: depression, posttraumatic stress disorder, dissociative identity disorder, narcissism personality disorder, schizotypic personality disorder with pronounced abnormal behaviour, experiences of insufficiency with problems of segregation, psycho-neurotic symptoms with serious fluctuations of mood, motor inhibition, organic psycho-syndrome after brain contusion, emotional blockade with separation of premature parts of the self, non-epilepsy and, in contrast, complex-focal epilepsy. The article describes the history of the female patient and discusses the factors, why the correct diagnosis was misunderstood so easily for other disturbances.
