The cost of surviving thrombotic thrombocytopenic purpura: case report.

The neuropsychiatric sequelae of thrombotic thrombocytopenic purpura (TTP) have not been discussed previously since most patients did not survive. The affective disorder, personality change, and cognitive deficits which resulted from TTP in a 55-year-old man who had already survived stage IIIB Hodgkin's disease are described. The neurologic and psychiatric residua did not indicate a chronic form of the disease.
