A clinical case of Klinefelter's syndrome with various psychiatric symptoms

We present here a clinical case of Klinefelter's syndrome with various psychiatric symptoms. A 60-year-old male showed delusions of persecution, poisoning, and reference, auditory, visual and somatic hallucinations, depressive state and memory disturbance. These clinical symptoms except for memory disturbance were the characteristic clinical features of psychiatric symptoms in some cases of Klinefelter's syndrome reported so far. There has been no reported case of Klinefelter's syndrome showing memory disturbance. The memory disturbance of the present case is regarded as an amnestic organic brain syndrome (DSM-III) due to Klinefelter's syndrome.
