[Psychiatric and psychological aspects of Fahr syndrome]

The following article reports findings concerning a man who first developed symptoms in his late twenties that were later diagnosed as bilateral basal ganglia calcification. The man, now 53 years of age, shows symptoms of an alteration of his personality with despondency and nearly a total loss of drive. Earlier clinical reports assumed that the man's condition was due to a deterioration of his intelligence. The findings presented here, however, show that he had a normal IQ, and that the supposed deterioration of intelligence was only due to his loss of drive.
