THE ELECTROENCEPHALOGRAM IN KORSAKOFF SYNDROME
Abstract
1. The electroencephalograms were examined of 21 patients with a history of severe alcoholism and a confabulatory amnestic psychosis, nystagmus, and peripheral neuropathy.
2. The electroencephalographic findings were not characteristic of this syndrome: 17 showed abnormal tracings and there were 4 normal records. Of the abnormal records 15 contained a predominance of moderately slow activity, and 9 of these 15 showed a lesser degree of fast activity. Two individuals presented focal abnormalities that corresponded well with clinical and pneumoencephalographic evidence for cerebral trauma.
3. There was no direct correlation between the degree of the electroencephalographic abnormality and the degree and duration of the psychosis, the nystagmus, or the neuropathy.
4. The four patients who had convulsions also had cranio-cerebral injuries.
