These patients consisted of four cases of epilepsy, one case of anorexia nervosa, two cases of narcolepsy and 42 cases of diencephalosis. Another series of 22 patients suffering from other diseases, in whome EEG no centrencephalic EEG abnormallities were detected, were examined with nialamide. Out of the 49 patients, 35 cases (71.4+) showed increased EEG abnormalities following the administration of nialamide. It was noteworthy that this drug had provocative effect not only for EEG abnormalities, but also for the symptoms from which patients were suffering. In 26 out of 49 patients, both EEG abnormalities and clinical symptoms were provoked by nialamide. And the nialamide administration resulted in negative on all 22 patients who did not register centrencephalic EEG abnormalities. The mechanism and characteristics of this provoca...Continue Reading
