CLINICAL AND NEUROPSYCHOLOGICAL SYNDROMES OF THE DAMAGES OF HUMAN GYRUS CINGULI

There was performed clinical and neurophysiological observation of 41 patients with arteriovenous malformations (AVM) of gyrus cinguli. Diso rders of memory appeared to be the main manifestations before the oper ation in 38 patients, moreover they had the features of Korsakov's syn drome in 5 patients. Autonomic and epileptic-like fits weren't quite c haracteristic. Memory impairment was observed in 23 from 38 patients a fter operation, however there weren't found any qualitatively new diso rders. The first appearance of Korsakov's syndrome after operation was found in 3 patients. The degree of the increase of memory impairment correlated with the degree of the destruction of the gyrus cinguli as well as with the massivity of AVM passing into corpus callosum. Qualit ative analysis of amnestic syndromes revealed that practically all the patients had the alteration of the selectivity of the memory traces, inability to keep in mind the meaning of the tale. It was accompanied by an absence of criticism toward patients' own defects. Similar signs of disorders had close resemblence with amnestic defects of the patie nts with frontal damages. That testified the significance of both dama ges of frontal lobes and their connections in formation of clinical pa ttern in human.
