[Clinico-neuropsychological studies of patients with arteriovenous malformations who have had hemorrhages with blood in the cerebral ventricles].

The clinical and neuropsychological signs were studied in 32 patients with arteriovenous malformations of various site who had sustained hemorrhages into the cerebral ventricles. The studies allowed the authors to identify the neuropsychological syndrome which involved the following signs: disorientation, chiefly in time, marked inertia in various scopes of activities, emotional and volitional disorders, and dysmnesia. Memory defects were seen in all spheres of mnestic activity: there were abnormalities in the actualization of consolidated knowledge, modal non-specific memory disorders in the experiment, defects in memory for current events. The degree of defect severity was found to be directly proportional to that of prior hemorrhages. In the absence of hydrocephalus, the disorders were regressive. The authors discuss what topical belonging of the detected syndrome is and how it is related to the phase of consciousness restoration.
