PRODUCTIVE PSYCHOPATHOLOGICAL SYMPTOMS AN D CEREBRAL-CIRCULATION IN ORGANIC LESIONS OF THE BRAIN

The study was made of correlations arising between psychopathological symptoms (PPS) observed in organic brain lesions in acute posttraumati c, postoperative and posthemorrhagic periods in III patients with obje ctive data on cerebral circulation and cerebrovascular reactivity (CVR ). PPS included mental conditions of delirium type: of classical form (106 cases), of atypical forms (5 cases). In PPS there appeared a tend ency to an increase in the values of cerebral circulation and CVR. PPS patterns and regions of elevated CVR were found related. Long-term pe rsistance of PPS in the acute disease eventuated into a reduction of p sychic functions and total and regional hemodynamics. In atypical deli rium against preexisting encephalopathy the trend to hyperreactivity o f the brain vessels disappeared during a short period.
