Abstract

The status of cognitive functions in 129 patients after strokewith deep hemispheric lesions was investigated. In the vastmajority of patients abnormalities (predominantly mild ormoderate) of the auditory-speech (95%) and the visual (83%)memory were observed. Mild and moderate abnormalities ofthe direct auditory-speech memory were predominant(85.6%), and delayed reproduction was mostly affected insevere disturbances. Moderate-to-severe abnormalities ofattention and moderate abnormalities of the dynamics ofmental processes prevailed in patients with right hemisphericlesions. As the result of complex therapy, memory mprovementwas observed in 65% of patients, improvement in theattention focusing in 72%, and improvement in the dynamicsof mental processes in 55% of patients.
