[Neuropsychologic analysis of memory peculiarities in patients exposed to ionizing radiation as a result of the Chernobyl accident].

A sharp decrease in the ability to remember a number of random words was revealed in the main group in comparison with the control one. The interference tests showed significant abnormality. Word recall is much lower in main group than in the control group. Decrease in short-term and long-term visual memory was not displayed. The investigation has shown the presence of symptoms of the affected left temporal area in the form of acoustic-mnestic aphasia elements, signs of control disorder of higher nervous regulation, mnestic activity programming derangement, increase in the impediment to word traces under interference in terms of dynamic components disorders of psychic activity. The paper shows that patients exposed to ionizing radiation have memory disturbances as the result of the forebrain structures such as the cortex of left temporal and front areas with their corticosubcortical connections being damaged. It is they that play the key role in processing and reproducing verbal information.
