The efficiency of using of original stimulating programs for correction of memory decline, attention impairment and optical-spatial gnosis disorders was evaluated in 100 post stroke patients with the degree of cognitive decline from mild cognitive impairment to mild dementia in the acute period of stroke. In addition to traditional methods of treatment, we applied training using computer programs within 20-30 minutes daily 5 times a week during 14 days. Efficiency of treatment was measured by the MMSE, the FAB, the Clock drawing test, Shulte's tables and a letter correction test. After the treatment, the statistically significant improvement of cognitive functions was found in the group of patients receiving the correction with computer programs.
