In the structure of all ischemic strokes, cardioembolic stroke (CES) takes 2nd place in prevalence after atherothrombotic. A frequent complication (CES) is cognitive impairment of varying severity. The key point of the research was to evaluate the characteristics of cognitive impairment in patients who underwent (CES) at different periods of treatment. 33 patients were examined in different periods after a stroke (acute — 10—21 days after the occurrence of CES and early recovery 40— 60 days after the occurrence of CES). In the group of men and women, patients aged from 61 to 70 years were significantly more likely to meet. The functional state of patients was evaluated by the Barthel index, on the Rankine scale. The definition of cognitive functions was carried out using the MMSE scale. The level of forming correlates with the level of restoration of cognitive functions and the level of their social adaptation. With the localization of lesions focuses in the vertebrobasilar pool, better recovery of cognitive functions is noted. Positive dynamics of cognitive impairment is noted in the early recovery period of CES in the direction of increasing scores on the MMSE scale compared with the acute period. A higher level of social adaptation determined by the Barthel index and the Rankine index contributes to a better recovery of cognitive functions of patients with CES.
