For this research, 125 patients with hypertension and type 2 diabetes have been selected to be examined by the department of vascular surgery of Lviv regional clinical hospital from 05.19.2014 to 26.12.2016 for the purpose of carotid endarterectomy (СE). The age of the patients has ranged from 40 to 71 years (on average - 56 years). Among them - 76 (60,8 %) have been men and 49 (39,2 %) women. To evaluate the features of higher cognitive functions and their dynamics after CE, some methods of experimental-psychological, including, neuropsychological survey, have been used. The results of the survey, using the method of "remembering of 10 words", have shown a decrease in the volume of short-term and long-term memory, as well as its performance at the preoperative stage. A norm is 10 words to be remembered for 1 - 3 series. During work with patients, 5 series have been required, but all 10 words have been rarely reproduced. At the third stage, a statistically significant improvement in the volume of short-term memory and its productivity (p << 0,05) has been noticed there. According to the method of "geometric figures", significant positive dynamics of the level of visual memory (p << 0,05) has been determined. Interpretation of the results of the digital correctional sample has shown a decrease of attention concentration (the prevalence of mistakes in the left half of the form) and mental working capacity (the number of treated lines for 6 minutes, not more than 31,41 +- 0,8 at the rate of 50), but no attention depletion has been detected. During the 2<^>nd survey a positive dynamic of these indicators and a statistically significant increase in attention at the 3<^>rd stage of the study (p << 0,05) have been determined. According to the results of the neuropsychological examination using a standardized set of neuropsychological methods (SNM), patients have shown deviations from normative indices in all test blocks. The most frequent defects have been auditory memory violations (tests for repetition of words not related to the content, reproduction of the narrative), dynamic praxis ("fist-rib-palm test", "play on the piano"), constructive praxis (optical-spatial disturbance in the drawing of figures with a turning of <$E180~symbol Р roman C>, spatial thinking - a sample of hands), identification and playback of rhythms (errors in the evaluation of simple and complex rhythms, extra blows), a sufficiently large score in reading unit (due to a violation of the quality of the pronunciation "noisy" letters), gross violations of softness. Relatively fewer violations have been found in the blocks of "account", "letter" and "thinking". The results of the 3<^>rd survey has shown a significant improvement in auditory memory, expressive language, writing, visual and tactile gnosis, dynamic and constructive practical activity (p << 0,05). Statistically unreliable results in such blocks as "rhythm", "account", "reading", "tactile gnosis", and "thinking". According to a survey conducted at the 3<^>rd stage of the survey, patients have noted improvement in their condition - in 74 % of cases, deterioration - at 11 %, without changes - 15 %.
