OPTIMIZATION OF REHABILITATION PROCESS IN PATIENTS WITH CEREBRAL ISCHEMIA ACCORDING TO COGNITIVE EVOKED POTENTIALS

Objective: to study the ways of optimizing the recovery of higher cortical functions in patients with cerebral ischemia according to the data of a dynamic study of cognitive evoked potentials. Material and methods. A study of cognitive evoked potentials was carried out in patients with acute hemispheric stroke on days 1, 7, 21 from the onset of the disease. Results. The analysis of the cognitive evoked potentials revealed a significant increase in the latency of N2 to 263.8 ± 53.3 ms (p <0.05), P300 to 408.4 ± 50.1 ms (p <0.01) and a decrease in its amplitude to 3.5 ± 2.5 mV (p <0.05) in 61% (n = 39) patients with hemispheric stroke on the 1st day of the disease as compared with the same parameters in patients with encephalopathy. A statistically significant decrease in latencies and an increase in N2 and P300 amplitudes occurred in the cerebral infarction group on the 21st day of the disease as compared with the 1st day. Conclusions. In patients with hemispheric cerebral infarction cognitive components of the response suffer more than its sensory components.
