[Evoked potentials of the brain in early diagnostics of the cognitive disorders in the elderly patients with cardiovascular pathology].

The changes of visual, acoustic and cognitive evoked potentials of brain in 78 elderly patients were studied. Chronic ischemia of the heart and the brain with clinical signs of mild cognitive impairment was present in all patients. Distinct pathomorphologycal sings of structure disorders in brain were absent, and this fact was confirmed with the help of neuroimaging investigations. It was determined that deflections in the indexes of evoked potentials from the age according standard are objective and reliable diagnostic criterions both structural and functional changes in brain and initial cognitive deficit in the elderly patients with cardiovascular pathology. Authors offer complex examination of evoked potentials in diagnostics of the cognitive deficit and the functional separating between cortex and subcortical structures of brain.
