СОВРЕМЕННОЕ СОСТОЯНИЕ ВОПРОСА РАСПРОСТРАНЕННОСТИ УМЕРЕННЫХ КОГНИТИВНыХ НАРУШЕНИЙ И ДЕМЕНЦИИ

Studying the issue of age-dependent diseases, among people 60 years and older, at the stage of the primary care, at a neurologist's appointment, the most frequent complaints of patients are: memory loss; the request to repeat several times the same information; growing dependence on written reminders and deterioration of memorization of events for the current period of time, and difficulties with solving problems or planning. All this is attributed to the first symptoms of mild cognitive impairment (MCI) and the growing risk of developing a dementia syndrome. The purpose of the paper is to elucidate the problem of the brain aging. Material and methods: we conducted a literary search in the nine electronic databases (CINAHL, MEDLINE, Embase, Cochrane Collaborative Library, Thomson Reuters Web of Science, PsycINFO, LILACS, ALOIS and Pubmed), published from December 2000 to February 2017. Conclusion: The classification of MCI improves over time, and the inclusion of images and other biomarkers can further improve the detection of subjects with MCI. This would facilitate a comparison between studies, a better selection of subjects for clinical research; provide a better understanding of the results of MCI and an earlier identification of subjects with MCI. Subjects with MCI can benefit from interventions that reduce the risk of progression of dementia and may be eligible for treatment with disease modifying drugs that prevent further decline in cognitive function and the development of dementia syndrome.
