Near-moderate cognitive decline

Abstract

Management of patients with cognitive impairment is one of the most relevant and important problems of neurology. It is especially important to identify cognitive impairment at the early (pre-dementia) stages, when appropriate medical measures are implemented, the progression of cognitive decline can be slowed down or stopped. Near-moderate cognitive decline (NMCD) at elderly and senile ages may be a predictor for the development of clinically significant cognitive impairment up to dementia. In most Western works, NMCD is associated with subjective cognitive decline, but it would be more legitimate to distinguish a form (a stage) of mild cognitive decline among NMCDs. It is assumed that NMCD is not necessarily a precursor to more severe cognitive impairment – the former can be a manifestation of age-related changes, emotional-affective disorders, and neurological and somatic diseases, although their presence substantially increases the risk of moderate and severe cognitive impairment. The review provides current ideas about the initial forms of cognitive decline, as well as neuroimaging data in these patients. It considers the influence of emotional-affective and cardiovascular factors on the development of cognitive deficit.
