Subjective cognitive decline (terminological and diagnostic boundaries)

This article provides an overview of modern scientific domestic and foreign publications devoted to the phenomenon of subjective cognitive decline. Subjective cognitive decline is considered by the authors of this work as a transitional syndrome, borderline between the age-related cognitive norm and phenomenologically manifested cognitive disorder. A discussion of the issues of terminological and diagnostic boundaries, the dynamics of subjective cognitive decline determines the possibility of variable prediction of the course of a neurodegenerative disease, taking into account the pathogenic mechanisms of the disease and the protective properties of the cerebral-cognitive reserve, which is prospective for future research on the issue of cognitive disorders.
