The related factors of subjective cognitive decline and its relationship with the progression of Alzheimer's disease / 临床神经病学杂志

ABSTRACT

Subjective cognitive decline(SCD)refers to self-perceived persistent decline in cognitive function,but the relevant neuropsychological tests remain within the normal range.It is a possible earliest preclinical stage that can be identified in the continuous progressive duration of Alzheimer's disease(AD).Many factors are involved in the occurrence of SCD and how to identify the AD progressive SCD to ultra-early intervention is the focus of current research.This paper aims to summarize and analyze the related concepts,clinical characteristics,related influencing factors,and their relationship with the progression of AD,which may provide a reference for subsequent related studies.
