Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to investigate the one-year trajectory of cognitive change in elderly patients with depression, to explore the transfer characteristics and transfer rules of various states of cognitive impairment in patients, to predict the relevant risk factors of cognitive decline, and to find possible influencing factors affecting state change, so as to provide a theoretical basis and reference for subsequent targeted intervention research on geriatric depression.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The 1-year prospective longitudinal study involved 400(prospective)subjects who met criteria for geriatric depression,the whole cognitive function was assessed by mini-mental state examination(MMSE),Montreal cognitive assessment scale-MOCA)and subjective cognitive decline scale(SCD-9).Cognitive function was monitored at 6 and 12 months.GAIN factors related to cognitive function(e.g.,age,gender,education,cognitive function,anxiety level,sleep,social support,resilience,social networks,etc.).By studying the longitudinal changes of cognitive function in the elderly patients with depression,a time-discrete and state-discrete multistate Markov model was constructed,namely,state 1(normal cognitive， NC),state 2(subjective cognitive decline， SCD),State 3(mild cognitive decline，MCI) and State 4(Alzheimer's disease，AD).In-depth analysis of some factors and indicators on the impact of the transfer between the states, the transfer between the states estimated probability.
