Less information is available about the temporal relationship between depression in the elderly and cognitive decline. In the current study, we (1) evaluated the temporal association between depression and cognitive decline in older adults over a 4-year period; (2) indicated which cognitive domains have a strong temporal relationship with depression. Using data from China Family Panel Studies, we examined the relationship between depression and cognition among adults aged 65 and older with a cross-lagged design. The results showed that initial depression affected subsequent cognitive function, especially immediate and delayed recall, but that cognition decline did not predict depression over time. The findings suggest that depression precedes cognitive decline in older adults, which is of great significance for the future research of mild cognitive impairment and dementia in the elderly.
关于老年人抑郁和认知能力下降之间的时间关系，相关信息较少。在本研究中，我们（1）评估了老年人在 4 年内抑郁和认知能力下降之间的时间关联；（2）指出哪些认知领域与抑郁有很强的时间关系。我们使用中国家庭追踪调查的数据，采用交叉滞后设计研究了 65 岁及以上成年人中抑郁与认知之间的关系。结果表明，最初的抑郁会影响随后的认知功能，尤其是即时和延迟回忆，但认知下降不会随着时间的推移预测抑郁。这些发现表明，抑郁先于老年人的认知能力下降，这对未来老年人轻度认知障碍和痴呆的研究具有重要意义。
