这项研究检查了老年人睡眠质量和认知能力之间的关系，控制了常见的医学合并症。参与者是社区志愿者，虽然不是根据他们的睡眠选择的，但他们确实报告了睡眠质量的巨大差异。睡眠好的人和睡眠差的人在工作记忆、注意力转移和抽象问题解决方面存在差异，但在处理速度、抑制功能或情景记忆方面没有差异。睡眠不好也与抑郁性精神病的增加有关，但仅与功能性症状有关（例如，浓度降低）而不是情绪（例如，悲伤）。睡眠质量和认知之间的关系不能用诸如脑血管疾病、抑郁症或药物使用等混杂因素来解释。睡眠问题可能会导致老年人之间的表现差异，但仅在某些认知领域。
This study examined the relation between sleep quality and cognitive performance in older adults, controlling for common medical comorbidities. Participants were community volunteers who, while not selected on the basis of their sleep, did report substantial variability in sleep quality. Good and poor sleepers differed on tests of working memory, attentional set shifting, and abstract problem solving but not on processing speed, inhibitory function, or episodic memory. Poor sleep was also associated with increased depressive symptomatology but only for functional symptoms (e.g., decreased concentration) and not for mood (e.g., sadness). The relationships between sleep quality and cognition were not explained by confound factors such as cerebrovascular disease, depression, or medication usage. Sleep problems may contribute to performance variability between elderly individuals but only in certain cognitive domains.
