Sleep disturbances and cognition are linked in people with cerebrovascular disease
A systematic review found associations across several sleep problems and thinking skills, without showing that treating sleep problems prevents cognitive decline.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
Sleep apnea, disrupted sleep, sleep quality and total sleep time were associated with cognition in people with cerebrovascular conditions. The reported links involved overall thinking ability and specific skills, including memory and verbal fluency. This review identifies relationships worth studying; it does not establish that sleep disturbances caused the cognitive problems.
The abstract gives no pooled effect sizes, follow-up periods or study-level quality ratings. It therefore cannot show how strong, consistent or temporally ordered the associations were.
Sleep problems and cognitive associations
The review separated the presence of sleep problems after stroke from their associations with cognition. Frequently reported problems included breathing-related disorders, insomnia and daytime sleepiness, while the cognitive findings concerned several specific sleep features.
Who the findings concern
Memory, attention and verbal fluency appeared among the reported cognitive domains. Because the review concerns people with cerebrovascular disease, these findings should not be generalized to everyone who sleeps poorly or notices occasional forgetfulness.
