Claim 1 of 5Not checkedPeople with type 2 diabetes, heart disease or stroke who sleep well have better cognitive function and greater brain volume than people with the same conditions who sleep poorly, according to a new study from Karolinska Institutet.View evidenceHide evidence

Not checked

No source study was confirmed for this article. This claim remains unverified, rather than assessed as supported or unsupported.

Claim 2 of 5Not checkedResearchers investigated whether healthy sleep can mitigate the associations between cardiometabolic diseases and increased risk of cognitive decline and dementia, and the results were presented in the Journal of the American Heart Association.View evidenceHide evidence

Claim 3 of 5Not checkedIn UK Biobank data from over 400,000 middle-aged and older adults, including just over 54,000 with at least one cardiometabolic disease and MRI data for nearly 35,000 participants, sleep was assessed using five self-reported factors: sleep duration, circadian rhythm, insomnia, snoring and daytime sleepiness.View evidenceHide evidence

Claim 4 of 5Not checkedPeople with cardiometabolic disease who slept well performed slightly better on tests of general cognition, problem-solving ability and processing speed, and had significantly larger total brain volume and greater grey and white matter volumes than those who slept poorly.View evidenceHide evidence

Claim 5 of 5Not checkedThe link between sleep and brain structure was more pronounced in people with type 2 diabetes, heart disease or stroke than in those without these conditions, and the researchers said improving sleep may be an accessible and achievable goal.View evidenceHide evidence
