Poor sleep can increase risk of Alzheimer's, says study

Poor sleep among older people suggests that it's an indication of increased risk for Alzheimer's

Poor sleep may be an indication of increased risk for Alzheimer’s disease, a new study conducted with older people suggests.

Researchers studied 101 cognitively normal people, average age 63, who completed well-validated sleep questionnaires. They analyzed their spinal fluid for the presence of indicators of the plaques and tangles that are characteristic of Alzheimer’s. The study is in Neurology.
 

After controlling for age, a family history of Alzheimer’s, the ApoE gene that increases Alzheimer’s risk and other factors, they found that poor sleep quality, sleep problems and daytime sleepiness were associated with increased spinal fluid indicators of Alzheimer’s disease.
