Sleep Issues Tied to Alzheimer's, Dementia Risk in Elderly Men

the MPR take:

Insufficient sleep has been linked to brain health in animal and human studies, and new research has found an association between sleep disturbance and risk of dementia and Alzheimer’s disease in older men. In a sample of 1,574 men participating in the Uppsala Longitudinal Study of Adult Men (ULSAM), self-reported sleep disturbance was collected at age 50 and 70 and the mean follow-up overall was 40 years. Overall, men with self-reported sleep disturbances had a 1.33 times greater risk of all-cause dementia during the 40-year observation period compared to men without sleep disturbance, with the association most pronounced for Alzheimer’s dementia. The increased risk for dementia and Alzheimer’s disease was greatest with sleep disturbance reported at age 70 vs. age 50. Regardless of age and gender, a good night’s sleep can be beneficial to your health, but clinicians should pay particular attention to older male patients with sleep disturbance and additional risk factors for dementia and Alzheimer’s disease.

OBJECTIVE: To study the association between self-reported sleep disturbances and dementia risk.
