The authors of a recent study published in Alzheimer’s and Dementia Journal examined the “association between self-reported sleep disturbances and dementia risk.” The authors conducted a longitudinal study that followed 1574 men for up to 40 years. The study determined dementia incidence by reviewing their patient history between ages 50 and 90 years. The authors found that “men with self-reported sleep disturbances had a higher risk of developing dementia and Alzheimer’s than men without sleep disturbances,” and concluded that improved sleep quality may help reduce the risk of Alzheimer’s and dementia in older men.
