Poor Sleep Quality Linked To Alzheimer’s
Poor sleep quality, specifically what experts refer to as “sleep-wake problems”, are a common symptom of Alzheimer’s disease, even in a preclinical stage. This poor sleep quality, which can even be observed in cases of mild cognitive impairment, is believed to be caused by a build up of beta-amyloid in the brain. To expand this information, you can infer that poor sleep quality can be an early indicator of the onset of Alzheimer’s.
Mary Ann Moon reports for Clinical Psychiatry News that it is this sleep quality, not sleep quantity, that can be an indicator of cognitive impairment. Understandably in the study, individuals who reported taking three or more naps per week were the individuals who generally had a lower quality of sleep each night and were therefore more likely to show deposits of beta-amyloid in their brain.
