Body clock disruptions occur years before memory loss in Alzheimer's

(Washington University School of Medicine) People with Alzheimer's disease have disturbances in their internal body clocks that affect the sleep/wake cycle and may increase risk of developing the disorder. Researchers at Washington University School of Medicine in St. Louis have found that such circadian rhythm disruptions also occur much earlier in people whose memories are intact but whose brain scans show early, preclinical evidence of Alzheimer's.
