Disturbed Circadian Rhythm May Be Associated With Alzheimer’s Disease

Long-term circadian rhythm disruptions induce Alzheimer's disease-like pathology in rats, which can be reversed by administering fluoxetine. Additionally, elevated levels of amyloid beta and circadian rhythm disruptions can trigger each other, leading to the cascade of neurological symptoms of dementia.

Molecular switch mechanism explains how mutations shorten biological clocks

Study reveals how certain genetic mutations can shorten the timing of the circadian clock, making some people extreme "morning larks" because their internal clock operates on a 20-hour cycle, as opposed to a 24-hour cycle.
