Cell studies suggest a way sleep loss may be linked to Alzheimer’s

The immune system may remove the protein plaques in the brain associated with Alzheimer’s disease on a circadian schedule and this could be affected by sleep loss, a study involving mouse cells suggests.

The circadian schedule is an internal clock that controls sleep and a vast array of other bodily processes on a roughly 24-hour cycle. Doctors have long observed that people with Alzheimer’s disease have sleep disturbances and circadian disruption, but it remains unclear the extent to which this disruption could be a cause for the condition itself.
