Research links disrupted biological rhythms to dementia risk, but sleep length alone may not be the key factor.

Your daily rhythm may matter more for brain health than previously thought. Older adults with weaker, more disrupted activity ...

New research suggests that the strength and timing of the body’s internal clock may be closely tied to dementia risk.

Weakened and fragmented circadian rhythms may be associated with an increased risk of dementia in the elderly. This was ...

Delayed body clock rhythm is associated with 2.5 times more dementia risk. Routine light therapy may help reinforce circadian ...

The results of a recent study suggest that people with a weaker or more irregular body clock, also known as circadian rhythm, ...

Elevated dementia risks among older adults were associated with weaker and more fragmented circadian rest-activity rhythms ...

And those who experienced peak activity later in the afternoon — from 2:15 p.m. onward — had a 45% higher risk of dementia ...

“Changes in circadian rhythms happen with aging, and evidence suggests that circadian rhythm disturbances may be a risk factor for neurodegenerative diseases like dementia,” said Dr. Wang.

A study suggests that a person’s internal body clock may influence dementia risk, with weaker circadian rhythms — ...
