The silent alarm: How your body’s internal clock could hold the key to preventing dementia
A 2025 study found that older adults with strong, consistent circadian rhythms had their risk of developing dementia nearly halved, suggesting rhythm strength is a critical independent factor for cognitive health.
The circadian rhythm acts as a master conductor for the body, coordinating hormones, body temperature, cellular repair and sleep-wake cycles—not just sleep duration.
Research indicates that weakened or erratic daily rhythms are a significant dementia risk factor, with each step down in rhythm strength linked to a 54% increase in risk and a later daily activity peak also raising risk.
The connection likely involves multiple biological pathways, including impaired clearance of brain toxins (like amyloid beta) during sleep and increased systemic inflammation when circadian signals are disrupted.
While a weakening body clock may be either an early cause or a symptom of dementia, preserving circadian health through consistent routines is highlighted as a crucial, yet complex, preventive measure, as simple sleep aids have not proven effective.
