Light Sensitivity Influences Alzheimer’s Progression

New research heightened light sensitivity in Alzheimer's patients to "sundowning," a worsening of symptoms late in the day, and sleep disruptions that may advance the disease.

This fresh understanding of biological clock disruptions in Alzheimer's could aid the creation of treatments and symptom management. 

Light therapy could potentially regulate erratic sleep patterns caused by altered circadian rhythms.

Further exploration of the disease's effects on the biological clock might also offer preventative strategies.
