Light therapy for sleep and memory in older adults

This trial studies rhythmic light therapy to help people with early Alzheimer’s or mild memory problems, especially when sleep is getting worse. If you fit the sleep and vision/medical safety requirements, the study may see whether the therapy improves sleep and thinking-related symptoms.

This study tests if a program that combines light physical activity with simple mental tasks can help improve memory and thinking in people with mild cognitive impairment (MCI). It is for people who are not already exercising regularly and do not take memory medications.

This study tests whether changing the light in a hospital room can improve sleep and help your body clock work better in older adults. It may be most helpful if sleep problems or irregular daily rhythms are affecting you in the hospital.

This study tests whether light therapy can help people sleep better after a traumatic brain injury (TBI). Researchers will use MRI brain scans and sleep tracking to see if light therapy changes how your brain clears toxins during sleep.
