Summary

This pilot study will test whether bright light therapy can help reduce behavioral and psychological symptoms like agitation in people with dementia. Researchers plan to enroll 70 adults on inpatient units at Mayo Clinic. Participants will receive 60-minute sessions of light therapy three times daily for five days using a Verilux HappyLight. The main goals are to see if the approach is feasible, acceptable, and tolerable.
