Actual (reported)Aim 2 will investigate the effect of 3 different light exposure lengths on sleep, mood and agitation in persons with Alzheimer's disease. Participants will be randomly assigned to one of three conditions of light exposure: 1) 2-h morning light exposure; 2) 4-h morning light exposure; and 3) all day light exposure.

Actual (reported)Sleep Disturbance using the Pittsburgh Sleep Quality Index
The PSQI is used to measure sleep quality and is composed of 19 items that generate 7 component scores (subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication, and daytime dysfunction). Each subscale is scored 0 to 3. The sum of the 7 component scores yields a single global score with a range of 0 to 21. A higher score indicates higher sleep disturbance
