Actigraphies were recorded total of 4 weeks for each patient (average 30 minutes per day, around 3.00 pm, from 50 cm distance and 1000 lux over 7 days). The sleep and light application forms were filled. After than, actigraphies of patients were recorded over the third and fourth weeks. Results: There was a significant difference for the sleep durations (p<0.05) and the inactivity status (p=<0.001) in patients with Alzheimer’s disease who were applied light , however no significant difference was found for the intensity of activities (p>0.05).
