Tailored light treatment will increase sleep efficiency, reduce depression and reduce agitation scores in those with Alzheimer's disease and related dementia


In a within subjects, randomized placebo control study, a tailored light treatment will be used for short-term (4 weeks). Outcome measures include sleep measures (actigraphy), and questionnaires probing behavior and mood in those who have been diagnosed with Alzheimer's disease and related dementia. After a 4-week washout period, a placebo control inactive light will be used for another 4 weeks.
