Sleep difficulties in dementia create discomfort and may leave families unable to care for a loved one at home. Recent Cochrane studies discovered no therapies with established efficacy.

The present paper updates this review by taking into account fresh studies on therapies for sleep disorders or anomalies of the sleep-wake cycle in community-dwelling adults with dementia.
