Often, due to the affects of the disease on the brain, patients with Alzheimer's disease have disturbed wake/sleep cycles with increased napping during the day, followed by sundowning (where patients become more agitated or confused in the late afternoon/evening), and then not sleeping well or waking up a lot in the evening. Some of this may be mediated by keeping patients with Alzheimer's disease awake during the day as much as possible, only 1 1hr nap at most, and attempting to find a stimulating environment, whether this be an adult day health program or activities that stimulate a patient with this disease physically and/or mentally.
