Sleep Issues and Sundowning

by Liz DeSantis

Scientists don’t completely understand why sleep disturbances occur with Alzheimer’s disease and dementia. As with changes in memory and behavior, sleep changes somehow result from the impact of Alzheimer’s on the brain.

Some studies indicate as many as 20 percent of persons with Alzheimer’s will experience increased confusion, anxiety and agitation beginning late in the day. Others may experience changes in their sleep schedule and restlessness during the night. This disruption in the body’s sleep-wake cycle can lead to more behavioral problems.
