Sundowning

Sundowning, also know as sundown syndrome, is associated with Alzheimer's disease or mixed dementia in elderly patients. Symptoms of sundown syndrome are confusion and restlessness as well as behavioral problems. Sundowning generally occurs in the mid-phase of Alzheimer's disease or mixed dementia and affects 20-45% of Alzheimer's patients. Most patients who have this syndrome recognize and understand that their behavior is abnormal. These symptoms seem to subside as a patient progresses farther into dementia.
