The prevalence of sundowning (including probable sundowners) was 24%. Sundowners and non-sundowners differed with regard to number of sedatives received daily, particularly chloral hydrate, and the number of days on the inpatient unit. There were no differences between sundowners and non-sundowners with respect to other types of medications, medical diagnoses, current age, age of onset of Alzheimer's disease, or Mini-Mental State Exam. Restlessness was the most common sundowning behavior, although multiple behavioral disturbances were seen. This survey suggests that the sundown syndrome is a common problem in severely demented Alzheimer's patients and requires further study.<\/jats:p>","DOI":"10.1177\/089198879500800205","type":"journal-article","created":{"date-parts":[[2014,3,18]],"date-time":"2014-03-18T19:53:09Z","timestamp":1395172389000},"page":"103-106","source":"Crossref","is-referenced-by-count":60,"title":["Sundown Syndrome in Severely Demented Patients with Probable Alzheimer's Disease"],"prefix":"10.1177","volume":"8","author":[{"given":"John T.","family":"Little","sequence":"first","affiliation":[{"name":"Biological Psychiatry Branch (Dr. Little), NIMH, Bethesda, Maryland; Harvard Medical School and McLean Hospital (Dr. Satlin), Belmont, Massachusetts; Section On Geriatric Psychiatry, Laboratory of Clinical Science (Dr. Sunderland), NIMH, Bethesda, Maryland; and Boston University School of Medicine and E.N.
