Sundown Syndromes a psychological phenomenon that cause a variety of behavior, such as confusion, anxiety, aggression or ignoring directions that generally affects people with dementia or cognitive impairment and usually strikes around sunset. Sundowning can also lead to pacing or wandering. Most commonly associated with Alzheimers disease, but also found in those with mixed dementia. The specific causes of sundowning have not been empirically proven but some evidence suggests that circadian rhythm disruption enhances sundowning behavior. There is an association between sundown syndrome and changes in the internal biological clock among people with dementia. The internal clock governed by the circadian rhythms controls sleeping and waking, is connected to how active we are at different times of the day, and influences changes in the body that regulate behavior.
