What is sundowning in dementia?

Sundowning refers to behavior problems that worsen in the late afternoon and evening. No one knows exactly why sundowning occurs, though there are several theories. Because people are tired at the end of the day, their tolerance for stress declines, and a minor problem can generate a major outburst. An already confused person may be overstimulated when several people are in the house, dinner preparations are under way, and the television is on. Dim light may also contribute to a person's misinterpretation of visual information.

Sundowning refers to the worsening of dementia later in the day. It is not entirely known why this is the case but sundowning is very common in dementia.
