Sundown syndrome is a behavior that is described as confusion, anxiety, agitation, or disorientation that often occurrs at dusk and into the evening hours. The episodes may last a few hours or throughout the night.

While the cause is unknown, experts believe there are several contributing factors. These include physical and mental exhaustion, and a shift in the "internal body clock" caused by the change from daylight to dark. Some people havw trouble sleping at night, which may contribute to their disorientation. Medication that can cause agitation or confusion also may contribute to the syndrome.

Here are some suggestions.
