Sundown syndrome

Sundown syndrome is a year-round condition affecting the elderly, and it is linked to the hours before sunset. The symptoms are increased agitation and confusion in late afternoon and early evening. The syndrome may be related to the seasonal affective disorder (SAD) and is thought to be depressive in nature.
It was previously thought that only senile patients had the Sundown syndrome, but in 1997 it was shown that elderly people with normal cognitive functioning also had it.
