Full Definition
Sundowning, also known as sundown syndrome, refers to the tendency for individuals with dementia to experience heightened confusion, agitation, anxiety, or restlessness during late afternoon and evening hours. This phenomenon affects up to 20% of people with Alzheimer's disease and other dementias. The exact cause is not fully understood but may relate to disrupted circadian rhythms, fatigue, reduced lighting, or changes in routine. Healthcare providers often adjust care plans and medications to manage sundowning episodes.
