Full Definition
Sundown syndrome refers to a phenomenon commonly observed in individuals with dementia, characterized by increased confusion, restlessness, agitation, and other behavioral disturbances that typically begin in the late afternoon or early evening. The exact cause is not fully understood, but it may be related to disruptions in circadian rhythms, fatigue, reduced lighting, or increased shadows. Healthcare providers often implement environmental modifications and structured routines to manage these symptoms.
