Sundowning is a phenomenon often observed in individuals with Alzheimer's disease or other forms of dementia. It typically occurs in the late afternoon or evening, when affected individuals may experience increased confusion, agitation, or restlessness. This behavior can be triggered by fatigue, changes in lighting, or the end of daily routines. During sundowning, caregivers may notice that the person becomes more irritable or may have difficulty communicating. It is important for caregivers to create a calm environment, maintain a consistent routine, and provide reassurance to help manage these symptoms effectively.
