Understanding Sundowning
Sundowning refers to increased confusion and agitation that occurs in the late afternoon and evening among dementia patients. It is thought to be related to changes in circadian rhythms, which are the natural cycles of wakefulness and sleep. Up to two-thirds of dementia patients may experience sundowning, impacting their overall quality of life and that of their caregivers.
Causes of Sundowning
Several factors may contribute to sundowning, including poor light exposure, which can disrupt sleep patterns and worsen agitation. Additionally, discomfort or pain, medication side effects, and environmental changes can exacerbate symptoms. Understanding these triggers can help in managing sundowning more effectively.

Managing Sundowning
Nonpharmacologic strategies are often preferred to manage sundowning, such as maintaining a regular daily routine and ensuring exposure to natural light during the day. Gentle activities like listening to calming music or engaging in a simple task can also provide comfort and reduce agitation.
