How does sundowning affect individuals with Alzheimer disease?

Sundowning refers to a phenomenon often observed in individuals with Alzheimer's disease where their confusion, agitation, and other cognitive symptoms tend to worsen during the late afternoon and evening hours. This can manifest as increased anxiety, restlessness, or even aggressive behavior as daylight diminishes. The exact cause is not entirely understood, but it may be related to changes in the internal body clock, fatigue, or the effects of reduced light in the environment, which can be disorienting.

The correct understanding of sundowning highlights the challenges caregivers and healthcare professionals face in managing these symptoms, especially during the time when patients might typically be winding down for the day. Recognizing that symptoms can intensify at night suggests the need for tailored strategies to provide a calming environment and ensure safety for individuals experiencing this condition.
