Which term describes the worsening of dementia symptoms in the late afternoon and evening?

The term that describes the worsening of dementia symptoms in the late afternoon and evening is "sundowning." This phenomenon is commonly observed in individuals with dementia and refers to increased confusion, agitation, and behavioral issues that occur as the day progresses into the evening. The exact causes of sundowning can vary, but factors such as changes in natural light, fatigue, and disruptions in the individual's routine are believed to contribute to this pattern.

Sundowning can significantly impact the well-being of individuals with dementia and poses challenges for caregivers. Understanding and identifying this symptom can help in developing strategies to mitigate its effects, such as creating a calming environment during the evening hours or maintaining a consistent daily routine.
