Sundowning in Dementia: Managing Evening Agitation and Confusion

Sundowning is a phenomenon that affects many individuals with Alzheimer's disease and other forms of dementia. As daylight fades in the late afternoon and evening, affected individuals may become increasingly agitated, confused, anxious, or even aggressive. The Alzheimer's Association estimates that sundowning affects up to 20 percent of people with dementia, creating one of the most challenging periods of the day for family caregivers.

While researchers are still studying the exact cause, contributing factors include fatigue from the day's activities, changes in the body's internal clock, reduced lighting that creates shadows and visual confusion, unmet needs such as hunger or pain, and overstimulation throughout the day. Certain medications can also worsen symptoms during evening hours.

Managing sundowning starts with establishing a predictable daily routine. Keep afternoons calm and avoid scheduling demanding activities late in the day. Increase indoor lighting before sunset to reduce shadows that can cause confusion. Limit caffeine and sugar after noon. Play soothing music or engage in gentle activities like looking through photo albums during the late afternoon transition period.

Track sundowning episodes in a care log noting what happened before, during, and after each episode. Patterns often emerge that reveal specific triggers. Share these observations with your care team through www.FamilyCare.Help so everyone providing care can maintain consistent evening routines. If sundowning becomes severe, consult the doctor about whether medication adjustments might help.
