Understanding Sundowning in Dementia Patients

If you care for someone with Alzheimer's or another form of dementia, you may have noticed that their confusion, agitation, or anxiety seems to worsen in the late afternoon and evening. This phenomenon is known as sundowning — and it affects up to 20% of people with Alzheimer's disease.

What is sundowning?

Sundowning (also called sundown syndrome) refers to a pattern of increased confusion, restlessness, agitation, and behavioral changes that typically begin in the late afternoon and continue into the evening. It is not a disease in itself but a cluster of symptoms associated with dementia.

Common sundowning behaviors

• Increased confusion and disorientation
• Agitation, anxiety, or irritability
• Pacing, wandering, or restlessness
• Suspicion or accusations toward caregivers
• Seeing or hearing things that aren't there
• Difficulty sleeping or refusing to go to bed
• Yelling, crying, or calling out repeatedly

Why does sundowning happen?

The exact cause isn't fully understood, but several factors likely contribute. Dementia disrupts the brain's internal clock, making it harder to regulate the sleep-wake cycle. Fatigue that accumulates throughout the day, low lighting as dusk approaches, and hunger or discomfort can all trigger or worsen symptoms.

Strategies that help

While sundowning cannot be cured, there are evidence-based strategies that can reduce its frequency and severity.

• Maintain a consistent daily routine — predictability reduces anxiety
• Maximize natural light exposure during the day and keep evenings calm and dimly lit
• Schedule the most stimulating activities for the morning, not late afternoon
• Ensure adequate rest during the day without excessive napping
• Offer a light snack in the late afternoon — hunger can trigger agitation
• Play soft, familiar music during the typical sundowning window
• Reduce background noise and television during evening hours
• Avoid arguing or trying to reason during an episode — redirect gently instead

Supporting caregivers through sundowning

Sundowning is exhausting for caregivers. The unpredictability and the emotional weight of managing repeated episodes — often at the end of an already long day — can take a serious toll. Respite care during the late afternoon and evening hours can provide meaningful relief. Wellstead caregivers trained in memory care can help manage sundowning behaviors with patience, skill, and compassion.
