Dementia symptoms often worsen at night due to a phenomenon called sundowning, caused by a disrupted internal body clock, fatigue, changes in light, and confusion between dreams and reality, leading to increased anxiety, confusion, and agitation as daylight fades, though it can also signal underlying issues like infection, pain, or overstimulation.

What type of dementia is worse at night?

Medications like cholinesterase inhibitors (Donepezil, Rivastigmine, Galantamine) and NMDA receptor blockers (Memantine) can temporarily improve symptoms of Alzheimer's and other dementias by boosting brain chemicals, while newer anti-amyloid therapies (Lecanemab, Donanemab) slow decline in early Alzheimer's by clearing plaques, but no current drug stops dementia, only managing symptoms and potentially slowing progression for some people.
 

How do you prevent Sundowning?

To prevent sundowning, establish a predictable daytime routine with plenty of natural light and activity, then create a calm, well-lit, and less stimulating environment in the evening with soft music and familiar objects, while avoiding caffeine, alcohol, and large meals late in the day to reduce confusion and agitation. Keeping a consistent schedule helps regulate the body clock and provides reassurance for people with dementia, but always talk to a doctor about potential underlying issues like pain or medication side effects.
