As the late afternoon light begins to fade, many family caregivers notice a distinct shift. A parent or partner who seemed relatively calm, cooperative, or clear-headed during breakfast suddenly becomes restless, anxious, or suspicious around 4:00 or 5:00 PM.

This daily phenomenon is widely known as sundowning (or sundowner’s syndrome). It is not a standalone diagnosis, but rather a pattern of neurological symptoms that flare up in the late afternoon and evening, most commonly in individuals living with Alzheimer’s disease or other forms of dementia.

If you are navigating this as a caregiver, understanding why it happens and how to manage the environment can make evening transitions far smoother for everyone involved.
