Sundowning: when evenings get hard — and what actually helps

If late afternoon turns your calm parent anxious, angry, or determined to "go home" (while standing in their own living room), you're seeing sundowning — one of the most common and least-warned-about parts of dementia care. You're not doing anything wrong. And there are things that help.

What it is

Sundowning is a pattern of increased confusion, agitation, or restlessness in the late afternoon and evening. Nobody fully knows why it happens — likely some mix of a disrupted body clock, fading light and harder-to-read shadows, fatigue accumulated across the day, and a brain running out of resources to manage it all. Knowing it's a recognized pattern matters: it's the disease, not defiance, and not your failure.

What families say actually helps

• Light, before it's needed. Turn lights on in mid-afternoon, before dusk — shadows and dim rooms feed confusion. Brighter days (real daylight, a morning walk) seem to help evenings.
• Protect the afternoon. Schedule appointments, baths, and anything demanding for morning. Aim the afternoon at calm: quiet activity, a rest that's not a long nap.
• An evening ritual, same order every day. Predictability is medicine. Same music, same chair, same warm drink (watch caffeine after lunch — including tea and chocolate).
• Don't argue with the reality. "I have to go home" rarely responds to "you are home." Respond to the feeling underneath — "you're safe, I'm here, let's have tea first" — then redirect. Arguing escalates; agreeing-and-redirecting de-escalates.
• Check the basics. Hunger, thirst, pain, and needing the bathroom all masquerade as agitation in someone who can't say so.
• Lower the evening volume. TV news, overlapping conversations, and clattering dishes read as chaos. One calm thing at a time.

Track it — patterns are power

Note when it starts, what preceded it, what helped. Two weeks of notes often reveals a trigger (a 4pm nap, a loud show, an empty stomach) — and gives the doctor something real to work with. This is exactly what a between-appointments record is for; the free Annie app makes it a 20-second habit.

When to involve the doctor

If evenings become unsafe, if sundowning appears suddenly (sudden worsening can signal something treatable, like a urinary tract infection), or if nobody in the house is sleeping — call the care team. Bring your notes. There are medical options; there are also risks — that conversation deserves data.

And you

Sundowning hits at the exact hour your own tank is empty. If evenings are the hardest shift, that's the shift to hand off first — a helper, a family member, funded respite. You don't win a prize for taking the worst hours alone.
