Behaviours and how to respond
When the person you love does things that don’t make sense.
Dementia changes behaviour in ways that can be confronting, exhausting and sometimes frightening. Almost always, behaviour is a form of communication — they are trying to say something they no longer have the words for.
Behaviour is a message
Before reacting, ask: are they in pain? Hungry? Thirsty? Tired? Too hot or cold? Needing the toilet? Frightened by the room? Bored? Lonely? Most “difficult” behaviour is one of these unmet needs they can no longer name.
Wandering
Walking, pacing, leaving the house — often they are looking for something familiar (a childhood home, a parent, a job they had decades ago). Safety matters: an ID bracelet, a tracker, a safe route, alerts on the front door. But also ask what they’re searching for, gently.
Anger and agitation
Anger in dementia is rarely personal. It is usually overwhelm. Lower the noise. Lower the lights. Lower your own voice. Step back, give space, and try again in a few minutes. Don’t take it home with you, even when it’s aimed at you.
Hallucinations and delusions
Some people with dementia see things that aren’t there, or hold beliefs that don’t match reality (people stealing from them, partners being unfaithful). These can be deeply distressing for them. Don’t argue. Validate the feeling: “That sounds really frightening. I’m here. You’re safe with me.”
Sundowning
Many people with dementia become more confused, restless or distressed in late afternoon and evening. This is called sundowning. It can help to keep evenings calm — soft lighting, familiar music, light meals, fewer visitors, a regular wind-down routine.
