What is cognitive impairment?

Cognitive impairment is not an illness, but a description of someone's condition. It means they have trouble with things like memory or paying attention. They might have trouble speaking or understanding. And they might have difficulty recognising people, places or things, and might find new places or situations overwhelming.

Family and friends might notice that someone with cognitive impairment is confused, or agitated, or very moody. They might notice a change in their speech or behaviour, or that they have difficulty with their usual daily tasks.
