Myth: dementia is just being forgetful

Fact: dementia is not just forgetfulness.

Dementia affects everyone uniquely. It can affect your thinking, mood and behaviour as well as memory, enough to interfere with your social or work life.

Memory loss in dementia is different from sometimes forgetting things. It is persistent and progressive, not just occasional.
