Here are some facts we do know:
- The illnesses that cause dementia don’t spread from person to person. You don’t have to worry about ‘catching’ dementia from someone else.
- Not all older people get dementia. For every 1000 people older than 65, around 18 will develop dementia each year.
- The younger a person is, the less likely they are to have dementia.
- Most people who have dementia become ill when they are in their late 60s, 70s, 80s or 90s.
- Sometimes a person who is younger than 65 gets an illness that causes dementia, but this is less common. It is called early-onset or young-onset dementia.
- Around 850,000 people in the UK are living with dementia (that’s around 1.3% of the whole population).
- Around 40,000 of these people are younger than 65. That means for every 100 people with dementia in the UK, two are younger than 65.
