2. Dementia isn’t a natural part of ageing

Dementia doesn’t care who you are and can affect anyone.

It’s caused by diseases of the brain which includes Alzheimer’s disease.

Dementia affects everyone differently.

Someone with the condition might experience a number of changes including problems with memory, thinking, concentration and language.

It mainly affects people over the age of 65 however there are more than 42,000 people under 65 living with dementia in the UK.

3. Dementia is a progressive condition but with support people can continue to live well

Dementia is progressive, meaning that symptoms gradually get worse.

However, many people living with dementia lead active and fulfilling lives for many years.

There are many ways to help support someone living with dementia from becoming a Dementia Friend, gaining a better understanding of the condition, to volunteering with Alzheimer’s Society’s Side by Side service.

4. By 2021, one million of us will have dementia

There are 850,000 people in the UK who have a form of dementia, of which 14,000 live in Hertfordshire.

Dementia has replaced heart diseases as the leading cause of death in England and Wales, accounting for 11.6% of all deaths registered in 2015, according to the Office for National Statistics.

Dementia is set to be the 21st century’s biggest killer, with someone developing it every three minutes.

5. There is no cure for dementia

Delaying the onset of dementia by five years would halve the number of deaths from the condition, saving 30,000 lives a year.

Of the top 10 causes of death, dementia is the only one we can’t prevent, cure or even slow down, but funding of dementia research is still far too low.

Research is continuing into new drugs, vaccines and other medical treatments.

Drugs do exist for Alzheimer’s disease which can improve symptoms or temporarily slow progression, in some people.

There are no licensed drug treatments for other forms of dementia.

6. Dementia research is underfunded

Dementia research is desperately underfunded. For every person living with dementia, the annual cost to the UK economy is over £30,000 and yet only £90 is spent on dementia research each year.

Alzheimer’s Society is committed to spending at least £150 million over the next decade on dementia research including a £50 million investment in the UK’s first dedicated Dementia Research Institute.
