The areas hardest hit by dementia in the UK have been revealed in two interactive maps launched by Alzheimer’s Research UK – with a town in Dorset named as the worse affected area. 

Currently, there are 850,000 people in the UK living with the dementia and this number is set to soar to one million by 2025.

Public understanding of the condition is still low – and despite recent increases in funding, research into the condition still lags behind other serious conditions.

Alzheimer’s Research UK, the UK’s leading dementia research charity, has developed the new online tool ahead of a parliamentary information session, to highlight to MPs, policymakers and the wider public, the importance of keeping dementia high on the political agenda.

According to the data, coastal constituencies in the south of England have the highest number of people living with dementia per head of population – with Christchurch, in Dorset, topping the list.

In this constituency, 2,400 people have dementia, which is 2.8 per cent of its overall population – more than double the country’s average of 1.3 per cent.

The five constituencies with the highest prevalence of dementia, per head of population are:

Christchurch                             28 per 1,000 people.

New Forest West                      27 per 1,000 people.

North Norfolk                            24 per 1,000 people.

Clacton                                     24 per 1,000 people.

Worthing West                          24 per 1,000 people.

The five lowest were:

Poplar and Limehouse               4 per 1,000 people.

West Ham                                  5 per 1,000 people.

Bethnal Green and Bow             5 per 1,000 people.

Manchester Central                    5 per 1,000 people.

Hackney South and Shoreditch  5 per 1,000 people.

On Thursday, October 19, the charity will team up with global pharmaceutical company, MSD, to host a Parliamentary information session for MPs. MPs attending will hear about the impact of dementia in their constituency and learn how they can help defeat the condition.

Dr Matthew Norton, director of policy at Alzheimer’s Research UK, said: “Dementia is our greatest medical challenge and with our ageing population, the number of people affected by this devastating condition is only going to rise.

"Today, one in three people have a family member or close friend with dementia. Despite this, there is still a worrying lack of public understanding about the condition, which is why we have developed the dementia hotspots maps."
