North Norfolk has the third highest proportion of people living with dementia in the country.

The area was named in a new list of dementia hotspots revealed in interactive maps.

The coastal constituency came joint third, with Clacton in Essex and Worthing in West Sussex.

The maps - which can be accessed here - show the regions most affected by dementia, with coastal towns and areas popular with retired people featuring heavily in the list.

In north Norfolk there are 2,109 living with dementia, compared to an average of 1,302.

That was equivalent to 24 cases per 1,000 people.

The five constituencies with the lowest levels of dementia were mostly in London.

There are currently 850,000 people living with the dementia in the UK but this is expected to rise to one million by 2025 as people live longer.

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.

'As the UK's leading dementia research charity, one of our biggest challenges is to empower people with the knowledge that this cruel and unforgiving condition can be defeated.

'Dementia is not an inevitable part of ageing, it is caused by diseases.'
