A map has revealed Britain’s dementia hotspots, with more than one in 35 people affected by the disease in the hardest-hit areas.
Around 2.81 per cent of adults in Christchurch, Dorset are affected by the brain-sapping disease, according to Alzheimer’s Research UK.
Their data shows rates vary widely across the country, with coastal areas in Dorset, Hampshire, Norfolk, Essex and Sussex being particularly affected.
By contrast, in London constituencies where residents are on average younger, the rates were below 0.6 per cent.
Around 944,000 Britons are currently living with dementia and experts predict the number will surpass one million by the end of the decade.
Alzheimer’s is the most common form of the disease and is thought to be caused by the buildup of proteins in the brain, including tau and amyloid.
Data from Alzheimer’s Research UK shows that there are more than 1,900 residents living with dementia in several general constituencies across the UK.
On average, around 1.33 percent of the population was affected.
After Christchurch, the prevalence was highest in New Forest West in Hampshire, where 2.65 per cent have the disease.
It was followed by North Norfolk (2.44 percent), Clacton in Essex (2.43 percent) and Worthing West in West Sussex (2.42 percent).
In contrast, the condition is lowest in Poplar and Limehouse in London, where it affects 0.38 per cent.
This comes as researchers published results for the strongest Alzheimer’s drug yet to be proven to slow the disease — ushering in “a new era in which it could become treatable.”
In tests, donanemab rids the brain of 84 percent of toxic amyloid plaque proteins and delays mental decline by up to 60 percent.
It is the second drug shown to reverse the process, after lecanemab was shown last year to slow the decline by 27 percent.
