A MAP has revealed Britain’s dementia hotspots, with more than one in 35 people hit with the disease in the worst-affected areas.
Around 2.81 per cent of adults in Christchurch, Dorset, have been struck down with the brain-robbing condition, 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 particularly affected.
In contrast, constituencies in London, where residents tend to be younger on average, had rates of less than 0.6 per cent.
Around 944,000 Brits are currently living with dementia and experts predict the numbers will exceed 1million by the end of the decade.
Alzheimer’s is the most common form of the condition, and is thought to be caused by build-ups of proteins in the brain, including tau and amyloid.
The Alzheimer’s Research UK data shows several parliamentary constituencies across Britain have more than 1,900 residents living with dementia.
On average, around 1.33 per cent of the population had it.
After Christchurch, 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 per cent), Clacton in Essex (2.43 per cent) and Worthing West in West Sussex (2.42 per cent).
In contrast, the condition is rarest in Poplar and Limehouse in London, where 0.38 per cent have it.
It comes as researchers released results for the most powerful Alzheimer’s drug yet to be proven to slow the disease — heralding “a new era where it could become treatable”.
Donanemab rid the brain of 84 per cent of toxic amyloid plaque proteins in tests and held up mental decline by up to 60 per cent.
It is the second drug proven to reverse the process after lecanemab was shown to slow decline by 27 per cent last year.
