Newham has one of the lowest proportion of people with dementia than any other area in the UK.

Figures from Alzheimer’s Research UK show that just 0.51 per cent of those living in the East Ham constituency have dementia - or, in real terms, 808 people.

The borough’s other constituency,West Ham, was in the five areas with the lowest levels of dementia.

There, just 0.48pc of people have the condition - equating to 840 people.

The areas with the highest prevalence typically have between 1,500 and 2,700 people suffering dementia.

Christchurch in Dorset has the most, with 2.81pc, with nearby New Forest West close behind with 2.65pc.

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.”
