Analysis of NHS data has revealed that rates of people being diagnosed with dementia have more than doubled in some parts of the country over five years.
The BBC analysis of the latest NHS data shows dementia diagnoses in England, Wales and Northern Ireland rose by 40% between 2014 and 2019 to 508,000 people. A further 90,000 people are believed to be living with dementia in Scotland.
Professor Sube Banerjee, from Plymouth University’s Faculty of Health, said the rise was partly due to NHS England’s drive to increase diagnoses rates.
He said a targeted 67% diagnoses rate set out in the National Dementia Strategy in 2012 had been achieved.
As of March around 1% of people in England, Wales and Northern Ireland were on the dementia register, however, research indicates many more people have not yet been diagnosed.
Dementia hot spots, where rates have more than doubled over the last five years, include Surrey, Lincolnshire, Bexley, Canterbury, Dartford and Gravesham.
Additionally, rates in Ayrshire and Arran have increased by a third, according to the Scottish government.
Similar rises were found by the Western Local Commissioning Group in Northern Ireland and the Swansea Bay University Health Board in Wales.
