A third of all dementia cases are caused by lifestyle factors

Currently, in the UK there are more than 850,000 people living with dementia and this number is expected to rise to more than a million by 2025.

Scientists believe that a third of all dementia cases are caused by factors that are under an individual’s control, such as leading a healthy lifestyle.

However, according to Alzheimer’s Research UK, only one in three adults believe it is possible to reduce their risk of getting the disease.

The main factors that can influence the likelihood of developing dementia include medical risks such as, genetics, depression, diabetes and high blood pressure. Other factors include smoking and heavy drinking, while high levels of participation in exercise have been known to protect against the disease.

Figures indicated 85 per cent of people said they are willing to take a test to see whether they were in the early stages of developing dementia.

The survey also revealed that 49 per cent of people did not know that dementia was a cause of death, and more than a fifth incorrectly said it was simply part of getting older.

Hilary Evans, the Chief Executive of Alzheimer’s Research UK, said: “Dementia is the UK’s biggest killer but only half of people recognise it even causes death.

“Making breakthroughs in public understanding has the potential to empower more people to take steps to maintain their own brain health, to seek a diagnosis and to support research that has the power to transform lives.”

Care Minister, Caroline Dinenage said: “Prevention is becoming an increasingly vital tool in tackling dementia.

“By spreading the word on prevention, we can help fulfil the Government’s ambition to make England the world leader in dementia care, research and awareness.”
