Warning as two new risk factors for dementia discovered

Dementia is a syndrome, or a group of associated symptoms, linked to the progressive decline of the brain. This can cause memory problems, behavioural changes and even mobility issues. Due to the fact it is more common in people over the age of 65, it is often thought of as a condition that can happen as you get older.

Although it is true that the risk of dementia increases as you age, this is not the only pre-determining factor. Research has shown that 40 per cent of dementia cases could be prevented by making certain lifestyle changes.

These have previously been noted as factors such as limiting alcohol intake, exercising regularly and maintaining a healthy weight. However, a new study has linked two more factors to increased risk of dementia - with millions of Britons vulnerable.

Scientists have now identified untreated vision loss and high cholesterol as risk factors for dementia. The updated Lancet Commission on dementia prevention, intervention, and care also found that nearly half of cases of dementia worldwide may be attributed to such risk factors.

Study findings are due to be presented at the Alzheimer’s Association International Conference in Philadelphia on July 31. Fiona Carragher, chief policy and research officer at the Alzheimer’s Society - which part-funded the study - said: “Dementia is the UK’s biggest killer and a global crisis affecting more than 55 million people, but it’s never too early or too late to reduce your dementia risk.

“This Lancet Commission study, part-funded by Alzheimer’s Society, identifies two new risk factors for developing dementia: untreated vision loss and high low-density lipoprotein cholesterol [‘bad’ cholesterol]. It also suggests that nearly half of dementia cases across
