There’s no certain way to prevent dementia from developing, but there are ways to lower your risk, said the NHS.
Eating a healthy, balanced diet should help to lower your chances of developing dementia.
It’s also important to do enough exercise. Everyone should aim to do at least 150 minutes of moderate-intensity activity every week.
There are around 850,000 people in the UK with dementia, and the condition affects one in every six people over 80 years old.
