Things that can increase your chances of getting vascular dementia in later life include:
- high blood pressure (hypertension)
- an unhealthy diet
- high blood cholesterol
- lack of exercise
- being overweight or obese
- drinking too much alcohol
- atrial fibrillation – a type of irregular heartbeat (arrhythmia) – and other types of heart disease
These problems increase the risk of damage to the blood vessels in and around your brain, or cause blood clots to develop inside them.
By making healthy lifestyle changes, such as stopping smoking and exercising regularly, and treating any health conditions you have, you may be able to reduce your chances of getting vascular dementia.
This may also to help slow down or stop the progression of vascular dementia if you're diagnosed in the early stages. Find out more about treating vascular dementia.
But there are some things you cannot change that can increase your risk of vascular dementia, such as:
- your age – the risk of vascular dementia increases as you get older, with people over 65 most at risk
- your family history – your risk of problems such as strokes is higher if a close family member has had them
- your ethnicity – if you have a south Asian, African or Caribbean background, your risk of vascular dementia is higher, as related problems such as diabetes and high blood pressure are more common in these groups
In rare cases, unavoidable genetic conditions can also increase your risk of vascular dementia.
