What are the chances of having a stroke?
A stroke is a brain attack. It’s damage to part of the brain usually from a blood clot blocking an artery, but can also from bleeding (cerebral haemorrhage).
GPs are increasingly assessing a person’s risk of stroke in the next five or ten years based on factors such as age, smoking, high blood pressure and cholesterol, past history of a heart attack or minor stroke and diabetes.
If the five or ten year risk is high (say more than 10 or 15 per cent) then the doctor will usually recommend treatment and risk factor reduction.
But that’s just about people at risk over the next few years. What about your total lifetime chances of having a stroke?
That’s what researchers have just calculated globally and the results were shocking.
On average one in four people will have a stroke sometime in their lives. If you live in Eastern Europe it can be as high as one in three people. In Australia it’s one in five people – still a high number.
Does this mean we all need to be on medications for life?
No, say the researchers unless you’re at very high risk but it does mean from early on in life making sure your blood pressure is normal, you don’t smoke, you exercise, don’t consume more than the recommended level of alcohol, keep salt intake low, control your weight and try to prevent diabetes.
It’s a bit of a lottery but the dice are loaded against people who have poor lifestyles.

Stroke: signs, symptoms and treatment
A stroke occurs when a part of the brain is damaged or destroyed because it is deprived of blood, and therefore oxygen. Ischaemic stroke is the most common.
TIA: transient ischaemic attack
A TIA (transient ischaemic attack), also called a mini-stroke or temporary stroke, is when there is a temporary block in the blood supply to a part of the brain.
Vascular dementia is a general term that describes problems with reasoning, planning, judgement, memory and other thinking skills.
Metabolic syndrome is a condition that increases your risk of heart disease, stroke and diabetes. Lifestyle changes are the first step in its treatment.
High blood cholesterol can increase your risk of cardiovascular disease. By eating less saturated fat you can help to lower your LDL or 'bad' cholesterol.
