Predicting who’s at risk
A stroke happens when the blood supply to part of the brain is cut off. It is often caused by a blockage in a blood vessel or a burst blood vessel.
Currently, we know that some people have a higher risk of stroke. For example, people from Black or South Asian backgrounds, or anyone with a family history of stroke.
Heart disease and high blood pressure also raise the risk of stroke. As do lifestyle factors, such as smoking, drinking, and a lack of exercise.
There’s much more to learn. “We know that genes play a role in stroke risk, but we don’t have the full picture,” says Dr Iain Turnbull, a practising NHS GP and Our Future Health’s Deputy Chief Medical Officer.
“With Our Future Health’s data, researchers can conduct studies to find out which genes are linked to stroke. And they can see how these genes interact with other risk factors.”
