Who’s at risk?
Strokes are uncommon, but certainly not rare in men in their fifties, like Andrew Marr.
While the majority of strokes occur in over-65s, around one in four strokes occur in people under the age of 65.
The main risk factor for a haemorrhagic stroke is high blood pressure as the excess pressure can weaken the arteries in the brain and make them prone to splitting or rupturing.
In turn, risk factors for high blood pressure include:
Being overweight or obese
Drinking excessive amounts of alcohol
Lack of exercise
