What causes a stroke?
There are two main types of stroke, and each has different causes. The first
type, an ischaemic stroke, occurs when a blood clot blocks an artery serving
the brain, disrupting blood supply. Very often an ischaemic stroke is the
end result of a build up of cholesterol and other debris in the arteries
(atherosclerosis) over many years.
