Causes of Stroke
There are are two main types of Stroke - Ischaemin Strokes and Haemorhagic Strokes. Which effect in different ways and can have different causes.
Ischaemin Strokes are the moist common type of Stroke. They occur when a blood clot blocks the flow of blood and oxygen to the brain.
These blood clots typically form in areas where the arteries have been narrowed or blocked over time by fatty deposits know as plaques. This process is know as atherosclerosis.
As you get older, the arteries naturaly narrow, but certain things can dangerously accelerate the process. These include:
-High blood pressure#
-An excessive alcohol intake
Another possible cause od Ischaemic Stroke is a type of irregular heartbeat called atrial fibrillation, which can cause blood clots in the heart that break up and escape from the heart and become lodged in the blood vessels supplying the brain.
Atrial fibrillation can have a number of different causes, including lung disease, heart valve disease, excessive alcohol intake, coronary heart disease, and an overactive thyroid gland.
Haemorrhagic Strokes are less common than ischaemic Strokes. They occur when a blood vessel within the skull bursts and bleed into and around the brain.
The main cause of heamorrhagic Stroke is high blood pressure, which can weaken the arteries in the brain and make them prone to split or rupture.
Things that increase the risk of high blood pressure incluide:
-Being overweight or obese
-Drinking exessive amounts of alcohol
-A lack of exercise
-Stress, which may cause a temporary rise in blood preessure
Haemorrhagic Strokes can also occur as the result of the rupture of a balloon-like expansion of a blood vessel and badly-formed blood vessels in the brain.
Can I reduce my risk?
It's not possible to completely prevent Strokes because some things that increase your risk of the condition cannot be changed. However, in most casesit is possible to significantly reduce your risk of having a Stroke by making life style chamges.
