A stroke happens when blood supply to the brain is interrupted.
Blood is carried to the brain by blood vessels called arteries which transports oxygen and important nutrients for your brain cells.
Blood may be interrupted or stop moving through an artery, because the artery is blocked. When brain cells do not get enough oxygen or nutrients, they die.
Brain cells usually die shortly after the stroke starts.
However, some can last a few hours, if the blood supply is not cut off completely.
If the blood supply can be returned in the minutes and hours after the stroke, some of these cells may recover. If not, they will also die.
There are sometimes quite specific warning signs before a stroke.
By recognising the warning signs and taking action, you may be able to prevent a stroke or reduce its severity.
- Personality changes
- Epileptic attacks
- Lightheadedness or weakness
- Breathing problems
It is important to be able to recognize the warning signs and get medical help as quickly as possible.
