A stroke happens when a grume blocks blood flow to the brain. This causes brain tissue to become damaged or die.
A stroke, sometimes called a brain attack, occurs when something blocks blood supply to a part of the brain or when a vessel within the brain bursts. In either case, parts of the brain become damaged or die. A stroke can cause lasting brain damage, long-term disability, or maybe death.
To understand stroke, it helps to know the brain. The brain controls our movements, stores our memories, and is that the source of our thoughts, emotions, and language. The brain also controls many functions of the body,
like breathing and digestion.
To work properly, your brain needs oxygen. Although your brain makes up only 2% of your weight , it uses 20% of the oxygen you breathe. Your arteries deliver oxygen-rich blood to all or any parts of your brain.
What Happens During a Stroke
If something happens to dam the flow of blood, brain cells start to die within minutes because they can’t get oxygen. This causes a stroke.
There are two sorts of stroke:
Ø An ischaemic stroke occurs when blood clots or other particles block the blood vessels to the brain. Fatty deposits called plaque also can cause blockages by build up within the blood vessels.
Ø A haemorrhagic stroke occurs when a vessel bursts within the brain. Blood builds up and damages surrounding brain tissue.
Both sorts of stroke damage brain cells. Symptoms of that damage start to point out within the parts of the body controlled by those brain cells.
