We normally think of blood clotting as a good thing as blood needs to clot for a wound to heal. However, when a blood clot actually blocks an artery or cuts off blood flow, then a clot is dangerous.
This stroke occurs when a blood clot forms somewhere in the body (usually the heart) and travels through the blood stream to the brain. It gets stuck in the brain and stops blood from getting through.
When cholesterol laden plaque builds up on the inner wall of an artery, it can makes the passage so narrow that it can block the blood supply from getting through.
A Bleed in the Brain
There can be a break in the wall of a blood vessel on the brain, leading to a leak which stops the delivery of oxygen and nutrients.
High blood pressure is a common cause of this haemorrhagic stroke. An aneurysm is a weak or thin spot on a blood vessel wall and usually occur at birth; but are not usually detectable until they break, often many years later.
Tips and Hints
A stroke occurs wether from a blood clot or plaque that blocks an artery in the brain; or a blood vessel in the brain ruptures, causing a bleed/ It is essential that you have regular cholesterol and blood pressure check-ups. Treating these conditions is much better than trying to treat a stroke.
The terminology may be difficult to remember or pronounce, but the description of just what happens to the brain to cause a stroke, is easy to understand as the word description is accompanied together with a diagram.
