A stroke occurs when the blood supply to part of your brain is interrupted or severely reduced, depriving brain tissue of oxygen and food. Within minutes, brain cells begin to die.
There are two types of risk factors for stroke: controllable and uncontrollable. Controllable risk factors generally fall into two categories: lifestyle risk factors or medical risk factors. Lifestyle risk factors can often be changed, while medical risk factors can usually be treated. Both types can be managed best by working with a doctor, who can prescribe medications and advise on how to adopt a healthy lifestyle.
Stroke symptoms include:
SUDDEN numbness or weakness of face, arm or leg - especially on one side of the body.
SUDDEN confusion, trouble speaking or understanding.
SUDDEN trouble seeing in one or both eyes.
SUDDEN trouble walking, dizziness, loss of balance or coordination.
SUDDEN severe headache with no known cause.
Seriously disabled stroke sufferers surprised doctors by regaining movement in their hands and legs after receiving a pioneering new treatment where stem cells are injected into the brain. With intra-arterial delivery, the cells are delivered directly to the brain via the carotid artery, avoiding their becoming trapped in the lungs and liver, which occurs when stem cells have been administered intravenously
