What is stroke? Know the symptoms and save a life by getting medical attention

Do you know you can have a silent stroke and not know it? You may only discover when damage has resulted.
Do you know if you get angry a lot, your blood pressure may rise and this may put you at risk for a stroke?

A stroke, is a medical condition which occurs when blood flow is prevented from reaching your brain. The cells of your brain are therefore cut off from oxygen and nutrients. If the blockage is not removed, damage could result.
According to the  National Institute of Neurological Disorders and Stroke, 8 out of every 10 strokes can be prevented.

Types of stroke
1 Ischaemic stroke
This is the most common type of stroke. This occurs when the blood vessels carrying blood to your brain get blocked by blood clots or fatty deposits from your arteries. Atrial fibrillation, which is an irregular heartbeat can cause poor blood flow resulting in blood clots which can cause a stroke if it occludes a blood vessel carrying blood to the brain.

2 Hemorrhagic stroke
The most common cause of a hemorrhagic stroke is high blood pressure (hypertension). If a hemorrhage occurs along the blood vessels in the brain, a hemorrhagic stroke will result. Those who have extremely high blood pressure can suffer from this type of stroke. Those who have high blood pressure should:
know some foods that help in lowering high blood pressure 
know what foods to avoid and 
make lifestyle changes that will generally prevent high blood pressure and other non communicable diseases.
