Stroke..

on

A stroke is a medical condition in which poor blood flow to the brain results in cell death. Basically a  stroke is a “brain attack”. It can happen to anyone at any time. It occurs when blood flow to an area of brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, abilities controlled by that area of the brain such as memory and muscle control are lost.
How a person is affected by their stroke depends on where the stroke occurs in the brain and how much the brain is damaged. 
 # There are  2  types  of  stroke  :-

 • Hemorrhagic Stroke

A brain aneurysm burst or a weakened blood vessel leak is one of two types of stroke. Blood spills into or around the brain and creates swelling and pressure, damaging cells and tissue in the brain. While the least common of the two types of stroke it most often results in death.
  • Ischemic Stroke
 A blood vessel carrying blood to the brain is blocked by a blood clot . This causes blood not to reach the brain. High blood pressure is the most important risk factor for this type of stroke
