Stroke

A stroke is a “brain attack”. It occurs when blood flow to an area of the brain is cut off. When this happens, brain cells are deprived of oxygen and begin to die. When brain cells die during a stroke, functions controlled by that area of the brain such as memory and muscle control are lost. How a person is affected by a stroke depends on where the stroke occurs in the brain and how much the brain is damaged. There are two types of stroke called hemorrhagic and ischemic.  There are also Transient Ischemic Attacks (TIAs) that mimic stroke-like symptoms:

  • Hemorrhagic Stroke: occurs when a brain aneurysm bursts or a weakened blood vessel leaks
  • Ischemic Stroke: occurs when a blood vessel carrying blood to the brain is blocked by a blood clot
  • Transient Ischemic Attack: occurs when blood flow to part of the brain stops for a short period of time, it can mimic stroke-like symptoms. These appear and last less than 24 hours before disappearing. These are often warning symptoms of a stroke and need medical attention.
