Stroke

A stroke or a brain illness occurs when a blood clot blocks a blood vessel or when a blood vessel bursts, preventing blood flow to an area of the brain.

Types of Stroke

 An ischemic stroke happens when the blood vessel is prevented and it is the most prevalent type of stroke. A hemorrhagic stroke generally occurs when a blood vessel breaks. This type of stroke is less common.

What happens to the brain cells when a stroke happens?

During a stroke the blood flow is disrupted and the brain needs oxygen to survive. Due to lack of oxygen  the cells in the part of the brain that were receiving oxygenated blood can now die.  These cells normally die within minutes to a few hours after the stroke starts. When cells die, chemicals are released which further cause more cells to die. This is why there is a small window of possibility for the treatment of ischemic stroke.

Stroke symptoms

  • Unexpected numbness or weakness of face, arm or leg, especially on one side of the body
  • Sudden confusion, trouble speaking or understanding
  • Unexpected trouble seeing in one or both eyes
  • Unexpected trouble walking, dizziness, loss of balance or coordination
  • Immediate severe headache with no known cause
  • Nausea and vomiting
  • Loss of consciousness

Stroke prevention

 80% of strokes can be restricted by discussing modifiable risk factors. When an individual has a stroke, their risk of having another stroke is enhanced. When a person is treated for a stroke, vaccinations and suggestions are given to limit further strokes.

You can Decrease the risk of strokes by

  • Knowing and treating high blood pressure
  • Understanding and treating diabetes
  • Quitting smoking
  • Recognizing and treating high cholesterol level
