Stroke: An Assault on the Brain

1. Explain what happens to the brain when a stroke occurs.

   -The blood suply into the brain gets stopped, so the brain has no oxygen and the brain cells start to die.The body enlarges the arteries near that area in order to restore the blood and oxigen supply.
If thiss doesn't happen permanent brain damage or death will occur.

2. Briefly explain the differences between the three different types of strokes.

   -Emnolic: A blood clot forms in body and breaks off, the broken off piece travels to brain vessels until these are too small to let the piece pass. The clot brakes the vessel and causes an emnolic stroke.
  
 -Thrombotic: blood flow is impaired because of a blockage to one or more of the arteries supplying blood to the brain. The process leading to this blockage is known as thrombosis. 
  
 -Hemorrhagic: A bloos vessel ruptures and bleeds into the brain

3. Identify some of the most common risk factors - in other words, who is most likely to have a stroke?
  
 -People with high blood preasure
   -Smokers
   - People with diabetes
   -Obese people
   -People with high cholesterol rates 

4. What disabilities can result from a stroke?
  
  -Altough it is a brain dissease, the whole body can be affected by it. A possible result could be Hemiplegia (paralysis on one side of the body) or brain damage. The person may have damage in the motor cortex, frontal lobes and also lower parts of the brain can be affected.

5. What is brain plasticity and what does it mean in terms of recovering from a stroke?

  

 -The ability of the brain to change, grow or remap itself. It means, that a given function of a specific part of the brain can move to another part.

Stroke can cause damage to parts of the brain responsible for thinking, learning, awareness, judgement, and problem solving.

And the brain plasticity can cause this abilities to shift into another area, after the original location part has been damaged.
