    abnormal acumulation of fluid in tissue
  6. anoxia
    lack of oxygen to the brain
  7. ischemic stroke
    result of a blocked artery  80%  over 3 mins which leads to death of brain tissue and swelling of brain tissue can lead to additional damage
  8. infarction
    death of brain tissue
  9. TIA
    What are the symptoms of TIA?
    • Transient ischemic attack
    • Temp closing or occlusion of an artery
