2. The areas of the brain that do not get enough oxygen are immediately affected.
3. If no blood to brain stem - cannot breath and no heart rate
4. If no blood to cerebellum - no coordination balance
5. If no blood to cerebrum - cannot talk and no control motor function
6. A person might go limp on one side when attacked by stroke.

1. Ischemic strokes
  • cause : blood clot ( cerebral thrombosis or a cerebral embolism)
  • cerebral thrombosis is more common- usually the result of fatty plaque build in arteries.

  • dying cells may release glutamate
2. hemorrhagic stroke
  • cause : bleeding in the brain
  • in cerebral hemorrhage, blood go to surrounding tissues- due to aneurysm or head injury
  • In a subarachnoid hemorrhage, the bleeding occurs between the brain and the skull- increase intracranial pressure
