Types
1. Ischemic
  1. blood supply to part of the brain is decreased
    1. dysfunction of brain tissue
    2. Causes:

      2. Embolism
      3. Systemic hypoperfusion
      4. Cerebral venous sinus thrombosis

        Intracranial aneurysm
        cerebral amyloid angiopathy
        cerebral arteriovenous malformation
Management
Complications
1. may occur within 72 hours of stroke
2. cerebral edema
3. Increased ICP
4. Intracerebral hemorrhage
5. Seizures
6. Speech problems
7. hemiparesis
