  • Stroke patient - Joseph Q3
    • Pathophysiology
      • Sudden impairment of cerebral circulation in one or more of the blood vessels supplying the brain
        • Interrupts oxygen supply
          • Causes damage to necrosis in brain tissue
    • 3 different types of stroke
      • Ischemic
        • Occurs as a result of an obstruction within a blood vessel supplying the brain (clot) - 87% of cases
          • Cerebral thrombosis - clot that develops at the clogged part of the vessel
          • Cerebral embolism - clot formed in another part of the body and travelled into the blood vessels of the brain
      • Hemorrhagic
        • Weakened blood vessel ruptures (bleed) most commonly from uncontrolled hypertension
          • Blood compresses the surrounding brain tissue
      • TIA (Transient  Ischemic Attack)
        • A temporary clot - often called a 'mini stroke'
          • Most last less than 5 minutes
          • Usually causes no permanant damage to the brain
    • Warning signs
      • Sudden weakness of one side of the body
      • Sudden confusion
      • Trouble speaking
      • Trouble seeing in one or both eyes
      • Trouble walking, dizziness, loss of balance or coordination
      • Sudden severe headache with no clear cause
