  1. Left hemisphere
    usually dominant, controls language acquisition, math and reasoning
  2. Right hemisphere
    artistic and emotional
  3. Cerebrum
    left control right, right controls left; initiation of movement, endocrine, autonomic functions
  4. Cerebellum
    right controls right; uses info from cerebrum, muscles, joints and inner ear to coordinate movement, balance and posture
  5. Circle of Willis
    Internal carotid and vertebrobasilar arteries
  6. Stroke-third leading cause of death and leading cause of disability
  7. Risk factors
    AFA males, people 51-74, family history
  8. Common factors leading to stroke
    Hypertension, cardiac disease, DM
  9. TIA
    temporary neurologic deficit caused by impairment of cerebral blood flow; blood flow occluded by spasms, fragments of plaque, or blood clots
  10. Stroke
    abrupt impairment of brain functioning resulting in a set of neurologic signs and symptoms that are caused by impaired blood flow to the brain and last for more than 24 hours
  11. Hemorrhagic
    sudden onset, blood vessel in brain ruptures
  12. Intracerebral stroke
    bleed in the cerebrum and usually associated with trauma, uncontrolled HTN and aneurysms
  13. Ischemic
    Obstruction of blood vessel by plaque, blood clot, or both
  14. Embolic
    originate from heart and circulate to cerebral vasculature; associated with AF, valvular heart disease and thrombi in left ventricle
  15. Thrombotic
    caused by plaque in blood vessels in the brain; results in ischemia and infarction
  16. Hemorrhagic s/s
    �worst headache ever,� LOC, vomiting and seizures
  17. Embolic s/s
    one sided weakness, numbness, visual problems, memory lapses, headache, dysphagia
  18. Left sided damage
    right side paralysis, aphasia, slow cautious behavior, memory deficit, aware of deficits
  19. Right sided damage
    left side paralysis, spatial perceptual deficits, quick and impulsive behavior, memory deficits, impaired judgment, short attention span, left side neglect
  20. Dysarthria
    inability to speak clearly due to control of muscles used in speech
  21. Dyspraxia
    partial inability to initiate coordinated voluntary motor acts (inability to perform a previously learned action)
  22. Hemiplegia
    first flaccid and then spastic
  23. Initial diagnostic test for a stroke
    CT to determine ischemic or hemorrhagic
  24. Lumbar puncture is not done is ICP is suspected
  25. Interventions directed at minimizing complications of a stroke
    hypertension, oxygenation, hyperthermia and hyperglycemia
  26. What does nimodipine do
    calcium channel blocker decreases spasms in cerebral vessels after bleed
  27. Completed stroke
    when neurologic deficits do not change for two to three days
  28. Receptive aphasia
    difficulty understanding spoken or written words
  29. Expressive aphasia
    difficulty speaking and writing
  30. Fluent aphasia
    sounds normal but makes little sense
  31. Nonfluent aphasia
    difficulty initiating speech
  32. Global aphasia
    person has almost no ability to communicate
  33. Homonymous hemianopsia
    perceptual problem that involves loss of one side of the field of vision
  34. What may be given in patient with acute strokes to dissolve clots
  35. NIH stroke scale
    lower is better
  36. Ptosis
    drooping upper eyelid
  37. Used to treat cerebral edema
  38. Used to treat hemorrhagic stroke by dilating and preventing spasms min cerebral blood vessels
  39. Used to reduce ICP by reducing cerebral inflammation
  40. Used to prevent strokes caused by thrombi
  41. Used to dissolve clots that cause acute ischemic stroke
  42. Used to destroy thombi
