Neuropsych B - Quiz 1

  1. Step one in neuro assessment
    look for psycho-social explanations (depression, anxiety)
  2. Step two in neuro assessment
    Asses time frame, acuity, family history and change  (recent or long standing)
  3. Step three in neuro assessment
    assess for medical involvement, especially sleep, diet, exercise, respiratory, circulatory, meds, and endocrine
  4. Step four is neuro assessment
    hypothesize most obvious explanation and continue to explore
  5. most common type of neuro assessment?
    trauma, followed by vascular
  6. Three types of TBI
    • Mild - receiving a lot of attention b/c of sports
    • closed - the most common form 
    • open - the most dangerous
  7. Effects of TBI
    • Tissue loss
    • tissue swelling or edema 
    • epilepsy
    • often leads to interpersonal problems 
    • often undetected 
    • often first seen as emotional changes
  8. Most common contributor to mTBI?
    MVA
  9. Mechanism of mTBI
    • concussion
    • acceleration/deceleration 
    • shearing/diffuse axonal injury 
    • secondary swelling
    • metabolic change
  10. Second impact syndrome
    • prior concussion followed by another impact
    • most common in athletes
  11. Diffuse Axonal Injury
    • high speed injury with stretching or shearing of brain tissue 
    • cerebral swelling and elevations in intracranial pressure, coma likely
  12. mTBI criteria
    • gasgow coma scale > 12
    • loss of consciousness < 20 min
    • hospitalization < 48 hours 
    • no obvious structural damage
  13. penetrating injuries
    • most problematic because of infection 
    • brain does not have strong infection defense 
    • fever can reach 110 degrees
  14. Mechanisms of injury
    • rotational acceleration 
    • linear acceleration 
    • carotid injuries (circle of willis)
    • deceleration on impact
  15. Cerebrovascular accident characteristics
    • caused by disease, life-style, and trauma
    • very common and often undetected
    • manifestation depends on location and degree
    • very slow and hard to recover from
  16. Cerebrovascular accident - embolic
    • sudden blockage of a vessel by some blood borne 
    • "cork"
    • usually occur w/o warning
    • associated with poor cardiovascular health 
    • onset of cognitive signs very rapid and obvious
  17. Cerebrovascular accident - thrombotic
    • gradual blockage of a vessel by plaque or inflammation
    • develop over long period of restricted blood flow 
    • associated with high cholesterol 
    • often manifest at periods of low blood pressure
    • can produce transient ischemic attacks (TIA) that serve as warnings
  18. Cerebrovascular accident - aneurysm
    • a ballooning of a weakened vessel
    • frequently occur in chronically hypertensive people
    • sudden and usually intensely painful onset
  19. Cerebrovascular accident - hemorrhagic
    • a bleed due to a puncture or rupture of a vessel
    • become more common with aging 
    • blood on brain = extremely dangerous 
    • seizures/convulsions often indicate bleed
  20. Cerebrovascular accident - arteriovenous malformation (AVM)
    • an abnormal connection between an artery and a vein
    • inefficient and often leaky these can cause gradual damage to cortical surfaces 
    • prone to rupture
  21. Warning signs of a Cerebrovascular accident
    • sudden numbness or weakness of face, arm, or leg
    • sudden confusion, trouble speaking or understanding speech 
    • sudden trouble seeing in one or both eyes
    • sudden trouble walking, dizziness, loss of balance or coordination 
    • sudden, severe headache
  22. What kind of pathology does a transient ischemic attack herald?
    Thrombotic CVA
  23. Migrane headaches can sometimes be confused with?
    CVA
  24. Why to Dr's look at the retina after a TBI?
    to look for a bulging optic disk
  25. The mantra of MSE
    Results are valid and representative of the clients cognitive functioning
  26. After a shearing injury what causes confusion about the patients initial intactness?
    some axons recover and others die off.  takes about 2 weeks
  27. What accounts for confusions when a patient shows signs of damage to the opposite side of their injury?
    expecting deficits at coup, not the contre coup
  28. what type of CVA is heralded by temporary, stroke like symptoms?
    thrombus
  29. what type of tumor would you want?
    slow-growing displacing tumor
  30. most likely cause of an aneurysm?
    hypertension
