  1. organic disorders
    relates to physical structures

    does not affect the neurons
  2. example of organic disorders
    • (not affect neurons)
    • cleft palate, polyps, nodules
  3. example of neurogenic disorders
    aphasia, dementia, disarthria
  4. neurogenic disorders
    relates to the neurologic structures

    can often have physical problems, but does affect neurons
  5. right hemisphere is responsible for:
    music, reading, abstract thinking
  6. left hemisphere is responsible for:
    language
  7. motor strip area
    brocca's area
  8. language disorders are seen with damage to what area of brain?
    wernikie's area
  9. how do the 2 hemispheres differ in completing a task (overall)
    they differ in the type of processing needed to complete the task
  10. relationship between education and lateral processing
    • less education--less lateral processing
    • more education--more lateral processing
  11. left hemisphere functions
    • verbal
    • calculation
    • linguistic
    • analytic
    • sequential/linear
    • logical
  12. right hemisphere functions
    • non-verbal
    • music
    • spatial
    • wholistic/synthetic
    • parallel
    • intuitive
  13. the 2 kinds of CVA (cerebrovascular accident/ stroke)
    ischemic, hemorrhagic
  14. lack of oxygen in CVAs cause:
    tissue damage
  15. what percentage of strokes/CVAs are ischemic?
    75%
  16. the two types of ischemic CVAs
    thrombotic and embolic

    describe how the blood flow is blocked
  17. most common type of CVA
    thrombosis
  18. tia: transient asthemic attack
    warning signs of a stroke. symptoms for up to 24 hours, longer is considered a stroke
  19. tia: transient asthemic attack results from:
    thrombosis
  20. artery that supplies blood the the brain
    internal carotid artery
  21. artery that supplies blood to the face
    external carotid artery
  22. common site for thrombosis
    the bifurcation of the common carotid artery-at the level of the thyroid cartilage, becoming internal and external carotid arteries
  23. circle of willis
    provides blood to the cortex and subcortex at the base of the brain
  24. what artery feeds most of the lateral surface of the brain?
    middle cerebral artery
  25. stroke in the middle cerebral artery affects:
    language
  26. what determines the severity of a stroke
    the size and placement of the clot
  27. artery that supplies most of the medial surface
    anterior corroded artery
  28. supplies blood to the posterior and inferior surface
    posterior corroded artery
  29. what are water shed areas?
    • areas around the cortex where blood flows from 2 different arteries.
    • somewhat immude to blockages
  30. hemorrhage causes what percentage of CVAs/strokes?
    25%
  31. in an hemorrhage cva, what causes the damage?
    the hemorrhage pushing on the brain tissue because of the blood bursting and filling the area of the brain
  32. hemorrhage can be associated with what 3 things that help cause?
    trauma, aneurysm or hypertension.
  33. organic disorders can be _____ or ______
    developmental or acquired
  34. acquired is considered what time frame?
    after 3 years of age
