Ch 6 UUMN Dysarthria

  1. T/F UUMN dysarthria is caused by bilateral damage.
  2. Where would you see demonstrable weakness is a patient with UUMN dys.?
    lower face, lips, and tongue on the OPPOSITE side from the lesion.
  3. What is the primary characteristic of UUMN dysarthria?
    articulation deficits
  4. T/F UUMN dysarthria is typically severe.
    F-it is typically mild.
  5. The most consequences of UUMN damage is to the?
    muscles of the lower face and tongue
  6. Unilateral weakness of the tongue and lower face will usually result in movements that are?
    slow and have a reduced ROM and decreased fine motor control of the lips
  7. If you asked a patient with UUMN dysarthria to stick out his tongue, which dicrection would it deviate to? (toward or away from the affected side?)
  8. Why does the traditional view believe that the velum, pharynx, and larynx will be significantly affected by UUMN damage?
    because the UMNs on the unaffected side will provide sufficient innervations to both cranial nerves serving the two sides of these structures. (McKaig said this was a "good test question")
  9. T/F Any condition that causes damage to either the left or right hemisphere UMNs can cause UUMN dys.?
  10. When damage happens in the LEFT hemisphere, UUMN dys .typically occurs with?
    aphasia or apraxia of speech
  11. When damage happens in the RIGHT hemisphere, UUMN dys. typically occurs with?
    cognitive and visual deficits associated with injury to the right side of the brain.
  12. Which type of lesion (focal or diffuse) are the most common cause of UUMN dys.?
  13. What is the most common cause of UUMN dys.?
    stroke ("good test question")
  14. Where can strokes occur in the brain that would cause UUMN dys?.
    • almost anywhere that contains UMNs.
    • -cortical and subcortical areas
    • -brainstem
    • -internal capsule
    • -frontal lobe
  15. What are the 3 ways that tumors can cause UUMN dys.?
    1. compress the arteries or veins serving the UMNs and interfere with normal blood flow to and from these cells.

    2. displace and squeeze UMNs thereby compromising the function of these neurons.

    3. tumor may directly cause the destruction of UMNs as it grows which results in a degradation of the transmission of motor impulses from higher brain centers to the cranial and spinal nerves.
  16. T/F TBI is a common cause of UUMN dys.
    false (because traumatic brain injuries typically result in diffuse brain damage)
  17. Are effects of UUMN dys. considered to be mild to moderate or moderate to severe?
    mild to moderate
  18. T/F UUMN dys. is often a short-term disorder for mildly impaired patients.
  19. Why would co-occurring speech and language disorders make it difficult to diagnose UUMN dys?
    the patient's verbal output may be limited
  20. UUMN dys. is principally a disorder of?
    articulation ("good test question")
  21. What is the primary articulation deficit for patients with UUMN dys.?
    imprecise articulation
  22. T/F Mild to moderate harsh vocal quality will not be present in cases of UUMN dys.?
    false-it may be present in some cases
  23. T/F Hypernasality is present in most cases of UUMN dys.
    false, it can be present, but it is not present in a majority of cases
  24. T/F Prosody and respiration are often impaired in cases of UUMN dysarthria?
    false-they are rarely impaired ("good test question")
  25. When prosody is affected it usually shows up how?
    as a slightly slow rate of speech
