artic ataxic dysarthria
Show Answers:

  1. ataxic dysarthria is caused by damage to
    cerebellum or neural pathway that connect it to the CNS
  2. ataxic means
    widespread in-coordination, out of order
  3. speech errors primarily with ataxic
    articulation and prosodic
  4. voice quality with ataxic
    harsh, monotonous pitch and volume
  5. prosody with ataxic is
    reduced to unnatural stress
  6. speech of those with ataxic is
    • unsteady, slurred, dragging and blurred
    • likened to drunken speech
  7. cerebellum primary function
    coordinate timing and force of muscular contractions
  8. what processes sensory information from all over the body and integrates it into execution of movement
  9. the cerebellum is attached to the brainstem T or F?
  10. the cerebellum is attached to the brainstem and communicates with the rest of the CNS through neural tracts called
    cerebellar peduncles
  11. by exchanging information through the cerebellar peduncles, the cerebellum is able to
    monitor ongoing movements and comminicate with the cortex concerning planned upcoming movements
  12. the cerebellar peduncle tracts:
    inferior, middle, superior
  13. this peduncle allows the cerebellum to receive sensory info from the entire body about position of body parts. This vast amount of sensory info lets cerebellum know body positions before, during and after movement
  14. the largest peduncle
  15. this tract connects the cerebellum to the cortex
    middle peduncle
  16. this tract receives preliminary info from the cortex regarding planned movements
  17. it is thought that the _______ peduncle recieves rough preliminary motor impluses via the cotex and sends them to the cerebellum to be coordinated
  18. this peduncle is the cerebellum's main output channel to the rest of the CNS
  19. it is through this that the cerebellum sends its processed motor impulses to the motor areas of the cortex
  20. the entire corticocerebellar control circuit
    starts in the cortex, courses down thru cerebellum thru middle peduncle which exit the cerebellum thru the superior peduncle and travel back up to the cortex after passing thru thalamus 
  21. there are other tracts coursing out of the superior peduncle that connect the cerebellum to the
    extrapyramidal system
  22. the precise nature of cerebellum's influnce on speech is very clear?
    NO, unlcear
  23. probable ways the cerebellum affects speech:
    • corticocerebellar control unit
    • planned motor movements for speech are sent from cortex to cerebellum which refines and coordinates
  24. cerebellum probably coordinates speech by:
    • sensory info about the positions and conditions of the articulators
    • prior practice on what skilled target movements should be
  25. one way the cerebellum may influence speech movements is thru connections with the:
    extrapyramidal system
  26. movement deficits of timing, force, range and directions due to cerebellar damage is:
    cerebellar ataxia
  27. those with cerebellar ataxia gait:
    wide, staggering gait, looks like about to fall
  28. This degenerative disease has a late onset:

    How does one develop it?
    Autosomal Dominant cerebellar Ataxia of Late Onset

  29. what is the prognosis of Autosomal Dominant Ataxia Late Onset?
    poor, death within a few years after symptoms
  30. Idiopathic Sporadic Late Onset cerebellar Ataxia often results in:

    What is the cause?
    progrssive cerebellar ataxia, ataxic dysarthria, and balance deficits

  31. this disease can affect the spinal cord as well as the cerebellum

    how does one get it?
    Friedrich's Ataxia

  32. spinocerebellar disease
    Freidrich's Ataxia
  33. this disorder becomes evident in the 20's with few living past their 40's:

    death occurs after:
    • friedrich's ataxia
    • coma or heart failure
  34. dysarthria with friedrich's
  35. this disease results in atrophy of the middle peduncle, much of the cerebellum, and parts of the pons
    olivopontocerebellar degeneration
  36. symptoms of this are parkinsons like, muscular rigidity, and reduced range of movement
    olivopontocerebellar degeneration
  37. ___% of intracerebral hemorrhages primarily affect the cerebellum or circuits
  38. is stroke a cause of ataxic dysarthria?
  39. are toxic exposures causes of ataxic dysarthria?
    if yes, to what?
    yes, lead and mercury poisoning, acute and chronic alcohol use and other chemicals
  40. is ataxic dysarthria treatable in those with toxic exposure?
    yes, will resolve as levels go down
  41. exposure to this antiseizure drug can cause ataxia and may be irreversible
  42. some metabolic causes:
    lack of B12 or E, severe hypothyroidism, and hereditary disorders
  43. with TBI causing ataxia, is the damage usually focal or diffuse?
  44. these are especially vunerable to rapid rotational force in a TBI with high amounts of axonal stretching
    cerebellar peduncles
  45. how may a tumor affect cerebellar function?
    may grow inside or close to destroying cells and compressing tissue, or it may interfere with control units
  46. ataxic dysarthria speech quality is described as
  47. is scanning speech used to describe it?
    yes, some use this term
  48. scanning speech in ataxic is:
    slow, deliberate with each syllable with equal stress
  49. significant problem in ataxic speech
  50. most prevelent prob in ataxic
    imprecise consonants
  51. are distorted vowels a common error?
  52. defecits complex movements requiring more than one body part are called
    decomposition of movement
  53. are the artic errors always consistent?
    no, irregular breakdowns
  54. are prosodic errors prominant?
  55. prosodic errors:
    equal and excess stress, prolonged phonemes, prolonged intervals between phonemes, monopitch, monoloud, slow rate
  56. is slowness a characteristic? if so why?
    yes, probably due to hypotonia
