Types of Dysarthria

Types of Dysarthria

This lesson covers flaccid and spastic dysarthria. Flaccid dysarthria is caused by LMN damage and results in breathy voice, hypernasality, and imprecise consonants. Spastic dysarthria is caused by UMN lesions and results in strained vocal quality, slow speech rate and distorted vowels. Review these key differences.

List of Questions25 questions
  1. Question 1
    • Continuous breathiness is a primary speech characteristic, related to physical attributes like weakness or atrophy.
  2. Question 2
    • Spastic dysarthria causes imprecise consonant articulation, due to hypertonia and reduced range of movement.
  3. Question 3
    • Dragging or blurring speech is a key characteristic, stemming from damage to the cerebellum.
  4. Question 4
    • Monopitch and monoloudness
  5. Question 5
    • Basal ganglia dysfunction
  6. Question 6
    • Stroke; unilateral lower face weakness
  7. Question 7
    • Phonation.
  8. Question 8
    • Flaccid dysarthria
  9. Question 9
    • Irregular articulatory breakdowns and distorted vowels
  10. Question 10
    • Speech becomes compressed or attenuated.
  11. Question 11
    • Spastic dysarthria – lesions in the upper motor neurons bilaterally. Flaccid dysarthria – lesions in the lower motor neurons.
  12. Question 12
    • Coordination; inaccuracy of movement and slowness.
  13. Question 13
    • Hypokinetic dysarthria.
  14. Question 14
    • Quick and slow forms
  15. Question 15
    • Mixed dysarthria, with variable symptoms.
  16. Question 16
    • Controlling the muscles of repsiration.
  17. Question 17
    • Spastic dysarthria
  18. Question 18
    • Ataxic dysarthria
  19. Question 19
    • Hyperkinetic dysarthria
  20. Question 20
    • Hypokinetic dysarthria
  21. Question 21
    • Trigeminal (CNV), Facial (CNVII), Glossopharyngeal (CNIX), Vagus (CNX), Accessory (CNXI), Hypoglossal (CNXII)
  22. Question 22
    • Hypokinetic
  23. Question 23
    • Palilalia is compulsively repeated phrases of accelerated rate; aprosodia is the inability to properly convey emotion in speech. Hypokinetic.
  24. Question 24
    • Hyperadduction of the vocal folds; spastic-pseudobulbar
  25. Question 25
    • Flaccid

  1. Card 1
    HintThis type of dysarthria often presents with weakness and reduced muscle tone.Memory TipThink 'floppy' muscles due to nerve damage.
  2. Card 2
    HintHow muscle strength changes over timeMemory TipFatigue at the junction signals a problem.
  3. Card 3
    HintThink of areas affecting muscle movement.Memory TipLesions ‘up high cause stiffness.
  4. Card 4
    HintAffects both sides of the brain.Memory TipA double hit leads to strained vocal quality.
  5. Card 5
    HintThis type may be due to generalized damage or bilateral lesions.Memory TipAtaxia = 'a taxi' driver who's drunk: slurred speech, incoordination.
  6. Card 6
    HintA key feature is the loss of emotional expression in speech.Memory TipHypo = 'low' movement.
  7. Card 7
    HintChorea may affect speech.Memory TipHyper = 'high' or excessive, like excess movement.
  8. Card 8
    HintOften occurs after a stroke.Memory TipUnilateral = one-sided impact resulting in weakness.
  9. Card 9
    HintThink about vocal parameters.Memory TipWeakness leads to airiness.
  10. Card 10
    HintConsider vocal and articulatory effort.Memory TipStrained speech = strained muscles.
  11. Card 11
    HintThink about 'drunken' speech.Memory TipLike 'a taxi' journey gone awry!
  12. Card 12
    HintConsider motor control problems.Memory TipExtra movements impact speech.
  13. Card 13
    HintThink about reduced expressiveness.Memory TipLow volume, low affect.
  14. Card 14
    HintInvoluntary muscle twitches.Memory TipFloppy, weak, diminished reflexes
  15. Card 15
    HintIncreased resistance to movement.Memory TipStiff muscles, exaggerated reflexes
  16. Card 16
    HintReduced facial movement.Memory TipMasked face, Parkinson's tremor.
  17. Card 17
    HintDamage to the nerve.Memory TipFlaccid follows the LMN.
  18. Card 18
    HintThink of the brain region for coordination.Memory TipAtaxia affects coordination.
  19. Card 19
    HintParkinson's affects this area.Memory TipHypo & Hyper related to BG.
  20. Card 20
    HintOne-sided damage.Memory TipUMN on one side only.
  21. Card 21
    HintThe end of the line for motor signals.Memory TipThe lower motor neuron exits.
  22. Card 22
    HintCoordination center.Memory TipCerebellum needs to coordinate.
  23. Card 23
    HintPlanning and execution.Memory TipInvoluntary control.
  24. Card 24
    HintRelated to weakened muscles.Memory TipWeak and breathy!
  25. Card 25
    HintReflects muscle stiffness.Memory TipStrained and slowwwww
