Flashcards in The Dysarthrias Deck (14):
1

What characteristics are shared between all types of dysarthria

impaired muscular control of the speech mechanism
PNS or CNS pathology

2

What creates the differences in the nature of dysarthria

the nature and the loci of the pathology

3

Name the neurological diseases that are associated with Dysarthria

Prakinson's
Wilson's
progressive supranuclear palsy,
dystonia
Huntingtons Disease
ALS
MS
Mysthenia Gravis

4

What non-progressive neurological conditions can cause Dysarthria

Stroke
Infections
TBI
surgical Trauma
CP
toxic effects of drugs and alcohol

5

Common Sites of Lesion include:

Lower Motor Neuron, unilateral or bilateral Upper motor neurons, cerebellum, and basal ganglia (extrapyramidal system)

6

Ataxic Dysarthria results from damage to the

cerebellum

7

Major Characteristics of Ataxic Dysarthria Include:

-gait disturbances
-movement disorders: over or undershooting targets, jerky movements
- articulation disorders: imprecise production of consonants
-prosody disorders
-phonatory disorders - monopitch, monoloudness, and harshness
-drunken like speech quality

8

Flaccid Dysarthria is a result of

damage to the motor units of cranial or spinal nerves that supply speech muscles

9

Neuropathology that causes Flaccid Dysarthria Includes

Mysasthenia Gravis
Botulism
vascular diseases
brainstem stroke
infections
Gullian Barre
ALS

10

Specific Cranial Nerves that may be involved in Flaccid Dysarthria Include

Trigeminal V
Facial VII
Glossopharyngeal IV
Vagus X
Hypoglossal XII

11

major characteristics of Flaccid Dysarthria Include

-Muscular Disorders: Atrophy, Weakness, Hypotonia, and Diminished Reflexes.
-Fasciculations and Fibrillation
-rapid and progressive muscle weakness with the use of a muscle and recovery with rest
-respiratory weakness in combination with cranial nerve weakness
-Phonatory Disorders: breathy voice, audible inspiration, short phrases.
-Resonance Disorders: hyper nasality, imprecise consonants, nasal emission and short phrases
-Phonatory-Prosodic Disorders: including harsh voice, monopitch and monoloudness
- Articulation Disorders are more pronounces with lesions in cranial nerve V, VII, VII

12

Hyperkinetic Dysarthria occurs after damage to the

Basal Ganglia (extrapyramidal system)

13

This Dysarthria is associated with involuntary movements, and variable muscle tone. Prosodic disturbances are dominant.

Hyperkinetic Dysarthria

14

Causes of Hyperkinetic Dysarthria

degenerative, vascular, traumatic, infectious, neoplastic and metabolic factors may be involved.
Huntington Disease
