CSD 444 Quiz Questions and Answers Fully Solved Latest Version 2025-2026
Motor Speech Disorder - Answers Disorders of speech production resulting from neurologic
impairment affecting the motor programming (apraxia of speech) or neuromuscular execution
of speech (dysarthria)
What is a motor speech disorder? - Answers May co-occur with other language impairments
e.g., Broca's aphasia with apraxia
Other oral movements (besides speech) may be impaired, including chewing and smiling
Causes of motor speech disorders - Answers CVA
Traumatic brain injury
Brain tumors (ALL DEPENDS ON LOCATION)
Degenerative diseases: amyotrophic lateral sclerosis (ALS), Parkinson's disease, Huntington's
disease etc.
Large percentage of acquired neurogenic communication disorders are motor speech disorders
(_______%) - Answers 50%
Apraxia - Answers A speech disorder which results from an impairment in motor programming
(planning and organization of speech movements) —has to have damage to the brain
prior to execution of speech movements
Dysarthria - Answers A speech disorder resulting from weakness, paralysis, or incoordination of
the muscles for speech production
-Actual execution of speech movements
-Muscles may be weak
What are the three types of apraxia? - Answers 1. Limb apraxia
2. Oral apraxia.
3. Apraxia of speech.(verbal apraxia)
Limb Apraxia - Answers Difficulty with voluntary movements of limbs.
Reflexive movements are ok.
Won't effect your speech
Oral Apraxia - Answers Difficulty with voluntary movements of the mouth.
, Ex: if you tell someone to stick out their tongue, they may just open their mouth or smile but if
you give them an ice cream on a cone they know what to do with it
Apraxia of Speech (Verbal Apraxia) - Answers Affects the initiation and execution of movements
for speech.
Core impairment in planning and/or programming speech movement sequences.
Acquired apraxia of speech - Answers Result of stroke or brain damage to specific area in
frontal lobe of brain including Broca's area or insula
Usually in adults
Often co-occur in Broca's aphasia
Childhood apraxia of speech - Answers Can be difficult to distinguish from severe articulation
disorder
It never goes away (don't grow out of it)
Common characteristics of apraxia of speech - Answers Inconsistent errors - multiple
repetitions not the same
More errors as complexity increases
More errors on nonsense words, as compared to real words
More errors with increased speech rate
May be aware of errors and try to correct(unless its wernicke's)
Restarts and repeated attempts at producing a word and repeating sounds and syllables
Articulatory groping(searching for where to place their tongue or position their lips), sometimes
with facial grimacing, starting words is especially problematic
What are the types of dysarthria - Answers Spastic
Flaccid
Ataxic
Hypokinetic
Hyperkinetic
Mixed
Hypokinetic Dysarthria - Answers Characterized by hypokinesis (decreased movement)
