CDIA Final Exam 2025 Questions
and Answers
Define Dysarthria - ANSWER✔✔-A collective name for a group of speech disorders
that result from disturbances in muscular control over the speech mechanism (due to
damage of the CNS or PNS).
What is Flaccid Dysarthria? - ANSWER✔✔-Caused by bulbar palsy (multiple cranial
nerve damage that can be caused by lower motor neuron lesions)
Salient features are:
1.) Weakness of muscle contraction & hypotonia
2.) This is the only motor disorder in which a rapid breakdown of speech can occur after
a short period of continuous speaking.
Distinguishing Features:
1.) Hypernasality (often w nasal emission of air)
2.) Breathiness (continuous during phonation)
3.) Audible inspiration/stridor on inhalation
4.) Short phrases
Spastic Dysarthria - ANSWER✔✔-Found in Pseudobulbar Palsy (bilateral spastic
paralysis affects bulbar musculature, most commonly caused by strokes & head
trauma.); pyramidal system and portion of extrapyramidal.

, Upper motor neuron lesions cause spastic, stiff muscles, sluggish movement with
limited range, and weakness.
Differentiating Features:
1.) Strained-strangled voice quality
2.) Slow speech rate
3.) Slow and regular AMRs
Hypokinetic Dysarthria - ANSWER✔✔-JOE BIDEN; Associated with Parkinsonism;
Extrapyramidal system; caused by damage to basal ganglia & cortex
Characteristics:
1.) Slow, limited range
2.) Immobility and paucity
3.) Rigidity and loss of automaticity
4.) Rest tremor
Important Features:
1.) Marked limitations in range of motion
2.) Slow and lack of vigor for individualized movements
3.) Hesitations and false starts
4.) Slow, repetitive movements at times, and at other times, very fast & limited range
5.) ONLY dysarthria in which rapid rate can occur, and in which repeated phonemes
and palilalia are often found.
