Question 21

A 68 year old man presented with a 5 year history of difficulty getting into and out of chairs, stiffness during walking, and difficulty turning in bed. He had voice and handwriting difficulty. He presented with neck rigidity and diminished arm swing. Facial expression was masked. He reported he was uncertain if “words would come out.” His spouse reported he was quieter and slower in the evening or following extended periods of speaking. His jaw, lips and tongue were mildly tremulous during sustained postures. Infrequent rapid repetitions, prolongations of initial phonemes, nasal emission (but did not sound hypernasal) were observed during the speech evaluation. Speech AMRs were normal and prolonged “ah” was breathy-hoarse. What type of dysarthria did this gentlemen have?

Answer 21

hypokinetic

Question 22

A 73 year old woman presented with a 10 year history of voice difficulty that was present upon awakening one day. The problem progressed for a while by the patient had been stable for several years. Neurologic evaluation identified a head tremor, postural upper extremity tremor, and “spastic speech.” The speech evaluation noted her speech was characterized by a tremor that consistently interrupted her voice and slowed her speech rate. Prolonged “ah” contained consistent, somewhat irregular, and strained voice interruptions were noted. Tremor fluctuations were not apparent during prolongation of voiceless fricatives. What type of dysarthria did this patient have?

Answer 22

hyperkinetic

Question 23

Slurred speech and “drunken” sounding speech is one of the hallmark complaints of individuals with which type of dysarthria?

Answer 23

ataxic

Question 24

What is the specific neuromuscular basis (or main problem) associated with hyperkinetic dysarthria?

Answer 24

involuntary movements

Question 25

A 63 year old female was hospitalized for evaluation and treatment of cardiovascular problems. Three weeks before admission, she suddenly developed speech and gait difficulty. She had no difficulties with language, chewing, or swallowing. A CT scan of the head identified a 2-cm area of low attenuation in the right cerebellar hemisphere consistent with a stroke. The speech pathologist was consulted. Speech-language evaluation results noted: normal oral mechanism exam; speech difficulties included irregular articulatory breakdowns, irregular speech AMRs, and unsteady vowel prolongation. The SLP reported intelligibility was normal. With what motor speech disorder would you diagnose her?

Answer 25

Ataxic
