Ms. Lаssiter, а 35-yeаr-оld wоman presented with a 2-year histоry of gradual mental deterioration, reduced ability to concentrate, and hand-writing difficulty. She complained of speech difficulty. Neurologic evaluation identified involuntary movements and balance difficulty, generalized motor impersistence, and mild cogwheel rigidity. Neuropsychological assessment confirmed the presence of significant cognitive limitations. MRI showed an abnormality in the right putamen that could represent iron deposition and mild generalized atrophy. During the speech examination rapid, unsustained, choreiform movements of the lower face, jaw, and tongue were present at rest. Involuntary tongue clicking was noted. She had difficulty maintaining a protruded tongue, open mouth, and lip retraction due to both motor impersistence and involuntary movements. Speech was characterized by an accelerated rate, imprecise articulation with irregular articulatory breakdowns, dysprosody, and variable rate. Vowel prolongation was characterized by low-amplitude tremor. Speech AMRs were irregular. Pitch and loudness variability was reduced, but pitch and loudness occasionally varied inappropriately.

A 49-yeаr-оld wоmаn wаs referred tо her internist because of a 2-month history of speech difficulty. Her family stated her problems were in response to a high-level of stress. The patient described her speech as "nasal" and reported recent choking on foods and liquids. She stated that food occasionally squirreled in her cheeks and she needed to use a finger to remove the food. Additionally, she said she gagged with brushing her teeth. The patient reported "crying a lot" even when she was not sad. Oral mechanism exam revealed bilateral lower face and tongue weakness and reduced lateral tongue AMRs. Her cough and glottal coup were weak. A sucking reflex was present. Her contextual speech was characterized by a groaning, strained voice quality, reduced loudness, hypernasality, imprecise and weak pressure consonants, reduced rate, short phrases, and monopitch and monoloudness. Speech AMRs were slow but regular. Vowel prolongation was mildly strained and breathy. What type of dysarthria do you suspect?
