Abstract

A 53-year-old woman with bilateral striatopallidodentate calcinosis (BSPDC) was referred for motor speech examination, and high-quality acoustic recordings were obtained. Three speech-language pathologists experienced in auditory-perceptual assessment of speakers with dysarthria scored 47 auditory-perceptual speech features using a 5-point equal- Appearing interval scale. Results of consensus agreement found speech to be characterized by breathy dysphonia, hypemasality, imprecise consonants, irregular articulatory breakdowns, slow rate, short phrases, and excess and equal stress. Speech signs appeared most consistent with a moderate mixed ataxic-hypokinetic dysarthria. The ataxic component predominated and was distinguished by the speech features of excess and equal stress and irregular articulatory breakdowns. Distinctive speech features of hypokinetic dysarthria included monopitch, breathy phonation, reduced loudness, and variable rate. To our knowledge, this is the first comprehensive report of the dysarthria encountered in BSPDC and can serve as a foundation for future research into dysarthria in this condition.

Professor of Neurology

I am a Movement Disorders Neurologist and see patients at the Morreene Rd Clinic and at the Durham VA Medical Center.
Among the types of movement disorders patients that I see in clinic are individuals who have Parkinson's disease, Essential Tremor, tics, chorea, dystonia, Huntington's disease, tardive movement disorders and Wilson's disease. I use botulinum toxin injections to treat selected patients afflicted with dystonia, tremors, and tics. I manage patients who have undergone deep brain stimulation (DBS) for the treatment of Parkinson's disease, Essential Tremor,and dystonia. In addition to managing patients who have movement disorders, I participate in a variety of clinical trials focussed on improving the management and treatment of Parkinson's disease, Huntington's disease, and dystonia.

Key words: movement disorders, Parkinson's disease, tremors, tics, chorea, dystonia, botulinum toxin injections.
