TL;DR: Friedreich's ataxia dysarthria has a distinctive phonetic profile and contains subgroups of different severity, which should be considered when developing targets for therapy intervention.
Abstract: Background: Friedreich's ataxia is one of the most common hereditary disorders of the nervous system. Dysarthria is a pervasive symptom of Friedreich's ataxia, yet the clinical presentation of speech symptoms remains poorly understood, leaving clinicians without the evidence required to develop therapy interventions.Aims: The research reported herein had three aims: the first was to document the severity of the intelligibility deficit associated with Friedreich's ataxia dysarthria; the second was to document the phonetic profile of the intelligibility deficit; and the third was to use the results of the phonetic profile to estimate the motor control mechanisms and neurological substrates implicated in Friedreich's ataxia dysarthria.Methods & Procedures: Eleven adult males with Friedreich's ataxia were recruited. Intelligibility was assessed using a single‐word multiple‐choice task completed by ten listeners.Outcomes & Results: Intelligibility severity ratings ranged from mild to severe. The majority of su...

TL;DR: Initial estimates of the prevalence of each of four types of motor speech disorders in children with idiopathic Speech Delay (SD) were obtained and findings are interpreted to indicate a substantial prevalence of motor Speech Disorder in children in the USA.

TL;DR: In a review of 55 cases of myotonic dystrophy in childhood, 43 were found to be mentally retarded and those with the most severe and earliest physical signs were the most seriously affected intellectually.

TL;DR: The aim of this study was to characterize the speech errors made by Cantonese-speaking adults with dysarthria associated with cerebral palsy, using a perceptual-phonetic analysis.
Abstract: The aim of this study was to characterize the speech errors made by Cantonese-speaking adults with dysarthria associated with cerebral palsy, using a perceptual-phonetic analysis. The subjects were 22 adult Cantonese speakers with cerebral palsy. Fifteen subjects had spastic-type cerebral palsy, five had athetoid-type and two mixed-type. Single words were transcribed phonetically and analysed by speech part for accuracy and error patterns. There were no significant differences in accuracy for type of cerebral palsy, gender or age. Speakers with athetosis had a significantly higher relative occurrence of diphthong reduction. The majority of error patterns could be explained by the neurological damage of cerebral palsy. However, several patterns were attributed to unique features of the Cantonese phonological system. Physiological explanations and language-specific contributions to speech disorder in this group of speakers were discussed.

TL;DR: It is indicated that dysarthria and/or language impairment occurs in some cases subsequent to surgical removal of posterior fossa tumours in children aged between 6 and 16 years.
Abstract: Six children aged between 6 and 16 years who had undergone surgery for the removal of a posterior fossa tumour were assessed at least one year post-operatively to determine the incidence and severity of any associated speech or language deficits. Five males and one female were included in the sample. The subjects were administered a battery of speech/language assessments including: a language screening test, an articulation test, a dysarthria assessment and a perceptual speech analysis. The results indicated that dysarthria and/or language impairment occurs in some cases subsequent to surgical removal of posterior fossa tumours. The occurrence of muteness immediately post-surgery would appear to indicate a poor prognosis for speech abilities. A possible link between the occurrence of long term language disabilities in these children and post-surgical radiotherapy is documented.
