Background: The speech disorder associated with Friedreich's ataxia (FRDA) is classically described as ataxic dysarthria. However, variable neuropathology beyond the cerebellum, which may include the corticospinal and corticobulbar tracts, means that the dysarthria can be mixed rather than a pure ataxic dysarthria. Aims: To characterize…

The purpose of this study was to address the hypothesis that childhood apraxia of speech (CAS) is influenced by an underlying deficit in sequential processing that is also expressed in other modalities. In a sample of 21 adults from five multigenerational families, 11 with histories of various familial speech sound disorders, 3 biologically…

While a number of authors have suggested that patients with palilalia typically show a tendency to repeat words or phrases with an increasing rate, others maintain that an accelerating speech rate is not essential. The present paper reports the results of an instrumental analysis of the reiterations in a 60-year-old man with palilalia. Results…

Results are presented from an auditory and acoustic analysis of the speech of an adult male with impaired prosody and articulation due to brain haemorrhage. They show marked effects on phonation, speech rate and articulator velocity, and a speech rhythm disrupted by "intrusive" stresses. These effects are discussed in relation to the speaker's…

This case report describes the case of a 52-year-old man with bilateral central lingual paralysis following a myocardial infarction. Analysis of speech recordings 15 days and 18 months after the attack were acoustically analyzed. The case demonstrates the usefulness of acoustic analysis to detect slight acoustic differences. (DB)

This volume examines the ramifications of individual differences in therapy outcomes for a wide variety of communication disorders. In an era where evidence-based practice is the clinical profession's watchword, each chapter attacks this highly relevant issue from a somewhat different perspective. In some areas of communication disorders,…

Purpose: The primary goal of this case study was to describe the speech, prosody, and voice characteristics of a mother and daughter with a breakpoint in a balanced 7;13 chromosomal translocation that disrupted the transcription gene, "FOXP2" (cf. J. B. Tomblin et al., 2005). As with affected members of the widely cited KE family, whose…

A woman with Down syndrome, who had shown selective mutism for more than 14 years, successfully participated in a program designed to reinforce communication and gradually increase the number of words spoken to one person and then to others. Nonaversive behavior methods were used and response initiative procedures were developed. (Contains…
