Articulation in apraxia of speech

Developmental Apraxia of Speech

Apraxia of speech: an overview.

Apraxia of speech (AOS) is a motor speech disorder that can occur in the absence of aphasia or dysarthria. AOS has been the subject of some controversy since the disorder was first named and described by Darley and his Mayo Clinic colleagues in the 1960s. A recent revival of interest in AOS is due in part to the fact that it is often the first symptom of neurodegenerative diseases, such as prim...

The specific relation between perception and production errors for place of articulation in developmental apraxia of speech.

Developmental apraxia of speech is a disorder of phonological and articulatory output processes. However, it has been suggested that perceptual deficits may contribute to the disorder. Identification and discrimination tasks offer a fine-grained assessment of central auditory and phonetic functions. Seventeen children with developmental apraxia (mean age 8:9, years:months) and 16 control childr...

Assessment and treatment of childhood apraxia of speech: An inquiry into knowledge and experience of speech-language pathologists

Objectives: The present research aimed to identify the assessment and treatment processes implemented by Iranian speech-language pathologists (SLPs) for CAS and to investigate the possibility of impact of their knowledge level and years of experience on their choice of assessment and treatment. Methods: A cross-sectional method using survey design was employed to obtain a sample of 260 SLPs w...

Neurophysiology of speech differences in childhood apraxia of speech.

Event-related potentials (ERPs) were recorded during a picture naming task of simple and complex words in children with typical speech and with childhood apraxia of speech (CAS). Results reveal reduced amplitude prior to speaking complex (multisyllabic) words relative to simple (monosyllabic) words for the CAS group over the right hemisphere during a time window thought to reflect phonological ...
