Motor Speech Disorders: Apraxia and Dysarthria.

Developmental co-ordination disorder (DCD), also known as dyspraxia, is a condition affecting physical co-ordination. It causes a child to perform less well than expected in daily activities for their age, and appear to move clumsily. DCD is thought to be around 3 or 4 times more common in boys than girls, and the condition sometimes runs in.

Motor speech difficulties is the term used to describe problems with producing speech due to muscle control, weakness, paralysis, incoordination or speed of movement. Impaired or restricted muscle movement and coordination can cause difficulties in producing the correct sounds for speech. This can make it difficult for the child to be understood by others. Our speech and language therapists.

Dysarthria is a weakness or paralysis of speech muscles caused by damage to the nerves or brain. Dysarthria is often caused by strokes, Parkinson's disease, ALS, head or neck injuries, surgical accident, or cerebral palsy. Dysprosody is the rarest neurological speech disorder. It is characterized by alterations in intensity, in the timing of.

Abnormalities of speech after neurological insult were subdivided into aphasias and dysarthrias before the contribution of Darley, who with colleagues delivered an unpublished paper on the topic in 1969. 7 In this lecture, Darley was the first to use the term apraxia of speech and to attribute a specific disorder of speech—interposed between aphasia and dysarthria—to impaired motor.

A child with a motor speech disorder may be able to form one word clearly, but speech will become difficult to understand as statements get longer. How are motor speech disorders diagnosed? A comprehensive speech and language evaluation is necessary to diagnose if a motor speech disorder is contributing to a child’s communication impairment.

Acquired motor speech disorders are changes to voice and speech associated with damage to the central and peripheral nervous systems. This includes disorders associated with the nerve-muscle junction, e.g. myasthenia gravis and with muscle function, e.g. muscular dystrophies. Severity may range from 'changes imperceptible to listeners but felt by speakers' through to 'absence of any speech or.

Motor-speech disorders are speech disorders resulting from neurological damage that affects the motor control of speech muscles or motor programming of speech movements. The most common motor-speech disorders are dysarthria and apraxia of speech. The dysarthrias are oral communication problems due to weakness, incoordination, or paralysis of the speech musculature.

Apraxia of speech (AOS)—also known as acquired apraxia of speech, verbal apraxia, or childhood apraxia of speech (CAS) when diagnosed in children—is a speech sound disorder. Someone with AOS has trouble saying what he or she wants to say correctly and consistently. AOS is a neurological disorder that affects the brain pathways involved in planning the sequence of movements involved in.

When evaluating a child’s articulation, an SLP may identify symptoms of a developmental disorder known as apraxia of speech (also known as childhood apraxia of speech, or CAS). CAS is a motor speech disorder that results from poor motor planning from the brain to the articulators (e.g., lips and tongue). The resulting incoordination often has.

Apraxia of speech (AOS) is an acquired oral motor speech disorder affecting an individual's ability to translate conscious speech plans into motor plans, which results in limited and difficult speech ability. By the definition of apraxia, AOS affects volitional (willful or purposeful) movement patterns, however AOS usually also affects automatic speech.

Foreign Accent Syndrome (FAS) is a relatively rare motor speech disorder in which the pronunciation of a patient is perceived by listeners of the same language community as distinctly foreign. FAS has been well documented in adult patients with etiologically heterogeneous, though mostly vascular brain lesions affecting the motor speech network of the language dominant hemisphere. In addition.

A phonological process disorder is a simplification of the sound system that also affects intelligibility. Students with phonological process problems demonstrate difficulty in acquiring a phonological system; involving organizing the patterns of sounds in the brain and the output, not necessarily in the motor production of the sounds like Articulation errors.
