Differentiating Apraxia from other Motor Speech Disorders.
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.
Keywords: primary progressive aphasia, motor speech disorders, dysarthrias, apraxia of speech, primary progressive apraxia of speech. Mesulam's (1982) widely recognized seminal description of six cases with “slowly progressive aphasia” included two individuals with buccofacial apraxia, one with limb apraxia, and one with constructional apraxia. Subsequent clinical descriptions and research.
Motor Speech Disorders (Dysarthria and Apraxia) When the normal speech pattern is interrupted or verbal communication is adversely affected, this is called a motor speech disorder. Motor speech disorders are either cerebral in nature, meaning the brain or nervous system have been damaged, or neuro-muscular, meaning that the muscles used to produce speech are not cooperating with the brain.
What are motor speech disorders? A motor speech disorder is present when a child struggles to produce speech because of problems with motor planning or muscle tone needed to speak. There are two major types of motor speech disorders: dysarthria and apraxia. What is dysarthria? Dysarthria, often called slurred speech, is defined as slow, imprecise, and distorted speech that is the result of.

Sometimes, a motor speech disorder (MSD)—dysarthria or apraxia of speech—is the predominant sign of such illnesses. The fact that MSDs (and other neurologic communication disorders) often can be linked to disease location, and sometimes to specific diseases, even when localization and diagnosis have not yet otherwise been established, is often under-recognized.
Verbal apraxia is a motor speech planning disorder. This individual does not have any facial weakness. A person with verbal apraxia is aware of the words they want to say, but have difficulty with planning and coordinating the muscle movements for speech production. Writing is not typically affected if a person is suffering from verbal apraxia only but may be present if a limb apraxia has been.
