apraxia of speech
Motor speech disorder affecting the ability to plan and coordinate the precise movements needed for speech production.
Full Definition
Apraxia of speech is a neurologic motor speech disorder that affects the brain's ability to coordinate the complex oral motor movements necessary for speech production. Unlike dysarthria, which involves weakness or paralysis of speech muscles, apraxia of speech results from impaired motor planning and programming. Patients typically demonstrate inconsistent speech errors, difficulty with speech initiation, and groping behaviors as they attempt to position their articulators correctly. The condition commonly occurs following left hemisphere strokes affecting premotor areas. Treatment focuses on repetitive motor practice and speech rhythm techniques.
Usage
Usage note: Distinct from dysarthria (muscle weakness) and aphasia (language disorder).
