Dysarthria
Pronunciation: dis-AR-three-ah
A motor speech disorder resulting from neurological damage affecting speech muscle control.
Full Definition
Dysarthria is a group of motor speech disorders caused by weakness, paralysis, or incoordination of the speech muscles due to damage to the central or peripheral nervous system. Unlike aphasia, which affects language processing, dysarthria affects the physical production of speech while language comprehension and formulation remain intact. Symptoms include slurred speech, altered voice quality, reduced speech volume, and difficulty with articulation. Speech-language pathologists play a crucial role in assessment and treatment, using techniques such as oral motor exercises, breathing training, and assistive communication devices.
Usage
Usage note: Often confused with 'dysphasia' (language disorder) and 'dysphagia' (swallowing disorder); ensure proper spelling and context.
