Which term describes a speech disorder caused by muscular issues due to brain or nervous system damage?

The term that accurately describes a speech disorder resulting from muscular issues due to damage in the brain or nervous system is dysarthria. This condition affects the physical ability to produce speech, leading to slurred or slow speech that can be difficult to understand. It is often associated with neurological conditions such as stroke, Parkinson’s disease, or cerebral palsy, which impair the control of the muscles involved in speaking.

Dysarthria specifically addresses the motor difficulties related to speech production rather than challenges with understanding or formulating language. Other terms in the choices refer to different types of communication and language disorders: dysphonia relates to issues with voice quality, dyslexia pertains to difficulties in reading due to language processing, and dysgraphia affects writing ability. Each of these conditions has its own distinct characteristics, but dysarthria is the one that aligns with the muscular impairment due to nervous system damage.
