Difficulty with speech articulation due to weakness or poor coordination of the muscles used for speaking. The language content remains normal, but speech may be slurred, slow, or difficult to understand.
From Greek 'dys-' (difficult) + 'arthron' (joint/articulation), meaning 'difficult articulation.' The term was established in neurology during the 19th century to describe motor speech disorders distinct from language problems.
Dysarthria is like trying to play a musical instrument with fingers that won't cooperate - the music (language) in your head is perfect, but the execution is flawed! Unlike aphasia where the problem is with language itself, dysarthria patients have intact thinking and language but their speech muscles won't obey, often making them sound intoxicated when they're completely sober.
