"In neurological diagnostics, language disorders are generally divided into dysarthria and aphasia. Dysarthria refers to a speech disorder caused by impairments in the muscles involved in articulation, such as the tongue, palate, lips, and larynx, as well as the nervous system that controls these muscles. Aphasia, on the other hand, is a condition where a person has difficulty with language expression and comprehension despite normal peripheral speech organs, as well as an absence of consciousness and hearing impairments.In traditional Korean medicine, speech is associated with the heart. Excessive talkativeness and agitation are often seen as signs of an 'excess' or 'heat' condition, while quietness and a lack of speech are considered 'deficiency' or 'cold' conditions. In either case, accurately diagnosing the condition of the heart and providing precise treatment is essential."
