Dysarthria Corkovaya

Dysarthria is a speech disorder manifested in disturbances in sonority, tempo, rhythm, melody, and intonation of speech; motor dysfunction of the organs of the articulatory apparatus. In its origin, not only the lack of innervation of the muscles of the speech apparatus plays a role, but also a violation of the neurodynamics of speech in its cerebral support. Dysarthria occurs as a consequence of peripheral or central paresis, as well as with central paralysis of the speech muscles, cicatricial lesions, organic ataxia, diffuse brain lesions, hyperkinesis (spastic forms), and psychogenic disorders. Based on the nature of speech symptoms and clinical manifestations, two main forms of dysarthria are distinguished: spastic (violent) and parasynditic (violently accelerated).
