Parkinsonian dysarthria

Parkinson's dysarthria (d parkinsonia)

It is based on a gradually developing neurological pathology caused by organic damage to those parts of the brain that are responsible for the coherence of speech movements, including the muscles of the vocal apparatus - the larynx, tongue, soft palate and pharynx. Dysarithria due to damage to the extrapyramidal areas of the cerebral cortex manifests itself in a predominant disturbance of speech motor skills, mainly associated with the muscle fibers of the brachial and cervical innervation fibers. In this case, the pronunciation of speech sounds and their perception are usually not impaired and there is no stuttering. The development of dysarthria always leads to some neurological “lethargy” when attempting to speak (logorrhea), as well as deviations in some motor, dynamic and articulatory functions. The course of dysarthyria is lifelong, in most cases it intensifies and cannot be completely cured.
