The components of the speech system most prominently involved Cineradiographic and spectrographic analyses were performed to study the speech production of a subject who presented the classical neurologic signs of cerebellar lesion and who had speech characteristics like those that have been reported for ataxic dysarthria… 1 1 Ataxic Dysarthria results from cerebellar damage deficits in coordination inaccuracy in force, range, timing and direction of speech movement bilateral or diffuse damage 2 Etiology same as all others - toxic-metabolic - acute or chronic alcoholism antiseizure meds or psychotrophic drugs hypothyrodism normal pressure hydrocephalus 3 Cerebellar Damage According to Duffy (1995), it can affect respiration, phonation, resonance and articulation, but its characteristics are most pronounced in articulation and prosody.

Dysarthrias are characterized by weakness and often, the abnormal muscle tone of the speech … cerebellum and then back to cortex by way of deep cerebellar nuclei and Damage to the peripheral nervous system (PNS) is responsible for this type of dysarthria. Spastic dysarthria: Speech may be slow and labored, with poor articulation. Learning outcomes: The reader will: (1) be able to recognize the principle characteristics of ataxia; (2) recognize that not all speech tasks are equally sensitive to ataxic dysarthria; (3) recognize that voice quality changes may play an important role in recognizing different genetic types of ataxia.

People with spastic dysarthria may have speech problems alongside generalized muscle weakness and abnormal reflexes. The cerebellum is the part of the brain responsible for receiving sensory information and regulating movement. They may feel the pulse in their chest, neck, or wrists. cerebellar disease rather than a focal lesion, Vascular lesions - aneurysms, AVMs, hemorrhage in brainstem or midbrain, Degenerative diseases - MS, Friedrich’s ataxia, OPCA, Hypothyroidism & normal pressure hydrocephalus, Hypotonia and reduced resistance to passive movement, Dysmetria, dysrhythmia & dysdiadochokinesis - ataxia, Often normal with respect to structures at rest and in sustained inflammatory conditions, such as autoimmune diseases, vascular conditions, such as stroke or Moyamoya disease, exposure to toxic substances, such as alcohol, heavy metals, or, rigidity or reduced movement in the face and neck, involuntary jerking or flailing movements, tremors or involuntary movements of the jaw, tongue, or lip, overly sensitive or undersensitive gag reflex, make different consonant and vowel sounds, electromyography, which tests muscle function, exercises to strengthen the muscles in the mouth, jaw, and throat, breathing techniques to increase or decrease the volume of a person’s voice, techniques to address specific speech problems, such as teaching people to pause when talking to slow down their speech, maintaining eye contact with the listener, having conversations in a quiet environment, using gestures and facial expressions to convey meaning, using different words to reiterate a message, carrying a pen and notepad to communicate via written word, if necessary, reducing external distractions and finding a quiet, calm place to have a conversation, asking for clarification when having trouble understanding something, avoiding finishing the person’s sentences or correcting errors.

PEDIATRIC DYSARTHRIA. The hallmark of flaccid dysarthria is difficulty pronouncing consonants. Dysarthria shares many of its symptoms with other types of neurological disorders, such as aphasia, dysphasia, and apraxia. Love and Wanda G. Webb (1992) Clinical Speech Syndromes of the Motor Systems Neurology for the Speech-Language Pathologist 10.1016/B978-0-7506-9076-8.50014-9 Perceptual and acoustic data were obtained from 14 individuals (seven men, seven women) with ataxic dysarthria for several speaking tasks, including sustained vowel phonation, syllable repetition, sentence recitation, and conversation.
