Dysarthria is a speech disorder caused by a stoke, cerebrum damage, tumors, or Parkinson's disease. Dysarthria damages movements in muscles used for speech production. These muscles incorporate the tongue, vocal folds, lips and diaphragm. Dysarthria is weakened in communication due to shortcoming, loss of motion and incoordination of speech. It influences your pitch, loudness, voice quality, prosody, respiration and articulation. There are numerous sorts of dysarthria's, which are characterized relying upon the site of injury. The sorts of dysarthrias are: Flaccid Dysarthria situated in the Peripheral nervous system or lower motor neuron. It disrupts the flow of neural impulses along the lower motor neuron that innervates the muscles of phonation,

The speech disorders tend to be mild and moderate in severity. This disorder also can be temporary; it can be resolve in days or weeks. Ataxic Dysarthria located in the cerebellum. It generally results from bilateral; or generalized damage to the cerebellum; focal lesions typically affect area of superior peduncle, lateral hemisphere or paravermal regions. Friedreinch ataxia, Olivopontocerebellar atrophy, strokes, traumatic brain injury, tumors, toxic conditions, metabolic conditions and neurotoxic levels of several drugs can cause ataxic dysarthria. The characteristics for ataxic dysarthria are imprecise consonants, irregular articulatory breakdowns, prolonged phonemes, prolonged intervals and slow rate. According to Rachel Stocks, she stated that a person with ataxic dysarthria appear to have movements poorly controlled, inaccurate and slower than normal (p.820). Hypokinetic dysarthria is caused by damagaging the basal ganglia control circuit. Etiologies for this disorder are Idiopathic Parkinson's disease, Neuroleptic-Induced Parkinsonism, Postencephalitic …show more content…
A person with apraxia will be unable to put words together, use the correct word, pronounce long words or make sentences. It is also the inability to create and sequence the neural impulses necessary to create the appropriate movements for speech. Apraxia is characterized by limiting prosody, articulation errors, slowed rate and the visible groping about the tongue, lips and mandible. Apraxia is divided into two categories, which are Acquired Apraxia that results from a brain damage, and the other one is Developmental Apraxia that results from unknown congenital etiology. Acquired Apraxia of speech is a motor speech disorder of neurologic origin that is characterized by slow rate of speech, difficulties in sound production and disrupted speech (Wambaugh, 2013, p.84). The most common etiology for acquired apraxia is strokes. Developmental apraxia is a disorder that exhibits severe articulation problems due to difficulty formulating and executing motor plans for speech. The motor control problems in apraxia of speech are not manifest in speech alone, they can be observed in any complex movement patterns using the speech production system. In the article Enwefa states that patients with developmental apraxia have trouble producing and sequencing sounds, syllables, including words, in absence of any weakness in the muscles of the face, tongue, lips and jaw (p.966). Patients with
