"&amp;lt;p&amp;gt;&amp;lt;strong&amp;gt;Definition:\u00A0&amp;lt;/strong&amp;gt;Anarthria (a n\u00E1arthree \u0259) is the most severe form of dysarthria that results in the loss of articulate speech.\u00A0 It is due to a loss of neuromuscular control of the speech muscles. Patients with anarthria have the motivation to speak but are unable to do so. Dysarthria, also known as dysarthosis, is a motor speech disorder that affects the muscles used for speech production. The muscles include the lips, tongue, vocal folds, and diaphragm.&amp;lt;/p&amp;gt;&amp;lt;h3&amp;gt;Types of Dysarthria&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;All types of dysarthria are characterized by slurring of speech. Vowels may be distorted. The level of dysarthria depends on the degree of damage to the neurological system.&amp;lt;/p&amp;gt;&amp;lt;ul&amp;gt;&amp;lt;li&amp;gt;Spastic dysarthria\u2013 caused by damage to the pyramidal tract&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Hyperkinetic dysarthria \u2013 caused by lesions of the basal ganglia&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Hypokinetic dysarthria \u2013 associated with Parkinson\u2019s disease&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Ataxic dysarthria \u2013 caused by damage to the cerebellar control circuit&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Flaccid dysarthria \u2013 caused by damage to the cranial nerves&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Mixed dysarthria \u2013 caused by damage to the upper or lower motor neurons&amp;lt;/li&amp;gt;&amp;lt;/ul&amp;gt;&amp;lt;h3&amp;gt;Causes of Dysarthria&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Dysarthria and the more severe form, anarthria, is caused by brain damage. The most common causes of dysarthria include disorders of the neurological system such as stroke or brain injury. It can also occur during birth, as seen in cerebral palsy or muscular dystrophy.\u00A0 It may occur later in life due to one of the following conditions that involve the nervous system:&amp;lt;/p&amp;gt;&amp;lt;ul&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/what-is-stroke-3146478&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;1&amp;quot;&amp;gt;Stroke&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Traumatic brain injury&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Brain tumor&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/parkinsons-disease-related-speech-and-language-problems-2612189&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;2&amp;quot;&amp;gt;Parkinson\u2019s disease&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Amyotrophic lateral sclerosis (&amp;lt;a href=&amp;quot;https://www.verywell.com/als-and-ms-symptoms-2440783&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;3&amp;quot;&amp;gt;ALS&amp;lt;/a&amp;gt;), or Lou Gehrig\u2019s disease&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/what-is-huntingtons-disease-symptoms-and-causes-98737&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;4&amp;quot;&amp;gt;Huntington\u2019s disease&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/speech-difficulties-as-a-symptom-of-multiple-sclerosis-2440788&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;5&amp;quot;&amp;gt;Multiple sclerosis&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/myasthenia-gravis-2860863&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;6&amp;quot;&amp;gt;Myasthenia gravis&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/wilsons-disease-2861046&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;7&amp;quot;&amp;gt;Wilson\u2019s disease&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/introduction-to-guillain-barre-syndrome-2488658&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;8&amp;quot;&amp;gt;Guillain-Barre syndrome&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;&amp;lt;a href=&amp;quot;https://www.verywell.com/guide-to-lyme-disease-190012&amp;quot; data-component=&amp;quot;link&amp;quot; data-source=&amp;quot;inlineLink&amp;quot; data-type=&amp;quot;internalLink&amp;quot; data-ordinal=&amp;quot;9&amp;quot;&amp;gt;Lyme disease&amp;lt;/a&amp;gt;&amp;lt;/li&amp;gt;&amp;lt;/ul&amp;gt;&amp;lt;p&amp;gt;Certain medications, such as narcotics or sedatives, can also cause dysarthria.&amp;lt;/p&amp;gt;&amp;lt;h3&amp;gt;Symptoms of Dysarthria&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Patients with dysarthria demonstrate the following characteristics of speech:&amp;lt;/p&amp;gt;&amp;lt;ul&amp;gt;&amp;lt;li&amp;gt;Slowed rate of speech&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Mumbling quality to speech that is difficult to understand&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Limited movement of the tongue, lip, and jaw&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Abnormal vocal pitch&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Abnormal rhythm to speech&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Hoarseness or breathiness to speech&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Nasal or stuffy sounding speech&amp;lt;/li&amp;gt;&amp;lt;li&amp;gt;Inability to speak loudly&amp;lt;/li&amp;gt;&amp;lt;/ul&amp;gt;&amp;lt;h3&amp;gt;Diagnosis of Dysarthria&amp;lt;/h3&amp;gt;&amp;lt;p&amp;gt;Dysarthria and its more severe form, anarthria, is diagnosed by a medical professional.

A variety of techniques will be used during treatment. If muscles are weak, strengthening exercises are appropriate. If muscles have too much tone, other exercises will be used. Typically treatment includes incorporating relaxation techniques, lingual, labial and mandibular exercises, including isometrics, and phonetic stimulation.&amp;lt;/p&amp;gt;&amp;lt;p&amp;gt;Dysarthria can disappear a few months after the stroke. If it is still present, a more rigid therapy program will be suggested. The goal is to bring back normal speech patterns and provide the patient with a more independent and confident way of living.&amp;lt;/p&amp;gt;"^^<http://www.w3.org/2001/XMLSchema#string>
