As the severity of the dysarthria increases, the patient may also lengthen more segments as well as increase the degree of lengthening of each individual segment. [ 12 ] Common clinical features of ataxic dysarthria include abnormalities in speech modulation, rate of speech, explosive or scanning speech , slurred speech , irregular stress ...
It has features resembling other complex tics such as echolalia or coprolalia, but, unlike other aphasias, palilalia is based upon contextually correct speech. [ 2 ] It was originally described by Alexandre-Achille Souques in a patient with a stroke that resulted in left-side hemiplegia, [ 3 ] although a condition described as auto-echolalia in ...
Patients with pure EA5 present with recurrent episodes of ataxia with vertigo. Between attacks they have nystagmus and dysarthria. These patients are responsive to acetazolamide. Both juvenile myoclonic epilepsy and EA5 are a result of mutations in CACNB4, a gene that encodes the calcium channel β 4 subunit. This subunit coassembles with α ...
However, cases of expressive aphasia have been seen in patients with strokes in other areas of the brain. [8] Patients with classic symptoms of expressive aphasia in general have more acute brain lesions, whereas patients with larger, widespread lesions exhibit a variety of symptoms that may be classified as global aphasia or left unclassified ...
Dysarthria is a weakness or paralysis of speech muscles caused by damage to the nerves or brain. Dysarthria is often caused by strokes, Parkinson's disease, [9] ALS, head or neck injuries, surgical accident, or cerebral palsy. Aphasia; Dysprosody is an extremely rare neurological speech disorder. It is characterized by alterations in intensity ...
Flaccid dysarthria is a motor speech disorder resulting from damage to peripheral nervous system (cranial or spinal nerves) or lower motor neuron system. Depending on which nerves are damaged, flaccid dysarthria affects respiration, phonation, resonance, and articulation. It also causes weakness, hypotonia (low-muscle tone), and diminished ...
There has been no evidence that ethnicity, age, or genetics has any impact on the development of dysprosody. [10] In another reported case in 2004, a patient presented with dysprosody under interesting circumstances. The patient underwent surgery to correct a Reinke's edema, which originates in the vocal folds of the larynx. After the surgery ...
Ataxia (from Greek α- [a negative prefix] + -τάξις [order] = "lack of order") is a neurological sign consisting of lack of voluntary coordination of muscle movements that can include gait abnormality, speech changes, and abnormalities in eye movements, that indicates dysfunction of parts of the nervous system that coordinate movement, such as the cerebellum.
