Prolonged ingestion can result in acute cyanide poisoning, a goiter, spastic paraparesis, or ataxic neuropathy. Scanning speech is an ataxic dysarthria in which syllable durations are equalized. There are three major types of dysarthria in cerebral palsy&colon; spastic, dyskinetic (athetosis), and ataxic. Different medications have been used to temporarily treat ataxic cerebral palsy. Non-spastic cerebral palsy is divided into two groups, ataxic and dyskinetic. An example of X-linked ataxic condition is the rare fragile X-associated tremor/ataxia syndrome or FXTAS. It is also a feature of ataxic dysarthria. Diagnosis of ataxic cerebral palsy is based on clinical assessment using standardized assessment tools. There are three main CP classifications by motor impairment&colon; spastic, ataxic, and athetoid/dyskinetic. Patients with ataxic gait have problems balancing and display an unstable wide walk. Like all forms of CP, there is no "cure" for ataxic cerebral palsy. As the breathing pattern deteriorates, it merges with ataxic respirations. There may also be slurring of speech, tremor of the voice and ataxic respiration. Scanning speech, like other ataxic dysarthrias, is a symptom of lesions in the cerebellum. It has been noted that ataxic lesions accompany the migraine coma.
