Her choreoathetosis remarkably improved due to olanzapine, and subsequently, cerebellar signs became obvious upon neurologic examination (video, http://link...

a 14-year old boy was presented with q rare form ofmovement-induced drop attacks, which was also present in his father. 17jis case was, therefore, labeled as familial paroxysmal kinesigenic choreoathetosis.

We present a case of hypoparathyroidism, demonstrating extensive intracranial calcification, not only in basal ganglia, but also outside the extrapyramidal system. The patient presented with an unexplained epileptifors disorder, accompanied by extrapyramidal dysfunction in the form of choreoathetosis and hemiballismus. Hemiballismus is reported for the first time to our knowledge in association...

Background/Objective: Dystonia-choreoathetosis is highly resistant to medical treatment and is associated with major disability in patients with normal intelligence. Since deep brain simulation (DBS) has been shown to improve movement disorder in patients with dystonia, will it be equally useful in dystonia-choreoathetosis? Design: Prospective, multicenter, open-label study. Participants/Method...

In a controlled trial, baclofen (mean dose 45 mg daily) signficantly increased disability from Parkinsonism in 12 patients with the long-term levodopa syndrome. Peak dose choreoathetosis was not improved but benefit was observed in all four patients with "off period dystonia." Adverse side effects were common and severe, and included visual hallucinations, vomiting, and dizziness.
