Paroxysmal Movement Disorders

Abstract

Event Abstract Back to Event Paroxysmal Movement Disorders Ninith Kartha1* 1 Loyola University Health System, Department of Neurology, United States Learning Objectives: Recognize the clinical features and etiologies of the group of disorders known as paroxysmal dyskinesias and episodic ataxias. Review what is known about the genetics of the paroxysmal dyskinesias and episodic ataxias. Recognize when and which therapies are likely to be beneficial for management of these disorders. The term paroxysmal dyskinesia refers to a group of movement disorders manifested by brief or prolonged attacks of chorea, athetosis or dystonia or a combination of these features. Paroxysmal ataxias are typically referred to as episodic ataxias. Although several names and classification systems have been used over the years to identify the paroxysmal dyskinesias, the most common method separates them into paroxysmal kinesigenic dyskinesia (PKD), paroxysmal nonkinesigenic dyskinesia (PNKD) paroxysmal exertional dyskinesia (PED) and paroxysmal hypnogenic dyskinesia (PHD). PKD tends to be briefer in duration than PNKD and to respond better to anticonvulsant therapy. PHD is often associated with frontal lobe epilepsy. Episodic ataxias have been associated with abnormal gait, in coordination, ocular motility disorders, and tremor, and some cases respond well to acetazolamide. Due to the rarity of these conditions, the difficulty patients have in describing their symptoms and the typical absence of abnormal neurologic findings in between episodes, they are often misdiagnosed or under diagnosed. The genetic basis of many of these disorders will be discussed as well as secondary causes that have been identified in symptomatic cases.
