Methamphetamine-induced choreoathetosis: A case report

Chorea - Is Diabetes Mellitus the Cause?

Diabetic striatopathy (DS) is an uncommon complication of diabetes characterized by hemiballismus-hemichorea, often accompanied by reversible striatal hyperintensity on neuroimaging. Diabetes is the most common metabolic cause of hemiballismus and hemichorea. However, it is underreported as clinicians do not always consider it in the diagnosis of new movement abnormalities. The prognosis is generally excellent, and management involves glycemic control and anti-chorea medications. We present a case of a patient with bilateral chorea and ballismus and classic MRI findings of DS, though his history of diabetes and substance use confounds the clinical picture of DS.

Choreoathetoid movements associated with methamphetamine: A case report and review of literature

BACKGROUND AND OBJECTIVES

Physicians and psychiatrists often encounter patients in the emergency department presenting after methamphetamine use. While physical and psychiatric manifestations associated with methamphetamine use are well known, movement disorders are relatively less common. The aim of this case report is to add to existing literature awareness about the possibility of movement disorders occurring after methamphetamine use, discuss the possible mechanism by which such use leads to dyskinesia, and describe possible management strategies.

METHODS AND RESULTS

In this case report, we describe choreoathetoid movements occurring in a young female after relatively short-term methamphetamine use.

DISCUSSION AND CONCLUSIONS

Evidence for treatment of methamphetamine induced choreoathetosis is limited. Expectant management of such symptoms is a viable option if there are no additional comorbidities that require therapy.

SCIENTIFIC SIGNIFICANCE

Clinicians should be alert to the possibility of movement disorders in methamphetamine users and familiar with treatment options. (Am J Addict 2018;XX:1-4).
