Early-onset dystonia after supplementary motor area infarction

J Stroke Cerebrovasc Dis. 2014 May-Jun;23(5):1267-8. doi: 10.1016/j.jstrokecerebrovasdis.2013.09.028. Epub 2014 Jan 7.

Abstract

A 63-year-old patient with the right supplementary motor area infarct developed early-onset dystonia in the left upper extremity. The mechanisms involved in the genesis of focal dystonia are discussed with emphasis on cortical basal ganglia circuit and efferent projections from the supplementary motor area.

Keywords: Movement disorders; acute onset; dystonia; infarction; supplementary motor cortex.
