Abstract

A 16‐year‐old girl with a history of hereditary spastic paraparesis developed the subacute onset of severe clonus and new upper‐extremity spasticity due to thyrotoxicosis. This case demonstrates the ability of hyperthyroid states to worsen symptoms of spasticity in a child with an underlying spastic disorder. It also demonstrates the importance of investigating for common systemic diseases as a cause of movement disorders even in children with underlying known genetic disorders. © 2004 Movement Disorder Society
