Tics and myoclonus

Abstract

This article describes advances occurring over the last year in the pathophysiology, etiology and treatment of tics and myoclonus. Progress is being made in the clinical definition of Tourette syndrome (TS). The search for the TS gene has already excluded more than 50% of the autosomal genome. Progress in the understanding of myoclonus is slow but continuous. Several paper are devoted to clinical aspects but much recent attention has been focused on the pathophysiological mechanisms underlying myoclonus.
