Tremor is not understood completely, and pharmacotherapy for all tremor disorders is inadequate. Fortunately, deep brain stimulation is effective for the most common and disabling tremor disorders. Our understanding of pathologic tremors has increased at an accelerating pace during the past 30 years, and this will hopefully lead to improved pharmacotherapy in the near future.
