Abstract


Essential tremor (ET) is one of the most common tremor disorders in the world. Despite this, only two medications have received Level A recommendations from the American Academy of Neurology to treat it (primidone and propranolol).

This review discusses some of the methodological issues that should be addressed for quality clinical drug development in ET.
