The following patterns emerged: (1) Head only and head + voice were the most commonly observed anatomical distribution of tremor. (2) Jaw tremors were rare, and face and tongue tremors, exceedingly rare. (3) There was a general layering\u2010on of tremor from head to head + voice to head + voice + jaw in more advanced cases. (4) Women were more likely to have head tremors than men, although there was no sex predilection tremor in other locations.
