What other tremors are variants of Essential Tremor?
Besides orthostatic tremor, other types of tremors are also considered to be variants of Essential Tremor.
However, some authors argue that the pharmacologic differences between these tremors and Essential Tremor support the notion that they represent distinct entities.
There is evidence, for example, that some isolated site (head tremor) and task-specific tremors, such as primary handwriting tremor, actually represent forms of dystonic tremors.
This controversy will not be settled until biologic markers for Essential Tremor and dystonia are available
