Essential Tremor

Essential tremor (ET) is the most common movement disorder. The tremor is present during action and absent at rest. (It may be postural, trajectory or occur while performing a task.) The pathophysiologic mechanism of tremor is not well understood. Mechanical, reflex oscillators and central neuronal pacemakers or circuits (e.g. olivo-cerebellar-thalamic circuit) have all been implicated in various types of tremor.

Essential tremor is more symmetric than the tremor of PD. Rigidity and bradykinesia are not seen with essential tremor. The tremor often involves the upper extremities, head and voice. Unlike PD, there is no significant response to anti-Parkinson medications. A family history is positive in half of patients. In patients with hereditary ET, there is autosomal-dominant inheritance. Men and woman are affected equally. Head tremor is usually mild and of a "no-no" type.

There are a number of surgical options for the treatment of tremor. The target for the treatment of isolated tremor with either ablative surgery or deep brain stimulation is the ventro-intermediate nucleus (VIM) of the thalamus.
