Essential tremor

A variety of treatment options for essential tremor are available today which makes it possible, but also necessary, to select the most appropriate solution for the individual patient. The patient’s subjective experience of the tremor’s severity and the degree of impairment and disability that it causes in the patient’s life are more important than the objective assessment during the patient’s clinic visit. Such assessment may be difficult. Studies have shown that on average, physical and mental quality of life measures are lower in essential tremor patients compared with healthy individuals. Nevertheless, a considerable number of essential tremor patients have a low degree of impairment or disability and little emotional suffering from their disorder. The non-pharmacologic treatment options outlined above are considered for all patients with essential tremor.

Essential tremor is the most common form of tremor, and probably the most common movement disorder in general. Unfortunately, there is no uniformly accepted definition of essential tremor. Widely used definitions are those developed by the Movement Disorder Society’s Tremor Investigation Group and those used in the Washington Heights-Inwood genetic study, but several others exist. However, the percentage of individuals fulfilling different commonly used diagnostic criteria for essential tremor has shown considerable variation. The Movement Disorder Society’s Tremor Investigation Group defines essential tremor as a bilateral, largely symmetric postural or kinetic tremor involving hands and forearms that is visible and persistent, and in which there is no other explanation for the tremor. Additional or isolated head tremor is compatible with essential tremor as long as there is no abnormal head posturing. In view of the difficulties in applying essential tremor diagnostic criteria, it may be reasonable to consider treating individuals even if they do not strictly fulfill these criteria. Probably, essential tremor reflects a clinical syndrome rather than a single disease entity.

Only about half of essential tremor patients report a positive family history, which means that the term "familial tremor" is not congruent with essential tremor. Although the diagnostic criteria require "largely symmetric" tremor, 50% of 487 consecutive individuals diagnosed with essential tremor at Mayo Clinic had asymmetrical disease, most of them with greater tremor severity on their dominant side. A tremor strictly confined to an ipsilateral arm and leg tremor is less likely essential tremor and more likely secondary to a structural lesion. Essential tremor usually has a frequency of 5 to 10 Hz and no latency to onset.
