Abstract
Essential tremor (ET) is currently classified as asyndrome rather than aunique disease, primarily involving monosymptomatic action tremor in both hands. Different etiologies are presumed to underlie this condition. Currently only afew monogenetic conditions are known to present with this syndrome. If accompanied by additional symptoms that do not in themselves constitute a new syndrome, such as abnormal tandem gait or postures, the syndrome should be diagnosed as "ET plus". ET is associated with abnormal rhythmic activation of the cerebello-thalamo-cortical tremor circuit. Despite its strong heritability, the genetics of ET have not been elucidated as yet. Age-correlated tremor is one of the presumed subgroups of ET. Late onset is associated with a shortened life expectancy. From a treatment perspective, propranolol and primidone represent the drugs of first choice, followed by topiramate. Deep brain stimulation of the Vim nucleus of the thalamus is a proven treatment option in severely affected patients.
