Abstract

Tremor is a rhythmic movement disorder and this characteristic differentiates it from other hyperkinetic movement disorders such as tics, myoclonus, fast dystonia and chorea. Underlying causes may be physiological, medical or neurological. Origin may be central or peripheral. This is the commonest movement disorders in the community and there are several varieties of tremors having distinct sites of origin, for example, rest tremor is typical of extrapyramidal system due to nigrostriatal dysfunction, action tremor indicative of brainstem origin and intention tremor suggestive of cerebellar origin. A clinician has to differentiate them and look for the underlying etiology. Though there are various pharmaceutical agents, tremor of neurological causes are often resistant and may need surgical intervention. There are some ‘odd’ tremors which are not typical of classical tremor and yet to be definitely categorized.
