title: [Tremors].
abstract: In this general review of tremors, one must distinguish the parkinsonian rest tremor, which concerns relaxed muscles, from other tremors that accompany muscle activities, such as maintaining a posture or executing a movement. Among various postural and action tremors, essential tremor occupies first place, in terms of its prevalence. The diagnosis of essential tremor is based on precise criteria. Often hereditarily transmitted, essential tremor can sometimes be quite disabling. Essential tremor and parkinsonian tremor are compared on an accompanying table. Other types of tremor are reviewed according to their possible prevalences. i.e. iatrogenic tremor and dystonic tremor. Particular attention is paid to orthostatic tremor, multiple sclerosis tremor and psychogenic tremor.
