Tremor is the rhythmic, oscillating shaking movement of the whole body or just a certain part of it, caused by problems of the neurons responsible from muscle action.

Tremor may occur as an isolated symptom and usually of idiopathic (unknown) cause (essential tremor) or a part of the symptom constellation of another disorder (e.g. Parkinson's disease). Tremors may occur at rest (Parkinson's disease), during voluntary movements (cerebellar lesions) or during excessive activity of muscles (essential tremor, hyperthyroidism). Usually, tremors involve the hands, but they may also involve the head, face, neck, voice and legs.

Types
There are several types of tremors. These include:

Rest tremor is a tremor that occurs despite the limb being fully supported and at rest. It usually progresses at the rate of 4-7 Hz (hertz), and is the typical Parkinsonian tremor, though it may also occur with an essential tremor.
Movement (action) tremor occurs when an individual tries to perform an action.
Postural tremor occurs when supporting a limb against gravity.

Causes
Tremors may increase with anxiety and caffeine and cease during sleep. Amongst the diseases associated with tremors, essential tremor and Parkinson's disease are the best known. Tremors can also occur due to large doses of ionizing radiation.

Treatment
Medications are used only if tremor interferes with daily life activities. Some of the drugs that can be used are clonazepam, primidone and propranolol.

Other tremors
Ocular tremors are eye tremors that are not problem tremors, but instead normal eye tremors believed to assist in vision. (Note: Larger eye movements called saccadic eye motion are not tremors.)
