Tremors occur from contractions of different, often opposing, muscle groups.
These contractions are involuntary and difficult to control. The exact cause of essential tremor is not known, however therapies exist that target various areas of the brain as the source of the tremor. Essential tremors usually involve the hands, head and arms. The tremor usually does not occur at rest. Emotion, exercise and fatigue can make an essential tremor worse.
