What're the symptoms of tremors?

There are many types of tremor and several ways in which tremor is classified. The most common classification is by behavioral context or position. There are five categories of tremor within this classification: resting, postural, kinetic, task-specific, and hysterical. Intention tremors are slower types of tremors, so the movements look broader and coarse. Intention tremors can occur at rest, but usually increase with activity. Essential tremors, however, are fairly quick, small movements. Essential tremor most commonly affects the head and hands, but it may also affect other muscles. However, unless the tremor is very severe, the hands and arms usually do not shake when they are at rest. While essential tremors usually remain mild, they can be a source of embarrassment because they can affect the person's ability to write and eat. Essential tremors usually worsen when the person is stressed, tired, anxious, or affected by caffeine or other stimulants. Essential tremors can affect one side of the body more than the other, and may cause the voice to shake if they affect the vocal cords. The type of tremor that is common with Parkinson's disease is more severe, with as many as four to five muscle movements per second. Parkinsonian tremors occur at rest, but slow down or go away altogether when the person moves.
