an involuntary and repetitive shaking of a body part. An
essential tremor is a neurological disorder characterized by
tremors without a noticeable
cause.

- A tremor is the only symptom
- The essential tremor only occurs during activity (action tremor)
- The tremor of Parkinson's Disease can occur at any time (both action tremor and resting tremor)
- Tremors occur most frequently in the hands. It can also affect the arms, head and voice.
- Essential tremors rarely involve the legs or feet.
- Tremors disappear when resting or during sleep and are aggravated with emotional stress or caffeine

on the patient's history, and an examination that reveal
tremors upon voluntary movements.

It is the
most common type of "shaking disorder." Symptoms may occur
in the teenage or early adult years. Although the cause is
not known, almost half of the cases are hereditary. Since it
does not cause serious disabilities or complications, it is
called a "familial" or "benign"
tremor.

There is no definite cure. If the tremor interferes with the daily activities or it worsens under certain circumstances, medications can be helpful. Be sure to consult your physician because not all the patients benefit from such drugs.
