What is Tremor?

Tremor is an involuntary, rhythmic shaking that occurs in one or more parts of the body. It most commonly affects the hands, head, voice, and legs. Not all tremor types are caused by the same reason; accurate diagnosis is decisive in treatment selection.

Essential tremor is the most common type of tremor. In this type, which occurs during movement (action tremor) and usually has a family history, although the risk of Parkinson's disease is somewhat increased, essential tremor is a separate condition. Parkinson's tremor is seen at rest and is accompanied by progressively increasing motor slowness.

Hyperthyroidism, excessive caffeine, certain drugs (bronchodilators, lithium, valproate), and alcohol withdrawal can also lead to tremor. These physiological and drug-induced tremor types may resolve when the underlying factor is corrected.

Symptoms

Rhythmic shaking in the hands, head, or voice
Difficulty with fine tasks such as eating or writing
Tremor during rest or during movement (differs according to type)
Increased tremors with stress, fatigue, and caffeine
Tremor prominent in certain positions (when extending arms) (essential tremor)
Progressively worsening tremor

Risk Factors

Family history of tremor (for essential tremor)
Advanced age
Parkinson's disease
Hyperthyroidism or thyroid diseases
Excessive caffeine or alcohol consumption
Certain drugs (valproate, lithium, amiodarone)

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • If tremor restricts daily activities
  • If resting tremor and slowing with movement are together (suspected Parkinson's)
  • If thyroid disease or drug-induced cause is suspected
  • If tremor is rapidly progressing
  • If other neurological symptoms also accompany

Treatment Methods

01
Essential tremor: propranolol or primidone (first-line drugs)
02
Parkinson's tremor: dopaminergic therapy
03
Treatment of the underlying cause (thyroid, medication adjustment)
04
Deep brain stimulation (DBS) — severe tremor not controlled with medication
05
Focused ultrasound thalamotomy (non-invasive surgical option)
06
Occupational therapy and use of adaptive equipment
