This page will help answer your questions about hand tremors.
What Are Hand Tremors?
Hand tremors are involuntary, repetitive, and spontaneous movements. The tremor may be mild and occur naturally due to stress or excessive caffeine intake, or it may be severe and associated with medical conditions such as Parkinson’s disease or multiple sclerosis. Severe tremors can affect a person’s quality of life and interfere with daily tasks such as eating and drinking.
What Are the Causes of Hand Tremors?
- Advanced age.
- Excessive consumption of stimulants.
- Large amounts can irritate the nerves, leading to hand tremors.
- Stress and anxiety.
- Anxiety and stress increase the secretion of the hormone cortisol, which affects the nervous system and causes hand tremors.
- Changes in temperature.
- Side effects of certain medications.
- Health conditions such as:
- Parkinson’s disease.
- Hyperthyroidism.
- Liver failure.
- Multiple sclerosis.
- Paralysis agitans (another term for Parkinson’s disease).
- Huntington’s disease.
- Muscle strain.
- Brain injuries or strokes.
How to Manage Hand Tremors
- Often, no treatment is needed. However, if hand tremors worsen, consult a doctor to prescribe appropriate treatment.
Lifestyle modifications include:
- Quitting smoking.
- Reducing stimulant consumption.
- Managing anxiety and stress through:
- Physical exercises such as aerobic exercises (running, walking, swimming) and resistance exercises (weightlifting).
- A well-balanced, complete diet.
- Stress and anxiety control.
- Creating a financial management plan.
- Developing new hobbies.
- Cognitive behavioral therapy (CBT): a form of talk therapy that helps manage thoughts, feelings, and behaviors, and improve quality of life.
- If you suspect your medication is causing hand tremors, consult your doctor. Do not stop taking prescribed medication without medical advice.
- If the tremor is caused by a medical condition, follow your doctor’s instructions and prescribed treatments to reduce tremors.
When Should You See a Doctor?
See a doctor to ensure your health if:
- The tremor persists for several weeks.
- It affects your daily activities such as drinking or eating.
- Other symptoms accompany the tremor, such as excessive sweating or increased heart rate.
Frequently Asked Questions:
What is the difference between tremors caused by Parkinson’s disease and other causes?
- In Parkinson’s disease, hand tremors occur mostly at rest (when not using the hands) and decrease when using the affected part.
- In other causes, hand tremors occur mostly during use of the hands and decrease at rest.
What is the difference between physiological (normal) and pathological (disease-related) hand tremors?
Normal hand tremors occur due to stress, anxiety, low blood sugar, or excessive caffeine intake. Pathological hand tremors, on the other hand, are associated with certain diseases such as Parkinson’s disease, multiple sclerosis, stroke, brain injuries, or some genetic disorders.
Normal hand tremors are usually mild and barely noticeable. They tend to increase with movement or stress, disappear during rest or sleep, and generally do not affect daily activities. Pathological hand tremors are more noticeable, can occur during movement or at rest, and affect daily activities. They are often accompanied by slow movement, muscle stiffness, balance problems, or changes in speech.
Normal hand tremors do not require treatment but can be reduced by lifestyle changes such as reducing caffeine intake, practicing relaxation techniques, and getting enough sleep. Pathological hand tremors, however, require treating or managing the underlying disease with medications.
