When to seek care for tremor

Overview

A tremor is an unintentional, rhythmic shaking movement in a part of your body, most often your hands. It can also affect your arms, head, voice, or legs. Tremors can happen when you are moving or when you are at rest.

Yes, tremor is a very common symptom that affects people of all ages. It becomes more common as you get older.

Tremor can affect anyone, but it is most often seen in older adults. Certain types, like essential tremor, often run in families.

Symptoms

Common symptoms

• Rhythmic shaking in your hands or fingers that may be worse when trying to do a task, like writing or holding a cup.
• Tremor in your arms, head, voice, or legs.
• Shaking that stops when you are resting and gets worse with movement (essential tremor).
• Shaking that happens at rest and lessens with movement (Parkinsonian tremor).

Symptoms in children

• Children can have tremors, often related to stress, fatigue, or certain medications.
• A tremor that appears suddenly after a head injury or with other symptoms like headache or vomiting needs urgent medical attention.

Symptoms in older adults

• Essential tremor is the most common cause of tremor in older adults, often affecting the hands when doing tasks.
• Tremor at rest, along with stiffness or slowness, may suggest Parkinson's disease.
• Medication side effects or metabolic problems can also cause tremor in older people.

Causes

Main causes

• Essential tremor – the most common cause, often runs in families.
• Parkinson's disease – a progressive neurological condition.
• Medication side effects (for example, some asthma drugs or antidepressants).
• Stress, anxiety, or fatigue.
• Caffeine or other stimulants.
• Overactive thyroid (hyperthyroidism).
• Alcohol withdrawal.

Risk factors

• Age – tremor becomes more common as you get older.
• Family history of essential tremor.
• Having certain conditions like multiple sclerosis or Parkinson's disease.
• Use of certain medications or substances.

When to see a doctor

See a doctor urgently if:

• Seek urgent care if you have a sudden tremor with weakness, numbness, confusion, or trouble speaking.
• See a doctor the same day if your tremor is getting worse quickly or interfering with daily activities like walking, eating, or writing.

Book a routine appointment if:

• Make a routine appointment if you have a mild tremor that has been present for a while and is not getting worse.
• See your doctor if the tremor bothers you or makes it hard to do everyday tasks.

Diagnosis

Your doctor will ask about your medical history, family history, and when the tremor happens. They will examine you to see how the tremor affects your movements.

Tests that may be done

• Blood tests to check for thyroid problems or other metabolic issues.
• Neurological exam to assess coordination, balance, and muscle tone.
• Imaging tests like an MRI or CT scan of the brain, if needed.
• Sometimes an electromyography (EMG) to measure muscle activity.

What to expect at your appointment

Your doctor will work with you to find the cause of the tremor. They may refer you to a neurologist (a doctor who specializes in the nervous system) for further evaluation. Most tremors can be managed well with the right care.

Treatment

Treatment for tremor depends on the cause and how much it affects your life. For many people, lifestyle changes are enough. If the tremor is due to an underlying condition, treating that condition often helps.

Self-care at home

• Reduce caffeine, alcohol, and other stimulants.
• Get enough sleep and manage stress through relaxation techniques.
• Avoid activities that worsen the tremor when possible.
• If the tremor is from anxiety, therapy or counselling may help.

Medical treatments

If lifestyle changes are not enough, your doctor may recommend medications to help control the tremor. These might include beta-blockers (often used for essential tremor) or medications that affect brain chemicals. Botulinum toxin injections can help tremors in the head or voice. Your doctor will discuss the options that are right for you, taking into account side effects and other health conditions.

When is surgery considered?

In rare, severe cases that do not respond to medication, a surgical procedure called deep brain stimulation (DBS) may be considered. This involves implanting electrodes in the brain to regulate abnormal signals. It is only for very specific types of tremor.

Living with this condition

A tremor can make daily tasks like writing, eating, or dressing more challenging. Occupational therapists can suggest tools and strategies to make these activities easier. Using heavier utensils or weighted cups can help reduce shaking.

Lifestyle tips

• Use adaptive devices like weighted pens or stabilising kitchen tools.
• Practice relaxation techniques to reduce stress-related shaking.
• Stay physically active to maintain muscle strength and coordination.
• Avoid triggers like fatigue, caffeine, or extreme temperatures.

Diet and exercise

A healthy diet rich in fruits, vegetables, and whole grains supports overall wellbeing. Regular exercise, such as walking or swimming, can improve balance and reduce stress. If alcohol triggers your tremor, it's best to avoid it. Talk to your doctor about any supplements, as some can make tremors worse.

Mental health and emotional wellbeing

Living with a tremor can sometimes lead to embarrassment, frustration, or social anxiety. It's important to acknowledge these feelings and seek support. Talking to a counsellor or joining a support group can help you cope.

Prevention

Many types of tremor cannot be prevented, especially those that run in families. However, you may reduce your risk of tremor from lifestyle causes by managing stress, limiting caffeine and alcohol, and avoiding certain medications that can trigger shaking.

Complications

If left untreated

• Difficulty performing daily activities like eating, writing, or dressing.
• Social withdrawal or depression due to embarrassment.
• In some conditions, tremor can worsen and lead to falls or injuries.

Long-term outlook

Most tremors are not dangerous and can be managed well with the right support. Many people with tremor live full, active lives. If an underlying condition is causing the tremor, early treatment can improve symptoms and quality of life. Your healthcare team will work with you to find the best approach.
