tremor procedure preparation

Overview

A tremor is a rhythmic, involuntary shaking of a body part, most often your hands. It happens because the brain and nerves that control muscles are not sending the right signals. For some people, a tremor can be mild, but for others it can make everyday tasks like drinking from a cup or writing very hard. When medicine doesn't help enough, a doctor may recommend a procedure to calm the tremor. This article explains what to know and how to prepare for such a procedure.

Yes, tremor is quite common. Many people experience a slight shaking, especially as they get older. The most common type, essential tremor, affects about 1 in 25 adults over age 40, and it becomes more frequent with age.

Tremor can affect people of any age, but it is most often seen in middle-aged and older adults. It affects men and women, and some types run in families. If you have a close relative with essential tremor, your chance of developing it is higher.

Symptoms

Common symptoms

• Shaking in the hands or arms, often when trying to hold objects or perform actions
• A rhythmic back-and-forth movement of the head, jaw, voice, or legs
• Difficulty writing, drawing, or using a spoon or cup
• The shaking may stop while you are at rest, or it may get worse when you try to move
• In some cases, the tremor is mild and only noticeable during stress or after caffeine

Causes

Main causes

• Essential tremor, a neurological condition that often runs in families
• Parkinson's disease, where the brain's movement control is affected
• Medication side effects or drug interactions
• Thyroid problems, such as an overactive thyroid
• Multiple sclerosis or other conditions that damage nerves
• Stress, fatigue, caffeine, or low blood sugar

Risk factors

• Getting older
• Having a family history of essential tremor
• Long-term stress or exhaustion
• Taking certain medications that can cause tremor
• Heavy alcohol use or withdrawal

When to see a doctor

See a doctor urgently if:

• If your tremor comes on suddenly and is joined by severe headache, weakness, trouble speaking, confusion, or vision changes, get emergency help right away.
• If you are having trouble breathing or swallowing, call your local emergency number.

Book a routine appointment if:

• Make a doctor's appointment if your tremor is new, getting worse, or interfering with your daily activities.
• You should also see a doctor if you are concerned about the tremor or if you have a family history of tremor or Parkinson's disease.

Diagnosis

To diagnose a tremor, your doctor will start by asking about your health history and family history. They will perform a physical exam and ask you to do tasks like touching your finger to your nose, holding a cup, or drawing a spiral. This helps show what kind of tremor you have. If needed, your doctor may order tests to rule out other conditions.

Tests that may be done

• Neurological examination – a series of simple tasks to see how your muscles and nerves work
• Blood tests – to check for thyroid problems, blood sugar levels, or other causes
• Brain imaging such as an MRI or CT scan – to create detailed pictures of your brain
• In some cases, a dopamine transporter scan (DAT) to help tell apart different types of tremor

What to expect at your appointment

Your doctor may refer you to a neurologist, a doctor who specialises in brain and nerve conditions. During the visit, bring a list of medicines you take, including vitamins and supplements, and any notes about when the tremor started and when it happens. If you are being evaluated for a procedure, you may need additional appointments with a neurosurgeon, an occupational therapist, and an anaesthesiologist to plan your care.

Treatment

Treatment for tremor depends on the cause, how much it affects your life, and your personal health. There is no one-size-fits-all approach. Your doctor will work with you to decide whether self-care, medicines, or a procedure is the best option. The goal is always to improve your quality of life and keep you as safe and independent as possible.

Self-care at home

• Limit caffeine and alcohol, as they can make tremor worse for many people.
• Try stress management tools like deep breathing, meditation, or talking with a friend.
• Get enough sleep and rest – exhaustion can increase shaking.
• Use adaptive tools like weighted cups, special pens, or button hooks to make daily tasks easier.
• Work with an occupational therapist to find changes that help with eating, writing, and dressing.

Medical treatments

Medicines are often tried before any procedure is considered. There are several different types of medicine that can help reduce tremor, but they don't work for everyone, and they can have side effects. Your doctor will explain the options and help you weigh the benefits and risks. You should never change or stop any medicine without consulting your doctor. If you and your doctor decide that a procedure is right for you, the preparation usually involves several steps. Your care team will give you detailed instructions. You may need to have blood tests, an ECG (heart check), and imaging scans of your brain. You will meet with a neurologist, a brain surgeon, and sometimes an anaesthesiologist. You may need to stop taking certain medicines days before the procedure, and you will be told not to eat or drink for several hours before you arrive at the hospital. You will also need to arrange for someone to drive you home and stay with you for the first day or two. Your team will guide you through every step, so ask any questions that come up.

When is surgery considered?

For people with severe tremor that hasn't improved with other treatments, surgery may be an option. Deep brain stimulation (DBS) is a procedure where a small device is placed in the brain to send electrical signals that help control movement. Another option is focused ultrasound, which uses sound waves to target the tiny brain area causing the tremor. These procedures have helped many people, but they come with risks, so a specialist team will carefully assess whether you are a good candidate.

Living with this condition

Living with a tremor can be challenging, but small changes can make a big difference. Use a heavier cup or bowl so it shakes less, and drink with two hands if needed. Write in print instead of cursive, or use a keyboard. Practice slowing down and focusing on one task at a time. After a procedure, your recovery will be gradual, and you may need to explore your home for safety – for example, removing loose rugs to prevent falls.

Lifestyle tips

• Build a regular daily routine with set sleep and meal times.
• Find an activity you enjoy that helps you relax, like listening to music or gardening.
• Stay connected with friends and family, and let them know how they can support you.
• If you drink alcohol, talk to your doctor about whether it is safe for you, as alcohol can interact with medicines and affect tremor.
• If you are having a procedure, follow your recovery instructions about rest, wound care, and activity limits.

Diet and exercise

A balanced, colourful diet gives your body fuel and supports your nervous system. Some people find that caffeine and sugar can make their tremor worse, so you might try cutting back and see if it helps. Regular movement such as walking, swimming, or Tai Chi can improve coordination and reduce stress. If you've had a procedure, ask your care team when you can safely start exercising again.

Mental health and emotional wellbeing

Tremor can affect more than just your body. It may make you feel self-conscious, frustrated, or isolated. It is normal to feel sad or anxious. Please remember that these feelings are not a failure on your part. Talk to your doctor about counselling or support groups. In an urgent emotional crisis, contact your local mental health helpline or go to the nearest emergency department.

Prevention

Most types of tremor cannot be prevented because they are linked to genetics, ageing, or conditions like Parkinson's disease. However, you can reduce your risk of tremor that is triggered by lifestyle factors. Limit alcohol, manage stress, get enough sleep, and avoid excessive caffeine. If you have an overactive thyroid or another treatable condition, following your treatment plan may help prevent tremor.

Complications

If left untreated

• Difficulty feeding or drinking, which can lead to poor nutrition or dehydration
• Falls and injuries from losing balance or grip
• Feeling embarrassed or withdrawn from social activities
• Difficulty at work, problems with writing, or using a keyboard
• Increased anxiety or depression

Long-term outlook

A tremor is often not a serious threat to your health, and many people manage very well. For those who need it, procedures can be life-changing, helping people go back to eating with a fork, writing, and enjoying their hobbies. Your healthcare team is there to support you and find the best path forward. With time and the right care, most people can find relief and maintain a good quality of life.
