11886 Essential Tremor

Overview

Essential tremor is a condition that causes parts of your body to shake rhythmically. It usually affects your hands and arms, but it can also affect your head, voice, or legs. It is not dangerous to your health, but it can make everyday tasks like eating, writing, or dressing harder.

Yes, it is fairly common. Studies suggest it affects about 1 in 100 people overall, and it becomes more common with age.

Essential tremor can begin at any age, but it is most often seen in middle-aged and older adults. Men and women are affected equally. If it runs in your family, you have a higher chance of developing it.

Symptoms

Common symptoms

• A rhythmic shaking in one or both hands, especially when holding things or reaching for something
• Shaking that gets worse with movement, stress, or fatigue
• Difficulty writing, drawing, or using tools
• Shakiness in the head that makes it look like a 'yes' or 'no' motion
• A shaky voice when speaking
• Tremor that improves after drinking a small amount of alcohol (though this is not a suggested treatment)

Symptoms in children

• In children, essential tremor may first appear as a subtle shaking of the hands during fine motor tasks like drawing, cutting, or using small objects
• It may be mistaken for nervousness or clumsiness
• Children with this condition may feel embarrassed, so it's important to be reassuring and seek professional advice

Symptoms in older adults

• Older adults may notice shaking that makes meals, dressing, or holding a cup more difficult
• Because other conditions become more common with age, a doctor's assessment is important to rule out other causes
• Tremor can increase feelings of frustration or social isolation if not addressed

Causes

Main causes

• The exact cause is not fully understood
• In many cases, it appears to be inherited from a parent (familial tremor)
• It is linked to abnormal communication in areas of the brain that control movement, but it is not caused by a psychiatric problem
• It is not caused by drug use, even though certain medicines can cause similar shaking

Risk factors

• A parent, brother, or sister with essential tremor
• Being over the age of 40
• High levels of stress or anxiety (which can make tremor more noticeable)
• Having a health condition that makes moving difficult, though this is not a direct cause

When to see a doctor

See a doctor urgently if:

• Go to urgent care or see a doctor the same day if your tremor suddenly gets much worse, or if it is accompanied by weakness, numbness, confusion, or a severe headache
• If you have a tremor and also experience dizziness, fainting, or a very fast heartbeat, seek care promptly

Book a routine appointment if:

• Make an appointment if you notice a tremor that is new, lasting, or interfering with daily tasks
• If your tremor is affecting your confidence, sleep, or ability to work, talk to a doctor
• If you have a family history and want to understand your risks

Diagnosis

A doctor will ask about your symptoms, do a physical exam, and watch you perform simple tasks like writing or holding out your hands. They will check to make sure other conditions are not causing the tremor.

Tests that may be done

• Blood tests to check for thyroid or metabolism problems
• Nerve tests, like electromyography (EMG), to see how your nerves and muscles work
• Imaging scans like an MRI or CT scan, if the doctor needs to look more closely at the brain
• A task-based test, like drawing a spiral or pouring water, to assess how the tremor affects you

What to expect at your appointment

The appointment usually takes about 30 to 60 minutes. The doctor will explain what they've found, discuss possible causes, and suggest next steps. You may be referred to a neurologist, a doctor who specialises in the nervous system, for further evaluation.

Treatment

Treatment depends on how much the tremor affects your life. Many people need no treatment at all. For others, a combination of simple lifestyle changes, occupational therapy, and medical treatment can make a big difference.

Self-care at home

• Avoid caffeine, energy drinks, and other stimulants, as they can make tremor worse
• Practice stress-reducing techniques like deep breathing, meditation, or gentle yoga
• Get enough sleep and rest, since tiredness can worsen shaking
• Use utensils with non-slip grips, heavier cups, or kitchen tools designed for shaky hands
• Try resting your shaking hand on a table when doing tasks
• Limit or avoid alcohol, because although it may temporarily reduce tremor, it can have harmful long-term effects

Medical treatments

Your doctor may suggest medication that works on the nervous system to reduce shaking. These are not cures, but they can make symptoms less noticeable. Some people benefit from therapies that focus on coordination and fine motor skills. It may take time to find the right approach for you.

When is surgery considered?

For people with very severe tremor that does not respond to other treatments, a procedure called deep brain stimulation (DBS) may be considered. This involves placing a tiny device in the brain to help control the shaking. It is only used after a thorough assessment by a specialist team.

Living with this condition

Living with essential tremor means finding your own ways to manage it. Simple strategies like using both hands, switching to button-down shirts, or using speech-to-text features on your phone can help you stay independent. It's important to keep doing the things you enjoy, even if you need to adapt them.

Lifestyle tips

• Use adaptive aids, like weighted spoons, pens with special grips, or button hooks
• Break tasks into smaller steps so you can rest between them
• Eat nutritious meals at regular times and stay well hydrated
• Stay socially active — explain your condition to friends so they understand
• Talk to an occupational therapist for practical tips tailored to your everyday life

Diet and exercise

There is no special diet that cures essential tremor, but eating a balanced diet and staying active supports your overall health. Regular physical activity like walking, swimming, or tai chi can improve strength and reduce stress. Some people find that cutting out caffeine helps their tremor feel less noticeable.

Mental health and emotional wellbeing

Dealing with a visible tremor can be frustrating or worrying. It may affect how you feel about yourself or how you interact with others. These feelings are normal, and you do not have to deal with them alone. Talking to a counsellor or joining a support group can be very helpful. If you're feeling anxious or low, please tell your doctor.

Prevention

There is no known way to prevent essential tremor, because doctors do not know exactly what causes it. However, you can take steps to reduce how much the tremor affects your daily life by managing stress, getting good sleep, and avoiding triggers.

Complications

If left untreated

• Difficulty eating and drinking without spills, which can lead to weight loss or dehydration
• Difficulty with personal care tasks like shaving, brushing teeth, or dressing
• Avoidance of social situations because of embarrassment
• Stress, frustration, or low self-esteem

Long-term outlook

Essential tremor is not dangerous or life-threatening. With the right support, many people continue to live full, active, and independent lives. It may take time to find strategies that work for you, but most symptoms can be managed well. You can expect to live a normal life span.
