Americans are estimated to have essential tremor
Understanding Essential Tremor
Essential Tremor (ET) is a neurological movement disorder that causes involuntary, rhythmic shaking. It most often affects the hands and arms and is usually most noticeable while a person is using their hands, such as when eating, drinking, writing, or holding an object. The head or voice may also be affected. Although ET is one of the most common movement disorders, its impact can be overlooked, underestimated, or mistaken for a normal part of aging.
ET can begin at any age and may gradually become more noticeable or disruptive over time, although the rate of progression varies. Everyday activities can become difficult. The effects of ET can extend beyond the tremor itself, affecting independence, social interactions, emotional well-being, and quality of life.
Common Symptoms
- Shaking of the hands or arms when using them or holding them in a position, such as with the arms outstretched.
- Difficulty performing everyday activities that require precise hand movements
- Shaking in the head or voice in some individuals
FAQs
What causes ET?
The exact cause of ET is not fully understood, but researchers believe it involves changes in the brain circuits responsible for controlling movement. In many cases, ET can run in families, suggesting that genetics may play a role. Researchers continue to study the biology underlying ET to better understand the condition.
Is ET a progressive condition?
ET is generally considered a progressive condition, meaning that the tremor may gradually become more noticeable or disruptive over time. However, the rate and pattern of progression can vary considerably. Some people experience mild symptoms for many years, while others may find that tremors increasingly affect daily activities such as writing, eating, drinking, or getting dressed.
Is ET the same as Parkinson’s disease?
No. ET and Parkinson’s disease are different neurological conditions, although both can cause tremor. ET most often causes shaking while a person is using their hands, such as when lifting a cup or writing. Parkinson’s disease commonly causes tremor when the affected body part is at rest and is also associated with other symptoms, including slowed movement and stiffness. Because symptoms can sometimes overlap, a healthcare professional should evaluate a new or changing tremor.
Who develops ET?
ET can affect people of all ages, but it becomes increasingly common with age.
Can ET run in families?
Yes. ET often occurs in families, suggesting that genetics can play an important role. However, many people with ET do not have a known family history, and no single genetic cause has been identified for most cases.
How is ET diagnosed?
There is no single test used to diagnose ET. Healthcare providers typically diagnose the condition based on a person’s symptoms, medical and family history, and neurological examination. In some cases, additional tests may be performed to help rule out other possible causes of tremor.
How is ET managed?
Management depends on how much the tremor affects a person’s daily life. Some people with mild symptoms may not need treatment. Options may include medications, occupational or physical therapy, adaptive tools, nerve-stimulation devices, and procedures for selected individuals. A healthcare professional can help you choose an approach based on your symptoms, health, and goals.
When should I talk to a healthcare professional?
Talk with a healthcare professional if you develop a new tremor, your tremor changes, or it affects everyday activities or quality of life. If treatment is not helping enough or is causing side effects, ask about reviewing your treatment plan.
