Chronic vs. Occasional Tremors

Dealing with tremors is frustrating. You may feel as if you have no control when the tremors start or over how you can stop them. Tremors can occur chronically or occasionally, but regardless of how often they happen, tremors can seriously disrupt your day to day life. If you’re fed up with waking up every morning not knowing how bad your tremors will be that day, it’s time to seek treatment. Identifying the type of tremor you have is the key to getting the right treatment.

In this article, we will be discussing what a tremor is, the difference between chronic tremors and occasional tremors, how tremors are treated, and more. Tremors make performing your daily tasks more difficult, so it’s important to take the time to find the proper solution.


What is Tremor?

Tremor is a neurological disorder that causes involuntary and rhythmic shaking. It’s the most common movement disorder in the United States. Tremors are not life-threatening, but can seriously impact a person’s quality of life. The involuntary shaking of tremors can make it difficult for a person to do certain tasks, like drinking from a cup, using utensils, or writing. Tremors can happen in any part of the body, but it’s most common in the hands. They can also occur in your arms, head, vocal cords, and legs. Tremors can either be intermittent, meaning they happen at separate times with breaks in between, or constant. It can also happen sporadically or as a result of a disorder.

There are different types of tremor, such as essential tremor, Parkinsonian tremor, and dystonic tremor.

Essential Tremor

Essential tremor causes involuntary, rhythmic shaking which can affect the hands, head, torso, and legs. Essential tremor is also referred to as postural or action tremor. A postural tremor occurs when someone holds a position against gravity, such as holding their arm or leg outstretched. An action tremor occurs with the voluntary movement of a muscle.

Parkinsonian Tremor

Parkinsonian tremor is a common manifestation of Parkinson’s disease. Essential tremor can often be confused with Parkinson’s disease, but there are a few key differences. Those with Parkinson’s disease may experience resting tremor or action tremor, in addition to numerous other health problems such as poor balance and stooped posture. A resting tremor occurs when a part of the body is at rest, like when your hands are resting on your lap. The rhythmic tremor of Parkinson’s disease usually starts on one foot, leg, or hand, and can eventually affect both sides. The resting tremor that is often associated with Parkinson’s disease can also affect the jaw, chin, mouth, and tongue. Those with Parkinson’s disease may also experience an internal tremor.

Dystonic Tremor

Dystonia is a movement disorder that causes your muscles to contract involuntarily. This can cause repetitive or twisting movements of your body. Dystonia can impact one part of your body, two or more adjacent parts of your body, or all parts of your body. Dystonic tremor can range from mild to severe and can impact a person’s quality of life. Dystonia tremor usually affects the neck, eyelids, jaw, voice box, and hands.

Chronic Tremors

Essential tremor, Parkinsonian tremor, and dystonic tremor all cause chronic tremor. Chronic tremor is persistent and can be detrimental to a myriad of daily activities, such as eating, drinking, and writing. Living with chronic essential tremor is exhausting, which is why it’s crucial to find the correct treatment.

Occasional Tremors

An occasional tremor differs from a chronic tremor in that it happens sporadically. It’s common to have an occasional tremor, especially with age. An occasional tremor can occur if you’re stressed, angry, or anxious, after drinking caffeine, or if you’re very hot or cold. It’s common to have occasional hand tremors, but a tremor can also impact your feet, jaw, and chin. It’s important to pay attention to your tremor to see if the condition worsens over time. If your tremor begins to impact your daily tasks, it may be an indication of something more severe.

You should see your doctor if your tremor gets worse over time or if it starts to affect your daily life. Certain medications can cause occasional tremor, so your doctor will want to make sure the tremor is not caused by another condition.

There are certain lifestyle changes you can make to cope with occasional tremors. A mild tremor, like occasional hand tremors, typically does not require any treatment. But that doesn’t mean there aren’t other ways you can cope with it. To cope with occasional tremor, you can try physical therapy to improve your muscle control and strength. Another lifestyle change you can make is reducing your caffeine intake, as caffeine can sometimes cause or worsen a tremor.

Chronic vs. Occasional Tremors

Before seeking medical attention for a tremor, it’s important to know the difference between chronic and occasional tremors. The type of tremor you have will impact your course of treatment.

Chronic tremors are persistent and impact your everyday life. Chronic tremors make it difficult to perform daily functions, like drinking water, drawing, and writing.

Occasional tremors happen intermittently and will come and go. Occasional tremors typically do not require medical treatment as they are very common, especially with age and certain lifestyle factors. However, if an occasional tremor worsens over time, then you should see a doctor.

How are tremors diagnosed?

While a tremor is not considered a life-threatening condition, it is important to have a tremor diagnosis to make sure it’s not a symptom of something more serious. A tremor is diagnosed based on physical and neurological examination, as well as a person’s medical history. A doctor will assess the tremor according to a few factors, including:

  • If the tremor happens when hands are at rest or in action
  • The appearance of the tremor, including frequency and amplitude
  • The location of the tremor and if it occurs on one side or both sides

A doctor will also complete a series of other examinations, such as a neurological exam, a laboratory test, and a performance test. A neurological exam will check a patient’s tendon reflexes, posture and coordination, muscle strength and tone, gait, and ability to feel certain sensations. A doctor may also do a blood or urine test to see if the tremor is caused by thyroid malfunction, certain medications, or metabolic problems. Diagnostic imaging may also be completed to see if the tremor is caused by damage in the brain. A doctor may ask a patient to perform various tasks, such as drawing a spiral or drinking from a glass, to gauge the severity of the tremor. All of these tests may be necessary in order to find out the cause of the tremor. Tests can also indicate if the tremor is a result of drug or alcohol usage.

How are tremors treated?

Now that you know what a tremor diagnosis entails, let’s discuss how tremors are treated. There are various treatment options for tremors, such as:


There are certain medications that are often used to treat tremors. Beta-blockers are used to treat high-blood pressure and blood disease, but they have also been found to reduce tremors. Tranquilizers can help to reduce tremors that are caused by anxiety. Anti-seizure medication can also help those with tremors. The medication you take will ultimately depend on the type and severity of your tremor.

Botox injections

Botox injections have been found to help reduce certain types of tremors, especially tremors in the face and head. These botox injections typically last for up to three months.

Physical therapy

Physical therapy can reduce tremors by improving your muscle strength, control, and coordination. Your physical therapist may suggest using heavier glasses, wrist weights, and heavier writing tools in order to reduce the effect of tremors on your daily activities.

Deep Brain Stimulation and Focused Ultrasound

In addition to the treatments listed above, there are also several other essential tremor procedures to consider, the two most common being Deep Brain Stimulation and Focused Ultrasound.

If medication and physical therapy doesn’t seem to help your tremors, you may want to consider surgery. Deep Brain Stimulation (DBS) is the most common type of surgery for essential tremor. During this surgery, a doctor will insert electrodes into the area of your brain that’s responsible for the tremors. A wire from the electrodes will then go into your chest and send pulses to the electrodes to stop the brain from producing tremors.

Focused Ultrasound is another example of treatment for essential tremor. During this procedure, highly focused ultrasound is used to destroy the small portion of brain tissue that generates the tremor. Healing is usually quick and painless for most people because the procedure does not involve incisions.
