Although the problem is usually not dangerous, tremors get worse over time and can be severe in some people. It is not caused by other diseases, although it is sometimes confused with Parkinson's disease.


Tremor is a disorder of the nervous system that causes rhythmic shaking. Tremor can affect almost any part of the body, but tremor occurs most often in the hands - especially when trying to do simple tasks, such as drinking a glass of water, tying shoelaces, writing, or shaving the beard. Tremor can also affect the head, voice, arms, or legs.

Although the problem is usually not dangerous, tremors get worse over time and can be severe in some people. It is not caused by other diseases, although it is sometimes confused with Parkinson's disease. Tremor can occur at any age but is most common in older adults.


Overview of the signs and symptoms of tremors

Start gradually.

Worse with time.

Usually occurs first hand, affecting one or both hands.

May (or may not) include head movement.

It is aggravated by emotional stress, fatigue, caffeine use, or hot or cold temperatures.

Tremor versus Parkinson's disease

Many people associate tremors with Parkinson's disease, but the two problems are different:

When tremors occur. Hand tremor often occurs when using the hand. Tremor due to Parkinson's disease is most prominent when the hand is at rest.

Related conditions. Tremor does not cause other health problems, while Parkinson's disease is associated with stooped posture, slow movements, and a disturbed gait. However, people with tremors can sometimes develop neurological signs and symptoms - like an unsteady gait.

Parts of the body are affected. Tremor can involve the hands, head, voice, and legs. The tremors caused by Parkinson's disease usually affect the hands and do not manifest in the head or voice.


About half of tremors occur because of a genetic mutation. This is called familial tremor. Other causes of tremors in people who do not have the genetic mutation and no causes have been found.

Risk factors

There are two known risk factors:

Gene Mutation. The genetic diversity of tremor is autosomal dominant, meaning that a defective gene is passed on from one parent. If you have a parent with a genetic mutation that causes tremor, there is a 50 percent chance of developing the disorder.

Age. Tremor is more common in middle age and older age.


Tremors are not life-threatening, but symptoms often get worse over time. If tremors become severe, it can be difficult to:

Holds a cup or glass without spilling.

Eat normally.

Make-up or shave.

Speaking: In case mouth or tongue is affected.

Writing - handwriting can become increasingly large, shaky, and difficult to read.

Tests and diagnostics

There is no specific test for tremors. Determining the diagnosis is often a matter of among other problems that can cause symptoms. To do this, your doctor may suggest the following:

Neurological examination

Nervous system function tests, including checking:

Tendon reflex.

Muscle strength.

The ability to perceive certain sensations.

Posture and coordination.

How to go.


Blood and urine tests may be done for problems such as:

Thyroid disease.

Side effects of drugs.

Do a test

To assess the tremor may be required:

Drink a glass.

Keep arms outstretched.


Draw a spiral.

Treatments and drugs

Some people with tremors may not need treatment if symptoms are mild. But if tremors make it difficult to work or perform daily activities, treatment options can be discussed with your doctor.


Beta-blockers. Commonly used to treat high blood pressure, beta-blockers such as propranolol, atenolol, metoprolol, and nadolol help reduce tremors in some people. May not be selected if you have certain asthma, diabetes, or heart conditions.

Antiepileptic drugs. Epilepsy medications including primidone, gabapentin, and topiramate may be effective in people who do not respond to beta-blockers. The main side effects are drowsiness and flu-like symptoms, which usually go away in a short time.

Sedative. Doctors sometimes use medications like diazepam and alprazolam to treat people whose tremors are made worse by stress or anxiety. Side effects may include confusion and memory loss. Also, these medications should be used with care because they can be habit-forming.

OnabotulinumtoxinA (Botox) injection. Botox treats wrinkles on the face, but it can also be helpful in treating certain types of tremors, especially those with symptoms in the head and voice. Botox can improve problems when prescribed every three months. But if it is used to treat hand tremors, it can sometimes cause finger weakness.


Physical therapy exercises can sometimes reduce tremors and improve muscle coordination and control. Occupational therapists may recommend certain devices to reduce the effects of tremors on daily activities.


Surgery may be an option for people with tremors that do not respond to medication. This type of surgery is known as deep brain stimulation.

Deep brain stimulation involves inserting an electrical probe into the thalamus, the part of the brain responsible for causing tremors. The device transmits painless electrical impulses that interrupt signals from the thalamus that can cause tremors.

Side effects of surgery may include problems with motor control or speech, balance problems, and temporary or permanent cognitive impairment, such as learning difficulties, or problems with vision. However, deep brain stimulation is very effective for severe tremors and these side effects are rare.

Lifestyle and remedies

The following suggestions can sometimes help reduce or reduce tremors:

Avoid caffeine. Caffeine can make the body produce more adrenaline, which can make tremors worse. Avoid other stimulants as well.

Use alcohol sparingly. Some people find that their tremor improves slightly after they drink alcohol, but drinking is not a good solution for people with tremors. Because tremors tend to worsen when the effects of alcohol wear off. Finally, more alcohol consumption is needed to reduce tremors, which can lead to chronic alcoholism. If tremors occur, it is best to drink little or nothing.

Learn to relax. Stress tends to make tremors worse, and a state of regular relaxation improves them. While it is not possible to eliminate all stress from life, it is possible to change the way you react to stressful situations by using a variety of relaxation techniques. Many people also find that exercise such as walking, swimming, jogging, or biking is a great stress reliever.

Rested. Fatigue can worsen tremors. Try to get at least seven hours of sleep each night. If you have trouble falling asleep, wake up many times, or wake up early and can't go back to sleep, talk to your doctor.

Alternative medicine

Although there are no scientific studies confirming the benefits of surrogates for people with tremor, the following treatments may be helpful:

Acupuncture. This treatment involves inserting needles in the skin at several points on the body. It is used to relieve symptoms of a variety of problems.

Hypnosis. This involves being put into a state of lethargy, in which intense concentration is required. Hypnosis is indicated to help control certain behaviors or to deal with a variety of medical problems.

Massage. This involves manipulating muscles, tendons, and ligaments to help relieve tension.

Biofeedback. This technique uses electrical sensors to help use the mind to control body functions.

Coping and supporting

For many people, tremors can have serious social and psychological consequences. If the effects of a concussion make it difficult to live fully as you once did, consider joining a support group for people with the disorder.

Support groups are not for everyone, may find it helpful to have encouragement from those who understand what they are going through. Or you might consider seeing a counselor or social worker who can help meet the challenges of living with tremors.
