   What is Tremor?

  By Dr. Septian Rahadi, SpN  

Tremor is an involuntary, rhythmic shaking movement that occurs repeatedly without being noticed and appears in one or more limbs. More often, tremors appear in the hands, but this condition can also appear in other parts of the body, such as the legs and even the head. Tremors can occur occasionally or continuously. 

While not always indicative of a dangerous condition, tremors in some cases can be a sign of other health problems. Therefore, when tremors occur repeatedly and interfere with activities, a medical examination should be done immediately.

    Types of Tremor

Tremor has several types, including:

•     Essential Tremor:   The most common type of tremor. It usually appears in the area of the hands, head, voice, tongue, legs, and body.
•     Parkinsonian Tremor:   A condition that is one of the symptoms of Parkinson's disease. It usually appears in the area of the hands at rest, chin, lips, face, and legs.
•     Dystonic Tremor:   A symptom that occurs in dystonia (a movement disorder that occurs due to muscle contractions). This can occur in all muscles of the body.

    Causes of Tremor

Tremor occurs due to changes in the part of the brain that is responsible for regulating muscle movement. This change then causes muscle contractions and causes shaking. 

In addition, several health problems can also be the cause of tremor, such as:

•   Head injury
•   Multiple sclerosis (a disorder that occurs in the nerves of the brain, eyes, and spine)
•   Hyperthyroidism (a disease that occurs due to high levels of thyroid hormone in the body)
•   Parkinson's disease (a nervous system disease that reduces the body's ability to control movement and balance)
•   Stroke (a disease that occurs due to a decrease in blood supply to the brain)

It is important to note that stress and anxiety can also trigger tremors. When someone feels nervous or anxious, the sympathetic nervous system is active in their body.

    Tremor Prevention

Here are some steps that can be taken to prevent tremors:

1. Avoid triggers
2. Eat healthy foods
3. Exercise regularly
4. Manage stress
5. Get enough sleep
6. Limit alcohol consumption
