Tremor refers to an involuntary movement due to a lack of control over muscle contractions. The contractions start in a particular area and then spread throughout the body in most cases. Tremors are usually benign, not caused by a severe medical condition. However, they can be a sign of a more severe problem in some cases. While tremors are usually associated with Parkinson’s disease, the term also covers many other conditions resulting in muscle movements, such as multiple sclerosis or essential tremor. If you experience tremors more frequently than usual, you may need to schedule an appointment with a San Jose tremor specialist for proper diagnosis and treatment. This article looks at the different types of tremors and their possible causes.

Essential Tremors
Essential tremors are the most common type of tremor. They may affect any part of the body but are most often seen in the hands. Most essential tremors are caused by a problem with the brain’s cerebellum. This part of the brain helps to control movement and balance.
Essential tremors usually start gradually and get worse over time. While they can interfere with daily activities, essential tremors are not life-threatening. There is no known cure for essential tremors, but several treatments can help lessen the symptoms. While there is no cure for essential tremors, many treatments can help reduce the symptoms. These include medications, surgery, and lifestyle changes.

Parkinsonian Tremors
Parkinsonian tremors are caused by a problem with the brain’s dopamine system. Dopamine is a chemical that helps to control movement. When there is not enough dopamine, the muscles can become stiff and shake. Parkinsonian tremors usually start gradually and get worse over time. They are most common in the hands but can affect other body parts. There is no cure for Parkinsonian tremors, but several treatments can help lessen the symptoms. These include medications and lifestyle changes such as eating healthier and becoming more physically active.

Dystonic Tremors
A problem with the muscles causes dystonic tremors. They can occur anywhere in the body but are most common in the hands, neck, and face. Dystonic tremors usually start gradually and get worse over time. They can interfere with daily activities but are not life-threatening. There is no known cure for dystonic tremors, but several treatments can help lessen the symptoms. These include medications and surgery.
-
Cerebellar Tremors
Cerebellar tremors are caused by a problem with the cerebellum, the part of the brain that helps to control movement and balance. Cerebellar tremors usually start abruptly and get worse over time. They are most common in the hands but can affect other body parts. There is no known cure for cerebellar tremors, but several treatments can help lessen the symptoms. These include medications and surgery.
In summary, tremors are involuntary movements due to a lack of control over muscle contractions. The most common tremors include essential tremors that result from issues affecting the cerebellum. Parkinsonian tremors are caused by issues with the brain’s dopamine system, while dystonic tremors occur due to muscle problems. A problem with the cerebellum causes cerebellar tremors.
