Tremor is an unintentional, rhythmic muscle movement involving to-and-fro movements (oscillations) of one or more parts of the body. It is the most common of all involuntary movements and can affect the hands, arms, head, face, voice, trunk, and legs. Most tumors occur in the hands. In some people, tremor is a symptom of a neurological disorder or appears as a side effect of certain drugs. The most common form of tremor, however, occurs in otherwise largely healthy people. Although tremor is not life-threatening, it can be embarrassing to some people and make it harder to perform daily tasks.
HOW IS TREMORS DIAGNOSED?
While Tremors are typically caused due to muscle fatigue, stress, aging, low blood sugar levels and stroke, a Neurologist diagnoses Tremors by performing a physical examination and neurological exam.
HOW IS TREMORS TREATED?
There is no cure for most tremors. Treatment to relieve them depends on their cause. In many cases, medicines and sometimes surgical procedures can reduce or stop tremors and improve muscle control. Tremors are not life threatening. However, they can be embarrassing and make it hard to perform daily tasks. Surgical intervention such as thalamotomy and deep brain stimulation may ease certain tremors. These surgeries are usually performed only when the tremor is severe and does not respond to drugs. Response can be excellent.
DID YOU KNOW?
The normal or physiological tremor is a fine, almost imperceptible, tremor that is difficult to see by the naked eye and does not interfere with activities. It can be seen in the fingers when the arms are outstretched. The frequency of the contractions is in the area of 8 to 13 cycles per minute. The cause of this tremor is not known, but it is not considered to be associated with any disease process.
