What is essential tremor?
Essential tremor affects millions of Americans, causing involuntary shaking (known as tremors) in any number of areas of the body—and even the voice. Despite being the most commonly diagnosed movement disorder, the cause behind essential tremor is unknown. Although it can start at any age, people over 40 are at greatest risk for developing essential tremor.
Although tremors can have a big impact on daily life—and typically get worse over time—they are not dangerous and are not usually a symptom of a more serious condition.
