What Is Nonessential Tremor?
While there isn't a medical condition classified as a nonessential tremor, there are seven specific categories of tremors, according to the National Institute of Neurological Disorders and Stroke. These categories include benign essential tremor and Parkinsonian tremor as the most common types.
The most common form of tremor diagnosed is a benign essential tremor, as reported by the National Institute of Neurological Disorders and Stroke. For some patients, these tremors are mild and don't interfere with daily activities, but for others, the tremors can affect both sides of the body and are quite bothersome, especially if the hands are involved.
Parkinsonian tremors are resting tremors that eventually affect both sides of the body and usually occur after the age of 60, as described by the National Institute of Neurological Disorders. These tremors are often the first symptom of Parkinson's disease.
