Is there a difference between Parkinson’s disease and essential tremor?
Parkinson’s and essential tremor are two different disorders that share tremor as a major feature. The exact nature of the tremor, however, is very different and can usually be distinguished by a movement disorder specialist. A small number of patients have both essential tremor and Parkinson’s but usually it is one or the other. Knowing which one a patient has is important because treatments are different.
