Parkinson's and Essential Tremor, 2

Is there a difference between Parkinson’s Disease and Essential Tremor? If so, can they explained in language that a lay person can understand?

Good question. There have been multiple studies and many descriptions of these two conditions. Essential tremor and Parkinson’s disease are both neurological conditions. It so happens that tremors are a characteristic feature of both. One description pointed out that Essential Tremor has an autosomal dominant trait (e.g., a pattern of inheritance in which an affected individual has one copy of a mutant gene and one normal gene on a pair of autosomal chromosomes). Parkinson’s disease appears not to have this pattern of inheritance and is related to dopamine. The characteristic clinical feature of Essential Tremor is bilateral, low amplitude tremor, prominently in the upper limbs. Parkinson’s disease is a movement disorder that can eventually include cognitive impairments as well—especially in the late stages.  The reference below is written in easy-to-understand language.
