Essential tremor doesn't cause other health problems. However, people with essential tremor sometimes develop other neurological symptoms, such as an unsteady walk.
In years past, the term “benign,” meaning “harmless,” was a standard part of its name, as in “benign essential tremor.” However, experts now recognize that while essential tremor isn’t harmful directly, it can cause severe disruptions in your life.
Essential tremor (ET), also called benign tremor, familial tremor, and idiopathic tremor, is a medical condition characterized by involuntary rhythmic contractions and relaxations (oscillations or twitching movements) of certain muscle groups in one or more body parts of unknown cause. [6]
Essential tremor disorder is a neurological condition that causes your hands to shake rhythmically. The head, trunk and voice might also be involved, but hand shaking is most prominent. The cause is not known, but it is often passed down from a parent to a child.
Essential tremor (benign essential tremor or familial essential tremor) is a neurological condition. Your hands shake involuntarily, usually with simple movements such as writing or tying shoelaces. Over time, the tremor can become more pronounced, making it difficult to complete everyday activities.
