What Are The Causes And Complications Of Essential Tremor?

Essential tremor is a movement disorder where a patient experiences involuntary shaking with a rhythmic motion, most often in their hands. Essential tremor is different from a tremor that occurs as a complication of another disorder or trauma to the head. Other neurological symptoms occur alongside essential tremor as they do with a tremor that has other causes. Essential tremor is most prominent when affected individuals are making movements and performing different activities such as drinking, eating, and writing. Essential tremor is prominent when the affected part of the body is extended, and the muscles being used are opposing gravity. Aside from the hands and arms, essential tremor can occur in the trunk, head, face, and neck. Essential tremor can manifest at any age but tends to be most prevalent in older adults.
