A movement disorder can cause parts of the body to shake. This condition is known as essential tremor. It affects areas such as the hands, head, voice, or legs. A physical exam and medical history are key to distinguishing it from other conditions.

Further details about essential tremor are available, including what sets it apart from other tremors. A board-certified physician provides insight into the differences.

The distinction between essential tremor and other conditions is important, especially for older adults who may worry about related diseases.
