Diagnosis and management of the patient with tremor.

Tremor is a common and disabling symptom that is associated with a large number of neurological disorders, including ET and PD. The positional properties of the tremor allow the clinician to generate a short list of diagnostic possibilities, which can then be narrowed down based on the clinical history and the neurological examination. A number of medical and surgical therapies are available for tremor, but a successful response to treatment depends on an accurate diagnosis.
