Tremor
Definition Tremors are a type of involuntary shaking movement.
Overview, Causes, & Risk Factors
Tremors are caused by problems with the nerves supplying certain muscles. They can affect the whole body or just certain areas (such as hand tremor).
Disorders where tremor is the primary symptom include:
-
Familial tremor (runs in families)
-
Essential tremor (no known cause)
- Drug-induced tremor (drugs known to induce tremor include valproic acid, lithium, and cyclosporine)
Parkinson's disease and other illnesses may cause tremors in addition to other symptoms.
