Myoclonus

Symptoms

Myoclonic jerks vary widely. They can occur in many locations — affecting the face, the hands, the legs, or the entire body.

The jerks may be regular or irregular, continuous or sporadic, and may occur at rest or during movement.

They may be mild or debilitating. A patient may also experience more than one kind of myoclonus and the myoclonus may stay the same over time or may change.

Myoclonus may also be only one of various other symptoms connected to a common underlying disorder.
