• Scientists believe that some types of stimulus-sensitive myoclonus may involve overexcitability of the parts of the brain that control movement.

• When patients are taking multiple medications, the discontinuation of drugs suspected of causing myoclonus and treatment of metabolic derangements may resolve some cases of myoclonus.

• Photic stimulation may also be used to elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms.

• The generalized seizures are usually well controlled by anticonvulsants, but the myoclonus soon proves refractory to treatment.

• Levetiracetam is also effective for both generalised seizures and myoclonus.
