Opioids occasionally cause myoclonus, seizures, and hallucinations.
myoclonus epilepsy
Prolonged oxygen deprivation to the brain, hypoxia, may result in posthypoxic myoclonus.
Levetiracetam is also effective for both generalised seizures and myoclonus.
The generalized seizures are usually well controlled by anticonvulsants, but the myoclonus soon proves refractory to treatment.
Photic stimulation may also be used to elicit myoclonus, especially cortical reflex myoclonus when present in photo-sensitive forms.
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.
Scientists believe that some types of stimulus-sensitive myoclonus may involve overexcitability of the parts of the brain that control movement.
Action myoclonus is the most disabling form of myoclonus and can affect the arms, legs, face, and even the voice.
Anatomically, myoclonus may originate from lesions of the cortex, subcortex or spinal cord.
