How do you assess myoclonus?

Doctors diagnose myoclonus based on symptoms and do blood tests, electromyography, and/or magnetic resonance imaging to identify the cause. The cause of myoclonus is corrected if possible, but if the cause cannot be corrected, certain antiseizure drugs or clonazepam (a mild sedative) may lessen symptoms.

What is Propriospinal myoclonus?

What causes Propriospinal myoclonus?

Propriospinal myoclonus is idiopathic and has occurred following spinal cord lesions, spinal trauma, drug use, tumor, or infections. However, a specific cause is identified in only 20% of patients.

How do I calm myoclonic jerks?

Anti-seizure drugs that treat epilepsy can relieve myoclonus. If a person experiences mild myoclonic seizures, which last for a few seconds, they may not need treatment.
