Treatment - Epilepsy progressive myoclonic type 3 The medical treatment of progressive myoclonic epilepsy is often successful only for a few months or years. These patients may require more than one seizure medicine.[checkorphan.org]
Treatment Replacement therapy with high doses of exogenous enzyme, may halt or even reverse neurological progression although the outcome is not always favorable. 45.[slideshare.net]
Treatments For many patients, correct treatment can lower or prevent seizures. The most common treatment is anti-seizure medications. However, other treatment options are available.[cedars-sinai.edu]
