Gaucher's disease can be diagnosed through enzyme testing as it is a metabolic disease. [4] Lafora's disease can be diagnosed using skin biopsies. [4] While Action myoclonus renal failure (AMRF) syndrome can only be diagnosed using genetic test. [4] Using EEG's as a form of diagnosis can prove difficult as patients differ in their neurophysiology.
Patients typically present to medical providers following their first generalized tonic–clonic seizure, by which time they have often had myoclonus for several years.
