Worried about my 6 yr old son

~~Hi , Im wondering if anyone has any history of their child having myoclonic epilepsy? My son was diagnosed at 2yrs old as having benign myoclonus and then discharged , eeg did show abnormal activity but the consultant was not concerned. He is now yrs old and three months ago he had a seizure that lasted 6 mins which was an awful experience. Having recently seen a consultant (yesterday) they now think he has myoclonic epilepsy. I can not find much info on this can anyone help me please
