<s>[INST] I am 24, female. When I was 12, I had a grand mal seizure. After 1 year, I got an another one. After that, I was on dilantin for 4 years. My EEG, CT scan were all normal. I discontinued it in april,2005. Now, I am without medication since then and have not got any other seizure till now. (My brother also had a seizure once) Is there any chances for recurrence? Am I cured? [/INST] Hi, If you are reporting another seizure has occurred to you then, you are not cured and should contact your original doctor to inform them of what happened.  You may wish to see a neurologist (or epidemiologist) who may have other suggestions to the Dilation which has been largely replaced by other medications which are as effective in controlling seizures but without many of the side effects that can be produced (especially in women).  However, you still require medication of some type and another neurological workup (your brother as well) and you should do all of this as quickly as possible. Hope I have answered your query. Let me know if I can assist you further.  </s>
