12 years ago at age 38 i started having night time seizures out of the blue they were full blown grand mal but only at night. My doctor put me on topamax 100mg before bed i have been seizure free up until a week ago i started having these deja vu like feelings and confusion and i would forget what i had done for 10 to 20 minutes. People who have been with me during these periods say at the start for approx 1 to 2 minutes i just have this blank uncomprehending stare but after that i am able to function with confusion for the remaining time. Afterwards i remember nothing of what happened during that 10 to 20 minute period. I went to the ER on the third incidence. I've had 5 now and the only thing abnormal was low potassium and my blood pressure which is normally 110/64 was 183/107 they attributed that to the seizure i have yet to get into see my neurologist cant get in until next week just wondering if anyone else has experienced similar symptoms.
