My son, 17, was diagnosed with epilepsy in Nov. 2012. He has had eight seizures since this time. His trigger seems to be sleep deprivation, but the past three seizures have seemed trigger free. We are suspecting hormonal changes. My question is this: His seizures are always 3.5 to 4 months a part. After every seizure, there has been a medicine increase. He takes 3000 mg Keppra XR. Regardless of the medicine increase, the seizure happens in the same time period. Is increasing the medicine really doing anything? He is great on the Keppra, but it just slows his brain down, which is not beneficial for college.
