I wrote a paper on Vimpat last semester, and it seems to have a different mechanism of stopping seizure activity. There are several actions that take place in transmission of electrical activity that can have an affect on allowing a seizure to develop. Each drug may focus on one or more of those actions. However, in case it does not work and with the statistics being what they are re meds, once one aed fails to stop the seizures copletely there is less than a 15% chance that any AED will ever stop them, please seek out an Epileptologist at a Comprehensive Epilepsy Center and discuss other options. There are other options, and with TLE and being refractory, that may be where you find your new life. Complex patials are the hardest to stop with meds. Tattoo
