Thanks for such a detailed and elaborate question. You have mentioned almost all of the details very nicely. Your physician was right in saying that the MRI
donot show a seizure
discharges and its only the EEG which shows seizure discharges. If EEG is showing it, there is no doubt why you shouldn't be on anti epileptic. Valproate
are two good anti epileptics and you should try them if not recovering. If symptoms do not improve with them, only then some antipsychotics may help you. Now that you are in India, we would advice you to take a neurologist
consultation in India with all your old records. What you have not mentioned in your account is what medications are you currently on. In case if you are not on any medication, do start the anti-epileptic as soon as possible.
Hope I am able to solve your concerns.
