MRI/CT are clean, i am worried he is not diagnosed correctly and tell me how to proceed from here thank you. [/INST] Hello!Welcome on Healthcaremagic!My name is Dr. Aida and I am glad to attend you! You should know that there are many cases of epilepsy, which are not controlled by anti-epileptic drugs. Drug resistant epilepsy is the definition to these cases. As his brain MRI is normal, there is no macroscopic cause in his brain which can be removed to control his seizures. Anyway, I would recommend discussing with his doctor on the possibility of making some changes to his therapy and also vagal nerve stimulation as a possible surgical treatment option. Ketogenic diet is another treatment option in drug resistant epilepsy. You should discuss with his doctor on the above possible treatment options. Hope you will find this information helpful!Best wishes! </s>
