Im 39 years old I have been on topamax for 3 months now on 50 mg a day first and now for the past month it was increaded to 75 mg a day. I have begun to have panic attacks/ nightmares. I also suffers from memory loss and inability form my words ( I guess thats the best way to describe it) my neuro gave me topomax for what he calls complicated migraines where my left sarm and leg became numg along with headaches and neck pain. The pain has decreased although the occurrrences have not subsided and Im not sure if Im going to saty on the Topomax. I have lost 8 pounds. The panic attacks and anxiety and debilitating.
