I conducted a search for "long term effects of Topamax" and discovered this site, and am so glad to have done so. I have been on Topamax for around 2 years now, at the 200mg level, for chronic, sustained migraines. I have figured out, through tracking, that I will get a migraine lasting 3-4 days during ovulation and again on my period. The Topamax has helped considerably with the headaches, although I do still get at least one per month. It is generally not of the same duration, though, and is fairly easily controlled with pain meds. I've been a bit worried, though, about continuing the drug for life, as it seems I need to do to control these headaches--thus the search. I, too, have experienced the "mental fog," and general decreased cognitive abilities. I am an extremely intelligent person, a writer, a former English teacher. Why am I unable to pluck words from my brain when I need them? I've also experienced the tingling and numbness in various extremities, sensitivity to cold, blurred vision, fatigue, and loss of taste sensation. I've also become a royal bitch to my husband and children--although I had no idea that this could be related to this medication. I feel relieved to know this now...to know that I can change and be the person I once was. I don't like myself very much right now, but it's like trying to stop a runaway train. I can no sooner prevent or alter my knee-jerk reaction to things than I can stop that train. I've been off of the Topamax for approximately two weeks now, and have already gained 5 pounds, although I work out 2-3 hours daily and play competitive volleyball 2-3 times per week for several additional hours. I had initially lost around 18 pounds and kept it off, even when my appetite returned. I'm uncertain, though, why I'm gaining the weight back so rapidly. I'm eating fewer than 1500 calories/day and exercising like crazy. It doesn't make sense. I don't care about the weight, though. My chief concern is the return of my cognitive function. Has anyone experienced a return to their prior cognitive state after getting off of this medication?
