Will cognition return after discontinuing the topamax?

I was on Topamax for several years before being taken off of it. I was losing track of conversations in the middle of it, sometimes in the middle of a sentence. I could be talking to someone and then look at them and ask what we were talking about. It got bad enough to scare me into going to my PCP. They took me off the topiramate completely. It's been over 5 years since I last took a dose, and I still struggle with my memory and cognition sometimes. All the research says that most people lose the side effects once they no longer use this medication, but I seem to be that small percentage that stays affected. I struggle for words regularly, usually for a very simple word, which continually frustrates me as I have a more extensive vocabulary than many of my peers and coworkers.
I hope your brain fog lifted for you, but I regret ever taking this medication. The lasting side effects are not worth it and are beginning to compromise my effectiveness in my employment. Many times, my supervisors seem to act as if they think I am making up the memory issues or using it as an excuse.

I had migraines for about 30 years. Tried everything available until a neurologist started me on Topamax. I have been taking Topamax for about 15 - 20 years. Never experienced any brain fog. It did eliminate my migraines completely and never returned again. Have not stopped it because I don't want to risk the migraines coming back. So I guess I cannot answer your question completely. Am now 69 years old. Love my Topamax. Always make sure I get it even when in the hospital. Even had my brain function tested and came out on the top of the scale. So Topamax has had no bad affects on my brain.

Yeah it has that rep to cause fog. My cousins wife is an ER nurse... not someone you want working in a fog. She tried it and had to get off because of it. But the fog does lift if purely caused by the meds. She’s super sharp and funny now that she’s off of Dopamax. I was in it but not for very long. And the fog went away. I started Botox in June and that seems to help
