My pdoc suggests that my word retrieval problems are due to Topamax and not the Latuda/Thorazine combo I started on Aug 22. I thought he might be right as on Aug 10 I doubled the dose of Topamax from 45 to 90 mg a day. So to test his hypothesis, I went off Topamax entirely.

Knock on wood, no more word retrieval difficulties, at least none in the last couple of days. Given that Topamax is notorious for it and has even been dubbed Dopamax, I believe that was the culprit.

I took Topamax for appetite reduction, initially from April through early Aug at very little doses of under 15 mg and working up to 45 mg and did not have word retrieval difficulties at that time. So I will wait for a few more weeks to confirm it is indeed Topamax and then try reintroducing it at lower doses.

Has anyone had a dose-dependent word retrieval problem side effect on Topamax where you were able to tolerate small doses but not above?
