I was never on antipsychotics, but the antidepressants and mood stablizers I was on for bipolar 2 took me from someone with a very sharp mind and great memory to someone who can't express myself well out loud. I can express myself when writing far better than when speaking. From my research, this is very common. I heard one former drug salesperson say how antidepressants have the same effect on a person's memory as having a stroke!!! Her name is Gwen Olsen if anyone wants to check her out--she has lots of videos on youtube. I believe it based on the person I was prior to taking these meds and who I am today.
