I was on Zoloft years ago after a miscarriage that landed me in the hospital with sepsis on a ventilator. I was suffering from terrible memory loss -- some of which was initially from being on the ventilator. But that initial severe memory loss resolved, and I was still experiencing memory loss that was interfering with my daily life. I asked my pulmonologist (who is also a psychopharmacologist) about it and he asked what drugs I was taking. I told him Zoloft and Zyrtec (an OTC allergy med). He told me that both drugs are known for causing memory loss and suggested I discontinue both. I went off of both and memory issues resolved! Hope this helps...
