Yes it is the only way to find out. What is really strange is my therapist actually asked me what I thought my diagnose is. I said clinical depression, anxiety associated with panic attacks because my family doctor diagnosed me with anxiety with assocaited panic attacks in 2003. That was the start of paxil and zanax treatment. she never said anything until my last appiontment she said I had early onset dementia from the years of taking alprazolam. or it was more like they think that and need to plan a taper. the last taper I did was fluoxetine and he told me to just stop taking it, I refused and said it had to be slower 3 months later i was off it he called me at home and told me to start taking it agian because i seemed confused . so eyesclosed thanks u
