My Mother Is 83 With A Diagnosis Of Alzheimers And

My mother is 83 with a diagnosis of Alzheimers and heart disease. She has problems with her balance and often complains of "wooziness." She has a lot of different doctors and is on a lot of different medications - all of which could cause these symptoms. She is on 100 mgs of Zoloft and I am wondering if this could be causing the dizziness. She's fallen and continues to be at risk to fall. She began the Zoloft after my father died 4 years ago. I do not believe she needs it any longer and I am going to ask her doctor about it when we see her tomorrow. What do you think?
