I believe that my 93-year-old mother took 2-5 mg Vesicare Tuesday. She has dementia, has had a stroke that resulted in seizures and is taking medication for both. The day after taking a whole Vesicare in the AM, I think that she seemed more spacey, forgetful. In addition to fearing bad effects from the 10 mg of Vesicare I m concerned that the whole Vesicare may be causing increasing signs of dementia! No thank you. I m not paying for information. I ll talk to he primary later today!
