an elderly friend of mine had an episode of high blood pressure and was hospitalized. They started her on toprol. Since that time, which was about a year ago, she has exhibited signs of dementia - and they have increased over time. One minute she is coherent, the next minute she is not coherent at all. She can no longer focus well enough to do the simplest things. I had read that Toprol could have these side effects and, though her family did not believe me when I told them, they finally got the doctor to take her off the toprol for 3 weeks - but they said it did not make a difference so they put her back on the Toprol. QUESTION: HOw long would it take for someone to regain their full mental capacity after being taken off of Toprol- if Toprol were the problem? Would 3 weeks be long enough? AND what would be a better blood pressure medicine without this side effect that could be used with an 80 year old that has osteoporosis and emphysema?
