My mother is at this same rehabilitation hospital and we are experiencing the same problem with the dementia. My mother's mental capacity has greatly diminished during her 3 week stay at the hospital. We were told that none of the medications she's being given would cause her to behave the way she is (speaking non stop, all day, vivid wild hallucinations, responding to circumstances she has created in her own head as if they were real, etc.). This behavior has developed quickly in a matter of weeks. The previous review mentions MS Cotin. I will research ths more online. Fortunately, we will be moving her to a new facility soon. Thank you for your review kcristnr. It helped me alot.
