My mum has recently become confused and getting muddled up. I was wondering if there are is any medication an oncologist would prescribe to help with this? She is only 66 and I am really at a loss of what to do as she seems to be going down hill quite quickly despite being told 2 weeks ago that a different chemotherapy treatment would be beneficial to her.

Thank you, I'm not really sure why I'm writing this but I am at a loss as to what to do.
