Did you ask your T about your mother? I would think that would be the first step I would take if it were my Mom. Also, many Ts, including my own, list that they see seniors. GP's who specialize in geriatrics would also have suggestions. I would also make sure she doesn't have a new medical problem. I know that many people close to 90 and older lose their will to live, like my Dad did. But many don't! I hope you can get your Mom the help she needs.
