This is a very difficult and sensitive situation. As long as they are mentally stable, there is little that you can do to force them to change. A couple of options include applying for conservatorship. You will need an attorney and about $5,000 though to do this and the court can appoint you as a gaurdian or POA. You can contact your local crisis team (call the police department for the number) and report that she is unable to care for herself because of physical/mental problems which is known as self-neglect.
It sounds like to see what you can do and what services your state offers, you would contact the Indiana State Department of Health at 1-800-433-0746.
Good luck!
