You might try to talk with her doctor. He will obviously be hesitant to discuss her medicla fiel with you. But, if you indicate that you are looking into seeking aconservtor for her, he mihgt give you some guidance, as to his opionion on the matter. Then you can go to the County Couselor's or Public Administrator's office in the county where your mother lives. They can give you some more guidance as to how you might start the process. They may even take over and brin ghte action themself, in some cases
Good luck
