My mom is fairly young, she's 70 and I think she may be in the beginning stages of dementia. There is a history of it in her family. Two years ago she fell down her back stairs and hit her head. She was taken to the hospital and tests were conducted and it was determined that she was fine. Within the past year and half, she has become increasingly paranoid, forgetful and argumentative. She often doesn't make sense when she speaks. She is still seeing the neurologist that she was connected with after her fall. She has made mention of the doctor running more tests and when I ask why, she tells me that he is trying to rack up her bill, clearly that's not the reason. I've tried contacting her doctor and I know he can't tell me anything, but I at least want to express my concern for her health and well being to him. She lives alone and I worry about her and don't know what to do or where to start. I'veI've tried talking to her and she's not willing to cooperate with me, she wants to argue with me. Any advice or suggestions would be greatly appreciated.
