How do I get my mother to go to the doctor?

Some of the ideas that I have read on this site include: telling her that you need a check up and ask her to go with you, only, it's to her doctor, explain that she needs her flu shot or some other kind of blood tests. I told my cousin that the doctor could order some medication that might help her memory and physical therapy that might help her balance. (She had terrible balance and was falling.)
Regardless of how you get her there, I'd prepare a list of your observations about her behavior and symptoms, so he can have a good idea of what you are dealing with and know how to approach her.

I've been told that dr's CAN AND WILL visit a patient in his/her home in order to SEE THE PATIENT. I haven't resorted to trying that, yet. Going to caregiver support seminars has helped ME exchange ideas with other caregivers (non professional capacity). There can be respite care so YOU can go out and DO LIFE for a few hours. Introduce the person (after a background check, etc) to Mom or Dad as a FRIEND here to help ME (not Mom or Dad) clean the house. Then you ask YOUR friend, "can you stay longer? Finish this while I'm out running errands?"
This is my plan. Very soon. Good Luck!
PS: declining mind can cause them to say very cruel things they normally never would have. It's not them TRYING to be difficult. It is their inner frustration. Body language is key in communicating that you are HAPPY helps. They can read body language at any level of the disease. Even if they forget who you are!

I had the dr office call Mom and say, "your Annual checkup is such and such at such and such time, we'll see you then!" They left it on her voicemail and she went!

When she was just barely sick (UTI and a cough), I told her that if she WON'T go, I'll get sick, too, and then we'll have nobody to care for US. That worked THIS TIME.  It's also true.  When Mom got pneumonia, I got the lung infection from being in the same home.  

One ploy advised on the forum was to tell them their insurance requires an annual check up or they will be dropped, I thought that was pretty clever!
