She speaks to people that are not there. She takes public transit at 6:30 to go to the Dr for a 7pm appointment. I don’t think she is taking her meds in a timely manner. She is constantly moving things and can not remember where they are. thinking they were stolen. Any thoughts or suggestion?
Hopefully you have all your legal ducks in a row and have a plan in case you go down the same path as she.
Do you or can you go with her to the doctor's office on her next appointment.
Make sure you are listed on any form giving permission for the medical team to talk to you. This is a HIPAA regulation, no one can discuss her condition if she has not given permission. Right now you can discuss concerns with the doctors office, send a letter to them or drop off a note. But until she has given consent do not expect a reply.
Depending on the advancement of the dementia it is possible that a lawyer will not allow her to sign any legal papers. They can talk to her and if they do not think she is cognizant you will not be able to become her POA. You or another family member can become her Guardian. If no one wants that role then the Court will appoint one.
But bottom line, right now there is nothing you can do.
If she already has a diagnosis of dementia from the doctor you could contact APS and report her as a vulnerable senior that can not care for herself. Call your States Elder Abuse hotline that will also get things moving. (self abuse, self neglect is reportable)
