I do not know whether that would be appropriate or allowed under the Hippa laws; however, if you have a concern about your mother's mental abilities, I think it can be appropriate to communicate that to the doctor by calling to talk with the doctor or nurse or making an appointment. The doctors are often able to do some simple testing as part of a regular exam and then can recommend further testing if they see an issue. You can also request to go with your mom to an appointment. What I would suggest is that you tell your mother that you know it is hard to remember everything the doctor is saying and so you are volunteering to go to write down what the doctor says (you can also volunteer to keep track of the questions she wants to ask) so that she can have that to refer to later. That can be a helpful way to become a part of the examination process and to get a sense of whether the doctor is aware of the memory problems you observe.
