Hi Sorry for the late reply. Yes my Mom's dementia was noted during the exam. I brought with me all her medical exams and the doctor asked her the typical questions neurologists would ask to test the memory. For the interview, I had guardianship papers ready so I informed the agent about her situation and I did the interview on her behalf but they asked her where I live, Luckily she remembered. All in all the interview took less than 5 mins.
