My 65 Year Old Wife Of 48 Years, Has Had

My 65 year old wife of 48 years, has had many health issues. Heart, COPD, cancer, severe skin condition, and severe psoriasis. Earlier she started getting confused about her meds. Now, typically after supper, she looks for our children. She will call them by name. Walk around the house to find them. We have three children, the youngest left home 20 years ago. I told her that we need to go see the Dr. She she does not want to go. Stating that I will say things that make her look bad. She is up and stirring most of the evening. She seems fine in the afternoon. What comes next?
