Hello. Thank you so much for your response. We live in a very rural area and programs and services are limited and mostly require driving a distance. I am just starting and slowly learning how to advocate for my husband. Up to now he has resisted my involvement in his healthcare. I just started going to appointments with him. I also have started managing his medications for him (filling a weekly medication dispenser). This was necessary because he had started getting confused about when he had taken his meds and a couple times he took a double dose! I keep all his meds in a lock box now. As far as the PET scan/ psychiatrist: we got a letter from the Mood and Memory clinic saying they received our referral and unfortunately have a very long wait list. They are scheduling a year out. They said they would call us when an appointment was available. I asked to be put on a short-call or cancellation list which they were happy to do. Fingers crossed there. My husband does have a CPAP but he doesn't tolerate it. He recently had another sleep study because we thought he might be able to get an "Inspire" device which is like a pacemaker implant for breathing. But my husband's apnea is not just obstructive, but also central nervous system-related, so he is not a candidate for that. He may need supplemental oxygen at night. His O2 saturation becomes dangerously low about 30 times a night! Who knows how that is affecting brain function As far as his diabetes--- that has become a big challenge because he has become very impulsive about eating. It just feels like a lot to deal with. Everything takes time.
