Welcome to this group that I found on one of my teary days. My husband was diagnosed with MCI in March 2023 but showed memory issues much earlier. I have posted some long replies. Yes there are subtle personality changes-more anxiety, irritability and conversations are different. We are married 50 years and yes, the relationship changes but we are still enjoying each other as long as I practice patience and keep my sense of humor and empathy. I’ll reply more and see what others say. This is so helpful.
