My mother started declining at 90. Over these past 8 years her short term memory has declined. She has lost some cognitive abilities. But she’s incredibly compliant, less moody, kinder, says thank you more often. People say she has Dementia but she’s hasn’t had the bad personality change. I sometimes think it’s just old age memory loss and cognitive loss. Anyone experienced this? She has now got 24 hr caregiving at home. They make her meals, take her out for drives, help her bath. But she can walk around on her own, still use bathroom. Can go out to restaurants. She’s very sweet! Trust me I’m not complaining, it’s just that she was negative and so narcissistic before.
