One insight from my worsened memory in recent years (whether a Covid after effect ot aging or something more ominous) is how clear  the link between emotions and memory is. Things that never evoked any emotion are most easily forgotten.

I used to think strong emotions reinforce the associated memories. Now I think all memories are intrinsically sentimental. If you could truly care about nothing you’d have true amnesia. Identity is memory is temporally coherent sentiment history.

People with very strong but not eidetic memories simply have a high baseline of caring mildly about almost everyone and everything in the world. My mom is one such person (in her 80s she still remembers like a hundred plus birthdays of extended family members; it’s her freak superpower). 

I used to have a strong general knowledge memory of history, science etc, but not for personal info.

If I were experiencing cognitive decline right now, I’d at least experiment with ultrasound therapy to the brain. Here’s the protocol of a current study trying to reproduce the findings of a buried UofAZ study (Hammeroff) that claimed to reverse alzheimers.

I don't know how big a self-experimenter you are, but this seems like a pretty safe protocol, and I think is a promising therapy for preserving memory (and I wish you maximal brain function): https://warpcast.com/danfinlay/0x095d1c73
