If catched early enough, that could save some memories before they're destroyed

And as the long term effects, at least in mice, look promising, I'm kinda hopeful

Was absolutely awful watching my grandmother decline - and because of that, my mother is horrifically afraid of getting dementia

I hope this can translate from mice to humans fast and we can get something similar.

Restoring destroyed neurons will probably never be possible...
But at least we can stop the decline and new memories can be stored again, and with that a kinda normal life
