So, they were “surprised” not to find a slowdown toward the end of observation period, for obvious reasons of the ongoing pandemic linked to dementia presentation and progression. They have some explanation for this about the long onset, but just demographically, isn’t it also likely that killing off many of the people most likely to get a dementia diagnosis made a difference? I feel like they missed that thread.

Dunno, the probable link with microplastics in the brain worries me

this is rather positive. my boyfriend is worried because dementia affected both his grandparents. i’m glad to read each successive generation had lower rates.
