But it may allow for neural regrowth, at the cost of some preformance and some memories but maybe reconnect things with time and "work". Work that would be useless since plaque forbid proper functionning anyway (IIUC).

> neural regrowth

I didn't know this was possible. Is it ?

It was only recently discovered that healthy brains regrow neurons all the time.

Not throughout the brain. It's only known to occur in two regions, the dentate gyrus and a part of the subventricular zone.

You're talking about neurogenesis via progenitor cells and neural stem cells. Evidence was there for several decades but anyone that touched the subject was essentially blacklisted from the neuroscience community. At MIT, they would talk about how Kaplan was denied tenure and basically kicked out of his university because of his lab's controversial focus on neurogenesis. Kaplan feels similarly. Here's his personal account entitled: death of a dogma and a research career.
