NEJM: Don’t mention the chess
Verghese. Joe Verghese. It only takes the briefest of internet searches combining 'chess' and 'dementia' to find the name.
Dr Verghese was the lead author of a journal article which is routinely cited amongst chessers on the internet. Leontxo Garcia recently called it "the best study" on the thesis that chess could, "prevent or delay Alzheimer’s". I don’t claim to be a "great expert", as Kasparov dubbed Garcia in that nonsense "many studies" tweet of his (Doctor Garry is In), but I have been looking into the subject for a couple of years off and on, and I’ve yet to discover anything better the research undertaken by Verghese and his colleagues either.

If you do, you’ll notice that there’s a problem. Actually, for an academic study which is supposed to be the proof that playing chess has a beneficial impact on your chances of avoiding dementia, it’s a very bizarre problem indeed.
Verghese’s article doesn’t actually mention chess. At all.
