I believe the least painful life is lived on the middle path so I broadly agree, but not all will.
Other HN commenters have said that it's well known by teachers in the West and IIRC I've read articles that it's also well-known among priests and monks in Eastern traditions--so much so that the ancient practices and teachings incorporate rules and stories designed to address it. The names or labels attached may differ between Western medicine and Eastern religion, but the phenomena are the same and generally considered negative and harmful, nor positive or curative.
It's rare but real. What's to be gained from denying it? It doesn't reflect poorly on meditation in the slightest, it's just an admission of our human frailty and that there are no panaceas.
