David Putrino, a neuroscientist and physical therapist, is director of rehabilitation innovation at the Mt Sinai Health System in New York. Over the last three years, the rehabilitation center he oversees has worked extensively with patients experiencing prolonged symptoms after an acute bout of Covid-19, or what has become known as long Covid (LC). On Monday, he posted a thread beginning with this:

"We are in our fourth year of work to understand #LongCovid and we now know things about it thanks to science. After being told again by a quasi-well meaning, if uninformed, clinician that LC is just functional neurological disorder (FND). Here’s a thread on why LC IS NOT FND.“

I spoke with Dr Putrino earlier today about his thread and some of the push-back it received.
