Leading FND Site Confirms Criticisms on Prevalence Outlined in Our Letter to Neurology Journal
In two recent posts, here and here, I wrote about our letter on inflated prevalence claims for functional neurological disorder (FND) and about the response from the authors of the study we criticized.

Unconvincing Response to Letter on FND Prevalence Inflation
As I wrote in a post the other day, the journal NeuroImage: Clinical has just published a letter from a group I organized about the misrepresentation of findings regarding the prevalence of functional neurological disorder (FND).

A Letter Requesting Corrections of Inflated Prevalence Rates in Nine More FND Papers

The article included the false claim that a seminal 2010 study found that FND was the second-most-common diagnosis at outpatient neurology clinics.

Once More Regarding Inflated FND Rates–and a Reprise of a Letter to a Yale Neurologist
Last July, I sent a letter to Benjamin Tolchin, a neurologist at Yale, about the statement, in a 2021 paper for which he was the lead author, regarding prevalence rates for functional neurological disorder (FND). Last month, I sent it again. I’ve still had no response. I am reposting it below because related claims about…
