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. The 2021 article in NeuroImage: Clinical, “Neuroimaging in functional neurological disorder: state of the field and research agenda,” asserted that FND was the…

Finally, Our Letter on Inflated Claims of FND Prevalence Is Published
For more than a year, I have been criticizing experts in the field of functional neurological disorder for misrepresenting the findings of a seminal study, in effect tripling the reported prevalence rate of the condition. These untrue claims about the Scottish Neurological Symptoms Study (SNSS)—specifically, that the prevalence of FND among outpatient neurology clinics was…

Study Finds “Elevated Brain Injury Markers and Reduced Grey Matter Volume” a Year After Hospitalization for COVID-19
A British study of neurological sequelae in patients many months after hospitalization for COVID-19 has found that “post acute cognitive deficits…were associated with elevated brain injury markers in serum and reduced grey matter volume,” according to a pre-print posted earlier this week.

Update on Our Letter Concerning the Prevalence of Functional Neurological Disorder
In August, I submitted a letter to NeuroImage: Clinical concerning inflated rates of prevalence of functional neurological disorder, on behalf of myself and nine colleagues. After the letter went through peer review and a round of revisions, I was informed in early November that it had been accepted, as I noted in a blog post.…

Letter on Inflated FND Prevalence Rates Accepted for Publication
As I have regularly noted, patients with diagnoses of functional neurological disorder (FND) experience tremendous suffering. A patient who goes by the moniker @FnDPortal has written a compelling and sometimes harrowing essay, Cadenza for Fractured Consciousness: A Personal History of the World’s Most Misunderstood Illness, that is well worth a read in order to understand some…

A Follow-Up on a Post About Whether Anxiety and Depression Perpetuate Functional Limb Weakness
Zachary Grin, a physical therapist in New York City who specializes in treating patients with functional neurological disorder (FND), commented on my most recent blog after I posted a link to it on X, the social media platform formerly known as Twitter. As he noted in his series of tweets (or his series of Xs?),…

Depression/Anxiety Not Linked to Negative Outcomes in Patients with Functional Limb Weakness, FND Experts Report
The Journal of Psychosomatic Research has just published a paper called “The Impact of Depression, Anxiety and Personality Disorders on the Outcome of Patients with Functional Limb Weakness – Individual Patient Data Meta-Analysis.” As I have previously noted, the journal is something of a house organ for seriously flawed research from adherents of the what…

Letter to Journal about Inflated Claims of FND Prevalence
I have spent some time trying to correct the record on the reported prevalence of functional neurological disorder (FND). As I have documented, leaders of the FND field have spent the last decade misrepresenting the findings of a seminal 2010 study, Stone et al, to claim that this diagnosis is the second-most-common presentation at outpatient…

That Whine De Coeur about NICE’s Rejection of GET/CBT Regimen, and ME Action UK’s Disappearing Rebuttal
On July 10th, the Journal of Neurology, Neurosurgery, and Psychiatry (JNNP) published what can only be called a whine de coeur from a bunch of academics and investigators on the wrong side of a dispute with Britain’s National Institute for Health and Care Excellence (NICE). Their article was called “Anomalies in the review process and…

Update on Efforts to Correct False Statements about FND Prevalence
I have continued writing my letter-writing effort to alert journals about papers on functional neurological disorder (FND) that have included false statements regarding the prevalence of the condition reported by a seminal study in the field the reported prevalence of the condition. (I was going to refer to this as a “letter-writing campaign” until I…

A Letter to Psychological Medicine about Inflated FND Rate Claims
The journal NeuroImage: Clinical, an Elsevier title, recently agreed to correct the false statement that a 2010 study found functional neurological disorder to be the second-most-common diagnosis at outpatient neurology clinics. To the journal’s credit, it responded positively within days of receiving a letter about the matter from a group of us, although the correction…
