Interesting research into the prevalence and persistence of sensory symptoms in those living with motor FND compared to those living with stroke.

Well done @jonstoneneuro.bsky.social, Prof. Mark Edwards, Dr. Jan Coebergh, @roryhigginsphysio.bsky.social, @gnielsenphysio.bsky.social.

Many healthcare settings are ill-equipped to meet the complex needs of people with FND. Their repeated clinical presentations may reflect unmet needs rather than 'doctor shopping' or feigning. It is essential to improve public awareness of FND and education across all healthcare disciplines.

Encouragingly, recorded malingering diagnoses declined over recent years. This could reflect improved awareness and greater understanding of FND.

Some findings suggested clinician bias that could contribute to overdiagnosis of feigning in FND: malingering was more commonly recorded in Black individuals, individuals with socio-economic difficulties, and also in those with other stigmatised disorders, including STDs, viral hepatitis and HIV.

Compared with FND cases without recorded feigning, those with feigning codes showed greater clinical complexity, including more psychiatric, neurological and medical comorbidities, greater socio-economic adversity, and poorer recorded outcomes, including higher mortality.

Records of malingering and (less common) facititious disorder were rare in FND, appearing in about 2.2% of cases.

However, this was more common than in multiple sclerosis or depression.

The study analyses diagnostic coding patterns in over 200,000 cases.

We examined the prevalence of malingering and factitious disorder diagnoses in FND, their associated demographic and clinical characteristics, and potential evidence of clinician bias.

Clinical and demographic associations of recorded feigning in functional neurological disorder Analysing electronic health records, Berlot et al. found 2.2% of functional neurological disorder cases also had recorded malingering or factitious disorde

Using a large international EHR database, we examined how often, and to whom, feigning codes are applied in FND.

This is great - a really nice overview of recent FND network studies, and a friendly introduction to predictive processing theory in FND 🙌

New-onset FND appears more likely after COVID-19 than other respiratory tract infections. Both the severity of the triggering illness and pre-existing individual vulnerability may contribute to the development of FND.

I was asked by @braincomms to highlight their FND special collection which welcomes clinical and neuroscience research on every aspect of the condition.

Incredibly grateful for the opportunity to work on this with @liviaasan.bsky.social, @timnicholson.bsky.social, @bibastanton.bsky.social, Tom Pollak and Mark Edwards.

Our results suggest that both the severity of the precipitating illness and pre-existing vulnerability contribute to the risk of FND. They may have implications beyond post-COVID context, offering insights into how acute medical stressors interact with underlying vulnerability to precipitate FND.

The incidence of FND was higher after COVID-19 than after other respiratory tract infections. Following COVID-19, new-onset FND was more frequent in individuals with more severe acute illness and in those with greater pre-existing neurological, psychiatric and medical comorbidity.

Did the late Mark Hallett crack the code underpinning the physiology of free will? Free will is the brain’s constructed awareness that we are choosing our actions even though the brain initiates them before we consciously know it. Mark Hallett was instrumental in describing how it all works.

Crucially, adverse life events are not universally present in FND and should not form the basis for diagnosis. However, when they are present, the nature of stressors shapes the clinical phenotype and should inform an individualised management approach.

Using TriNetX, an international electronic health records network, we observed that stressors were more common in FND than in matched migraine or generalised anxiety disorder cohorts, with psychosocial stressors particularly common. Stressor type and timing were associated with clinical features.

Adverse life events and psychosocial stressors in functional neurological disorder: a retrospective cohort and case–control study using a large international electronic health record database A record of adversities was at least 2·5 times more common in FND than in migraine, and about 1·5 times more common than in GAD, varying by stressor type.
