The impact of hormonal changes on Functional Neurological Disorder: An International Online Survey

Introduction: Functional Neurological Disorder (FND) affects women approximately three times more often than men. This disparity has largely been attributed to higher trauma prevalence and diagnostic bias, while the potential contribution of hormonal influences has received little attention. Methods: An online question...

Altered Interoceptive Predictive Coding in Functional Neurological Disorders

ABSTRACT Interoception, the processing of internal bodily signals, has been linked to the pathophysiology of Functional Neurological Disorder (FND), along with the theoretical concept of altered predictive coding (PC). FND symptoms such as sensory‐motor dysfunction may arise from disrupted integration of sensory input...

Virtual environment benefits motor dysfunction in Functional Neurological Disorder: Evidence from Virtual and Augmented Reality

Background: Virtual and Augmented Reality (VR/AR) are increasingly used in medicine and may offer novel interventions for Functional Neurological Disorder (FND) by targeting mechanisms of impaired motor control. However, evidence for the effect of different modalities on movement in FND is limited. Moreover, it is hypo...

The oxytocinergic system in functional neurological disorder: Preliminary testing of associations with interoception and childhood trauma

The oxytocinergic system has been proposed as a vulnerability factor in the pathophysiology of Functional Neurological Disorder (FND), a condition associated with stressful life-events and disturbed bodily awareness. Recent work from our group demonstrated reduced interoceptive function alongside elevated salivary oxyt...

Mega-analysis of Structural Brain Imaging in Functional Neurological Disorder.

This large mega-analysis of brain structural morphometrics derived from T1-weighed MRI scans from fifteen international research groups suggests subtle morphometric differences, particularly in prefrontal and motor regions, may represent predisposing vulnerabilities, compensatory mechanisms, or FND-specific alterations...
