We then consider causation within common legal frameworks using a predisposing-precipitating-perpetuating model to analyze the contribution of index events, background vulnerabilities, and the litigation process itself.

Unlike other neurological disorders, FND is not caused by structural brain damage but by disruptions across brain networks involved in agency, attention, emotion processing, sensory-motor control, and interoception. These alterations align with alterations in predictive coding, which propose that abnormal prior beliefs override sensory input, contributing to symptom generation. Early-life trauma is a significant risk factor, interacting with genetic and epigenetic vulnerabilities that influence emotional regulation, stress sensitivity, and brain connectivity. Psychiatric comorbidities are also common and may affect symptom severity and prognosis.
