Topic Collection

Functional Neurological Disorder (FND) is a common disorder, produced by functional disturbance in the brain, as opposed to a structural abnormality; patients can present with almost any neurological symptom. There has been a renaissance of interest in Functional Neurological Disorder in the past two decades, with the importance of FND being increasingly recognised. This Topic Collection in BMJ Neurology Open aims to synthesise current theories and models of FND, explore emerging trends and highlight cutting edge FND research.
