Functional Neurological Disorders in Children – a Historical Perspective

The modern diagnosis of functional neurological disorders (FND) describes a diverse set of neurological symptoms without identifiable pathology. The history of FND and its prescientific predecessor, hysteria, is complex and deeply rooted in sexism. Key moments in this history have contributed to the advancement of understanding in functional disorders that neurologists should be aware of. Although pediatric FND has a much less extensive historical literature, there are many parallels between it and the initial interest in hysteria by Charcot and other early modern neurologists. This was followed by waning neurological attention as psychiatrists promoted conversion disorder in the early 1900s. Towards the end of the 20th century, neurologists have taken a renewed, collaborative role with psychiatry and other disciplines to diagnose and study FND.
