Résumé

Functional, often called psychogenic, disorders are common in neurological practice. We illustrate clinical issues and highlight some recent research findings using six case studies of functional neurological disorders. We discuss dizziness as a functional disorder, describing the relatively new consensus term Persistent Posturo-Perceptual Dizziness (PPPD), axial jerking/myoclonus as a functional movement disorder, functional speech symptoms, post-concussion disorder with functional cognitive symptoms and finally advances in treatment of dissociative seizures and functional motor disorders.
