This discussion of the evolution of psychiatric knowledge concerning psychogenic non-epileptic seizures (PNES) sheds light on the epistemological assumptions underlying the concept and on its practical implications as well. PNES are defined as repeated seizures or attacks which can be mistaken for epilepsy because of the similar behavioral changes displayed, but which differ in that they are no...

Huntington's disease (HD) is a neurodegenerative condition characterised by motor dysfunction with involuntary movements and loss of voluntary control, cognitive deterioration and psychiatric problems. We report a 51-year-old man with early HD who experienced stereotyped episodes of repetitive, purposeless complex movements and unresponsiveness. His neurological examination was compatible with ...

We welcome the comprehensive and timely systematic review of suggestive seizure induction for psychogenic non-epileptic seizures (PNES) by Popkirov and colleagues [1]. As the authors of two of the studies cited in this review we would like comment on two issues. The first concerns the degree of honesty or deceptiveness of the communication strategies employed. We agree that avoiding deception i...

INTRODUCTION Psychogenic non-epileptic seizures (PNES or "pseudoseizures") remain an obscure topic in the peri-operative setting. They are sudden and time-limited motor and cognitive disturbances, which mimic epileptic seizures, but are psychogenically mediated. Pseudoseizures occur more frequently than epilepsy in the peri-operative setting. Early diagnosis and management may prevent iatrogeni...
