AB A  large  proportion  of  patients  undergoing  video-electroencephalography  monitoring  (VEM)  do  not  have  epileptiform  electroencephalographic  (EEG)  changes  during  their  spells,  and  approximately  one  third  of  patients  admitted  to  tertiary  care  epilepsy  monitoring  units  are  ultimately  deemed  to  have  nonepileptic  spells.1,2  In  a  relatively  small  proportion  of  these  patients,  physiological  causes  for  their  events  (e.g.,  cardiac  arrhythmia  and  hypoglycemia)  are  found,  and  a  majority  of  these  patients  are  discharged  with  a  definitive  diagnosis  of  psychogenic  nonepileptic  seizures  (PNES).  Many  other  terms,  as  listed  in  Table  20-1,  are  used  to  describe  the  exact  same  phenomenon.3  The  diversity  of  the  terms  used  to  describe  this  disorder  makes  it  difficult  to  gain  a  comprehensive  survey  of  the  available  literature.  Additionally,  there  is  considerable  overlap  of  features  present  in  PNES  and  those  of  other  functional  neurologic  disorders,  such  as  psychogenic  movement  disorder  and  psychogenic  pain  disorder.  From  the  observation  of  this  overlap,  a  spectrum  of  disorders  is  likely  represented  under  the  umbrella  of  conversion  and  somatization  disorders.
