title: Late onset psychogenic nonepileptic attacks.
abstract: OBJECTIVE
  To investigate differences between groups of patients with early vs late onset psychogenic nonepileptic attacks (PNEA).
  
  
  METHODS
  The authors compared patients with onset of PNEA after age 55 years (n = 26) to patients whose onset of PNEA was before age 55 years (n = 241). The authors examined sociodemographic variables, factors potentially predisposing to PNEA, clinical semiology, and medical and psychiatric background.
  
  
  RESULTS
  Patients with late onset PNEA were more likely to be male (p = 0.029) (p values are quoted uncorrected for multiple comparisons). They were less likely to report antecedent sexual abuse (p = 0.008), and more likely to have severe physical health problems (p < 0.001) and to report health-related traumatic experiences (p < 0.0001). There were no clear differences in PNEA clinical semiology. There was a trend to better baseline mental health in the late onset group.
  
  
  CONCLUSIONS
  The data suggest a distinct subgroup of patients with late onset psychogenic nonepileptic attacks, in whom psychological trauma related to poor physical health plays a prominent role.
