Demographic and Seizure Variables, But Not Hypnotizability or Dissociation, Differentiated Psychogenic from Organic Seizures

Abstract
Early detection and differential diagnosis of psychogenic
non-epileptic seizures (PNES) and epileptic seizures (ES) is a major
clinical issue in comprehensive epilepsy centers. Using blind conditions
with patients with PNES (N = 10) and ES (N = 31) before diagnosis,
we tested the hypotheses that individuals with PNES would exhibit
significantly greater dissociativity, hypnotizability, absorption, and history
of early abuse than ES patients. Although PNES patients tended to
show greater dissociative phenomena, only the last of our hypotheses
was fully supported. Although absorption did not discriminate between
the two diagnostic groups, it was significantly higher among those
reporting early abuse. A... (More)
Early detection and differential diagnosis of psychogenic

we tested the hypotheses that individuals with PNES would exhibit

show greater dissociative phenomena, only the last of our hypotheses
was fully supported. Although absorption did not discriminate between
the two diagnostic groups, it was significantly higher among those
reporting early abuse. A logistic regression analysis using scores on
dissociation, hypnotizability and absorption showed them to be poor
predictors of diagnosis; however, other analyses revealed that female
gender, reports of multiple trauma incidents lasting months or years,
initial seizure onset in late teens or twenties, and daily seizure attacks
significantly differentiated PNES from ES patients. Thus, demographic
and seizure variables proved to be much better predictors of diagnosis than psychological dimensions often associated with PNES. (Less)
