Nonexpert raters can, with fair to moderate reliability, rate features characterizing ictal impairment of consciousness and responsivity in video recordings of seizures. PNES are associated with greater peri-ictal responsiveness to the social environment than epileptic seizures. These findings are consistent with a potential communicative function of PNES and could be of differential diagnostic significance.
