Multidimensional psychopathological profile differences between patients with psychogenic nonepileptic seizures and epileptic seizure disorders

•Increased levels of psychopathology are experienced by individuals with psychogenic nonepileptic seizures.•Scores for childhood trauma, dissociation, and depression are particularly raised in these patients.•High correlation between psychopathology measures allows the construction of a single general psychopathology score (‘p’ factor) to explain major variance in underlying psychopathological scores.•Understanding of psychometric profiles of patients presenting with undifferentiated seizures at a construct level might help triage patients and guide further psychiatric examination and enquiry.
