History of abuse and psychogenic nonepileptic seizures: A systematic review.
Psychogenic nonepileptic seizures resemble epileptic seizures but lack the physiological basis of epileptic seizures. We conducted a systematic review to explore whether childhood abuse is a risk factor for subsequent development of PNES. We reviewed only papers with an epilepsy control group, which employed strict criteria for diagnosis of epilepsy and well-validated tools for assessing abuse history. Odds ratios (ORs) for the different categories of childhood abuse and for childhood abuse as a whole were calculated where not previously available, and pooled ORs were calculated where suitable. In papers where OR could not be calculated data are presented as p values. Most Odds Ratios fell between 1.8 and 5.2 with relatively narrow confidence intervals. In 14 out of 18 calculations, 95% confidence intervals did not cross 1. This suggests that the chance of reporting abuse is higher in people with PNES than those with epilepsy and may be a causative factor in developing PNES. Several limitations of the data and directions for future study are discussed.
