TDC, typically developing children; FE, focal epilepsy; FE−Psych, FE without a psychiatric diagnosis; FE+Psych, FE with a psychiatric diagnosis; NA, not applicable.

TDC had significantly higher IQ than the FE group, t(86)=6.5, P=0.000. There were no significant differences in the IQ of the FE−Psych and FE+Psych groups.
