Background: Epilepsy is a prevalent disease worldwide. Executive functions and social cognition are essential in daily living functioning, academic performance, and social adjustment. This study attempts to investigate the executive functions and ability to abstract social concepts in adolescents who have idiopathic generalized epilepsy and assess if the deterioration in executive functions can predict deterioration in the ability to abstract social concepts. Sixty adolescents with idiopathic generalized epilepsy aged between 12 and 19 collected from the neurology outpatient clinic at Sohag University Hospital in Upper Egypt were compared with 60 age- and sex-matched healthy adolescents regarding performance on executive function tests and ability to abstract social concepts tests. We used the Tower test to assess planning, the design fluency test to assess cognitive flexibility, the verbal fluency test to assess verbal fluency, and the Stroop test (overlapping between colour and word test) to assess inhibition and ability to abstract the social concepts test, which is composed of verbal part and performance part. Results: Adolescents who have idiopathic generalized epilepsy have worse executive function impairment in all executive functions than control adolescents. Adolescents with idiopathic epilepsy have significantly more impairment in the ability to abstract social concepts (verbal and performance) compared to control adolescents. There is a significant correlation between executive functions and the ability to abstract social concepts (verbal and performance) in epileptic and control adolescents. Impairment in some executive functions can predict impairment in the ability to abstract social concepts (verbal and performance) in epileptic and control adolescents. Executive function impairment is correlated with the duration of illness, frequency of seizures per year, time since last epileptic fit, and presence of interictal epileptic discharge in EEG in the patient group. Conclusions: Executive functions and the ability to abstract social concepts are significantly impaired in adolescents who have idiopathic generalized epilepsy. Impairment in executive functions can predict impairment in the ability to abstract social concepts. There is a need to screen executive functions and social abilities of adolescents with epilepsy and programmes to enhance these abilities. [ABSTRACT FROM AUTHOR]
