Background: Subtle cognitive deficits and defective school performance were previously reported in school children with Benign Focal Epilepsy (BFE). Objective: To assess possible alterations in cognitive and psychological functions in school children having BFE in comparison to age and sex matched healthy children. Methods: Neurophysiological assessment using EEG, P300 and Contingent Negative Variation and Neuropsychological assessment using Wechsler Intelligence Scale for Children were carried out on 30 school children  (age 5-11 years ) suffering from Benign Focal Epilepsy as well as 30 age and sex matched healthy children. Results: Patient group had significantly lower P300 amplitudes (p= 0.02), and tendency to higher mean CNV. Patients who had  right side EEG spikes had significantly lower scores in the Total IQ, and Total Verbal IQ however patients who had left side spikes had significantly lower P300 amplitude (p= 0.04) and higher mean Contingent Negative Variation . Conclusion: Benign Focal Epilepsy is a probable cause of cognitive deficits and educational problems among school children. [Egypt J Neurol Psychiat Neurosurg.  2014; 51(2): 243-248]

Key Words: Benign focal epilepsy, psychometric assessment, event related potentials, contingent negative variation.
