EEG Response to Photic Stimulation in 120 Normal Children

Paroxysmal EEG response to photic stimulation was found in 25.8% of 120 children, mainly at school age, although less than 6% presented deviations from normality in the EEG before visual stimulation had been performed. It is warned against precipitated diagnostic conclusions from such responses in children before the age of 15. The results support the view that paroxysmal response on visual stimulation is largely dependent on constitutional factors and factors in relation to brain immaturity causing biological lability.
