[Visual evoked potentials in 8-year-old children. Normal values and applications in pediatric neurology].
In the framework of a research program on the prevalence and incidence of cerebral dysfunction and child psychiatric disorder, EEG and flash-evoked responses were recorded in more than 300 8-year-old children. Automatic determination of the following parameters: latencies and amplitudes of N1, P2, N2, N3, N4; area of the complex N1P2N2, average absolute amplitude, asymmetry coefficients and Pearson correlation between the responses of both hemispheres. Normative data for these parameters obtained from a randomized sample (N = 148), mean values and intersextile ranges are reported. The random sample was compared with two other groups of children (8 years old): children with minimal brain dysfunction (N = 55) and/or psychiatric disorder (N = 82). Both groups showed significantly longer latencies in comparison to the random normative sample.
