Abstract
Fetal growth retardation is an important perinatal riskfactor. We try to use evoked EEG responses (ER) for evaluation of cerebral function in this riskgroup.
MATERIAL AND METHOD: 50 SGA newborns were examined. Visual (VER) and somatosensory (SER) cortical ER as well as auditory brainstem responses (BSER) were recorded and computer averaged.
RESULTS: In 70% of the SGA newborns some immature features of VER were observed - inadequate response patterns, increased exhaustibility and/or prolonged latency. The same differenties were found in SGA twins in pairs where the other sibling was AGA.SER showed similar changes only in 25% of cases. BSER were altered only exceptionally.
CONCLUSION: There is no direct relation between birthweight and brain development which is generally dependent on gestational age. Nevertheless in many SGA newborns are cerebral functions less mature and more vulnerable than in AGA infants.
