A group of 31 children aged 4-14 was presented with clinical manifestations of febrile convulsions, which after clinical examination, were followed--up in outpatient clinics during 1-12 year period. Together with continuous electroencephalographic monitoring, visual and somatosensory potentials were measured with the aim to stress a diagnostic significance of these neurophysiological methods for cerebral maturation assessment in children with febrile convulsions. Results reveal that electroencephalography (EEG) and somatosensory potentials (SEP) have higher diagnostic sensitivity compared to the visual ones (VEP). In 25 children (80.64%) SEP changes were registered in the form of prolonged central conductivity time (CCT) and EEG revealed changes in the form of slower cerebral activity and posterior theta activities fr. 4-7 Hz (P-O bilaterally) in 10 children (32.26%). Registered SEP changes, particularly prolonged CVP, as well as changes in the form of slower basic cerebral activity or posterior theta rhythm could be explained by slower maturation of some CNS regions. EEG and SEP findings show positive correlation with clinical findings and different diagnostic sensitivity, therefore their use in clinical follow-up of children with febrile convulsions is important.
