Objective: The present study was undertaken to determine the value of developmental assessment, multimodality evoked potentials, brain magnetic resonance image (MRI) and electroencephalography (EEG) and to identify correlations between each evaluation.

Method: Developmental assessments such as Bayley scales of infant development and Vineland social maturity scale, brain MRI, EEG and evoked potentials findings were evaluated in 45 children with spastic cerebral palsy to assess the developmental level and abnormalities of the anatomical structure of the brain and to elucidate the relationship between the test methods.

Results: 1) Mean mental developmental index (MDI) and psychomotor developmental index (PDI) were 69.6 and 68.6, respectively and mean Vineland social maturity quotient (SQ) was 76.1 and there was a significant correlation between the MDI, PDI, and SQ in cerebral palsied children. 2) Abnormal findings of brain MRI and EEG were found in 73.3% and 44.4% of the cases, respectively. 3) There was significant correlation between findings of brain MRI, auditory evoked potentials, visual evoked potentials, median somatosensory evoked potentials and social quotient.

Conclusion: Developmental assessment, multimodality evoked potentials, EEG, and brain MRI would be a useful method to evaluate the maturity of brain and estimate the level of development.

Objective: The present study was undertaken to evaluate the findings of multimodality evoked potentials, brain MRI and EEG in cerebral palsy children and to identify the correlations between these findings.

Method: We examined Brain MRI, EEG and evoked potentials including visual evoked potentials(VEPs), brainstem auditory evoked potentials(BAEPs) and somatosensory evoked potentials(SSEPs) in 80 cerebral palsy children.

Results: 1) Abnormal findings of brain MRI and EEG were 79.4% and 81% respectively.

2) Abnormal responses of VEPs and BAEPs were 28.1% and 18.8%.

3) In the median and tibial nerve SSEPs, abnormal responses were 14.6% and 28.6%. Abnormal findings of the tibial nerve SSEPs were more frequent than the median nerve SSEPs.

4) In children with spastic hemiplegia, the abnormal SSEPs were much greater in the affected limb than unaffected limbs.

5) There was a significant correlation between the SSEP abnormalities and brain MRI or EEG abnormalities in cerebral palsy children.

Conclusion: The data obtained in this study would be helpful for identifying and assessing the central nervous system deficits of cerebral palsy children.
