We have analysed electroencephalographic findings, brain CT findings and evoked potentials findings in cerebral palsied patients from 5 months to 19 years old. Neuromuscular type distribution in order was 77.0% of spastic type, 11.5% of mixed type and 9.9% of athetoid type. Topographic distribution of spasitc type was 53.1% of spastic diplegia, 33.5% of spastic tetraplegia and 12.4% of spastic hemiplegia. Fraquency of possible risk factors in order was 30.6% of prematurity, 28.6% of low birth weight, and 19.8% of perinatal asphyxia. The indicence of seizure was 36.5% . Abnormal findings of brain CT scan and EEG were 56.9% and 46.7%, respectively. In addition, abnomal VEP(visual evoked potential) and BAEP(brainstem auditory evoked potential) findings were 7.9% and 9.9% respectively.
