We determined metabolite profile in spastic diplegic children compared to controls in left basal ganglia of brain in using proton magnetic resonance spectroscopy in correlation with age and gender. Twenty-four patients with spastic diplegia and twenty-six healthy children were examined. The relative concentrations of N-acetylaspartate, choline, and myoinositol were measured in relation to creatine and different combinations of metabolites within 8-cm3 brain voxel. Children with spastic diplegia showed reduced ratios of N-acetylaspartate/creatine, N-acetylaspartate/ choline, and N-acetylaspartate/myoinositol in the basal ganglia compared to the control group. Patients and controls subjects demonstrated a significant age-dependent increase in N-acetylaspartate/creatine, N-acetylaspartate/choline in the basal ganglia. No gender-dependent difference was shown in children with cerebral palsy for all tested metabolite ratios. Gender-related differences because of increased ratio N-acetylaspartate/choline in girls in controls were detected. These results indicate that maturation of brain exists in cerebral palsy and healthy children to a higher degree in healthy children.

Key Words: cerebral palsy • metabolites • proton magnetic resonance spectroscopy
