This study investigated the relationship between intellectual functioning and brain volume in children with a developmental delay under the age of five years. Methods Intellectual functioning, intracranial volume, total brain volume, and ventricular volume were assessed in 13 children. Pearson correlation coefficients were calculated. Results There was a significant correlation of 0.74 between intellectual functioning and total brain volume, after controlling for intracranial volume. A significant negative correlation was found between intellectual functioning and total ventricular volume (r=-0.77). There was no correlation between intellectual functioning and total brain volume or intracranial volume. Conclusions These results suggest that there may be relative brain volume loss related to poor intellectual functioning in young children with idiopathic developmental delay. binnenwerk 170 x 240 21-08-2006 21:53 Pagina 75Read More
