Abstract:
Magnetic resonance imaging was conducted on six children and
adolescents with fetal alcohol syndrome and seven matched normal
controls. Detailed volumetric analyses demonstrated significant
reductions in the cerebral vault, basal ganglia, and diencephalon in the
children with fetal alcohol syndrome, compared with control children. In
addition, the volume of the cerebellar vault was smaller than controls
in 4 of the 6 children with fetal alcohol syndrome, although the group
difference did not reach significance. When the basal ganglia were
divided into the caudate and lenticular nuclei, both of these regions
were significantly reduced in the children with fetal alcohol syndrome.
Finally, when the overall reduction in brain size was controlled, the
proportional volume of the basal ganglia and, more specifically, the
caudate nucleus was reduced in the children with fetal alcohol syndrome.
These results may relate to behavioral findings in both humans and
animals exposed to alcohol prenatally
