Prenatal meth exposure linked to abnormal brain development
Date:4/16/2009

ST. PAUL, Minn. A first of its kind study examining the effects of methamphetamine use during pregnancy has found the drug appears to cause abnormal brain development in children. The research is published in the April 15, 2009, online issue of Neurology, the medical journal of the American Academy of Neurology.

"Methamphetamine use is an increasing problem among women of childbearing age, leading to an increasing number of children with prenatal meth exposure," said study author Linda Chang, MD, with the John A. Burns School of Medicine, University of Hawai`i at Mānoa in Honolulu. "But until now, the effects of prenatal meth exposure on the developing brain of a child were little known."

For the study, brain scans were performed on 29 three- and four-year-old children whose mothers used meth while pregnant and 37 unexposed children of the same ages. The MRI scans used diffusion tensor imaging to help measure the diffusion of molecules in a child's brain, which can indicate abnormal microscopic brain structures that might reflect abnormal brain development.

The scans showed that children with prenatal meth exposure had differences in the white matter structure and maturation of their brains compared to unexposed children. The children with prenatal meth exposure had up to four percent lower diffusion of molecules in the white matter of their brains.

"Our findings suggest prenatal meth exposure accelerates brain development in an abnormal pattern," said Chang. "Such abnormal brain development may explain why some children with prenatal meth exposure reach developmental milestones later than others."

Studies have shown that prenatal meth exposure can lead to increased stress and lethargy and poorer quality of movement for infants.

"While we don't know how prenatal meth exposure may lead to lower brain diffusion, less diffusion of molecules in white matter typically reflects more compact
