Smoking during pregnancy may interfere with brain development. New animal research shows maternal smoking affects genes important in the formation and action of a fatty brain substance called myelin that insulates brain cell connections.
The research was presented at Neuroscience 2010, the annual meeting of the Society for Neuroscience, held in San Diego.
The finding may explain why the children of mothers who smoked during pregnancy are more likely to develop attention deficit hyperactivity disorder, depression, autism, drug abuse, and other psychiatric disorders. "Myelin deficits have been previously observed in adults with various psychiatric disorders," said Ming Li, PhD, of the University of Virginia, who directed the study.
