Dr. Virginia Delaney-Black, Wayne State University School of Medicine, is quoted extensively in a story about her research findings recently published in the Journal of Developmental and Behavioral Pediatrics. Delaney-Black and her colleagues found that boys exposed to cocaine in their mothers\' womb were much more hyperactive than those with no prenatal cocaine exposure. Boys who experienced persistent cocaine exposure were also more likely to have delayed speech and language development or other problems in central processing, as well as problems with their motor skills and abstract thought than were their peers who experienced little or no exposure to the drug. These findings were not true of the girls involved in the study, the report indicates.
