Young adults who were born very prematurely, but without any serious brain impairments, may still not be as mentally sharp as their peers, a small study published Monday suggests. Finnish researchers found that of 208 young adults they tested, the half born at a very low weight -- less than 3.3 pounds -- generally had lower scores on some measures of memory, attention and other mental skills.
