MONDAY, Nov. 23 (HealthDay News) -- Children whose mothers smoked during pregnancy or who were exposed to lead have more than double the risk of having attention-deficit hyperactivity disorder (ADHD) as other children, new research shows.
And with exposure to both cigarettes and lead, the chances of having ADHD soared. Children whose mothers smoked during pregnancy and whose blood showed signs of lead exposure had eight times the risk of having ADHD.
