Teachers and doctors should keep in mind a child's relative age when considering whether he has an attention deficit, finds a new study in the journal Lancet Psychiatry.

Researchers from the University of Nottingham in England analyzed all children born in Finland from 1998 through 2011, including 6,136 diagnosed with attention-deficit hyperactivity disorder by age 10. They found that boys born between September and December of each year were 26 percent more likely to be diagnosed with ADHD than boys born in thefirst three months of the same year; girls born at the end of the year were 31 percent more likely to be identified with ADHD.
