Yes, Girls Get ADHD, Too

Why attention deficit hyperactive disorder is so often overlooked in girls.

Neil Peterson, a transportation specialist in Seattle, knew something was "not quite right" with his bright, sociable daughter Kelsey when she was in elementary school. "It took her so long to learn to read," Peterson says. "She was not hyperactive, but she had tremendous distractibility and an inability to follow through and stay with something." Kelsey's teachers told Peterson not to worry, and he listened.

On the surface, Kelsey was no different from other kids her age -- all young students, at one point or another, can become easily bored or distracted, flit from one thing to the next, and forget their homework. But if these behaviors are persistent, they might be a sign of ADHD, which affects 3% to 7% of all school-age children, or about one to three kids in every classroom.

Sometimes girls like Kelsey are missed. Though boys are diagnosed at about three times the rate of girls, that doesn't necessarily mean the disorder is more common in boys, says ADHD expert Harlan Gephart, MD, clinical professor of pediatrics at the University of Washington School of Medicine in Seattle.

Rather, asks Gephart, "Is it just not as recognized in girls?"

The short answer is yes, according to researchers. One national study found that the majority of parents and teachers thought ADHD to be more common in boys, who they believed had more behavior problems. Almost half of the teachers who took part in this study also reported that they had trouble recognizing the signs of ADHD in girls.

An Australian study found that even when parents and teachers acknowledged the disorder in girls, they were less likely to recommend that the girls get extra assistance. That's because they thought it wouldn't help them as much as it would boys.

"The big problem with ADHD in girls is that it presents itself differently," Gephart says. "Boys are just more obvious."

ADHD Symptoms in Girls

Of the three traits that define ADHD -- hyperactivity, impulsiveness, and inattentiveness -- the first two are thought to be more descriptive of boys and the last of girls, though there's certainly crossover, according to Gephart.
