Like Boys, Girls with ADHD at Risk for Other Mental Disorders
A new study from the University of California, Los Angeles suggests girls with attention-deficit hyperactivity disorder are at higher risk than girls without ADHD for multiple mental disorders.
Researchers said that for girls, mental issues may lead to cascading problems such as abusive relationships, teenage pregnancies, poor grades, and drug abuse.
According to the federal Centers for Disease Control and Prevention, boys are more than twice as likely to be diagnosed with ADHD than girls; they also are at greater risk of co-occurring mental disorders.
The study by University of California, Los Angeles psychologists was said to be the most comprehensive analysis of girls and ADHD that has ever been undertaken. They discovered:
- 37.7 percent of girls with ADHD met criteria for an anxiety disorder, compared with only 13.9 percent of girls without ADHD;
- 10.3 percent of girls with ADHD were diagnosed with depression compared with only 2.9 percent without ADHD;
- 42 percent of girls with ADHD were diagnosed with oppositional defiant disorder, compared with just five percent of girls without it. Oppositional defiant disorder is characterized by angry, hostile, irritable, defiant behavior. To meet the diagnosis for oppositional defiant disorder, a child must display at least four of eight symptoms for at least six months that result in significant academic, social, and family problems;
- 12.8 percent of girls with ADHD were diagnosed with conduct disorder compared with only 0.8 percent without ADHD. Conduct disorder is similar to oppositional defiant disorder, but with more severe behavioral problems, such as committing violent acts, setting fires, and hurting animals.
The findings appear in the journal Pediatrics.
“We knew the girls with ADHD would have more problems than the girls without ADHD, but we were surprised that conduct disorder and oppositional defiant disorder were at the top of the list, not depression or anxiety,” said Steve Lee, senior author of the study.
“These conduct disorders, more than anxiety and depression, predict severe adult impairments, such as risky sexual behavior, abusive relationships, drug abuse, and crime.”
Symptoms of ADHD include being easily distracted, fidgeting, being unable to complete a single task and being easily bored. The disorder occurs in approximately five percent to 10 percent of children in the United States, and figures in many other industrialized countries with compulsory education are comparable, Lee said.
ADHD can begin in pre-school kids and can persist into high school and into adulthood, especially when it’s accompanied by oppositional conduct disorder.
The psychologists analyzed 18 studies of 1,997 girls, about 40 percent (796) of whom had ADHD. Most of the girls were between ages eight and 13. Most ADHD studies focused on boys, or compared girls with ADHD to boys with ADHD, not to girls without ADHD.
ADHD is often harder to detect in girls than in boys because girls with the disorder may appear disengaged, forgetful, or disorganized, and perceived as “spacey” and stay “under the radar” without being referred for assessment and treatment, said lead author Irene Tung.
Investigators suggest a variety of actions for concerned parents.
First, if a child’s negative behavior lasts for months and is adversely affecting her or his social relationships and school performance, then it’s worth having your child evaluated by a psychologist or psychiatrist for ADHD and other mental disorders.
Furthermore, parents of girls with ADHD should carefully monitor signs of disruptive behavior, anxiety and depression, Tung said. “Early management of ADHD and related symptoms will be critical in helping young girls function successfully at school and socially, and feel confident,” she said.
“People tend to think of girls as having higher risk for depression and anxiety disorders, and boys as being more likely to exhibit conduct disorders, but we found that ADHD for girls substantially increases their risk for these conduct disorders,” Tung said.
Researchers say school systems are prepared to help. “In many cases, the school can provide support, including an evaluation by a school psychologist.”
Approximately five to seven percent of elementary school students have oppositional defiant disorder and approximately one to two percent of elementary school students have conduct disorder, Lee said. Fewer girls than boys have these disorders.
The good news, the psychologists said, is that there are effective treatments — some involving pharmaceuticals, and others that involve seeing a therapist, as well as effective parenting strategies to manage the behavior.
“Kids with ADHD need structure and consistency, more than the average child; they need to know the rules and the rules need to be applied consistently,” Lee said.
Lee and Tung recommend that parents provide positive reinforcement for good behavior; this does not have to be monetary. “For some of these kids, getting negative attention may be their only way of getting attention,” Tung said.
“Catch your child being good, and reward that,” Lee said. Children will sometimes react negatively to rewards in the beginning, and parents at that point will often stop, but should continue, he added. “The child’s behavior will often get worse before it gets better.”
Many more children meet the criteria for ADHD than are being treated for it, and many children may benefit from treatment who are not receiving it, Lee said.
