A new video-game therapy has shown promise in treating attention-deficit hyperactivity disorder in children, according to a new study.
"This study is designed to assess whether the video-game therapy works -- specifically, to see if it improves attention -- and the video game did just that," said Dr. Scott Kollins, a professor in psychiatry and behavioral sciences at Duke University and co-author of the study, which was done in collaboration with 20 U.S. research institutions.
Symptoms of ADHD include difficulties in sustaining attention, impulsivity and restlessness that results in functional impairment.
About 4.4% of people in the U.S. and 3.4% globally have been diagnosed with ADHD, the most common childhood mental condition and one that often lasts into adulthood.
About 8% to 12% of school-aged children have ADHD, which also is more common in boys than in girls. Nearly three-quarters of those diagnosed see the condition last into adulthood.
ADHD typically is treated first with medications. Untreated ADHD, experts have said, often creates problems in familial, social and educational situations.
Successful ADHD treatments also tend to include therapeutic components, such as cognitive-behavioral therapy, which retrains people in how to think and how to act in particular situations.
While the combination of medication and behavioral therapy has proven effective, Kollins and his colleagues pointed out that not everyone has access to these treatments. Additionally, many parents are often reluctant to put children on medications.
The study focused on video-game therapy suggests that it can help lessen ADHD symptoms in children with minimal side effects.
Researchers developed a video game designed to improve attention in children by creating multitasking challenges adapted to their individual skillsets. In the study, 350 children ages 8 to 12 who had ADHD but hadn't yet been prescribed drugs were divided into two groups -- one that used the newly created video-game therapy, and another that played a regular video game.
The children in each group spent four weeks playing their assigned game for 25 minutes per day, five days per week. Data showed that the children who played the new video-game therapy had significant improvements in attention scores compared with the control group.
A similar study that examined children who still were taking medication showed similar results. Side effects of the video-game therapy included headaches and frustrations.
"The number of side effects in the trial was very low, especially compared to a pharmacologic trial," Kollins said. "Also the intervention is easy to access, as opposed to a qualified provider, which is difficult to access in many areas and communities. This video game is something that can be downloaded."
Dr. Neha Chaudhary, a child and adolescent psychiatrist at Massachusetts General Hospital and Harvard Medical School, and a co-founder of Brainstorm, Stanford's Lab for Mental Health Innovation, largely agreed with Kollins' assessment.
"This study shows promise for digital interventions," Chaudhary added. "While they may not be replacements for medications, they certainly might augment clinical care in a new way. With child psychiatrists in short supply, these tools might be helpful for kids to use in the interim while waiting to get plugged into mental health care."
Behavioral strategies can be particularly helpful for children with ADHD, "especially where medications cannot be used," Chaudhary explained. "While the gold standard of treatment for ADHD in childhood is still stimulants -- and the benefits of such treatments are clear -- it is exciting to see new, innovative interventions emerge."
