Adolescents with a childhood diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) are more likely to have current and lifetime sleep problems and disorders, regardless of the severity of current ADHD symptoms, says a new study.
In the study, which has been published in the May 1 issue of the journal SLEEP, authors suggest that mental health professionals should screen for sleep problems and psychiatric comorbidities among all adolescents with a childhood diagnosis of ADHD.
Results indicate that adolescents with a childhood diagnosis of ADHD, regardless of persistent ADHD were more likely to have current sleep problems and sleep disorders such as insomnia, sleep terrors, nightmares, bruxism and snoring.
Of the total sample, 17 percent of children with ADHD were currently suffering from primary insomnia, versus 7 percent of controls; lifetime primary insomnia occurred in 20 percent of children with ADHD, compared to 10 percent of controls.
Nightmare disorder affected 11 percent of children with ADHD and lifetime nightmare disorder affected 23 percent, versus 5 and 16 percent of controls. The presence of at least one psychiatric comorbid condition increases the risks for insomnia and nightmares.
According to principal investigator Susan Shur-Fen Gau, MD, PhD, associate professor at the College of Medicine and Public Health, National Taiwan University, symptoms and consequences of ADHD and sleep problems in children often overlap. Some primary sleep disorders are found to be associated with inattention, hyperactivity, behavioral problems and impaired academic performance, which are often mistaken for symptoms of ADHD.
