The terms ADD and ADHD are often used interchangeably to refer to a brain disorder marked by an ongoing pattern of inattention and/or hyperactivity that interferes with functioning or development. Children who have ADHD symptoms tend to demonstrate difficulty with concentration and can be disruptive at home and school. The problem generally occurs equally among males and females. Although behavior issues, an inability to concentrate and hyperactivity may also be associated with sleep disorders, ADHD is currently the medically accepted term for these neurological conditions . When ADHD symptoms resemble some of the same symptoms as sleep-related breathing disorders, a misdiagnosis and ineffective treatments may result if the sleep factor is not at least considered. Signs of sleep disorders may be sleeping in unusual positions, snoring loudly, and interrupted, intermittent breathing during sleep with snorts, gasps or waking up after a pause in breathing; these symptoms can be accompanied by heavy sweating, dark circles under the eyes, and headaches. It’s not surprising that when behavior becomes disruptive at school, daycare or home, ADHD, not sleep quality, is suspected. However, when the child is also grumpy, aggressive, hyperactive, unable to focus, falling asleep or daydreaming in school or at home and grades become problematic, doctors will often recommend a sleep test to rule out SRBD.
