Diagnoses of attention hyperactivity disorder among children have increased dramatically in recent years, rising 22 percent from 2003 to 2007, according to the Centers for Disease Control and Prevention. But many experts believe that this may not be the epidemic it appears to be.
Many children are given a diagnosis of A.D.H.D., researchers say, when in fact they have another problem: a sleep disorder, like sleep apnea. The confusion may account for a significant number of A.D.H.D. cases in children, and the drugs used to treat them may only be exacerbating the problem.
“No one is saying A.D.H.D. does not exist, but there’s a strong feeling now that we need to rule out sleep issues first,” said Dr. Merrill Wise, a pediatric neurologist and sleep medicine specialist at the Methodist Healthcare Sleep Disorders Center in Memphis.
The symptoms of sleep deprivation in children resemble those of A.D.H.D. While adults experience sleep deprivation as drowsiness and sluggishness, sleepless children often become wired, moody and obstinate; they may have trouble focusing, sitting still and getting along with peers.
The latest study suggesting a link between inadequate sleep and A.D.H.D. symptoms appeared last month in the journal Pediatrics. Researchers followed 11,000 British children for six years, starting when they were 6 months old. The children whose sleep was affected by breathing problems like snoring, mouth breathing or apnea were 40 percent to 100 percent more likely than normal breathers to develop behavioral problems resembling A.D.H.D.
