CDC Reports That Half of U.S. Children Diagnosed with ADHD Received Diagnosis By Age 6

A new study published in JAACAP found that an estimated two million more children in the U.S. have been diagnosed with attention-deficit/hyperactivity disorder (ADHD) between 2003-04 and 2011-12. One million more U.S. children were taking medication for ADHD between 2003-04 and 2011-12.
ADHD is one of the most common neurobehavioral disorders of childhood. It often persists into adulthood. Children with ADHD may have trouble paying attention and/or controlling impulsive behaviors. Effective treatments for ADHD include medication, mental health treatment, or a combination of the two. When children diagnosed with ADHD receive proper treatment, they have the best chance of thriving at home, doing well at school, and making and keeping friends.

  •  The parent-reported prevalence of a history of an attention-deficit/hyperactivity disorder (ADHD) diagnosis by a health care provider among U.S. school-aged children increased from 7.8% in 2003 to 11% in 2011, an increase of 42% in less than a decade.
  •  In 2011, the median age of ADHD diagnosis was approximately 6 years of age, but children reported by their parents as having more severe ADHD were diagnosed earlier.
  •  The percentage of US school-aged children with a parent-report of current medication treatment for ADHD increased from 4.8% in 2007 to 6.1% in 2011, an increase of 27% in approximately 4 years.
  •  More U.S. school-aged children were receiving ADHD treatment in 2011 than in 2007, but nearly 1 in 5 with current ADHD were not receiving either medication.

Diagnosing the Wrong Deficit - A Great Read about ADD-ADHD & Sleep from the NYTimes


Diagnosing the Wrong Deficit




IN the spring of 2010, a new patient came to see me to find out if he had attention-deficit hyperactivity disorder. He had all the classic symptoms: procrastination, forgetfulness, a propensity to lose things and, of course, the inability to pay attention consistently. But one thing was unusual. His symptoms had started only two years earlier, when he was 31.
Though I treat a lot of adults for attention-deficit hyperactivity disorder, the presentation of this case was a violation of an important diagnostic criterion: symptoms must date back to childhood. It turned out he first started having these problems the month he began his most recent job, one that required him to rise at 5 a.m., despite the fact that he was a night owl.
The patient didn’t have A.D.H.D., I realized, but a chronic sleep deficit. I suggested some techniques to help him fall asleep at night, like relaxing for 90 minutes before getting in bed at 10 p.m. If necessary, he could take a small amount of melatonin. When he returned to see me two weeks later, his symptoms were almost gone. I suggested he call if they recurred. I never heard from him again.
Many theories are thrown around to explain the rise in the diagnosis and treatment of A.D.H.D. in children and adults. According to the Centers for Disease Control and Prevention, 11 percent of school-age children have now received a diagnosis of the condition. I don’t doubt that many people do, in fact, have A.D.H.D.; I regularly diagnose and treat it in adults. But what if a substantial proportion of cases are really sleep disorders in disguise?
For some people — especially children — sleep deprivation does not necessarily cause lethargy; instead they become hyperactive and unfocused. Researchers and reporters are increasingly seeing connections between dysfunctional sleep and what looks like A.D.H.D., but those links are taking a long time to be understood by parents and doctors.
We all get less sleep than we used to. The number of adults who reported sleeping fewer than seven hours each night went from some 2 percent in 1960 to more than 35 percent in 2011. Sleep is even more crucial for children, who need delta sleep — the deep, rejuvenating, slow-wave kind — for proper growth and development. Yet today’s youngsters sleep more than an hour less than they did a hundred years ago. And for all ages, contemporary daytime activities — marked by nonstop 14-hour schedules and inescapable melatonin-inhibiting iDevices — often impair sleep. It might just be a coincidence, but this sleep-restricting lifestyle began getting more extreme in the 1990s, the decade with the explosion in A.D.H.D. diagnoses.
A number of studies have shown that a huge proportion of children with an A.D.H.D. diagnosis also have sleep-disordered breathing like apnea or snoring, restless leg syndrome or non-restorative sleep, in which delta sleep is frequently interrupted.
One study, published in 2004 in the journal Sleep, looked at 34 children with A.D.H.D. Every one of them showed a deficit of delta sleep, compared with only a handful of the 32 control subjects.
A 2006 study in the journal Pediatrics showed something similar, from the perspective of a surgery clinic. This study included 105 children between ages 5 and 12. Seventy-eight of them were scheduled to have their tonsils removed because they had problems breathing in their sleep, while 27 children scheduled for other operations served as a control group. Researchers measured the participants’ sleep patterns and tested for hyperactivity and inattentiveness, consistent with standard protocols for validating an A.D.H.D. diagnosis.
Of the 78 children getting the tonsillectomies, 28 percent were found to have A.D.H.D., compared with only 7 percent of the control group.  
Even more stunning was what the study’s authors found a year after the surgeries, when they followed up with the children. A full half of the original A.D.H.D. group who received tonsillectomies — 11 of 22 children — no longer met the criteria for the condition. In other words, what had appeared to be A.D.H.D. had been resolved by treating a sleeping problem.
But it’s also possible that A.D.H.D.-like symptoms can persist even after a sleeping problem is resolved. Consider a long-term study of more than 11,000 children in Britain published last year, also in Pediatrics. Mothers were asked about symptoms of sleep-disordered breathing in their infants when they were 6 months old. Then, when the children were 4 and 7 years old, the mothers completed a behavioral questionnaire to gauge their children’s levels of inattention, hyperactivity, anxiety, depression and problems with peers, conduct and social skills.
The study found that children who suffered from sleep-disordered breathing in infancy were more likely to have behavioral difficulties later in life — they were 20 to 60 percent more likely to have behavioral problems at age 4, and 40 to 100 percent more likely to have such problems at age 7. Interestingly, these problems occurred even if the disordered breathing had abated, implying that an infant breathing problem might cause some kind of potentially irreversible neurological injury.

Risk of ADHD higher in children whose parents are depressed or violent

A study shows that young children whose parents are depressed or are involved in partner violence are more likely to develop ADHD by age 6.


Preschoolers whose parents reportdepression and intimate partner violence may be more likely to develop attention-deficit/hyperactivity disorder (ADHD) by the age of 6, new research suggests.
And young children with depressed moms may be more likely to receive prescription drugs to treat behavioral and mental health issues down the road.
"Our study indicates that preschoolers who are diagnosed with ADHD are more likely to have been exposed to both intimate partner violence and parental depression within the first three years of life than their peers not exposed to either risk factor," said study author Dr. Nerissa Bauer, an assistant professor of pediatrics at Indiana University School of Medicine, in Indianapolis.
"There has been increasing awareness that certain psychosocial risk factors can impact the behavioral presentation of children at very young ages," she said. Still, not all children who are exposed to maternal depression and intimate partner violence will develop ADHD, she noted.
"There are other factors that can be associated with a child's higher likelihood of being diagnosed with ADHD, including a family history of ADHD," Bauer explained.
ADHD symptoms can include impulsiveness, hyperactivity and difficulty focusing.Kids with ADHD may have difficulty in school, holding down jobs and sustaining relationships. They are also at greater risk for alcohol or substance abuse, depression and anxiety disorders. Treatment typically involves medication and behavioral modifications.
"Pediatricians and family practitioners know to routinely screen for the presence of these psychosocial risk factors because of the potential negative effects on the child," Bauer said. "Families who experience intimate partner violence will need help, not only to make sure the victims stay safe from physical harm, but there [are] also psychological effects."
The study, which appeared online Feb. 4 in the journal JAMA Pediatrics, included more than 2,400 children who were 3 years old. Parents who brought them to four different pediatric community clinics filled out questionnaires regarding their personal history of depression and domestic violence while in the pediatricians' waiting room.
Fifty-eight caregivers reported a history of intimate partner violence and depression before their child turned 3. In addition, 69 reported a history of intimate partner violence and 704 had symptoms of depression during this time frame. Close to 66 percent of the parents reported neither depression nor intimate partner violence. Children who were exposed to intimate partner violence and/or parental depression were four times more likely to be diagnosed with ADHD by the age of 6.
What's more, 2.9 percent of kids whose parents reported depression received prescription drugs to treat behavioral and mental health issues, compared with 1.6 percent of children whose parents did not report a history of depression. Medications included those that treat anxiety, depression and sleep problems.
While the study showed an association, it did not prove a cause-and-effect link between intimate partner violence and/or maternal depression and likelihood of anADHD diagnosis.
Experts said the findings make sense, but more study is needed.
"This study adds to the already robust literature revealing that early life experiences can have profound effects on brain development," said Dr. Michael Duchowny, a pediatric neurologist at Miami Children's Hospital. "While heredity is known to play a strong role in the expression of ADHD symptoms, the study further suggests that additional environmental factors operating during the formative years of brain maturation are also significant."
New York City-based child psychoanalyst Dr. Leon Hoffman said the new findings make sense. "Unquestionably, intimate partner violence and maternal depression have a profound effect on children," he said.
Exactly how to deal with this is another story, said Hoffman, who is the co-director of the New York Psychoanalytic Society's Pacella Parent Child Center. "This is a public health problem that needs a lot of funds if reasonably effective programs are to be developed," he noted.
Dr. Rachel Klein, professor of child and adolescent psychiatry at NYU Langone Medical Center in New York City, said the study shows an association based on how parents answered certain questions, but it can't say how, or even if, maternal depression and intimate partner violence predict a child's risk of ADHD.
"If parents are worried, ask the pediatrician to evaluate your child for possible ADHD or refer the child to a mental health professional," she added.

Sleep Study Abnormalities in Children With Attention Deficit Hyperactivity Disorder

Wow - 24% with obstructive sleep apnea! JR

Sleep Study Abnormalities in Children With Attention Deficit Hyperactivity Disorder

Section of Neurology, Department of Pediatrics, St. Christopher's Hospital for Children, Drexel University College of Medicine, Philadelphia, Pennsylvania
Received 8 May 2008; accepted 5 September 2008.
The study objective was to describe polysomnographic findings in children with attention deficit hyperactivity disorder (ADHD) with diverse sleep problems. Polysomnographic data were retrospectively analyzed for 33 children (age 3-16 years) with ADHD who had sleep studies performed for diverse sleep complaints. Eight patients (24%) had obstructive sleep apnea, 10 (30%) had periodic limb movements of sleep, 8 (24%) had upper airway resistance syndrome, and 5 (15%) had obstructive hypoventilation. The ADHD group showed decreased sleep efficiency, increased arousal index, increased wake after sleeponset, decreased oxygen saturation nadir, and increased snoring, compared with control subjects. Compared with ADHD children without sleep disordered breathing, those who had sleep disordered breathing were significantly more obese and had more sleep architectural abnormalities (including increased sleep latency, increased rapid eye movement latency, increased wake after sleep onset, and increased arousal index with more oxygen desaturations), although total sleep time and sleep efficiency were not significantly different. Sleep disordered breathing and periodic limb movements of sleep appear to be common among children with ADHD who have symptoms of disturbed sleep.
