Treating sleep apnea helps children behave

According to this article, treating sleep apnea helps children behave.

Obstructive sleep apnea makes it nearly impossible to get a good night's sleep. Imagine air stopping in your throat, prompting you to choke anobesity, AHDH, and heart disease. If that weren't reason enough to seek treatment, maybe this will: A recent study conducted by the University of Michigan Health System found remedying a child’s sleep apnea improves their behavior, no matter if they have a low or high IQ.

"When a clinician sees a pediatric patient who has a problem in school, they ask about sleep," said Dr. Ronald Chervin, neurologist and director of the University of Michigan Sleep Disorders Center, in a statement. "We wondered, in high-performing children, do we still need to worry about snoring or sleep issues?"

Chervin and his colleagues recruited 147 children between the ages of 3 and 12 who were scheduled to undergo an adenotonsillectomy — a procedure that removes the patient’s tonsils and adenoids. Adenotonsillectomy is usually performed when children are suspected of having obstructive sleep apnea, which is characterized by enlarged tonsils and adenoids that stop children from breathing up to ten seconds throughout the night.

Researchers conducted sleep tests that monitored brain wave patterns, eye movements, heart rhythm, muscle activity, airflow out the nose and mouth, chest movements, and snoring. They then asked parents to grade their child's behavior with regard to inattention, hyperactivity, social problems, and perfectionism. The results showed children from both low and high IQ groups experienced similar behavioral improvements when they were reevaluated six months after the adenotonsillectomy.

"Regardless of intellectual level, we can expect to see some behavioral improvement along with better sleep," said Dr. Bruno Giordani, a professor of neurology, psychiatry, psychology, and nursing. "Once behavior improves, attention in school improves, and emotional ability and behavioral and impulsivity control improve."

Although children with high IQs were included in the study, identifying children with high IQs and obstructive sleep apnea is difficult in practice because they don't typically show problems with school performance. Spotting a child who is struggling from a lack of good sleep is a lot tougher than an adult who almost certainly will appear to be tired the next day, if not outright complain about it. Children, on the other hand, often react to a lack of sleep by being hyperactive the next day.

"Children with obstructive sleep apnea are fidgeting and not able to stay on task, because they're doing anything they can to stay awake," said Dr. Seockhoon Chung. "Even when those behavioral problems are minimal, improvement is still possible."

Studies have shown improved behavioral problems related to sleep apnea is imperative to ensuring these behaviors don't carry over into teenage years. A study presented at SLEEP 2012 found children with untreated obstructive sleep apnea suffered more from long-term behavioral problems, including aggression, hyperactivity, difficulty in controlling their behavior, and many other social and behavioral problems.

Sleep apnea in children and behavioral problems

This article explains the link between sleep apnea in children and behavioral problems such as ADD and ADHD.

Attention deficit hyperactivity disorder (ADHD) is the most-commonly diagnosed behavioral disorder in children. The current standard of care for youngsters with attention deficit disorder (ADD) and ADHD is prescription medication such as Adderall, Ritalin and Dexadrine. These medications may have concerning side effects such as reduced height and weight, cardiovascular effects, tics, evidence of carcinogenic and reproductive effects, and substance abuse.

Sadly, many of these children are being misdiagnosed. A child who exhibits behavior problems or difficulty paying attention at home or school may actually be suffering from another disorder, an underlying undiagnosed sleep-related breathing disorder known as obstructive sleep apnea (OSA).

Dr. Stephen Sheldon, professor of pediatrics at Northwestern University School of Medicine and director of the Sleep Medicine Center says, “There are a number of sleep disorders that if looked at, an attention deficit problem can be identified. If you take a large number of children that have attention deficit and you evaluate them for sleep-disordered breathing, about a fifth to a quarter of those youngsters will have pediatric obstructive sleep apnea.”

He continues, “The most important aspect of evaluating a child for ADHD or other attention problems is to do a sleep evaluation in every single child. One hundred percent of these children need a sleep evaluation.”

...

Nighttime symptoms of youngsters with sleep-related breathing disorders are: snoring, bruxism, mouth breathing, bed wetting, frequent awakenings, nightmares, insomnia and physically restless sleep. Resulting daytime symptoms and findings are neurocognitive impairment, headaches, hyperactivity, behavioral issues, tiredness and poor school performance.

Lack of sleep and/or poor-quality sleep affects a child’s physical and emotional health, cognitive function, behavior and academic success. Parents, teachers, counselors or anyone concerned with the growth and development, academic performance, or health and well-being of a child must have greater awareness of sleep issues. Sleep screening and interventions to improve sleep must become part of every child’s routine clinical exam.

Early diagnosis and treatment of pediatric OSA is vital if we are going to have an impact on the epidemic of OSA in our country. Today, research indicates that one in four adults in this country suffers from obstructive sleep apnea. Of these, 80 percent remain undiagnosed and untreated. Although there is a growing awareness and therefore an increase in the number of adults treated for OSA, the key is prevention and early intervention.

A YouTube video, “Finding Conner Deegan,” tells a mother’s story of her struggling son who was labeled a “troubled child” early in his life. Having exhausted every resource, potential diagnosis and treatment known to his medical community, there appeared no other options. But through his mother’s perseverance, love, relentless search and striving to understand her son, her prayers were answered. Conner, in fact, suffered from undiagnosed pediatric OSA. He simply couldn’t breathe!

Parents, teachers, counselors and doctors need to be made aware of the need to screen children for sleep-related breathing disorders and understand the significant role timely diagnosis and thorough treatment play in the healthy growth and development of our children.

Sleep issues in children with mental health diagnoses

Sleep issues are common among children with mental health diagnoses, and may go undiagnosed due to the co-existing conditions.

Sleep difficulties, particularly problems falling asleep, are common among toddlers and preschoolers with mental health issues, according to a new study.

"Sleep problems in young children frequently co-occur with other behavioral problems, with evidence that inadequate sleep is associated with daytime sleepiness, less optimal preschool adjustment, and problems of irritability, hyperactivity and attention," said the study's leader, John Boekamp, clinical director of the pediatric partial hospital program at Bradley Hospital in Providence, R.I.

However, he said, sleep disorders may be unrecognized and underdiagnosed in young children, particularly when behavioral or emotional problems are present.

The study, published online in Child Psychiatry & Human Development, involved 183 children aged 6 years or younger receiving outpatient treatment for psychiatric problems. The researchers examined the prevalence of sleep disorders among these children and the nature of the sleep problems.

"The most common sleep difficulties reported nationally for toddlers and preschoolers are problems of going to bed, falling asleep and frequent night awakenings. Collectively, these problems are referred to as behavioral insomnias of childhood," said Boekamp in a hospital news release.

Recognized sleep disorders, particularly sleep onset insomnia, were more common than expected, the researchers found. Overall, 41 percent of children in the study met the criteria to diagnose a sleep disorder.

Sleep problems were most common in kids with disruptive behavior, and attention, anxiety and mood problems, the researchers found.

Early sleep problems could not only be the result of behavioral and emotional problems, but could also contribute to them, the researchers noted.

"Essentially, these young children might be caught in a cycle, with sleep disruption affecting their psychiatric symptoms, and psychiatric symptoms affecting their sleep-wake organization," said Boekamp. "It is important for families to be aware of how important sleep is to the behavioral adjustment and well-being of young children."

Sleep problems can complicate treatment for challenging behaviors, such as aggression and attention and mood problems. Daytime sleepiness and fatigue can make these problems even worse, the study's authors noted.

"This study is a great reminder that it's critical for mental health providers working with young children and their families to ask about children's sleep," said Boekamp.

"Simple questions about children's sleep patterns, including how long it takes a child to fall asleep at night and how frequently a child awakens after falling asleep, may yield important information that is relevant to clinical care, even when sleep problems are not the primary focus of treatment," he explained.

Drinking before pregnancy may indicate behavior problems in children

A study found that women who drink before pregnancy are more likely to have children with behavioral problems.

Risk drinking before pregnancy can increase the risk of the development behavioral problems in toddlers. This comes from a new study using data from the Norwegian Mother and Child Cohort Study (MoBa). Early intervention to help and support mothers and their children could help to prevent these problems from developing into long term behavioral problems.

In the study, several screening questions were used to measure maternal drinking behavior; how many drinks were needed to feel high, had others irritated or hurt them by criticizing their alcohol consumption, had they felt they ought to drink less alcohol, and had they ever drunk alcohol in the morning to relieve a hangover.

The study shows that risk drinking before pregnancy increases the risk of early behavior problems among children. According to the researchers, risk drinking may be due to other associated risk factors in maternal behavior such as anxiety, depression or attention deficit hyperactivity disorder (ADHD), which also are known to have an impact on child behavioral problems.

Prenatal exposure to alcohol is known to affect the developing fetus, with adverse cognitive and behavioral effects. Most risk drinking women therefore limit or stop drinking alcohol while pregnant. Paternal risk drinking is also known to have a negative impact on toddler behavior. This is the first study to study the impact of risk drinking before pregnancy. The results could not be explained by alcohol consumption during pregnancy and after birth.

"This increased risk for behavioral problems in the child is probably not due to the risk drinking per se, but rather to the general mental health and lifestyle of some of the mothers. Risk drinking behavior before pregnancy may indicate that these families could need closer follow-up and support during the early years of the child's life" says Ann Kristin Knudsen, primary author of the article published in the European Child and Adolescent Psychiatry journal.

The study considered both internalizing and externalizing behavioral problems among the toddlers. Internalizing behavioral problems include anxiety, inhibition, withdrawal or depression. Restlessness, defiance, fighting and lack of remorse are examples of externalizing behavior. These are known risk factors for behavior problems in childhood and adolescence, which sometimes continue into adulthood.

Epilepsy surgery can improve children's behavior and mood

Children who undergo specific types of epilepsy surgery have shown to have their mood and behavior to be substantially improved post-surgery.

Certain types of epilepsy surgery led to significant improvements in children's mood and behavioral problems, a researcher said.

Children undergoing left-side resections were more likely to show neuropsychiatric symptom improvements if the target was in the frontal rather than the temporal lobe, while those having right-side surgeries had improvements irrespective of site, said Elizabeth Andresen, PhD, of theCleveland Clinic's Neurological Institute.

Relatively little improvement was seen in mood or behavioral symptoms in children with left-side temporal lobe seizure foci, but the baseline symptom burden was relatively lower to begin with, she said at a press briefing prior to her platform talk at the annual meeting of the American Epilepsy Society.

Andresen noted that neuropsychiatric complaints are extremely common in children with epilepsy. Previous studies have found a nearly five-fold increase in risk of such disorders in such children compared with the general population, and a 2.5-fold risk increase relative to children with other chronic diseases.

Some other studies have found improvements in such symptoms following epilepsy surgery, she said, but they had not examined whether the benefit varied with the surgical site, either by hemisphere or by lobe.

The study was based on a combination of child self-reports and parental assessments using standard instruments, administered before and after 100 surgeries in pediatric epilepsy patients. Of 54 left hemisphere resections, 38 were in the temporal lobe and 16 in the frontal lobe; of 46 right-sided surgeries, 26 were in the temporal lobe and 20 in the frontal.

At patients' neuropsychological evaluation after surgery, 83% were seizure-free. At last follow-up an average of 5 years after surgery, 57% of the cohort still had not had a recurrence of seizures. Patients were from 5 to 16 years of age (mean 11) at surgery, with mean duration of epilepsy symptoms of 5.3 years (SD 3.6).

In children with left-side resections, normalized T-scores for anhedonia, social anxiety, and withdrawn/depressed symptoms declined significantly for those with frontal lobe targets compared with temporal lobe patients.

• Anhedonia: 59 pre, 50 post in frontal lobe; 50 pre, 50 post in temporal lobe (P=0.009)
• Social anxiety: 59 pre, 42 post in frontal lobe; 49 pre, 48 post in temporal lobe (P=0.001)
• Withdrawn/depressed: 59 pre, 55 post in frontal lobe; 58 pre, 50 post in temporal lobe (P=0.039)

For right-sided surgeries, targets in both lobes were associated with declines in a "social problems" composite. Normalized T-scores for this measure declined from 69 to 64 with frontal lobe procedures and from 59 to 56 with temporal lobe resections (P=0.001 with respect to time and P=0.005 between groups).

Depression was significantly relieved after surgery when Andresen and colleagues analyzed the entire 100-patient cohort. Among the 25 patients rated as depressed prior to surgery, 64% were no longer depressed at follow-up.

Similarly, anxiety resolved in 60% of children with presurgical symptoms, Andresen reported.

She noted that 6% of children who had no symptoms of depression before surgery developed symptoms by the time of follow-up, and 11% of the cohort showed new postsurgical anxiety. But she said rates of emergent depression and anxiety symptoms were similar in a group of epileptic children not undergoing surgery who underwent the same neuropsychological testing.

Irregular bedtime can mean behavioral problems in children

Irregular bedtimes in children can lead to sleep deprivation which can harm a child's brain and cause children to have behavioral issues.

Researchers from UCL have found that children with irregular bedtimes are more likely to have behavioral difficulties.

The study, which is published in the journal Pediatrics, found that irregular bedtimes could disrupt natural body rhythms and cause sleep deprivation, undermining brain maturation and the ability to regulate certain behaviours.

Professor Yvonne Kelly (UCL Epidemiology & Public Health), said: "Not having fixed bedtimes, accompanied by a constant sense of flux, induces a state of body and mind akin to jet lag and this matters for healthy development and daily functioning."

"We know that early child development has profound influences on health and wellbeing across the life course. It follows that disruptions to sleep, especially if they occur at key times in development, could have important lifelong impacts on health."

Analysing data from more than 10,000 children in the UK Millennium Cohort Study, the team collected bedtime data at three, five and seven years, as well as incorporating reports from the children's mothers and teachers on behavioral problems.

The study found a clear clinical and statistically significant link between bedtimes and behavior as irregular bedtimes affected children's behavior by disrupting circadian rhythms, leading to sleep deprivation that affects the developing brain.

As children progressed through early childhood without a regular bedtime, their behavioural scores -- which included hyperactivity, conduct problems, problems with peers and emotional difficulties -- worsened. However, children who switched to a more regular bedtime had clear improvements in their behaviour.

Professor Kelly said: "What we've shown is that these effects build up incrementally over childhood, so that children who always had irregular bedtimes were worse off than those children who did have a regular bedtime at one or two of the ages when they were surveyed.

"But our findings suggest the effects are reversible," continued Professor Kelly. "For example, children who change from not having to having regular bedtimes show improvements in their behaviour."

Irregular bedtimes were most common at the age of three, when around one in five children went to bed at varying times. However, by the age of seven, more than half the children went to bed regularly between 7.30 and 8.30 pm. Children whose bedtimes were irregular or who went to bed after 9 pm came from more socially disadvantaged backgrounds, and this was factored into the study findings.

Professor Kelly said: "As it appears the effects of inconsistent bedtimes are reversible, one way to try and prevent this would be for health care providers to check for sleep disruptions as part of routine health care visits. Given the importance of early childhood development on subsequent health, there may be knock-on effects across the life course. Therefore, there are clear opportunities for interventions aimed at supporting family routines that could have important lifelong impacts."

Preschoolers who sleep less have more behavior issues

A study shows that toddlers and preschoolers who do not get enough sleep have more behavior problems than those who get adequate sleep.

Four-year-olds with shorter than average sleep times have increased rates of "externalizing" behavior problems, reports a study in the July Journal of Developmental & Behavioral Pediatrics, the official journal of the Society for Developmental and Behavioral Pediatrics. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

"Preschool children with shorter nighttime sleep duration had higher odds of parent-reported overactivity, anger, aggression, impulsivity, tantrums, and annoying behaviors," according to the new research by Dr. Rebecca J. Scharf of University of Virginia, Charlottesville, and colleagues. They recommend that parents and health care providers discuss steps to improve sleep habits for preschool-age children with behavior problems.

Shorter Sleep Times, More Behavior Problems

The researchers analyzed parent responses from a nationally representative study of approximately 9,000 children, followed from birth through kindergarten age. When the children were four years old, nighttime sleep duration was estimated by asking the parents what time their child typically went to bed and woke on weekdays.

On a standard child behavior questionnaire, parents rated their child on six different "externalizing" behavior problems such as anger and aggression. (Externalizing behavior problems are outward behaviors, distinguished from "internalizing" problems such as depression and anxiety.) The relationship between sleep duration and behavior scores was assessed, with adjustment for other factors that might affect sleep or behavior.

The average bedtime was 8:39 pm and wake time 7:13 am, giving a mean nighttime sleep duration of about 10½ hours. Eleven percent of children were considered to have "short sleep duration" of less than 9¾ hours (calculated as one standard deviation below the average).

On the child behavior questionnaire, 16 percent of children had a high score for externalizing behavior problems. Behavior problems were more common for boys, children who watched more than two hours of television daily, and those whose mothers reported feeling depressed.

After adjustment for other factors, "Children in the shortest sleep groups have significantly worse behavior than children with longer sleep duration," Dr Scharf and colleagues write. The effect was greatest for aggressive behavior problems, which were about 80 percent more likely for children with nighttime sleep duration of less than 9¾ hours.

Shorter sleep times were also associated with 30- to 46-percent increases in rates of the other externalizing behaviors studied, including overactivity, anger, impulsivity, tantrums, and annoying behaviors. In a linear analysis, as sleep duration increased, troubling behaviors decreased.

Previous studies in smaller groups of children have identified shorter nighttime sleep duration as a risk factor for behavior problems in preschool children. The average 10½-hour sleep time in this nationally representative sample is less than in studies performed in past decades, and less than currently recommended for four-year-olds.

The new results, along with other recent studies, add to the evidence that preschoolers who sleep less will have more behavior problems, including disruptive behaviors like aggression and overactivity. Although the study can't draw any conclusions about causality, "there is good reason to believe that short nighttime sleep duration leads to externalizing behaviors," the researchers write.

Dr Scharf and coauthors recommend that doctors and health care providers ask about bed and wake times when talking to parents about young children with behavior problems. They add, "Advocating for regular sleep habits, healthy sleep hygiene, and regular bedtime routines may be helpful for young children."

Sleep Apnea in Children leads to Learning Complications

Obstructive sleep apnea in children leads to learning complications such as ADHD, behavioral problems, or learning problems.

New research confirms the relationship between obstructive sleep apnea in children and ADHD, as well as other behavioral and cognitive problems. Children with sleep apnea, a common type of disordered breathing during sleep, are more likely to have difficulties with learning and attention.

Obstructive sleep apnea, a type of sleep-disordered breathing (SDB), affects about 2 percent of children in the United States, according to the American Academy of Sleep Medicine. The link between obstructive sleep apnea in children and ADHD (attention-deficit hyperactivity disorder) has been previously established, but this is the first sleep study to use self-reports in assessing children's adaptive behavior, or ability to adapt to new situations.

The study, published in the April edition of the journal SLEEP, analyzed sleep and cognitive data from 263 Arizona children enrolled in the Tucson Children's Assessment of Sleep Apnea Study (TuCASA) over five years. The children, all between 6 and 11 years old, completed overnight sleep studies and standard series of neurobehavioral tests at the beginning and end of the 5-year period. Their parents also answered questionnaires about the children's behavior.

The sleep studies divided the children into four groups: those who never had sleep-disordered breathing, those who had it the first time but not the second, those who had it only the second time (new onset), and those who had it both times (persistent).

The results showed that children with new onset sleep apnea were at least four times as likely to have behavioral problems- the likelihood rose to six times higher if they had persistent sleep apnea.

The children with obstructive sleep apnea were more likely to have parents reporting problems with their hyperactivity, attention, communication abilities, self-care, and ability to adapt to new situations. They were also likely to be suffering academically, with grades of C or lower in school.

"This study provides some helpful information for medical professionals consulting with parents about treatment options for children with SDB that, although it may remit, there are considerable behavioral risks associated with continued SDB," said Dr. Michelle Perfect, the study's lead author and assistant professor in psychology at the University of Arizona in Tucson.

Obstructive sleep apnea is a major cause of snoring, occurring when soft tissue in the back of the throat relaxes too much during sleep and collapses into the airway. This cuts off oxygen intake, and the temporary suffocation sends a signal to the brain to wake up immediately. When sleep apnea is especially severe, it can interrupt sleep hundreds of times throughout the night- depriving the brain of oxygen and causing exhaustion the next day.

Children with sleep-disordered breathing generally have larger tonsils and adenoids than other children their age, and most children with sleep apnea have a history of loud snoring. Effective treatment options for children include the surgical removal of the tonsils and adenoids or the use of continuous positive airway pressure (CPAP) therapy.

The Arizona researchers say in their study that most children with sleep apnea have larger tonsils and adenoids than those without it, and are much more likely to snore loudly. Tonsillectomies can provide effective sleep apnea treatment, and so can continuous positive airway pressure (CPAP therapy).

Perfect said in a statement that obstructive sleep apnea in children typically declines into adolescence, but that "taking a wait and see approach is risky" for parents who are worried about their children's cognitive and behavioral development.

"School personnel should also consider the possibility that SDB contributes to difficulties with hyperactivity, learning and behavioral and emotional dysregulation in the classroom."

The New York Times suggests that ADHD-related learning problems may often result from obstructive sleep apnea in children, and that the symptoms could be better treated with sleep improvements than with stimulant medications like Adderall and Ritalin, which can actually increase sleep deprivation.

High-Tech Gadgets Can Help Diagnose and Study Autism

New technology claims that it can help diagnose autism in children, and also help study autism.

Researchers in Georgia Tech's Center for Behavior Imaging have developed two new technological tools that automatically measure relevant behaviors of children, and promise to have significant impact on the understanding of behavioral disorders such as autism.

One of the tools -- a system that uses special gaze-tracking glasses and facial-analysis software to identify when a child makes eye contact with the glasses-wearer -- was created by combining two existing technologies to develop a novel capability of automatic detection of eye contact. The other is a wearable system that uses accelerometers to monitor and categorize problem behaviors in children with behavioral disorders.

Both technologies already are being deployed in the Center for Behavior Imaging's (CBI) ongoing work to apply computational methods to screening, measurement and understanding of autism and other behavioral disorders.

Children at risk for autism often display distinct behavioral markers from a very young age. One such marker is a reluctance to make frequent or prolonged eye contact with other people. Discovering an automated way to detect this and other telltale behavioral markers would be a significant step toward scaling autism screening up to much larger populations than are currently reached. This is one goal of the five-year, $10 million "Expeditions" project, funded in fall 2010 by the National Science Foundation under principal investigator and CBI Director Jim Rehg, also a professor in Georgia Tech's School of Interactive Computing.

The eye-contact tracking system begins with a commercially available pair of glasses that can record the focal point of their wearer's gaze. Researchers took video of a child captured by a front-facing camera on the glasses, worn by an adult who was interacting with the child. The video was then processed using facial recognition software available from a second manufacturer. Combine the glasses' hard-wired ability to detect wearer gaze with the facial-recognition software's ability to detect the child's gaze direction, and the result is a system able to detect eye contact in a test interaction with a 22-month-old with 80 percent accuracy. The study was conducted in Georgia Tech's Child Study Lab (CSL), a child-friendly experimental facility richly equipped with cameras, microphones and other sensors.

"Eye gaze has been a tricky thing to measure in laboratory settings, and typically it's very labor-intensive, involving hours and hours of looking at frames of video to pinpoint moments of eye contact," Rehg said. "The exciting thing about our method is that it can produce these measures automatically and could be used in the future to measure eye contact outside the laboratory setting. We call these results preliminary because they were obtained from a single subject, but all humans' eyes work pretty much the same way, so we're confident the successful results will be replicated with future subjects."

The other new system, developed in collaboration with the Marcus Autism Center in Atlanta and Dr. Thomas Ploetz of Newcastle University in the United Kingdom, is a package of sensors, worn via straps on the wrists and ankles, that uses accelerometers to detect movement by the wearer. Algorithms developed by the team analyze the sensor data to automatically detect episodes of problem behavior and classify them as aggressive, self-injurious or disruptive (e.g., throwing objects).

Researchers first developed the algorithms by putting the sensors on four Marcus clinic staff members who together performed some 1,200 different behavior instances, and the system detected "problem" behaviors with 95 percent accuracy and classified all behaviors with 80 percent accuracy. They then used the sensors with a child diagnosed along the autism spectrum, and the system detected the child's problem-behavior episodes with 81 percent accuracy and classified them with 70 percent accuracy.

"These results are very promising in leading the way toward more accurate and reliable measurement of problem behavior, which is important in determining whether treatments targeting these behaviors are working," said CSL Director Agata Rozga, a research scientist in the School of Interactive Computing and co-investigator on the Expeditions award. "Our ultimate goal with this wearable sensing system is to be able to gather data on the child's behavior beyond the clinic, in settings where the child spends most of their time, such as their home or school. In this way, parents, teachers and others who care for the child can be potentially alerted to times and situations when problem behaviors occur so that they can address them immediately."

"What these tools show is that computational methods and technologies have great promise and potential impact on the lives of many children and their parents and caregivers," said Gregory Abowd, Regents' Professor in the School of Interactive Computing and a prominent researcher in technology and autism. "These technologies we are developing, and others developed and explored elsewhere, aim to bring more effective early-childhood screening to millions of children nationwide, as well as enhance care for those children already diagnosed on the autism spectrum."

Both technologies were presented in early September at the 14th ACM International Conference on Ubiquitous Computing (Ubicomp 2012). Among the other devices under study at CSL are a camera/software system that can track children's facial expressions and customized speech analysis software to detect vocalization patterns.

Loud Snoring in Young Children May Predict Behavior Issues

A new study claims that young children and preschoolers that snore may predict behavior issues in the future.

Persistent and loud snoring in young children is associated with problem behaviors, according to a new study published online in Pediatrics.

These behaviors include hyperactivity, depression and inattention, according to Dean Beebe, PhD, director of the neuropsychology program at Cincinnati Children's Hospital Medical Center and lead author of the study.

"The strongest predictors of persistent snoring were lower socioeconomic status and the absence or shorter duration of breastfeeding," says Dr. Beebe. "This would suggest that doctors routinely screen for and track snoring, especially in children from poorer families, and refer loudly-snoring children for follow-up care. Failing to screen, or taking a 'wait and see' approach on snoring, could make preschool behavior problems worse. The findings also support the encouragement and facilitation of infant breastfeeding."

The study is believed to be the first to examine the relationship between the persistence of snoring and behavior problems in preschool-age children. Persistent, loud snoring occurs in approximately one of every 10 children.

Dr. Beebe and colleagues at Cincinnati Children's studied 249 children. The researchers surveyed the children's moms about their kids' sleep and behaviors. The study showed that children who snored loudly at least twice a week at the age of 2 and 3 had more behavior problems than children who either don't snore or who snored at 2 or 3 but not at both ages.

"A lot of kids snore every so often, and cartoons make snoring look cute or funny. But loud snoring that lasts for months is not normal, and anything that puts young kids at that much risk for behavioral problems is neither cute nor funny," says Dr. Beebe. "That kind of snoring can be a sign of real breathing problems at night that are treatable. I encourage parents to talk to their child's doctor about loud snoring, especially if it happens a lot and persists over time."

Infant breastfeeding, especially over longer periods of time, seemed to protect children against persistent snoring, even after taking into account other factors, including family income.

A window of opportunity for intervention? Early identification of sleep problems in preschool children with behavioral problems.

This is a very interesting article. It is well known that children develop cognitive problems when they have sleep apnea. IQ drops. Neuronal in the hippocampus  is lost.  However,  there may be a window to intervene early  before the evolution of cognitive problems.  


This article suggests that children with behavioral problems should be screened for sleep apnea early before cognitive problems are noted. JR

Sleep-disordered breathing in preschool children is associated with behavioral, but not  cognitive, impairments.

Abstract

BACKGROUND:

Sleep-disordered breathing (SDB) has been associated with impaired cognitive and behavioral function in school children; however, there have been limited studies in preschool children when the incidence of the disorder peaks. Thus, the aim of this study was to compare cognitive and behavioral functions of preschool children with SDB to those of non-snoring control children.

METHODS:

A clinical sample of 3-5year-old children (primary snoring [PS], n=60; mild obstructive sleep apnea syndrome [OSAS], n=32; moderate/severe [MS] OSAS, n=24) and a community sample of non-snoring control children (n=37) were studied with overnight polysomnography. Cognitive performance and behavioral information were collected.

RESULTS:

Children with PS and mild OSAS had poorer behavior than controls on numerous measures (p<.05-p<.001), and on some measures they had poorer behavior than the MS OSAS group (p<.05). In contrast, all groups performed similarly on cognitive assessment. Outcomes related more to sleep than respiratory measures.

CONCLUSIONS:

SDB of any severity was associated with poorer behavior but not cognitive performance. The lack of significant cognitive impairment in this age group may have identified a "window of opportunity" where early treatment may prevent deficits arising later in childhood.
