Breathing problems during sleep may affect mental development in infants and young children
Forwarded from Dr. Len Saputo:
From Mike: This is HUGE.
I believe that food allergies are the primary reason for breathing difficulties in children. I have observed that food allergies are not considered with most allopathic assessments. The below approach to sleep disturbances sets up a marketplace for getting children to get surgery, drugged and/or use mechanical breathing devices called CPAP, BIPAP etc.
What I have observed in the adult market for this process is that the devices help some a great deal and others not at all AND no one is addressing the person's ability to improve their breathing and often the nutrition which are in most cases the primary causes for having the breathing problem in the first place.
That means that they will probably stay on those drugs, or receive surgery or mechanical breathing devices that will last the rest of their lives. Do we want this to happen to our children as well? In the light of all that please continue.
Children who have problems breathing during sleep tend to score lower on tests of mental development and intelligence than do other children their age, according to two studies funded by the National Institutes of Health (NIH). Both studies appear in the October issue of Journal of Pediatrics.
The first study, funded by the National Institute of Child Health and Human Development (NICHD), found that at one year of age, infants who have multiple, brief breathing pauses (apnea) or slow heart rates during sleep scored lower on mental development tests than did other infants of the same age.
The second study was funded primarily by the National Heart, Lung, and Blood Institute (NHLBI). Results show that 5-year-old children who had frequent snoring, loud or noisy breathing during sleep, or sleep apneas observed by parents scored lower on intelligence, memory, and other standard cognitive tests than other children their age. They were also more likely to have behavioral problems.
"The findings from these studies support other research that has shown that breathing problems during sleep are associated with serious health consequences in children," said Carl E. Hunt, M.D., director of the NIH National Center on Sleep Disorders Research (NCSDR).
"However, at this point, we don't know if the sleep problems during these episodes cause the decline in test scores or if the sleep episodes and the lower test scores are both related to some common underlying mechanism."
More than 10 percent of young children have habitual snoring, the mildest form of sleep-disordered breathing (SDB). One to three percent of children have obstructive sleep apnea, a more severe form of SDB in which breathing stops briefly and repeatedly during sleep.
SDB is thought to be more common in toddlers and younger children than in older children because the younger ones are more likely to have large tonsils and adenoids, which can briefly block the airways in the back of the throat during sleep.
African American children are twice as likely to develop SDB compared to white children. Children who are overweight or obese are also more likely to develop SDB.
In the first study, researchers evaluated 256 full-term and preterm infants at one year of age with a standardized test that measured physical and mental development. The infants were part of the multi-center Collaborative Home Infant Monitoring Evaluation (CHIME) study. The CHIME study sought to identify factors that could put infants at risk for sudden infant death syndrome (SIDS).
Participants included healthy infants as well as those at increased risk of SIDS because they had a history of prematurity, a life-threatening event during sleep, or a sibling who had died from SIDS. The infants' breathing, heart rates, and blood oxygen levels were monitored electronically at home for the first 4-6 months of age.
The researchers found that infants who totaled more than five episodes of abnormally slowed heart rate or apnea during the period they were monitored scored lower on the mental development test at one year of age than did infants who experienced fewer or no such episodes.
The episodes were often associated with drops in oxygen levels. The lower mental development scores persisted even after data were adjusted to correct for other factors known to affect mental development in preterm infants.
The study also found that full-term infants who experienced the abnormal episodes scored lower on the tests than did other full term infants, according to Hunt, the lead author, who conducted the research while at the Medical College of Ohio in Toledo.
The second study involved 205 children at 5 years of age. Researchers at Boston University School of Medicine compared neurocognitive function and behavior of 61 children with SDB symptoms to 144 children without symptoms.
Symptoms of SDB, as reported by parents, included frequent snoring; heavy, loud, or noisy breathing during sleep; or observed apneas during sleep. An overnight sleep test (polysomnogram) was also performed to objectively measure the severity of SDB.
The study found that children with SDB symptoms scored lower on standard tests measuring executive function (attention and planning), memory, and general intelligence. These children also had significantly more behavioral problems than children without SDB symptoms, based on parental survey scores.
"One of the more remarkable findings in this study was that the neurocognitive effects were significant even among the children who had mild symptoms of sleep-disordered breathing but no actual sleep apneas," said Daniel Gottlieb, M.D., M.P.H., lead author of the study. "Parents need to be aware that their child's snoring could signal serious problems."
The mild SDB symptoms associated primarily with snoring in these children result in frequent arousals and fragmented sleep, leading to poor sleep quality and hence to sleep deprivation.
Today's findings are similar to other studies of children and adults that link poor sleep or sleep deprivation to problems with school (or job) performance, difficulties with memory and concentration, increased risk of injuries, and trouble controlling impulses, emotions, and behavior, especially in children.
"Unfortunately, the effects of poor sleep are often overlooked or misinterpreted in children. Rather than appearing sleepy like adults who are sleep deprived, children may in fact seem to be more active or even hyperactive," comments Hunt.
In an accompanying editorial, Hunt notes that brain development is not complete until at least late childhood, and hence children may be uniquely vulnerable to SDB symptoms and their consequences, especially if such symptoms begin during infancy or early childhood. Brain areas, such as the prefrontal cortex, which regulate executive function, might be particularly susceptible to damage from SDB, writes Hunt.
In addition, other researchers have reported that the effects of SDB appear to have long-term consequences for children. For example, a University of Louisville study found that young children who snored loudly and frequently were more likely to have lower grades in middle school - even several years after the breathing problem was treated or resolved.
"These two new studies point to the need for parents and pediatricians to be on the watch for what might appear to be less serious breathing problems in their babies and young children when they sleep," notes Hunt.
"If we can identify these children before the effects on mental development have occurred, the challenge then will be to identify possible ways to intervene and prevent any reduced potential for doing their best in school."
Scientists have not yet determined safe and effective ways to reduce cardiorespiratory episodes in infants. In children, however, treatment for SDB typically involves having the tonsils and adenoids surgically removed.
In more severe cases, or for children who cannot have surgery, a machine known as continuous positive airway pressure (CPAP), which forces air into the air passages while the patient is sleeping, can be as effective in children as it is in adults with sleep apnea.
The health consequences associated with SDB in children are gaining increasing recognition. In April 2002, the American Academy of Pediatrics established clinical practice guidelines on obstructive sleep apnea in children.
The guidelines call for all children to be screened for snoring and for children diagnosed with obstructive sleep apnea to be treated.

Nothing about nutrition that Mike could find. Adenotonsillectomy is the first line of treatment for most children. What is wrong with these so called health professionals.

Adenotonsillectomy Resolves Obstructive Sleep Apnea for Children
SURE it will. That is until something else surfaces that is worse than the apnea.
Children can have their diets changed and be taught to develop their breathing. You develop your breathing and show your child how.
