The sleep apnea and ADHD connection: Our children bear the scars

People lobbying for gun control may want to consider another culprit in the post-Newtown search for the answer to our unfathomable questions. In Adam Lanza, with his classic adenoidal face structure, have we overlooked a possible root cause as simple as the very air we breathe … or more accurately, don't breathe? Failure to free a compromised child's breathing, usually through tonsil and adenoid removal, can have tragic repercussions which extend beyond the life of that individual. Parents today tend to view tonsillectomies with skepticism. Aren't we smarter now than when tonsils were routinely removed for a few stubborn sore throats? What about our president's well-publicized implications that surgeons fall prey to financial incentives to remove tonsils, limbs, and anything else that can be severed? Shouldn't we be wary?RELATED | Kids' sleep-related breathing problems and behaviorial sleep problems appear linked Evidence is mounting that if a child's tonsils are causing him or her to snore or breathe abnormally, there are more serious things to be wary of than the knife. The politicization of medical decisions is particularly regrettable fallout from Washington's debate over how to control one-fifth of our economy. After President Obama made his "cash for tonsils" gaffe at a health-care overhaul rally, The American College of Surgeons reacted strongly, and rightly so. Their official statement made it clear that the College still thinks its members take the Hippocratic Oath seriously, and are not knife-happy because of the current reimbursement schedules President Obama promises to convert into a greed-deterring system: "That remark (that a surgeon's decision to remove a child's tonsils is based on the desire to make a lot of money) was ill-informed and dangerous, and we were dismayed by the characterization of the work surgeons do." Aside from the insult to physicians, who still rank No. 2 on Forbes' "Most Respected Professions" list, is it a big deal to raise public doubt about the necessity of tonsillectomies and the motives of those we have traditionally trusted to do the right thing for our children?Changing trends in tonsillectomy Let's start by noting that two generations ago, tonsillectomies were routine, not due to snoring, but due to throat infections. Tonsillectomies were an inpatient procedure, and moer than one million American children had their tonsils removed in the 1950's alone! At that time, 90% of tonsillectomies were performed because of recurrent infections, but superior antibiotics and a generally cautionary approach to surgery reversed the tide. Today, only 20% of the tonsillectomies performed are due to recurrent infection. Eighty percent are due to sleep-disordered breathing, which is the spectrum that extends from primary snoring, which is often benign, through obstructive sleep apnea (OSA). (1)The brain remembers every insult The message that surprisingly hasn't been shouted from the rooftops is that we have significant evidence that sleep-related breathing disorders are associated with cognitive and behavioral impairment in children (which improve after tonsillectomy). What, then, if OSA is ignored and the child grows up with these "cognitive and behavioral impairments" becoming firmly rooted? Do we then have an adult with ADHD, with anxiety or depression, and often some very severe anger issues?RELATED |Special alert to dental professionals: Bruxism is caused by stress ... the stress of suffocating to death! It is safe to say that ADHD has been routinely misdiagnosed, undertreated, and overtreated, and the medical and psychological communities are still stabbing in the dark about root causes and defining physiological characteristics. The closest we have come to finding these is through PET scans, which have demonstrated abnormal glucose uptake patterns in the brains of symptomatic individuals. Why that happens and whether the reduced glucose uptake causes symptoms or simply coexists with them is as yet unclear. One thing that is clear is that a child diagnosed with ADHD will exhibit symptoms that mimic the very natural consequences of other infirmities or unmet physiologic needs — like quality sleep. The adult with ADHD is different from the child in that the pattern of behavior --> response to behavior --> negative reinforcement of self-image has been in place since childhood. Chronic inability to engage in social banter, listen attentively, keep to a calendar and be prompt, plan and organize ... all these basic necessities of a civilized lifestyle can be daunting to the adult with ADHD, and the reactions from the world are often emotionally debilitating.10 Symptoms of adult ADHD

9. Angry outbursts
10. Prioritizing issues
    

So tonsils are connected with mental health? Strong correlations have been established and causal relationships are beginning to emerge from the research, but aside from this, there is something very fundamental we know: breathing matters. Oxygen matters. Acute lack of oxygen is a death sentence, a chronic shortage of oxygen is going to lead to a suboptimal life, and the little throats of children have disproportionately large organs around which to negotiate the air they need. Here's something else we do know: 10% of children snore regularly, and it is estimated that 10% to 30% of these children have obstructive sleep apnea. (2,3,4,5) But wait — it gets worse! Untold numbers of children suffer from other upper airway restrictions that mimic OSA but which are not considered a problem by many people in the medical community. In total, that is a lot of children to put at risk for permanent damage from dysfunctional breathing. In children who have moderate to severe OSA, the airway is so compromised that the body is in continual "fight or flight" mode, as the primitive brain struggles for oxygen. A child will snore, repeatedly stop breathing, and then arouse to recover, only to fall back into the cycle. Not only is there an oxygen deficit, but the "fight or flight" mode causes surges of sympathetic system hormones (adrenaline and cortisol) to be delivered throughout the bloodstream. In the short term, the child will simply be exhausted, "fuzzy," distracted by day. Over time, however, as the barrage of hormones habitually attacks the nervous system and organs, permanent changes take place. Anxiety, depression, and other psychological disorders are among the consequences of this unremitting hormonal onslaught.Disappearing ADHD In fact, researchers are accruing evidence that much of the behavior we call ADHD is a result of chronic struggle for oxygen from obstructive sleep apnea, and a significant percentage of the time, this is something that can be resolved by tonsil removal. Multiple studies have demonstrated that ADHD symptoms subside substantially postsurgery, and some studies even indicate that 20% to 30% of the participants who were diagnosed with ADHD became completely asymptomatic for ADHD. (6) If OSA is caught and treated early, we can mitigate damage and the toll that living with ADHD takes on the psyche. The "adenoidal face" reflects childhood struggle Any dentist, orthodontist, or physician can recognize the characteristics of what is called "adenoid facie" — a face that has developed an abnormally long, narrow bone structure due to chronic mouth-breathing over the growth years. The "dumb look" may belie an intelligence that is often dwarfed or subverted by years of others' negative responses to a tired, forgetful, distracted demeanor. Loneliness, rejection, failure in others' eyes, eventually converts to anger — at self or others. The brain is permanently damaged by the struggle with airway incompetence. An indelible mark is left. Generally, only the person's close relationships suffer from the damage, but sometimes a missed diagnosis may have had repercussions way beyond that small circle. While we will never know the etiology of Adam Lanza's tragic rampage, he exhibits the classic "adenoidal face," and one can't help but wonder if he wasn't, as a child, victim to his own nighttime battles for air, and what kind of impact that made on his mental state over time.Spare the knife, risk the outcome Tonsillectomies are still painful and still carry the attendant risks of major surgery. However, the risk of morbidity or misplaced trust in a surgeon are very low, and to let fear blind us to the enormous benefits children receive from relieved airways, improved oxygenation, peaceful sleep, and potential prevention of long-term mental health problems is far riskier.What if my child snores or exhibits ADHD symptoms? A one to two night polysomnic sleep test at a certified sleep laboratory will enable a sleep medicine professional to rule out sleep disordered breathing or recommend surgery (primary recommendation for children), CPAP, or oral device treatment.
