      &lt;p&gt;SAN ANTONIO  --  A personalized, online self-management program helped patients with pain syndromes improve coping skills and reduce stress and depression in two studies reported here.&lt;/p&gt;
&lt;p&gt;Patients randomized to the self-management program demonstrated significant improvement in multiple social, emotional, and behavioral outcomes after six months (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01). Improvement in some parameters occurred within one month. A control group that was not exposed to the program showed no significant improvement.&lt;/p&gt;
&lt;p&gt;&quot;Our goal is to help people communicate better with providers, understand better how they can use social support, understand the comorbid conditions, like anxiety and depression, and develop cognitive skills to help get them through their pain episodes,&quot; said Emil Chiauzzi, PhD, of Inflexxion, the Newton, Mass. company that developed the program.&lt;/p&gt;
&lt;p&gt;Although the studies involved patients with migraine or low-back pain, programs are being developed for other types of pain condition, including several forms of neuropathic pain.&lt;/p&gt;
&lt;p&gt;The online program, demonstrated at &lt;a href=&quot;http://www.painACTION.com&quot; mce_href=&quot;http://www.painACTION.com&quot; target=&quot;_blank&quot;&gt;www.painACTION.com&lt;/a&gt;, employs patient-specific information to generate individualized self-management strategies.&lt;/p&gt;
&lt;p&gt;Patient responses to assessments are analyzed by a &quot;recommendation engine,&quot; which produces content recommendations designed to address each patient&apos;s informational and self-management needs.&lt;/p&gt;
&lt;p&gt;Elements on the Web site include multimedia education units, a pain inventory, interactive tools that provide information based on patient-provider communication, and medication risk management.&lt;/p&gt;
&lt;p&gt;&quot;The content on the Web site is focused on teaching people practical skills to manage the behavioral side of pain,&quot; Jonas Bromberg, PsyD, also of Inflexxion, said in an interview.&lt;/p&gt;
&lt;p&gt;Bromberg presented results of a randomized study involving 210 patients, all of whom met International Headache Society diagnostic criteria for migraine, with or without aura.&lt;/p&gt;
&lt;p&gt;Patients assigned to the online program completed at least eight 30-minute session during the first month of the study and at least five more 30-minute sessions during the five-month follow-up period. Patients in the control group continued to receive usual care without exposure to the Web site.&lt;/p&gt;
&lt;p&gt;Participants assigned to the online program had a minimum set of requirements for each session, which were provided at log-in. Follow-up assessments occurred at one, three, and six months.&lt;/p&gt;
&lt;p&gt;The two groups were balanced with respect to sex and headache frequency and severity, the researchers said.&lt;/p&gt;
&lt;p&gt;Bromberg reported that patients assigned to the self-management program demonstrated significant improvement in: &lt;ul&gt; &lt;li&gt;Headache self-efficacy (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01 compared with baseline)&lt;/li&gt; &lt;li&gt;Use of relaxation (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Use of social support (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Pain catastrophizing (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Depression (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05 to &lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Stress (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;Chiauzzi presented results from a randomized study of 209 patients with low-back pain. The design was similar to that of the migraine study, except results were analyzed for between-group differences.&lt;/p&gt;
&lt;p&gt;The results showed significant improvement in the study group versus control group with respect to: &lt;ul&gt; &lt;li&gt;Stress (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Coping (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01)&lt;/li&gt; &lt;li&gt;Social supports (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.05)&lt;/li&gt; &lt;/ul&gt;&lt;/p&gt;
&lt;p&gt;The data showed significant effects of both treatment (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01) and time (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.01) favoring the Web site versus control. Chiauzzi said patients assigned to the Web site had greater mean improvement at posttest, three months, and six months.&lt;/p&gt;
&lt;p&gt;Qualitative analysis suggested that Web site participants had clinically meaningful improvement in depression, anxiety, and stress.&lt;/p&gt;
&lt;p&gt;Additionally, patients in the self-management program reported a 12.3% decrease in pain from baseline, versus 7% in the control group.&lt;/p&gt;
&lt;p&gt;Access to the Web site did not improve physical functioning.&lt;/p&gt;

                     title="Low Serotonin Eyed as Mechanism for SIDS (CME/CE)"
                     score="0.011"
                     href="http://www.medpagetoday.com/Neurology/GeneralNeurology/tb/18262?impressionId=1265793708038"
                     
      Low brainstem levels of serotonin and the enzyme that makes it could underlie sudden infant death syndrome (SIDS), researchers suggested.&lt;br&gt;
&lt;br&gt;In an autopsy study, SIDS cases showed 26% lower serotonin levels in two major components of the medulla&apos;s serotonin system  --  the raph&amp;#233; obscurus (&lt;em&gt;P&lt;/em&gt;=0.05) and paragigantocellularis lateralis (&lt;em&gt;P&lt;/em&gt;=0.04)  --  compared with age-adjusted controls who died from known causes.&lt;br&gt;
&lt;br&gt;These brainstem circuits control breathing, blood pressure, and heart rate during sleep, Hannah C. Kinney, MD, of Children&apos;s Hospital Boston, and colleagues reported in the Feb. 3 issue of the &lt;em&gt;Journal of the American Medical Association&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;A baby with an abnormality in control of these systems might not be able to respond to a life-threatening challenge like asphyxia by rousing from sleep or turning its head the researchers explained.&lt;p&gt;&lt;/p&gt;
&lt;p&gt;SIDS occurs in the &quot;critical first year of life, when homeostatic systems are still maturing,&quot; they noted.&lt;/p&gt;
&lt;p&gt;Mary McClain, RN, MS, of Boston University Medical Center, who counsels families that have lost a baby to SIDS, commented that these findings help establish the biological basis for urging parents to place their babies on their backs to sleep.&lt;/p&gt;
&lt;p&gt;The researchers obtained tissue samples from autopsies of 41 children who died from SIDS, seven who died acutely from known causes (including a car accident, drowning, pneumonia, and unsuspected congenital heart disease), and five who died in the hospital with chronic conditions causing hypoxia-ischemia.&lt;/p&gt;
&lt;p&gt;SIDS cases had mean serotonin levels of 31.4 pmol/mg of protein in the paragigantocellularis lateralis, compared with 40.0 pmol/mg among the controls who died acutely (&lt;em&gt;P&lt;/em&gt;=0.04).&lt;/p&gt;
&lt;p&gt;Levels averaged 55.4 versus 75.5 pmol/mg of protein, respectively, in the raph&amp;#233; obscurus (&lt;em&gt;P&lt;/em&gt;=0.05).&lt;/p&gt;
&lt;p&gt;These abnormalities in the medulla did not appear to involve the catecholamine system. Catecholamine levels were similar between SIDS cases and controls.&lt;/p&gt;
&lt;p&gt;Nor was there evidence for excessive degradation of dopamine or neurotransmitter turnover in SIDS cases, supporting the idea that the key abnormality is reduced synthesis of serotonin, the researchers said.&lt;/p&gt;
&lt;p&gt;Another marker of serotonin function  --  tryptophan hydroxylase (TPH2), the key enzyme involved in synthesis of serotonin  --  also supported this conclusion, with 22% lower levels in the raph&amp;#233; obscurus in SIDS than in controls (&lt;em&gt;P&lt;/em&gt;=0.03).&lt;/p&gt;
&lt;p&gt;Serotonin receptor binding was 29% to 55% lower in three medullary nuclei that receive serotonin projections, notable for a decrease in binding with older age in SIDS cases, but not controls, the researchers noted.&lt;/p&gt;
&lt;p&gt;Given similar findings in three previous investigations, this &quot;may reflect a progressive decrease with age in those infants with the &apos;SIDS abnormality,&apos;&quot; they wrote. Or it&apos;s possible that those with a &quot;stronger abnormality take longer to outgrow the risk period for SIDS and continue to die at older ages,&quot; Kinney&apos;s group wrote.&lt;/p&gt;
&lt;p&gt;Likewise, serotonin receptor binding in infants who died from SIDS was significantly lower in those without known risk factors for SIDS, such as &lt;a href=&quot;http://www.medpagetoday.com/Pediatrics/GeneralPediatrics/17365&quot; mce_href=&quot;http://www.medpagetoday.com/Pediatrics/GeneralPediatrics/17365&quot; target=&quot;_blank&quot;&gt;sleeping face down&lt;/a&gt;, &quot;suggesting that additional risk factors are necessary to precipitate death when the medullary serotonin system is less compromised,&quot; they added.&lt;/p&gt;
&lt;p&gt;Although repetitive apnea and agonal &lt;a href=&quot;http://www.medpagetoday.com/Pulmonology/SleepDisorders/2817&quot; mce_href=&quot;http://www.medpagetoday.com/Pulmonology/SleepDisorders/2817&quot; target=&quot;_blank&quot;&gt;impaired gasping&lt;/a&gt; before death have been reported in some SIDS cases, chronic impaired oxygenation in the hospitalized children in the study produced a very different serotonin pattern than that seen in SIDS.&lt;/p&gt;
&lt;p&gt;Children who died with chronic hypoxia conditions had 55% higher serotonin levels in the raph&amp;#233; obscurus (&lt;em&gt;P&lt;/em&gt;=0.02) and 126% higher levels in the paragigantocellularis lateralis (&lt;em&gt;P&lt;/em&gt;=0.002) than the SIDS cases.&lt;/p&gt;
&lt;p&gt;They also had 640% higher dopamine levels in the raph&amp;#233; obscurus than the SIDS cases (&lt;em&gt;P&lt;/em&gt;=0.006).&lt;/p&gt;
&lt;p&gt;This suggested &quot;that the primary mechanisms underlying serotonin abnormalities in SIDS are not mediated by chronic hypoxia-ischemia,&quot; Kinney&apos;s group wrote.&lt;/p&gt;
&lt;p&gt;The researchers cautioned that their neurotransmitter measurements may have been off somewhat due to prolonged postmortem intervals.&lt;/p&gt;
&lt;p&gt;They also warned that the study was limited by inability to perform these measurements at the synapse in postmortem tissues and by the small sample of controls.&lt;/p&gt;

      &lt;p&gt;Doctor&apos;s Orders&lt;em&gt; is a feature in the collaboration between &lt;/em&gt;MedPage Today &lt;em&gt;and&lt;/em&gt; ABC News&lt;em&gt;. In this monthly segment we explore medical issues of interest to physicians and their patients alike. This month, we look at addiction and addictive behaviors, and what neuroimaging studies have revealed about why it&apos;s so hard to break bad habits. &lt;/em&gt;&lt;/p&gt;&lt;hr&gt;

&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;
&lt;p&gt;&lt;em&gt;&lt;/em&gt;&lt;/p&gt;

&lt;p&gt;By the end of January, many New Year&apos;s resolutions have been tossed out with the leftover holiday cookies. That&apos;s because change is hard  --  and neuroscientists are learning why.&lt;br&gt;
&lt;br&gt;Advances in neuroimaging have enabled researchers to peer inside the brains of addicts and patients with addictive behaviors. They can see in real-time what gets patients hooked: how the brain&apos;s reward system  --  based largely on the neurotransmitter dopamine  --  thirsts for more, while inhibitory control centers experience a system failure.&lt;br&gt;
&lt;br&gt;The pattern is similar across all kinds of behaviors  --  from cocaine and tobacco addiction to overeating. That&apos;s why changing your mind may be the first step toward breaking a habit, but altering the brain&apos;s neural machinery is the real challenge.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Hijacked Pathways&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Drug-taking and other addictive behaviors &quot;hijack&quot; the brain&apos;s reward system, says Petros Levounis, MD, director of the Addiction Institute of New York at St. Luke&apos;s and Roosevelt Hospitals in Manhattan.&lt;/p&gt;
&lt;p&gt;In normal patients, dopamine plays a major role in motivation and reward, surging before and during a pleasurable activity  --  say, eating or sex  --  to make patients want to repeat a behavior that&apos;s crucial to the survival of the species.&lt;/p&gt;
&lt;p&gt;Dopaminergic pathways connect the limbic system, responsible for emotion, with the hippocampus, etching rewarding behaviors into the brain by creating strong, salient memories.&lt;/p&gt;
&lt;p&gt;The problem arises when the memory and the craving to recapture it takes over a person&apos;s life.&lt;/p&gt;
&lt;p&gt;&quot;Imagine what a strong hold these hijacked reward pathways take on our brains and our whole existence when they&apos;re so closely connected, geographically and anatomically speaking, with our memories and our emotions,&quot; Levounis says.&lt;/p&gt;
&lt;p&gt;As the dopamine surge repeats and repeats, it gains speed, but the brakes begin to fail: Normal function in the brain&apos;s frontal lobes, responsible for inhibitory control and executive functioning (read: willpower), tends to decrease in addicts.&lt;/p&gt;
&lt;p&gt;&quot;Ultimately,&quot; Levounis says, &quot;the war on drugs is a war between the hijacked reward pathways that push the person to want to use, and the frontal lobes, which try to keep the beast at bay. That is the essence of addiction.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Similar Patterns&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;These neural pathways have been well studied in the brains of hardcore addicts. Now, researchers say they see similar pathways involved in other bad behaviors.&lt;/p&gt;
&lt;p&gt;Gene-Jack Wang, MD, of Brookhaven National Laboratory on New York&apos;s Long Island, has conducted several brain imaging studies of obese patients using PET-CT scans.&lt;/p&gt;
&lt;p&gt;The scans have revealed similarities in brain activity  --  or a lack thereof  --  between patients addicted to cocaine or alcohol, and those &quot;addicted&quot; to eating. Normally, the PET scan lights up when a contrast of radioactive glucose is metabolized, revealing an area of red activity in the center of the brain.&lt;/p&gt;
&lt;p&gt;But in both drug-addicted and obese patients, the scans show very little red activity, because there aren&apos;t enough receptors to which the radioactive glucose can bind. Wang says the decreased availability of dopamine receptors is the brain&apos;s way of coping with a constant dopamine overload.&lt;/p&gt;
&lt;p&gt;&quot;If a person constantly has an excess of dopamine, the brain will down-regulate,&quot; Wang says, explaining the principle commonly referred to as tolerance. &quot;Once the system is down-regulated, we have to do more in order to get the same amount of feeling in our normal state.&quot;&lt;/p&gt;
&lt;p&gt;Thus, obese patients &quot;will want to eat more in order to compensate for their down-regulated system.&quot;&lt;/p&gt;
&lt;p&gt;In other experiments, Wang and his colleagues have also found that a higher body mass index (BMI) correlated with lower prefrontal cortex function  --  the area associated with inhibitory control.&lt;/p&gt;
&lt;p&gt;&quot;If they&apos;re obese,&quot; Wang said, &quot;they have a problem controlling their eating behaviors.&quot;&lt;/p&gt;
&lt;p&gt;Those studies also revealed that a higher BMI was linked to a decrease in memory and executive functioning.&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Out of Control&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Ed Susman was 293 pounds when he decided to join a clinical trial for an investigational weight-loss drug and chronicle his year-long experience for &lt;em&gt;MedPage Today&lt;/em&gt;. (See &lt;a href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; mce_href=&quot;http://www.medpagetoday.com/PrimaryCare/Diabetes/8125&quot; target=&quot;_blank&quot;&gt;Journalist Participant to Present Insider View of Weight-Loss Trial&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Eating, to him, was a &quot;compulsion&quot;  --  as was biting his nails, a habit he picked up at age 4.&lt;/p&gt;
&lt;p&gt;Over the course of the trial, not only did Susman lose 52 pounds, he also stopped his nail-biting.&lt;/p&gt;
&lt;p&gt;He doesn&apos;t yet know if he was in the drug arm of the trial, but he strongly suspects he wasn&apos;t experiencing a placebo effect.&lt;/p&gt;
&lt;p&gt;&quot;I believe I was on the drug because it controlled a compulsion that I had had for 50 years,&quot; Susman says of the nail-biting. &quot;This stopped it cold.&quot;&lt;/p&gt;
&lt;p&gt;Unfortunately, he says, the same didn&apos;t happen with his eating habits, but he&apos;s gained back only 10 of those 52 pounds in the year since his participation in the trial ended.&lt;/p&gt;
&lt;p&gt;The still-investigational drug is lorcaserin  --  a combination of benzazepine and hydrochloride, two neurological agents. Susman says it is &quot;supposed to improve your willpower, your ability to overcome compulsions.&quot;&lt;/p&gt;
&lt;p&gt;Lorcaserin is a selective 5-HT&lt;sub&gt;2C&lt;/sub&gt; receptor agonist, working through the serotonin system, which regulates appetite, mood, and motor behavior.&lt;/p&gt;
&lt;p&gt;Two other investigational obesity drugs target the dopamine reward system  --  Contrave, which is a combination of bupropion and naltrexone, and Qnexa, which combines phentermine and topiramate.&lt;/p&gt;
&lt;p&gt;&quot;Some medications that have used similar dopamine modulation, until now, have failed,&quot; Wang said. &quot;These two companies are using the command of the modulation of the dopamine system with other neurological systems, such as the opiate or norepinephrine system. According to the trials, they&apos;ve been very effective.&quot;&lt;/p&gt;
&lt;p&gt;Wang called the new medications &quot;a bright light for the treatment of obesity.&quot;&lt;/p&gt;
&lt;p&gt;&lt;strong&gt;Kicking the Habit&lt;/strong&gt;&lt;/p&gt;
&lt;p&gt;Basically, the idea of medications that act on the dopamine system is &quot;to cool down those reward pathways,&quot; Levounis says. There are two strategies for doing so: an agonist strategy, or an antagonist strategy.&lt;/p&gt;
&lt;p&gt;The agonist strategy is &quot;feeding the beast, providing activity in the cell so that the cravings go down,&quot; Levounis said. Classic examples are nicotine patches, or methadone for opioid dependence.&lt;/p&gt;
&lt;p&gt;On the other hand, the antagonist strategy is to block the receptors. Naltrexone, for example, will block opioid receptors so that the drug addict won&apos;t feel anything if he or she attempts to get high.&lt;/p&gt;
&lt;p&gt;&quot;After a while, you say, &apos;This is not worth my time, my money, my trouble,&apos; so you stop using,&quot; Levounis explains.&lt;/p&gt;
&lt;p&gt;These have been the two main strategies in addiction pharmacotherapy, but there&apos;s now a &quot;third avenue&quot;  --  the partial agonist approach.&lt;/p&gt;
&lt;p&gt;The partial agonist is one molecule that blocks most receptors while still providing just a little bit of an &quot;oomph&quot; to calm cravings. That&apos;s how varenicline (Chantix) helps smokers quit, and how buprenorphine gets junkies off heroin or other opioids.&lt;/p&gt;
&lt;p&gt;But what about inhibitory control? What if medications could ramp up will power?&lt;/p&gt;
&lt;p&gt;&quot;It&apos;s an area of active research,&quot; Levounis says. &quot;There are some medications proposed, but nothing to write home about.&quot;&lt;/p&gt;
&lt;p&gt;He said treatment is typically twofold. For addicts, psychiatrists will try to &quot;cool down&quot; the reward pathways, often with medication. Then, they target the diminished frontal lobes.&lt;/p&gt;
&lt;p&gt;&quot;We try to beef up the frontal lobes as much as we can, and we do that with psychotherapy,&quot; Levounis said.&lt;/p&gt;
&lt;p&gt;Researchers agree that psychotherapy is key to regaining self-control, and it&apos;s the predominant treatment used in patients with addictive behaviors.&lt;/p&gt;
&lt;p&gt;Mark Smaller, PhD, a psychoanalyst in private practice in Chicago, said psychotherapy often reveals an underlying cause for an addiction or compulsive behavior. Usually, it&apos;s anxiety or depression.&lt;/p&gt;
&lt;p&gt;Acknowledging those problems may help change behaviors. Once they&apos;re realized, a patient can start working against them, with the help of the brain&apos;s own neuroplasticity. Essentially, neurons can disconnect and reconnect, or loosen their connections and tighten them, which often manifests in noticeable change.&lt;/p&gt;
&lt;p&gt;&quot;[Psychological] insights can actually begin to change brain chemistry and diffuse compulsions,&quot; he said. &quot;If you address those issues, you can have a positive impact on your life that can change the chemistry of your brain.&quot;&lt;/p&gt;
&lt;p&gt;Smaller said it &quot;creates a new psychological  --  if not neurological  --  structure that can help regulate behavior.&quot;&lt;/p&gt;
&lt;p&gt;Although research on neuroplasticity is relatively young, the concept of &quot;rewiring&quot; the brain is not new.&lt;/p&gt;
&lt;p&gt;In fact, too often, the electrician metaphor has been employed as an excuse for indulging, an explanation for a New Year&apos;s resolution deferred: &quot;I can&apos;t stop eating chocolate, I&apos;m just not wired that way.&quot;&lt;/p&gt;

                     score="-0.003"

      Whether a clinician calls a mild traumatic brain injury a concussion or not appears to influence how serious the injury is considered to be, researchers found.&lt;br&gt;
&lt;br&gt;Among children admitted for a traumatic brain injury, those who were told they had a concussion were discharged significantly earlier (OR 1.49, 95% CI 1.15 to 1.94) and returned to school sooner (OR 2.42, 95% CI 1.56 to 3.73) than those who were not given the label, Carol DeMatteo, MSc, of McMaster University in Hamilton, Ontario, and colleagues reported in the February issue of &lt;em&gt;Pediatrics&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;The trends remained significant even after adjusting for the severity of the head injury and the presence of other injuries.&lt;/p&gt;
&lt;p&gt;&quot;We suggest that the [concussion] label itself conveys a message and also directs outcomes,&quot; the researchers wrote. &quot;If we want to encourage full reporting with subsequent adequate management and convalescence, perhaps we should use the term &apos;mild traumatic brain injury.&apos;&quot;


 &lt;p&gt;Disagreeing was Kenneth Perrine, PhD, a neuropsychologist at Hackensack University Medical Center in New Jersey.
    &lt;p&gt;&quot;Granted, concussion is by definition a mild brain injury, but it&apos;s so transient that I think it would be a disservice both to the public and for research to continue to confuse mild traumatic brain injury with concussion,&quot; said Perrine, who was not involved in the study.
    &lt;p&gt;He said a true concussion is characterized by feeling like one is in a fog, fatigue, sensitivity to light and sound, headache, blurred vision or other visual disturbances, and feeling off balance.
    &lt;p&gt;A mild traumatic brain injury, on the other hand, has longer-lasting effects and is not usually accompanied by concussion symptoms. Retrograde amnesia, post-traumatic amnesia, and more severe memory loss would occur, he said.
    &lt;p&gt;&quot;They are two distinct entities both from what we call it and from a prognostic standpoint,&quot; said Perrine, who is also consulting neuropsychologist for the New York Jets.
    &lt;p&gt;But, although the term concussion is used widely in clinical records and has garnered much attention in recent years because of head injuries to athletes at all levels of sports, an accepted definition does not exist, according to DeMatteo and her colleagues.&lt;/p&gt;


&lt;p&gt;&quot;Clinicians may use the concussion label because it is less alarming to parents than the term &quot;mild brain injury,&quot; with the intent of implying that the injury is transient with no signi&amp;#64257;cant long-term health consequences,&quot; they said.&lt;/p&gt;

&lt;p&gt;Commenting on the study, Wendy Wright, MD, a neurologist at Emory University in Atlanta, said in an e-mail, &quot;This study puts a spotlight on the issue that concussion is not always taken as seriously as it should be, partly because concussion encompasses a spectrum of disease.&quot;&lt;/p&gt;
&lt;p&gt;She said parents, coaches, teammates, and the individual with the concussion may not believe the injury is serious because symptoms are transient.&lt;/p&gt;
&lt;p&gt;That perception appears to be held by both clinicians and parents alike. DeMatteo and colleagues noted in the journal that during recruitment of the current study, both groups were heard saying, &quot;He doesn&apos;t have a head injury, he has a concussion.&quot;&lt;/p&gt;
&lt;p&gt;However, Wright said, &quot;it must be noted that concussion means brain injury.&quot;&lt;/p&gt;


&lt;p&gt;To explore how the term is used clinically, DeMatteo and colleagues analyzed the records of 434 children admitted to McMaster Children&apos;s Hospital with a diagnosis of acquired brain injury.&lt;/p&gt;
&lt;p&gt;Of those determined to have a traumatic brain injury, 72.7% had a mild injury according to the Glasgow Coma Scale. Nearly one-third (32.4%) were said to have a concussion.&lt;/p&gt;
&lt;p&gt;The concussion label was more likely to be given to children with a mild injury (&lt;em&gt;P&lt;/em&gt;=0.03), but the association was weak, according to the researchers, and nearly one-quarter (24%) of children with moderate or severe scores were also said to have a concussion.&lt;/p&gt;
&lt;p&gt;&quot;This leads one to question the use of the term as being reflective of mild injury and again supports the existence of confusion about what a concussion really is and how the term should best be used in the care of children,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;&quot;Our findings, both in the return-to-school data and the phenomenon we experienced during recruitment, suggest that if a child is given a diagnosis of concussion, then the family is less likely to consider it as a brain injury,&quot; the researchers said.&lt;/p&gt;
&lt;p&gt;They acknowledged some limitations of the study, including the fact that data from medical charts may have had missing information and a lack of control over the validity of measurements and that their use of only a single center might influence the results.&lt;/p&gt;
&lt;p&gt;Further, they wrote, some measures, such as CT frequency, might be inflated because only children who were admitted to the hospital were included in the study. &lt;ul&gt; &lt;/ul&gt;&lt;/p&gt;

The &lt;em&gt;CanChild&lt;/em&gt;&lt;em&gt;&lt;/em&gt; Center for Childhood Disability Research is supported by the Ontario Ministry of Health and Long-Term Care.&lt;/p&gt;&lt;p&gt;The authors reported that they had no relevant financial disclosures to make.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;
