      Patients with body dysmorphic disorder have abnormal brain activity when viewing their own faces, researchers say.&lt;br&gt;
&lt;br&gt;Brain imaging scans revealed hypoactivity in visual processing regions and hyperactivity in frontostriatal systems when patients with the disease looked at an image of their own face, Jamie D. Feusner, MD, of UCLA, and colleagues reported in the February &lt;em&gt;Archives of General Psychiatry.&lt;/em&gt;&lt;br&gt;
&lt;br&gt;&quot;Abnormalities in visual processing systems may contribute distorted perceptual input to frontostriatial systems, which may be associated with the experience of aversion, and that may subsequently mediate obsessive thought patterns and urges to perform compulsive behaviors,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;Patients with body dysmorphic disorder are preoccupied with perceived defects in their appearance  --  particularly in their faces.&lt;/p&gt;
&lt;p&gt;Little is known about the pathophysiology of the disease. One school calls it an obsessive-compulsive spectrum disorder, but there&apos;s also evidence it may be related to social phobia, eating disorders, or delusional disorder.&lt;/p&gt;
&lt;p&gt;Early research has shown evidence of abnormal visual processing, and a better understanding of the neurobiology of the disease may shed light on how to better categorize it, the researchers said.&lt;/p&gt;
&lt;p&gt;So to determine whether body dysmorphic disorder patients have abnormal patterns of brain activation when visually processing their own face, the researchers conducted a case-control study using functional Magnetic Resonance Imaging (fMRI) at a university hospital among 17 patients and 16 matched controls.&lt;/p&gt;
&lt;p&gt;All participants viewed three different types of face images for two different faces: their own and a control face. The images were either an unaltered neutral-expression photograph, an image altered to include only high spatial frequency, or one altered to include only low spatial frequency.&lt;/p&gt;
&lt;p&gt;The researchers found that patients with body dysmorphic disorder had hypoactivity in primary and secondary visual processing regions when they viewed facial images with low spatial frequency.&lt;/p&gt;
&lt;p&gt;This suggests aberrant processing of configural and holistic information, which the low-spatial-frequency images convey, they noted, and may indicate a relative deficit of dorsal-stream magnocellular pathway activity, which normally provides a low-resolution template of the visual image.&lt;/p&gt;
&lt;p&gt;&quot;Clinically, this may account for the impaired ability to perceive the visual gestalt, contributing to distorted perceptions of the individuals&apos; appearance when viewing their face,&quot; the researchers wrote.&lt;/p&gt;
&lt;p&gt;They also found hyperactivity in the left orbitofrontal cortex and bilateral head of the caudate when patients viewed their own face unaltered.&lt;/p&gt;
&lt;p&gt;These frontostriatial systems mediate inhibitory control and flexibility in response, and guide behavior based on action-outcome associations, the researchers noted. Studies have shown this area to be hyperactive in obsessive-compulsive disorders.&lt;/p&gt;
&lt;p&gt;The results are &quot;preliminary evidence of a possible similarity in functional neuroanatomy between body dysmorphic disorder and obsessive-compulsive disorder,&quot; they wrote, cautioning that future studies directly comparing brain pathophysiology between the two disorders are necessary.&lt;/p&gt;
&lt;p&gt;Finally, mean aversiveness ratings across all own-face stimuli were higher in body dysmorphic disorder patients than in controls (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001). Frontostriatal hyperactivity may be associated both with aversion and with symptoms of obsessive thoughts and compulsive behaviors, the researchers added.&lt;/p&gt;
&lt;p&gt;Researchers noted that the study was limited by small sample size and small effect sizes.&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;

                     title="Handedness Linked to ADHD (CME/CE)"
                     score="0.004"
                     href="http://www.medpagetoday.com/Psychiatry/GeneralPsychiatry/tb/18113?impressionId=1265759610757"
                     
      &lt;p&gt;Ambidextrous 5-year-olds are more likely to develop attention deficit-hyperactivity disorder symptoms later on as compared with right- and left-handed children, according to a study by a team of Swedish researchers.&lt;/p&gt;
&lt;p&gt;The findings are an indication that brain morphology and neural circuitry associated with handedness also affects cognitive and behavioral function, according to Alina Rodriguez, PhD, of Uppsala University in Sweden, and colleagues in an online report in &lt;em&gt;Pediatrics&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;The conclusions emerged from a longitudinal study of 7,871 children in northern Finland born in 1986, of whom 87 were mixed-handed, 632 showed a left-hand preference, and the remainder were right-handed at age 5.&lt;/p&gt;
&lt;p&gt;Rodriguez and colleagues found that when these children were tested at age 8, teachers were about twice as likely to report hyperactivity (odds ratio 2.06, 95% CI 1.09 to 3.91) or a combination of inattention and hyperactivity (OR 2.16, 95% CI 1.21 to 3.86) in the mixed-handed children compared with the right-handed ones.&lt;/p&gt;
&lt;p&gt;Similar increases in rates of teacher assessments of probable psychiatric disturbance and in overall school performance, as well as in parental reports of language problems, were seen in the ambidextrous children.&lt;/p&gt;
&lt;p&gt;Moreover, these learning and behavioral problems persisted into adolescence.&lt;/p&gt;
&lt;p&gt;Cohort members were evaluated at age 16 by parents on ADHD symptoms and provided self-reports of language and math performance in school.&lt;/p&gt;
&lt;p&gt;Those classed as mixed-handed were more than three times as likely to suffer inattention (OR 3.53, 95% CI 1.65 to 7.53) or a combination of inattention and hyperactivity-impulsivity (OR 3.16, 95% CI 1.42 to 7.08) relative to right-handed 16-year-olds, according to their parents.&lt;/p&gt;
&lt;p&gt;Self-reported problems in Finnish language and math classes were also significantly more common in the mixed-handed youths (OR 1.85, 95% CI 1.00 to 3.43 for language; OR 2.55, 95% CI 1.48 to 4.37 for math).&lt;/p&gt;
&lt;p&gt;These effects were not seen in left-handed children, Rodriguez and colleagues reported.&lt;/p&gt;
&lt;p&gt;&quot;Mixed-handedness can be used as a marker of risk for difficulties and warrants additional evaluation,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;Adjusting for gender and birth weight and gestational age reduced the strength of the association between mixed-handedness and behavioral and learning problems. The point estimates of odds ratios for inattention and/or hyperactivity declined 1.4 to 1.6 and statistical significance was lost.&lt;/p&gt;
&lt;p&gt;But that actually supports the hypothesis that brain abnormalities stemming from before birth underlie what they called &quot;atypical lateralization&quot; and subsequent learning and behavior problems, Rodriguez and colleagues indicated.&lt;/p&gt;
&lt;p&gt;&quot;Recent neuropsychological work related to patterns of brain organization and function corroborates our findings,&quot; they added.&lt;/p&gt;
&lt;p&gt;They cited research indicating that ADHD is associated with left-side motor deficits, apart from hand preference, as well as reduced attention to visual stimuli on the left versus right side. These observations suggest weaker right hemisphere function, Rodriguez and colleagues argued.&lt;/p&gt;
&lt;p&gt;Other studies have suggested that neural transmission can be asymmetric between hemispheres, they said.&lt;/p&gt;
&lt;p&gt;&quot;These studies together highlight the possible interconnection among mixed-handedness, neurotransmitter dysfunction in the right hemisphere, and ADHD symptoms,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;The authors pointed out that the &quot;impreciseness of handedness as a proxy for atypical lateralization is a limitation.&quot; Yet, the cost of direct assessment of the brain by imaging or electrical activity is &quot;prohibitive&quot; so handedness was a &quot;feasible alternative for large epidemiologic studies.&quot;&lt;/p&gt;
&lt;p&gt;And they said that even though the number of prevalence of mixed-handedness was low, &quot;it seems unlikely that those with right- or left-handedness were misclassified as mixed.&quot;&lt;/p&gt;

Rodriguez also was supported by VINNMER.&lt;/p&gt;&lt;p&gt;No potential conflicts of interest were reported.&lt;/p&gt;&lt;/div&gt;&lt;div style=&quot;clear:both;&quot;&gt;&lt;/div&gt;

                     score="-0.004"
                     href="http://www.medpagetoday.com/MeetingCoverage/SCCM/tb/17973?impressionId=1265759610757"
                     
      &lt;p&gt;MIAMI BEACH  --  Elderly patients sedated with morphine or haloperidol (Haldol) in surgical intensive care units were less likely to to be discharged to their homes and more likely to be discharged to a nursing facility than patients given other sedatives, often resulting in a poorer quality of life, researchers reported here.&lt;/p&gt;
&lt;p&gt;Patients who received morphine were 2.57 times more likely to be discharged to a nursing home, rehabilitation center, or a skilled nursing facility (&lt;em&gt;P&lt;/em&gt;=0.029), Carrie Miller, MS, CRNP of the Hospital of the University of Pennsylvania in Philadelphia, told attendees at the annual meeting of the Society of Critical Care Medicine.&lt;/p&gt;
&lt;p&gt;Patients who were given haloperidol were 12.46 times more likely to be discharged to one of those facilities rather than to their home.&lt;/p&gt;
&lt;p&gt;Similarly, the risk of having a significantly reduced function from baseline admission was five times greater if the patient had received haloperidol (&lt;em&gt;P&lt;/em&gt;=0.044) and 2.76 times more likely if the patient had received morphine (&lt;em&gt;P&lt;/em&gt;=0.011), Miller said.&lt;/p&gt;
&lt;p&gt;&quot;While older adults frequently require medications to treat pain, anxiety, and delirium, little is know about the effects these medication have on older adults&apos; functional ability or quality of life,&quot; Miller said.&lt;/p&gt;
&lt;p&gt;To shed some light on the question, she and her colleagues evaluated 114 patients in three surgical ICUs. Mean age was about 75, some 60% were men, and 85% were white. Overall, 37% were undergoing general surgical procedures, while 35% had undergone vascular procedures and 16% were trauma patients.&lt;/p&gt;
&lt;p&gt;Patients&apos; level of consciousness and delirium status were assessed daily and information about medication use was gleaned from the ICU flow sheet and the computerized administration record.&lt;/p&gt;
&lt;p&gt;The most frequently used narcotic in the surgical ICU was fentanyl (Duragesic), administered to 77 patients; the most frequently used sedative was midazolam (Versed); and the most frequently used antipsychotic was haloperidol.&lt;/p&gt;
&lt;p&gt;Miller and her colleagues noted that use of propofol (Diprivan) appeared to be associated with better outcomes as far as discharge to one&apos;s home was concerned.&lt;/p&gt;
&lt;p&gt;They noted that there was &quot;considerable discrepancy&quot; between medication usage and dosage recorded on the patients&apos; flow sheet and medication administration record. &quot;Researchers and clinicians should consider that administered prn medications may not always be recorded on the nursing flow sheet,&quot; they concluded.&lt;/p&gt;
&lt;p&gt;The study did not control for confounding variables such as the severity of illness or comorbidities that may have affected outcomes, Miller said.&lt;/p&gt;
&lt;p&gt;&quot;This is an interesting study,&quot; said Suzan Streichenwein, MD, a private practice geriatric psychiatrist in West Palm Beach, Fla. &quot;It would be valuable for future studies to include the severity of illness or more specific details about the type of surgery relative to the dosages of morphine used and its influence on the discharge functional outcomes.&lt;/p&gt;
&lt;p&gt;&quot;Tests diagnosing mild cognitive impairment and/or dementia preop versus postop as well as the time period under anesthesia in relation to outcomes would also be helpful,&quot; said Streichenwein, who was not involved in the study.&lt;/p&gt;
&lt;p&gt;Streichenwein told &lt;em&gt;MedPage Today&lt;/em&gt; that other possible confounding factors require further studies in this area.&lt;/p&gt;
