Authors: Buhlmann Ulrike , Wilhelm Sabine , McNally Richard J. , Tuschen-Caffier Brunna , Baer Lee , Jenike Michael A. 
Published: August 2016

ABSTRACTAnxiety-disordered patients and individuals with high trait anxiety tend to interpret ambiguous information as threatening. The purpose of this study was to investigate whether interpretive biases would also occur in body dysmorphic disorder (BDD), which is characterized by a preoccupation with imagined defects in one's appearance. We tested whether BDD participants, compared with obsessive-compulsive disorder participants and healthy controls, would choose threatening interpretations for ambiguous body-related, ambiguous social, and general scenarios. As we hypothesized, BDD participants exhibited a negative interpretive bias for body-related scenarios and for social scenarios, whereas the other groups did not. Moreover, both clinical groups exhibited a negative interpretive bias for general scenarios.

ABSTRACTWhat is the impact of attention-deficit/hyperactivity disorder (ADHD) on the phenotypic expression of pediatric obsessive-compulsive disorder (OCD). We examined phenotypic features, and functional and clinical correlates in youths with OCD, with and without comorbid ADHD, from a large sample of consecutively referred pediatric psychiatry patients. Although comorbid ADHD had no meaningful impact on the phenotypic expression or clinical correlates of OCD, it was associated with higher rates of compromised educational functioning compared with other OCD youths. Our findings suggest that the OCD phenotype runs true and is not impacted by comorbid ADHD in youths diagnosed with both OCD and ADHD. In such affected youths, both disorders contribute to morbid dysfunction and require treatment. More work is needed to determine whether OCD plus ADHD represents a developmentally and etiologically distinct form of the OCD syndrome.
The Comorbidity of Migraine
Authors: Low Nancy C.P. , Merikangas Kathleen Ries 
Published: August 2016

ABSTRACTThis review addresses the methodologic issues relevant to the study of comorbidity and provides a broad overview of the medical and psychiatric conditions associated with migraine. Since the body of literature examining the comorbidity of migraine is enormous, the scope of this review will largely focus on community and case-control studies. Among the selected comorbid medical conditions, including disorders of the cardiovascular, respiratory, neurologic, gastrointestinal and immunologic systems, stroke, asthma, and allergies appear to be most strongly associated with migraine. Among the psychiatric illnesses, mood and anxiety disorders have been shown to be most strongly associated with migraine in the general population. Further research is indicated and necessary to elucidate the precise mechanism of migraine comorbidity.

Published: August 2016

ABSTRACTBackground:Personality traits have been hypothesized to involve specific neurotransmitter systems. In order to test this model, the relationship between the responses to serotonergic and noradrenergic probes, central cerebrospinal fluid (CSF) measures of monoamine neurotransmitters and the Tridimensional Personality Questionnaire (TPQ) were evaluated in a cohort of personality disorder subjects.Methods:A total of 142 patients meeting at least one personality disorder (meeting Diagnostic and Statistical Manual of Mental Disorders, Third Edition–Revised criteria) participated in these studies. The prolactin response to fenfluramine (a measure of serotonin function) was obtained for 110 subjects; growth hormone response to clonidine (a measure of noradrenergic function) was obtained for 77 subjects, while homovanillic acid (HVA) at baseline, an index of dopaminergic function, was available for 103 subjects. Measures of central neurotransmitter function (dopaminergic, serotonergic, and noradrenergic: HVA, 5-hydroxyindolacetic acid, and 3-methoxy-4-hydroxyphenylglycol, respectively) were available for 36 subjects. Separate regression analyses utilizing each of the hypothesized associations, where the TPQ total scores were used as the dependent measures and the biologic indices were the independent measures were conducted. Exploratory correlational analyses between these biologic measures and the four dimensions of the TPQ (and its subscales) were also conducted. (Correlations are reported if they would remain significant at P<.01 level after Bonferroni correction for multiple comparisons across the six neuroendocrine measures).Results:In the regression analyses, there was a trend association between CSF and plasma HVA in predicting novelty-seeking (P<.07). No other significant associations were found in the other three measures. Regarding the individual correlational analyses, the persistence scale of the TPQ was significantly positively correlated with the growth hormone response to clonidine (r=.30, P<.008). The sentimentality subscale (reward dependence) was positively correlated with CSF 5-hydroxyindolacetic acid (r=0.45, P<.001), while the attachment subscale (also reward dependence) was correlated with CSF 3-methoxy-4-hydroxyphenylglycol (r=0.49, P<.002).Conclusion:Limited support was provided for a relationship between monoamines, particularly dopamine and novelty-seeking as well as norepinephrine and reward dependence but other hypothesized relationships were not supported by these measures.
Update on the Biology of Seasonal Affective Disorder
Authors: Sohn Chang-Ho , Lam Raymond W. 
Published: August 2016

AbstractThe etiology and pathophysiology of seasonal affective disorder (SAD) has been linked to the seasons and to light since its first conceptualization. Aspects of SAD that make it particularly amenable to biological investigation include the predictable recurrent episodes, the rapid response to a nonpharmacologic treatment, the specific neurovegetative features, and the availability of rich animal models of seasonality. This paper reviews new findings for the major biological hypotheses for SAD, focusing on circadian rhythms, neurotransmitters, and molecular genetics. Integrative issues and future directions for the study of SAD, including the heuristic value of a dualvulnerability hypothesis that conceptualizes seasonality as a dimensional construct and the importance of studying endophenotypes, will be discussed.

Published: August 2016

ABSTRACTSystematic investigations indicate that some of the recognized psychiatric disorders can be identified among those with mental retardation due to chromosomal abnormalities. We report a psychotic patient with mild mental retardation (intelligence quotient: 68) and minor anomalies that had a chromosomal aberration not previously described in a psychotic patient. Our patient highlights the importance of the cytogenetic study in psychiatric patients with comorbid mental retardation or minor anomalies. In addition, her psychosis symptoms may be helpful to propose a new candidate gene for psychosis.
Cognitive-Behavioral Treatment of Irritable Bowel Syndrome
Authors: Toner Brenda B. 
Published: August 2016

ABSTRACTThere is increasing evidence that supports the view that irritable bowel disorder (IBS) is a disorder of brain-gut function. Cognitive-behavioral therapy (CBT) has received increased attention in light of this recent shift in the conceptualization of IBS. This review has two main aims. The first is to provide a critical review of controlled trials on CBT for IBS. The second is to discuss ways of further developing CBT interventions that are more clinically relevant and meaningful to health care providers and individuals with a diagnosis of IBS. A theme from a CBT intervention will be presented to illustrate how CBT interventions can be incorporated within a larger social context. A review of CBT for IBS lends some limited support for improvement in some IBS symptoms and associated psychosocial distress. This conclusion needs to be expressed with some caution, however, in light of many methodological shortcomings including small sample sizes, inadequate control conditions and failure to identify primary versus secondary outcome measures. In addition, future studies will need to further develop more relevant CBT protocols that more fully integrate the patient's perspective and challenge social cognitions about this stigmatized disorder.
Increased Prevalence of Functional Gastrointestinal Disorders in Panic Disorder: Clinical and Theoretical Implications
Authors: Lydiard R. Bruce 
Published: August 2016

ABSTRACTBackground:Functional gastrointestinal disorders (FGID) are a group of disorders characterized by recurrent gastrointestinal distress for which no structural or biochemical cause can be discerned. Irritable bowel syndrome (IBS) is an FGID estimated to affect 10% to 25% of the United States population. IBS occurs in over 40% of individuals with panic disorder, and in patients with IBS, 25% to 30% have panic disorder, which has led to speculation about possible shared pathophysiology between the two. Less is known about the prevalence of other FGID in individuals with panic disorder.Objective:The purpose of this study was to examine the prevalence of IBS and all the other FGID in patients with current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) panic disorder.Introduction:We assessed FGIDs in 73 treatment-seeking DSM-IV panic disorder patients via the Diagnostic Interview Questions for Functional Gastrointestinal Disorders and made descriptive comparisons with a large convenience sample from an already-completed United States Household Survey (USHS), which employed the same diagnostic criteria.Results:The prevalence of IBS and other FGIDs in both men and women with panic disorder were substantially higher than in the USHS respondents. Women with panic disorder had significantly more functional chest pain than men, but there was no gender difference in IBS. With the exception of functional anorectal and biliary disorders, the FGID prevalences were comparatively higher in panic disorder versus the USHS respondents.Discussion:This survey supports earlier reports of a high prevalence of IBS in individuals with panic disorder and also suggests that the prevalence of several other FGIDs were comparatively high as well. Methodological limitations precluded direct statistical analysis. It may be that commonly overlapping psychiatric and often-painful FGIDs, and extra-intestinal disorders increase the risk for comorbidity in already-affected individuals via shared pathophysiology. One potential model for which there is some evidence for a role in stress, panic disorder, FGIDs and several extra-intestinal functional conditions is dysregulation of corticotropin-releasing factor function.Conclusion:The prevalence of FGIDs in DSM-IV panic disorder was comparatively higher than in USHS respondent community sample, which used similar FGID diagnostic criteria. The cause for the apparent close association of panic disorder with FGID may represent shared pathophysiology. Increased understanding of the mechanism of the overlap may allow for improved treatment of the significant proportion of the population suffering from comorbid psychiatric and functional medical conditions.
Bipolar Disorder:Emotional Dysregulation and Neuronal Vulnerability
Authors: Stein Dan J. , Horn Neil , Ramesar Rajkumar , Savitz Jonathan 
Published: August 2016

ABSTRACTBipolar disorder is clinically characterized by fluctuating affect, and neuropsychologically by impairment in executive functions. Such phenomena are consistent with the centrality of emotional dysregulation and impulsivity to bipolar disorder. They are also consistent with a key role for prefrontal-subcortical (striatal-thalamic) and associated limbic circuitry in its mediation. Furthermore, there is growing data on the cellular mechanisms contributing to neuronal vulnerability in this mediating circuitry.

Published: August 2016

ABSTRACTThe cause of anorexia nervosa (AN) is unclear, but is likely multifactorial, including psychological, familial, environmental, societal, genetic, and other biological factors. This case report of identical 12-year-old female triplets simultaneously concordant for AN illustrates the importance of addressing all these components in evaluation and treatment, and the difficulty of determining the relative importance of each factor in the cause of an individual's eating disorder. An overly close relationship and competitiveness between the girls, treated at times as a triplet group rather than as individuals, as well as stressful family dynamics, were probably important antecedents to the girls' AN. The girls encouraged each other and competed to lose weight. Brief individual and family psychotherapy, parent counseling, nutritional counseling, and psychoeducation led to successful treatment. The triplets were encouraged in treatment to compete with and encourage each other to obtain treatment goals, including eating more healthily and achieving healthy weights. A literature review of AN twins studies is also presented, as these studies add to our understanding of the relative importance of shared genes and shared environment in the development of AN. These studies also add insight into treating individuals from families with multiple affected relatives.

Published: August 2016

ABSTRACTIntroduction:High frequency repetitive transcranial magnetic stimulation (HF-rTMS) of the left dorsolateral prefrontal cortex (DLPFC) might be a promising strategy to treat depression, but not all patients show a positive outcome.Objective:In this open study, we evaluate whether a favorable HF-rTMS treatment outcome could be predicted by baseline prefrontal brain glucose metabolism (CMRglc), measured by18fluorodeoxyglucose positron emission tomography (18FDG-PET).Methods:A sample of 21 antidepressant-free, treatment-resistant depression (TRD) patients of the melancholic subtype received 10 sessions of HF-rTMS delivered on the left DLPFC. Patients underwent a static18FDG-PET before and after HF-rTMS treatment.Results:Forty-three percent of the patients showed a reduction of at least 50% on their Hamilton Rating Scale for Depression scores. Higher baseline metabolic activities in the DLPFC and the anterior cingulate cortex (ACC) were associated with better clinical outcome. Successful HF-rTMS treatment was related to metabolic changes in subdivisions of the ACC (Brodmann areas 24 and 32).Conclusion:This biological impact of HF-rTMS on regional brain CMRglc explains to some extent how HF-rTMS may improve moods in TRD patients. Larger sham-controlled HF-rTMS treatment studies are needed to confirm these results.
Functional Magnetic Resonance Imaging Studies in Bipolar Disorder
Authors: Yurgelun-Todd Deborah A. , Ross Amy J. 
Published: August 2016

ABSTRACTAbnormalities in brain activation using functional magnetic resonance imaging (fMRI) during cognitive and emotional tasks have been identified in bipolar disorder patients, in frontal, subcortical and limbic regions. Several studies also indicate that mood state may be differentiated by lateralization of brain activation in fronto-limbic regions. The interpretation of fMRI studies in bipolar disorder is limited by the choice of regions of interest, medication effects, comorbidity, and task performance. These studies suggest that there is a complex alteration in regions important for neural networks underlying cognition and emotional processing in bipolar disorder. However, measuring changes in specific brain regions does not identify how these neural networks are affected. New analytical techniques of fMRI data are needed in order to resolve some of these issues and identify how changes in neural networks relate to cognitive and emotional processing in bipolar disorder.
Retrospective Case Review of Lamotrigine Use for Affective Instability of Borderline Personality Disorder
Authors: Weinstein Wendy , Jamison Katrina L. 
Published: August 2016

ABSTRACTIntroduction: The diagnosis of borderline personality disorder is complex as is its pharmacologic treatment. Lamotrigine may offer promise in the treatment of this condition.Objective: To assess the use of lamotrigine to treat symptoms of affective instability in patients with borderline personality disorder.Methods: Charts of patients treated with lamotrigine in a private practice during the period of 2003–2004 were reviewed. Patients were included in the analysis if they had been given a clinical diagnosis of borderline personality disorder as defined in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-Text Revision, had continued to display affective instability while taking their previous medications before being treated with lamotrigine; had received a Clinical Global Impression-Severity score before and after lamotrigine therapy; had been treated with lamotrigine, as monotherapy or adjunctive therapy, at a dose ranging from 50–200 mg/day; and continued to take lamotrigine for at least 3 months.Results: The charts of 13 patients were reviewed and included in the analysis. All patients were female, 19–43 years of age, and had reported continuing symptoms of affective instability despite treatment with two to seven psychotropic drugs, including, but not limited to, fluoxetine, paroxetine, escitalopram, buproprion, and clonazepan. The duration of lamotrigine treatment, before the end of the period covered by the chart review was 3–15 months. The patients had initial Clinical Global Impression-Severity scores of 5 or 6 and a final scores of 1 or 2, except for one patient with an initial score of 3 and a final score of 1 and one patient with an initial score of 6 and a final score of 7.Conclusion: Lamotrigine seems to be a safe and effective option for the treatment of patients with symptoms of affective instability associated with borderline personality disorder.
Modulation of Fear and Anxiety by the Endogenous Cannabinoid System
Authors: Chhatwal Jasmeer P. , Ressler Kerry J. 
Published: August 2016

ABSTRACTThe last decade has witnessed remarkable progress in the understanding of the mammalian cannabinoid system, from the cloning of the endogenous cannabinoid receptor to the discovery of new pharmacologic compounds acting on this receptor. Current and planned studies in humans include compounds with effects ranging from direct antagonists to inhibitors of reuptake and breakdown. This progress has been accompanied by a much greater understanding of the role of the cannabinoid system in modulating the neural circuitry that mediates anxiety and fear responses. This review focuses on the neural circuitry and pharmacology of the cannabinoid system as it relates to the acquisition, expression, and extinction of conditioned fear as a model of human anxiety. Preclinical studies suggest that these may provide important emerging targets for new treatments of anxiety disorders.
Serotonin Syndrome Associated with the Use of Escitalopram

Published: August 2016

ABSTRACTEscitalopram is the newest selective serotonin reuptake inhibitor (SSRI) available for use in the United States. It has been approved for the treatment of major depression and generalized anxiety disorder. It is the S-enantiomer of the SSRI citalopram and is highly serotonin specific as it has minimal effect on the reuptake of dopamine or norepinephrine. It is also a well-tolerated medication, with a side-effect profile comparable to the other SSRIs. While a number of side effects have been seen during escitalopram therapy, such as insomnia, nausea, and increased sweating, there are no reported cases of serotonin syndrome associated with escitalopram therapy to date. We present the case of a 24-year-old woman who developed serotonin syndrome after an increase in her escitalopram to 30 mg/day. We will review the diagnostic criteria of serotonin syndrome and the clinical scenarios in which serotonin syndrome can develop. We will also discuss the proposed treatments and role that polypharmacology may play in the development of this clinical entity.
Suicidal Ideation Versus Suicidal Obsession: A Case Report
Authors: Wetzler Alzbeta Juven , Elias Rachela , Fostick Leah , Zohar Joseph 
Published: August 2016

ABSTRACTThis case report illustrates the relationship between stress and obsessive-compulsive disorder (OCD) by describing an unusual case of OCD sequelae following a suicide attempt. The patient is a 29-year-old married woman who suffered a major depressive episode without OCD and tried to commit suicide by drinking household cleaner. Following the attempt, violent obsessive thoughts of harming herself and others emerged along with avoidance behavior. After exposure therapy, there was a decrease in her obsessive thoughts, less anxiety, and no avoidance behavior. This report highlights not only the existence of “posttraumatic obsession” but also the importance of accurate interpretation of suicidal preoccupation, leading to the diagnosis of OCD rather then suicidal ideation secondary to depression.
Rasmussen's Syndrome: Intractable Epilepsy and Progressive Neurological Deterioration From a Unilateral Central Nervous System Disease
Authors: Carney Paul R. 
Published: August 2016

AbstractRasmussen's syndrome (chronic encephalitis with epilepsy) is a rare neurological disorder of unknown cause characterized by severe epilepsy, hemiplegia, dementia, and inflammation of the brain, and progressive functional and structural destruction of a single cerebral hemisphere. While one mechanism underlying the pathogenesis of Rasmussens encephalitis has been hypothesized to be mediated by production of excitotoxic GluR3 autoantibodies to the a-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) receptor, other neuropathological etiologies have also been indicated. Proposed therapies have included antiepileptics, steroids, antiviral agents, alpha-interferon, and immunoglobulin. The mainstay of therapy is surgical hemispherectomy. To date, no medical therapies have permanently halted neurologic deterioration.
