Abstract
OBJECTIVE Binge eating disorder (BED), although relatively recently recognized as a distinct clinical syndrome, is the most common eating disorder. BED can occur as a separate phenomenon or in combination with other mental disorders, adding to the overall burden of the illness. Due to the relatively short history of recognizing BED as a distinct disorder, this review aimed to summarize the current knowledge on the co-occurrence of BED with other psychiatric disorders. METHOD This review adhered to the PRISMA guidelines. Multiple databases, such as MEDLINE, MEDLINE Complete, and Academic Search Ultimate, were used to identify relevant studies. Of the 3766 articles initially identified, 63 articles published within the last 13 years were included in this review. This systematic review has been registered through INPLASY (INPLASY202370075). RESULTS The most frequently observed comorbidities associated with BED were mood disorders, anxiety disorders and substance use disorders. They were also related to more severe BED presentations. Other psychiatric conditions frequently associated with BED include reaction to severe stress and adjustment disorders, impulse control disorder, ADHD, personality disorders, behavioral disorders, disorders of bodily distress or bodily experience, and psychotic disorders. Additionally, BED was linked to suicidality and sleep disorders. DISCUSSION The findings highlight the interconnected nature of BED with various psychiatric conditions and related factors, shedding light on the complexity and broader impact of BED on mental health and the need for appropriate screening and appropriately targeted clinical interventions.

Abstract
Estimated rates of co-occurrence between obsessive and compulsive disorder (OCD) and panic disorder (PD) are notable, but vary considerably, with rates from epidemiological and clinical studies ranging from 1.8% to 22% (Rector et al., 2017). We reviewed the current empirical literature on the etiology, treatment, diagnostic assessment, and differential diagnosis of co-occurring OCD/PD. Best practices for cognitive-behavioral treatment, including identifying and addressing treatment barriers are also addressed. Although it is acknowledged in current literature that co-occurring OCD and PD levels may be clinically significant, there remains a need to thoroughly examine the possible consequences and future research directions of this overlap. Future research must continue to elucidate the biological and environmental causes of OCD/PD co-occurrence.

The relationship between obsessive-compulsive disorder and anxiety disorders: A question of diagnostic boundaries or simply severity of symptoms? Compr Psychiatry 2019; 94:152116.

Abstract
BACKGROUND A growing number of studies are questioning the validity of current DSM diagnoses, either as "discrete" or distinct mental disorders and/or as phenotypically homogeneous syndromes. In this study, we investigated how symptom domains in patients with a main diagnosis of obsessive-compulsive disorder (OCD), panic disorder (PD) and social anxiety disorder (SAD) coaggregate. We predicted that symptom domains would be unrelated to DSM diagnostic categories and less likely to cluster with each other as severity increases. METHODS One-hundred eight treatment seeking patients with a main diagnosis of OCD, SAD or PD were assessed with the Dimensional Obsessive-Compulsive Scale (DOCS), the Social Phobia Inventory (SPIN), the Panic and Agoraphobia Scale (PAS), the Anxiety Sensitivity Index-Revised (ASI-R), and the Beck Depression and Anxiety Inventories (BDI and BAI, respectively). Subscores generated by each scale (herein termed "symptom domains") were used to categorize individuals into mild, moderate and severe subgroups through K-means clusterization and subsequently analysed by means of multiple correspondence analysis. RESULTS Broadly, we observed that symptom domains of OCD, SAD or PD tend to cluster on the basis of their severities rather than their DSM diagnostic labels. In particular, symptom domains and disorders were grouped into (1) a single mild "neurotic" syndrome characterized by multiple, closely related and co-occurring mild symptom domains; (2) two moderate (complicated and uncomplicated) "neurotic" syndromes (the former associated with panic disorder); and (3) severe but dispersed "neurotic" symptom domains. CONCLUSION Our findings suggest that symptoms domains of treatment seeking patients with OCD and anxiety disorders tend to be better conceptualized in terms of severity rather than rigid diagnostic boundaries.

Abstract
Compulsive behavior is observed in several neuropsychiatric disorders such as obsessive-compulsive disorder (OCD), anxiety, depression, phobia, and schizophrenia. Thus, compulsivity has been proposed as a transdiagnostic symptom with a highly variable pharmacological treatment. Recent evidence shows that glutamate pharmacotherapy may be of benefit in impaired inhibitory control. The purpose of the present study was: first, to test the comorbidity between compulsivity and other neuropsychiatric symptoms on different preclinical behavioral models; second, to assess the therapeutic potential of different glutamate modulators in a preclinical model of compulsivity. Long Evans rats were selected as either high (HD) or low (LD) drinkers corresponding with their water intake in schedule-induced polydipsia (SIP). We assessed compulsivity in LD and HD rats by marble burying test (MBT), depression by forced swimming test (FST), anxiety by elevated plus maze (EPM) and fear behavior by fear conditioning (FC) test. After that, we measured the effects of acute administration (i.p.) of glutamatergic drugs: N-Acetylcysteine (NAC; 25, 50, 100 and 200 mg/kg), memantine (3.1 and 6.2 mg/kg) and lamotrigine (15 and 30 mg/kg) on compulsive drinking on SIP. The results obtained showed a relation between high compulsive drinking on SIP and a higher number of marbles partially buried in MBT, as well as a higher percentage of freezing on the retrieval day of FC test. We did not detect any significant differences between LD and HD rats in FST, nor in EPM. The psychopharmacological study of glutamatergic drugs revealed that memantine and lamotrigine, at all doses tested, decreased compulsive water consumption in HD rats compared to LD rats on SIP. NAC did not produce any significant effect on SIP. These results indicate that the symptom clusters of different forms of compulsivity and phobia might be found in the compulsive phenotype of HD rats selected by SIP. The effects of memantine and lamotrigine in HD rats point towards a dysregulation in the glutamatergic signaling as a possible underlying mechanism in the vulnerability to compulsive behavior on SIP. Further studies on SIP, could help to elucidate the therapeutic role of glutamatergic drugs as a pharmacological strategy on compulsive spectrum disorders.

Abstract
Obsessive-compulsive disorder (OCD) is phenotypically heterogeneous. Gender is an important factor mediating this heterogeneity. We examined gender differences in a large sample (n = 945) of OCD patients under a multi-centric study in India. Cross-sectional assessments were done on consecutive adult (>18 years) treatment-seeking patients with a DSM-5 diagnosis of OCD. Subjects were assessed on Structured Clinical Interview for DSM-5-Research Version for comorbid psychiatric illnesses, Yale Brown Obsessive Compulsive Scale for OCD phenomenology and symptom severity, Brown Assessment of Beliefs Scale for insight, Beck's Depression Inventory for severity of depressive symptoms, and the Obsessive Beliefs Questionnaire. On multivariate backward Wald logistic regression analysis, males (59.7%) had more years of education, had a higher rate of checking compulsions and comorbid substance use disorders. Women were more likely to be married, more commonly reported precipitating factors, had a higher rate of hoarding compulsions and comorbid agoraphobia. Findings from this large study validate gender as an important mediator of phenotypic heterogeneity in OCD. The mechanistic basis for these differences might involve complex interactions between biological, cultural and environmental factors.

Abstract
Objective: We investigated the diagnostic efficiency and clinical utility of the Dimensional Obsessive-Compulsive Scale (DOCS) and subscales for distinguishing obsessive-compulsive disorder (OCD) from anxiety disorders (ADs). Method: A total of 369 participants (167 male, Mage = 29.61 years) diagnosed with DSM-IV OCD or AD, recruited from specialty clinics across the United States, completed clinical interviews and self-report questionnaires, including the DOCS. Receiver operating characteristic analyses and diagnostic likelihood ratios (DiLRs) determined discriminative validity and provided clinical utility. Logistic regressions tested for incremental validity in the DOCS-total scale and subscales in predicting OCD status. Results: The DOCS-total scale and Contamination subscale performed best in differentiating between OCD and AD diagnosis (DOCS-total: Area under curve [AUC] = .75, p < .001; Contamination: AUC = .70, p < .001) as compared with the other subscales. At high scores (DOCS-total: 28+, Contamination: 6+), Contamination was more effective than the DOCS-total in differentiating OCD from ADs, with high scores in Contamination quadrupling OCD odds and DOCS-total by about threefold (Contamination DiLR+ = 4.04, DOCS-total DiLR+ = 2.82). At low scores (DOCS-total: 0-9, Contamination: 0-2), the converse was true, with low scores in Contamination cutting OCD odds by half and DOCS-total by one fifths (Contamination DiLR- = 0.52, DOCS-total DiLR- = 0.23). Conclusion: At high scores, the Contamination subscale is the most helpful subscale to differentiate OCD and ADs. For low scores, the DOCS-total scale performs the best among the scales.

Abstract
RATIONALE Clinical studies have shown that some psychoactive recreational drugs have therapeutic applications in anxiety, depression, and schizophrenia. However, to date, there are few studies on the therapeutic potential efficacy of recreational drugs in compulsive neuropsychiatric disorders. OBJECTIVES We explored the therapeutic potential of different psychoactive and psychedelic drugs in a preclinical model of compulsive behavior. METHODS Outbred male Wistar rats were selected as either high (HD) or low (LD) drinkers according to their behavior in schedule-induced polydipsia (SIP). Subsequently, we assessed the effects of acute administration of scopolamine (0.125, 0.25, and 0.5 mg/kg), methamphetamine (0.25, 0.5, 1.25, and 2.5 mg/kg), ketamine (1.25, 2.5, 5, and 10 mg/kg), cannabidiol (1 and 3 mg/kg), WIN21255-2 (0.5, 075, and 1 mg/kg), and AM404 (0.25 and 0.5 mg/kg) on compulsive drinking in SIP. RESULTS Scopolamine reduced dose-dependent compulsive drinking in HD compared with LD rats in SIP. Methamphetamine induced a dose-dependent inverted U-curve effect in both groups, in which lower doses increased and higher doses reduced compulsive drinking in SIP. Ketamine, cannabidiol, WIN21255-2, and AM404 did not have any relevant effects in SIP. CONCLUSIONS These data provide new evidence that low doses of scopolamine and intermediate doses of methamphetamine might therapeutically reduce compulsive behaviors and suggest that there is not a direct participation of the endocannabinoid system in compulsive behavior on SIP. The research in the underlying neurochemical mechanisms of these psychoactive drugs might provide an additional insight on new therapeutic targets in compulsive neuropsychiatric disorders.

Abstract
BACKGROUND Serotonergic antidepressants are first-line medication therapies for obsessive-compulsive disorder, however it is not known if synaptic serotonin availability is important for selective serotonin reuptake inhibitor efficacy. The present study tested the hypothesis that temporary reduction in central serotonin transmission, through acute tryptophan depletion, would result in an increase in anxiety in selective serotonin reuptake inhibitor-remitted obsessive-compulsive disorder patients. METHODS Eight patients (four males) with obsessive-compulsive disorder who showed sustained clinical improvement with selective serotonin reuptake inhibitor treatment underwent acute tryptophan depletion in a randomized, double-blind, placebo-controlled, within-subjects design, over two days one week apart. Five hours after consumption of the depleting/sham drink the participants performed a personalized obsessive-compulsive disorder symptom exposure task. Psychological responses were measured using the Spielberger State Anxiety Inventory, Yale-Brown Obsessive Compulsive Scale and Visual Analogue Scales. RESULTS Free plasma tryptophan to large neutral amino acid ratio decreased by 93% on the depletion day and decreased by 1% on the sham day, as anticipated. Psychological rating scores as measured by Visual Analogue Scale showed a significant decrease in perceived control and increase in interfering thoughts at the time of provocation on the depletion day but not on the sham day. A measure of convergent validity, namely Visual Analogue Scale Similar to past, was significantly higher at the time of provocation on both the depletion and sham days. Both the depletion and time of provocation scores for Visual Analogue Scale Anxiety, Spielberger State Anxiety Inventory, Yale-Brown Obsessive Compulsive Scale and blood pressure were not significant. CONCLUSIONS Acute tryptophan depletion caused a significant decrease in perceived control and increase in interfering thoughts at the time of provocation. Acute tryptophan depletion had no effect on the Spielberger State Anxiety Inventory or Visual Analogue Scale Anxiety measures, which suggests that the mechanism of action of selective serotonin reuptake inhibitors may be different to that seen in panic, social anxiety and post-traumatic stress disorder. Successful selective serotonin reuptake inhibitor treatment of obsessive-compulsive disorder may involve the ability of serotonin to switch habitual responding to goal-directed behaviour.

Abstract
INTRODUCTION/OBJECTIVE The aim was to measure the lifetime prevalence of panic disorder (PD) in an Italian community sample, and to estimate the burden attributable to PD in compromising the quality of life (QoL) of people diagnosed with it. METHODS Community survey was conducted on a sample of 4,999 randomly selected adult subjects. Instruments used were semi-structured clinical interview Advanced Neuropsychiatric Tools and Assessment Schedule (ANTAS), administered by clinicians and allowing diagnosis according to Diagnostic and Statistical Manual of Mental Disorder (4th ed.; DSM-IV); Short Form Health Survey (SF-12). RESULTS The lifetime prevalence of PD was 3.6% (4.4% in females, 2.5% in males; p = .002). People with PD had a lower SF-12 score than the standardized community sample (35.5 ± 6.5 vs. 38.4 ± 5.9; p < .0001) with a mean difference (attributable burden) of 2.9 ± 0.7, that is, lower than PD with agoraphobia (AP; 4.2 ± 2.4). Wilson Disease (WD), Multiple Sclerosis, Major Depressive Disorder and Eating Disorders (ED) show a higher attributable burden in impaired QoL than PD, while the attributable burden of PD with AP is not lower than in ED and WD. CONCLUSIONS The burden attributable to the impairment of QoL following a lifetime diagnosis of PD was found to be not so great compared to the impairment caused by Major Depressive Disorder (MDD) or neurological conditions. The comorbidity of PD with AP worsens QoL significantly.

Abstract
Irritable bowel syndrome (IBS) is a functional syndrome characterized by chronic abdominal pain accompanied by altered bowel habits. Although generally considered a functional disorder, there is now substantial evidence that IBS is associated with a poor quality of life and significant negative impact on work and social domains. Neuroimaging studies documented changes in the prefrontal cortex, ventro-lateral and posterior parietal cortex and thalami, and implicate alteration of brain circuits involved in attention, emotion and pain modulation. Emerging data reveals the interaction between psychiatric disorders including generalized anxiety disorder, panic disorder, major depressive disorder, bipolar disorder, and schizophrenia and IBS, which suggests that this association should not be ignored when developing strategies for screening and treatment. Psychological, social and genetic factors appear to be important in the development of IBS symptomatology through several mechanisms: alteration of HPA axis modulation, enhanced perception of visceral stimuli or psychological vulnerability. Elucidating the molecular mechanisms of IBS with or without psychiatric comorbidities is crucial for elucidating the pathophysiology and for the identification of new therapeutical targets in IBS.
