Abstract
OCD is characterized by obsessions (recurrent, intrusive, unwanted thoughts, images or impulses and compulsions (repetitive behaviors or mental acts that the individual feels compelled to perform), which can manifest together or separately (Fineberg et al., 2020). NICE guidelines suggest that low intensity psychological treatments (including ERP) is the first line treatment for OCD, and that a "stepped care" treatment approach for OCD reserves combination treatment for adults with OCD with severe functional impairment, and for adults without an adequate response to: 1) treatment with an SSRI alone (12 weeks duration) or 2) CBT (including ERP) alone (NICE, 2005). Existing US treatment guidelines (APA guidelines) suggest that there are three first-line treatments for OCD (SSRI, CBT, SSRI+CBT) and recommends combined treatment for patients with an unsatisfactory response to monotherapy or for patients with severe OCD. Although, systematic review and meta-analysis of studies published in 1993-2014 suggest that combination treatment was not significantly better than CBT plus placebo (Ost et al., 2015), based on data from a recent systematic and meta-analysis which searched the two controlled trials registers maintained by the Cochrane Collaboration Common Mental Disorders group, the combination treatment approach is likely to be more effective than psychotherapeutic interventions alone, at least in severe obsessive-compulsive disorder (Skapinakis et al., 2016a). Based on data from Optimal treatment for OCD study conducted by Fineberg et al., (2018) combined treatment appeared to be the most effective especially when compared to CBT monotherapy, but SSRI monotherapy was found as the most cost effective. In this review we summarize available treatment recommendations.

Abstract
Current treatments for autism spectrum disorders (ASD) are limited in efficacy and are often associated with substantial side effects. These medications typically ameliorate problem behaviors associated with ASD, but do not target core symptom domains. As a result, there is a significant amount of research underway for development of novel experimental therapeutics. Endocannabinoids are arachidonic acid-derived lipid neuromodulators, which, in combination with their receptors and associated metabolic enzymes, constitute the endocannabinoid (EC) system. Cannabinoid signaling may be involved in the social impairment and repetitive behaviors observed in those with ASD. In this review, we discuss a possible role of the EC system in excitatory-inhibitory (E-I) imbalance and immune dysregulation in ASD. Novel treatments for the core symptom domains of ASD are needed and phytocannabinoids could be useful experimental therapeutics for core symptoms and associated domains.

Abstract
Obsessive-compulsive disorder (OCD) sits at the epicenter of a spectrum of related conditions (often referred to as obsessive-compulsive related disorders (OCRD) or obsessive-compulsive spectrum disorders (OCSD)) that can be as disabling as they are varied in presentation. Research in the field now encompasses diverse disciplines ranging from inflammatory mechanisms to computational psychiatry, to neurocognitive endophenotypes to functional imaging to pharmacogenomics to brain stimulation approaches. As these disorders become more clearly elucidated, there is a need to continually re-evaluate the implications of research findings and to incorporate these findings into new treatment approaches that benefit both patients and clinicians. Even the Diagnostic and Statistical Manual of Mental Disorders 5th Edition (DSM-5) is intended to be flexible and to incorporate validated and reliable biomarkers and neuroscience findings as they become available. This concluding chapter highlights just a few areas of study that promise to influence our understanding of the pathophysiology and clinical practice of OCRD. These include patient-centered outcomes research, the study of developmental brain trajectories in spectrum conditions, robot models of OCRDs, goal-directed versus habit-based behaviors, pharmacogenomics, problematic use of the Internet, and digital interventions. For example, digital medicine may become increasingly useful by identifying patients early on in the course of their illness; providing biomarkers to subtype patients; predicting treatment response; serving as a more proximal outcome measure of treatment response; or providing easily accessible and less costly forms of care. In order to address unmet clinical needs in OCRD, it is helpful to take an interdisciplinary perspective, and the work described in this collection of articles is likely to be invaluable in shaping the future of the field.

Abstract
The Internet is now all-pervasive across much of the globe. While it has positive uses (e.g. prompt access to information, rapid news dissemination), many individuals develop Problematic Use of the Internet (PUI), an umbrella term incorporating a range of repetitive impairing behaviours. The Internet can act as a conduit for, and may contribute to, functionally impairing behaviours including excessive and compulsive video gaming, compulsive sexual behaviour, buying, gambling, streaming or social networks use. There is growing public and National health authority concern about the health and societal costs of PUI across the lifespan. Gaming Disorder is being considered for inclusion as a mental disorder in diagnostic classification systems, and was listed in the ICD-11 version released for consideration by Member States (http://www.who.int/classifications/icd/revision/timeline/en/). More research is needed into disorder definitions, validation of clinical tools, prevalence, clinical parameters, brain-based biology, socio-health-economic impact, and empirically validated intervention and policy approaches. Potential cultural differences in the magnitudes and natures of types and patterns of PUI need to be better understood, to inform optimal health policy and service development. To this end, the EU under Horizon 2020 has launched a new four-year European Cooperation in Science and Technology (COST) Action Programme (CA 16207), bringing together scientists and clinicians from across the fields of impulsive, compulsive, and addictive disorders, to advance networked interdisciplinary research into PUI across Europe and beyond, ultimately seeking to inform regulatory policies and clinical practice. This paper describes nine critical and achievable research priorities identified by the Network, needed in order to advance understanding of PUI, with a view towards identifying vulnerable individuals for early intervention. The network shall enable collaborative research networks, shared multinational databases, multicentre studies and joint publications.

Abstract
INTRODUCTION Obsessive-compulsive disorder (OCD) is a highly disabling condition, with frequent early onset. Adult/adolescent OCD has been extensively investigated, but little is known about prevalence and clinical characterization of geriatric patients with OCD (G-OCD≥65years). The present study aimed to assess prevalence of G-OCD and associated socio-demographic and clinical correlates in a large international sample. METHODS Data from 416 outpatients, participating in the ICOCS network, were assessed and categorized into 2 groups, age<vs≥65years, and then divided on the basis of the median age of the sample (age<vs≥42years). Socio-demographic and clinical variables were compared between groups (Pearson Chi-squared and t tests). RESULTS G-OCD compared with younger patients represented a significant minority of the sample (6% vs 94%, P<.001), showing a significantly later age at onset (29.4±15.1 vs 18.7±9.2years, P<.001), a more frequent adult onset (75% vs 41.1%, P<.001) and a less frequent use of cognitive-behavioural therapy (CBT) (20.8% vs 41.8%, P<.05). Female gender was more represented in G-OCD patients, though not at a statistically significant level (75% vs 56.4%, P=.07). When the whole sample was divided on the basis of the median age, previous results were confirmed for older patients, including a significantly higher presence of women (52.1% vs 63.1%, P<.05). CONCLUSIONS G-OCD compared with younger patients represented a small minority of the sample and showed later age at onset, more frequent adult onset and lower CBT use. Age at onset may influence course and overall management of OCD, with additional investigation needed.

Abstract
BACKGROUND Clinical studies have shown that repetitive transcranial magnetic stimulation (rTMS) is effective in a certain percentage of treatment-resistant depression (TRD). The left dorsolateral prefrontal cortex (DLPFC) 10 Hz rTMS stimulation received FDA approval in 2008, although different rTMS protocols have also shown their effectiveness in reducing depressive symptoms. We investigated the clinical, cognitive and neurophysiologic effects of a 3 weeks' protocol of low-frequency rTMS applied over the right DLPFC in resistant depression. METHODS Twenty-eight patients with TRD (age range 28-55) received low-frequency rTMS (1 Hz) over the right DLPFC in a 3-week open trial. Hamilton scales for depression and anxiety, Corsi block-tapping test, phonemic verbal fluency, right and left resting motor thresholds were evaluated in each subject over the trial period. RESULTS At the end of the trial 42.9% of the subjects were considered as responders. A significant reduction of both HAMD (p < 0.001) and HAMA (p < 0.01) total scores was observed. At the 3rd week, the performances in Corsi test (p < 0.02) and phonemic verbal fluency (p = 0.065) were improved independently from depressive symptoms variation. At the end of the rTMS protocol, a significantly decreased left hemisphere resting motor threshold was registered (p < 0.01), while right hemisphere resting motor threshold did not show significant variation. CONCLUSION Low-frequency rTMS over the right DLPFC appeared effective in 42.9% of depressive resistant subjects in this sample. A significant decrease in left hemisphere resting motor threshold was observed only in responders, while a trend for improvement in cognitive function has been found and appeared independent from clinical response.

Abstract
Obesity is a major problem of modern societies that sometimes, but not necessarily, is associated with binge-eating disorder (BED), a relatively new disorder characterized by binge eating without purging. The purpose of this article is to review the rationale for the potential use of pharmacological treatments in BED, and the potential use of the recently proposed compounds. Therefore, a careful medline of published articles from 1980 to December 2010 was carried out using the following keywords: BED and treatment, topiramate, zonisamide, sibutramine, venlafaxine, duloxetine, ghrelin, opiate blockers. Single case reports, observational studies, opinion articles, and studies concerning adults with syndromes resulting in BED (i.e., night eating syndrome) were also reviewed. All examined papers would indicate that the pharmacological treatment of BED is still heterogenous and poorly established, mainly for the lack of controlled studies in large samples of patients. In any case, the data on serotonin and norepinephrine reuptake inhibitors and on novel anticonvulsants seem quite promising in terms of efficacy and tolerability. In addition, the preliminary findings on the possibility of modulating appetite through the interference with the ghrelin system suggest new and intriguing ways of intervention in BED.

Abstract
Obsessive-compulsive disorder (OCD) is characterized by obsessions (intrusive thoughts) and compulsions (repetitive ritualistic behaviours) leading to functional impairment. Accumulating evidence links these conditions with underlying dysregulation of fronto-striatal circuitry and monoamine systems. These abnormalities represent key targets for existing and novel treatment interventions. However, the brain bases of these conditions and treatment mechanisms are still not fully elucidated. Animal models simulating the behavioural and clinical manifestations of the disorder show great potential for augmenting our understanding of the pathophysiology and treatment of OCD. This paper provides an overview of what is known about OCD from several perspectives. We begin by describing the clinical features of OCD and the criteria used to assess the validity of animal models of symptomatology; namely, face validity (phenomenological similarity between inducing conditions and specific symptoms of the human phenomenon), predictive validity (similarity in response to treatment) and construct validity (similarity in underlying physiological or psychological mechanisms). We then survey animal models of OC spectrum conditions within this framework, focusing on (i) ethological models; (ii) genetic and pharmacological models; and (iii) neurobehavioural models. We also discuss their advantages and shortcomings in relation to their capacity to identify potentially efficacious new compounds. It is of interest that there has been rather little evidence of 'false alarms' for therapeutic drug effects in OCD models which actually fail in the clinic. While it is more difficult to model obsessive cognition than compulsive behaviour in experimental animals, it is feasible to infer cognitive inflexibility in certain animal paradigms. Finally, key future neurobiological and treatment research areas are highlighted.

Abstract
Oxytocin has known stress-reducing and attachment-enhancing effects. We thus hypothesized that oxytocin would attenuate emotional and hormonal responses to stress in borderline personality disorder (BPD). Fourteen BPD and 13 healthy control (HC) adults received 40 IU intranasal oxytocin or placebo in double-blind randomized order followed by the Trier Social Stress Test. Subjective dysphoria (Profile of Mood Changes) and plasma cortisol levels were measured. Childhood trauma history, attachment style, and self-esteem were also rated. A significant "Group × Drug × Time" interaction effect for dysphoria (p=.04) reflected a proportionately greater attenuation of stress-induced dysphoria in the BPD group after oxytocin administration. Additionally, a marginally significant "Group × Drug" interaction effect for cortisol (p=.10) reflected a tendency toward greater attenuation of the stress-induced cortisol surge in the BPD group after oxytocin administration. In the combined sample, the oxytocin-placebo difference in the emotional stress reactivity was significantly predicted by childhood trauma alone (p=.037) and combined with self-esteem (p=.030), whereas the oxytocin-placebo difference in cortisol stress reactivity was predicted only by insecure attachment (p=.013). Results suggest that oxytocin may have a beneficial impact on emotional regulation in BPD, which merits further investigation and could have important treatment implications.

Abstract
The noradrenergic system has been linked to impulsive behaviour in animals and humans, yet little data on noradrenergic system exist in specific impulse control disorders. To explore the role of the noradrenergic system in pathological gamblers (PG), we assessed neuroendocrine growth hormone (GH) response to the alpha2-adrenergic receptor agonist clonidine and placebo in PG and controls. The net effects of clonidine are a decrease in neurotransmission by depressing locus coeruleus activity and stimulation of GH secretion through activation of post-synaptic alpha2-adrenergic receptors in the hypothalamus. Twenty-nine PG subjects, free of other comorbid conditions, and 27 healthy controls received a double-blinded, placebo-controlled, single dose of oral clonidine (0.15 mg/kg). Data observed included GH, clonidine levels and levels of the main noradrenergic metabolite, 3-methoxy-4-hydroxy-phenylglycol (MHPG). The area under the curve for GH response to clonidine was significantly lower (separate variance t with 44.3 df = 2.626, P = 0.012, d = 0.58) in the PG group (199.6) than in the control group (426.3). PG had significantly blunted GH responses compared with controls at 120 and 150 min post-clonidine. These results are consistent with the idea that the subsensitivity of post-synaptic alpha-2 receptors is possibly attributable to higher-than-normal noradrenergic secretion in PG. This peripheral noradrenergic dysfunction could be consistent with attenuated cortico-frontal noradrenergic function as shown in positron emission tomography (PET) studies of PG.

Abstract
OBJECTIVES The Duration of Untreated Illness (DUI), defined as the time elapsing between the onset of a disorder and the beginning of the first pharmacological treatment, has been increasingly investigated as a predictor of outcome and course across different psychiatric disorders. Purpose of this naturalistic study was to evaluate the influence of DUI on treatment response and remission in a sample of patients with obsessive-compulsive disorder (OCD). METHODS Sixty-six outpatients with a DSM-IV diagnosis of OCD were included in the study. Patients received, according to their clinical conditions, an open pharmacological treatment of 12 weeks and were evaluated by the administration of the Yale Brown Obsessive Compulsive Scale (Y-BOCS) at baseline and endpoint. Treatment response was defined as a decrease .25% on Y-BOCS score compared to baseline, while remission was defined as an endpoint Y-BOCS total score #10. A logistic regression was performed considering DUI as the independent continuous variable and treatment response and remission as the dependent variables. Moreover, the sample was divided into two groups according to a categorical cut-off for the DUI of 24 months and odds ratios (OR) were calculated on the basis of the same variables. RESULTS DUI, considered as a continuous variable, was not predictive of treatment response (OR51.00, P50.15) nor remission (OR51.00, P50.59). When considered as a categorical variable, however, a DUI # 24 months was predictive of treatment response (OR50.27, P50.03). CONCLUSIONS Results from the present naturalistic study suggest a complicated relationship between DUI and treatment outcome in OCD encouraging further investigation with larger samples in order to better define long versus short DUI in this condition.

Abstract
BACKGROUND AND PURPOSE Experimental studies suggest that deep brain stimulation (DBS) of the subthalamic nucleus (STN) induces impulsivity in patients with Parkinson's disease (PD). The purpose of this study was to assess various measures of impulse control in PD patients with STN DBS in comparison to patients receiving medical therapy. METHODS In a cross-sectional evaluation, 53 consecutively eligible patients were assessed for impulsivity with the Barratt Impulsiveness Scale, for impulse control disorders (ICDs) using the Minnesota Impulsive Disorders Interview, and for obsessive-compulsive symptoms using the Maudsley Obsessional-Compulsive Inventory. RESULTS Independent samples t-tests revealed that compulsivity scores were not different between DBS patients and patients without DBS. However, impulsivity scores were significantly higher in DBS patients. Additionally, ICDs were observed in 3 of 16 (19%) DBS patients and in 3 of 37 (8%) medically treated patients. No association was found between the use of dopamine agonists and impulsivity in DBS patients. CONCLUSIONS Our data suggest that screening for impulsivity and ICDs should be performed prior to DBS, and that patients should be monitored for these problems during follow-up. Prospective trials are needed to confirm the findings of this exploratory study and to elucidate the reasons of a possible induction of impulsivity by STN DBS.

Abstract
Obsessive-compulsive disorder (OCD) is currently recognised as one of the most common psychiatric disorders as well as one of the most disabling of all medical disorders. Obsessive-compulsive related disorders (OCRDs), often comorbid with OCD, include many distinct psychiatric conditions (i.e. some somatoform disorders, eating disorders, impulse control disorders and some neurological conditions) which have overlapping symptoms and compulsive qualities with OCD. Although effective treatments exist, OCD and related disorders are often underdiagnosed and undertreated. Serotonin reuptake inhibitors (SRIs) and cognitive behavioural therapy (CBT) represent the first-line treatment for OCD and related disorders. However, the time and the doses of the medications used in the treatment of OCD and related disorders differ from those recommended in depressive disorders. In addition, remission is not common for patients with OCD and related disorders in clinical practice, and poor responders as well as refractory cases may benefit from different treatment strategies including integrated treatment, pharmacological augmentation and brain stimulation techniques.

Abstract
Obsessive-compulsive disorder (OCD) encompasses a broad range of symptoms representing multiple domains. This complex phenotype can be summarized using a few consistent and temporally stable symptom dimensions. The objective of this study was to assess the psychometric properties of the Dimensional Yale-Brown Obsessive-Compulsive Scale (DY-BOCS). This scale measures the presence and severity of obsessive-compulsive (OC) symptoms within six distinct dimensions that combine thematically related obsessions and compulsions. The DY-BOCS includes portions to be used as a self-report instrument and portions to be used by expert raters, including global ratings of OC symptom severity and overall impairment. We assessed 137 patients with a Diagnostic and Statistical Manual-IV diagnosis of OCD, aged 6-69 years, from sites in the USA, Canada and Brazil. Estimates of the reliability and validity of both the expert and self-report versions of the DY-BOCS were calculated and stratified according to age (pediatric vs. adult subjects). The internal consistency of each of the six symptom dimensions and the global severity score were excellent. The inter-rater agreement was also excellent for all component scores. Self-report and expert ratings were highly intercorrelated. The global DY-BOCS score was highly correlated with the total Yale-Brown Obsessive-Compulsive Scale score (Pearson r = 0.82, P<0.0001). Severity scores for individual symptom dimensions were largely independent of one another, only modestly correlated with the global ratings, and were also differentially related to ratings of depression, anxiety and tic severity. No major differences were observed when the results were stratified by age. These results indicate that the DY-BOCS is a reliable and valid instrument for assessing multiple aspects of OCD symptom severity in natural history, neuroimaging, treatment response and genetic studies when administered by expert clinicians or their highly trained staff.

Abstract
Although there is considerable evidence for a strong genetic component to idiopathic autism, several genome-wide screens for susceptibility genes have been carried out with limited concordance of linked loci, reflecting numerous genes of weak effect and/or sample heterogeneity. In the current study, linkage analysis was carried out in a sample of 62 autism-affected relative pairs with more severe obsessive-compulsive behaviors, selected from a larger (n=115) set of autism-affected relative pairs as a means of reducing sample heterogeneity. Obsessive-compulsive behaviors were assessed using the Autism Diagnostic Interview-Revised (ADI-R). In the sample with more severe obsessive-compulsive behaviors, multipoint NPL scores above 2 were observed on chromosomes 1, 4, 5, 6, 10, 11 and 19, with the strongest evidence for linkage on chromosome 1 at the marker D1S1656, where the multipoint NPL score was 3.06, and the two-point NPL score was 3.21. In follow-up analyses, analyzing the subset of families (n=35) where the patients had the most severe obsessive-compulsive behaviors generated a multipoint NPL score of 2.76, and a two-point NPL score of 2.79, indicating that the bulk of evidence for linkage was derived from the families most severely affected with obsessive-compulsive behaviors. The data suggest that there is an autism susceptibility gene on chromosome 1 and provide further support for the presence of autism susceptibility genes on chromosomes 6 and 19.

Abstract
The current study examines the neuroendocrine response to intravenous clomipramine (IV CMI) in oral CMI-resistant obsessive-compulsive disorder (OCD) patients on day 1 and day 14 of treatment to identify predictors of response. Forty-four OCD patients with an inadequate response or poorly tolerant to oral CMI were begun at 25 mg IV CMI, increasing to 250 mg by day 10, and continuing on that dose to day 14. On day 1, plasma levels of prolactin (PRL), growth hormone (GH), and cortisol were obtained immediately before the 25 mg IV infusion, and at five 30-minute time points after the infusion. On day 14, hormonal samples were obtained in a similar fashion. Response was assessed by the Clinical Global Impressions (CGI). Low PRL(MAX) to IV CMI and low cortisol levels overall on day 1 were both significantly associated with clinical response at day 14. An overall increase in growth hormone (GH) secretion during the day 14 testing was associated with positive response. A pronounced PRL response to IV CMI on day 14 was exhibited by the nonresponders, whereas a smaller and later but significant increase in PRL was noted in the responders. The findings suggest that in this sample of oral CMI-resistant patients with OCD, neuroendocrine measures derived from pharmacological challenge with IV CMI are capable of distinguishing IV CMI treatment responders from nonresponders. The limitations of IV CMI as a specific probe of serotonin function are discussed.

Abstract
BACKGROUND The purpose of this preliminary study was to investigate HPA axis function in dissociation. METHODS Nine subjects with DSM-IV depersonalization disorder (DPD), without lifetime Posttraumatic Stress Disorder (PTSD) or current major depression, were compared to nine healthy comparison (HC) subjects of comparable age and gender. RESULTS DPD subjects demonstrated significant hyposuppression to low-dose dexamethasone administration and significantly elevated morning plasma cortisol levels when covaried for depression scores, but no difference in 24-hour urinary cortisol excretion. Dissociation scores powerfully predicted suppression whereas depression scores did not contribute to the prediction. CONCLUSIONS Primary dissociative conditions, such as depersonalization disorder, may be associated with a pattern of HPA axis dysregulation that differs from PTSD and merits further study.

Abstract
BACKGROUND Autism spectrum disorders are characterized by core deficits in social interaction and speech/communication skills, repetitive behaviors, and restricted interests. Other abnormalities include seizures, electroencephalographic (EEG) abnormalities, affective instability, impulsivity, and aggression. Divalproex sodium is indicated as both an anticonvulsant in epilepsy and a mood stabilizer in bipolar illness and thus might be useful for these complicating symptoms in autism. METHOD A retrospective pilot study was conducted to determine whether divalproex sodium was effective in treating core dimensions and associated features of autism. Fourteen patients who met DSM-IV criteria for autism, Asperger's disorder, or pervasive developmental disorder not otherwise specified, both with and without a history of seizure disorders or EEG abnormalities, were openly treated with divalproex sodium. Improvement was assessed via the Clinical Global Impressions-Improvement scale. RESULTS Of 14 patients who completed a trial of divalproex sodium, 10 (71%) were rated as having sustained response to treatment. The mean dose of divalproex sodium was 768 mg/day (range, 125-2500 mg/day), and it was generally well tolerated. Improvement was noted in core symptoms of autism and associated features of affective instability, impulsivity, and aggression. CONCLUSION Divalproex sodium may be beneficial to patients with autism spectrum disorders, particularly those with associated features of affective instability, impulsivity, and aggression as well as those with a history of EEG abnormalities or seizures. Of note, all patients with an abnormal EEG and/or seizure history were rated as responders. However, these findings must be interpreted with caution, given the open retrospective nature of the study. Controlled trials are needed to replicate these preliminary findings.

Abstract
The regional metabolic effects of fluoxetine were examined in patients with autism spectrum disorders. Six adult patients with DSM-IV and Autism Diagnostic Interview (ADI) diagnoses of autism (n = 5) and Asperger's syndrome (n = 1), entered a 16-wk placebo-controlled cross-over trial of fluoxetine. The patients received (18)F-deoxyglucose positron emission tomography with co-registered magnetic resonance imaging at baseline and at the end of the period of fluoxetine administration. After treatment, the patients showed significant improvement on the scores of the Yale--Brown Obsessive--Compulsive Scale -- Obsessions subscale and the Hamilton Anxiety Scale; Clinical Global Impressions -- Autism scores showed 3 of the patients much improved and 3 unchanged. Relative metabolic rates were significantly higher in the right frontal lobe following fluoxetine, especially in the anterior cingulate gyrus and the orbitofrontal cortex. Patients with higher metabolic rates in the medial frontal region and anterior cingulate when unmedicated were more likely to respond favourably to fluoxetine. These results are consistent with those in depression indicating that higher cingulate gyrus metabolic rates at baseline predict SRI response.

Abstract
Although there is considerable evidence for a strong genetic component to idiopathic autism, several genomewide screens for susceptibility genes have been performed with limited concordance of linked loci, reflecting either numerous genes of weak effect and/or sample heterogeneity. Because decreasing sample heterogeneity would increase the power to identify genes, the effect on evidence for linkage of restricting a sample of autism-affected relative pairs to those with delayed onset (at age >36 mo) of phrase speech (PSD, for phrase speech delay) was studied. In the second stage of a two-stage genome screen for susceptibility loci involving 95 families with two or more individuals with autism or related disorders, a maximal multipoint heterogeneity LOD score (HLOD) of 1.96 and a maximal multipoint nonparametric linkage (NPL) score of 2.39 was seen on chromosome 2q. Restricting the analysis to the subset of families (n=49) with two or more individuals having a narrow diagnosis of autism and PSD generated a maximal multipoint HLOD score of 2.99 and an NPL score of 3.32. The increased scores in the restricted sample, together with evidence for heterogeneity in the entire sample, indicate that the restricted sample comprises a population that is more genetically homogeneous, which could therefore increase the likelihood of positional cloning of susceptibility loci.

Abstract
The neurochemical specificity of physiological, biochemical, and psychological responses to dextroamphetamine was tested by pretreating volunteers with haloperidol (0.014 mg/kg IM), propranolol (0.1 mg/kg IV), thymoxamine (0.1 mg/kg IV), or placebo prior to 0.3 mg/kg IV amphetamine. Healthy volunteers (N = 12) participated in the studies, but not all volunteers received each drug combination. Haloperidol prevented dextroamphetamine-induced behavioral excitation, but did not significantly affect plasma norepinephrine or pressor responses, whereas propranolol inhibited norepinephrine and pressor responses without influencing excitation or other behavioral responses. Thymoxamine did not affect any of the responses measured. None of the agents significantly affected plasma cortisol or growth hormone responses. The prolactin rise following dextroamphetamine was potentiated by haloperidol. The results are consistent with the hypothesis that behavioral excitation after dextroamphetamine occurs through a dopaminergic mechanism, and pressor responses through a noradrenergic mechanism.

Abstract
BACKGROUND Borderline personality disorder is characterized by affective instability, impulsivity, and aggression and is associated with considerable morbidity and mortality. Since anticonvulsant agents may be helpful in such symptomatology, we compared divalproex sodium with placebo in patients with borderline personality disorder. METHOD A 10-week, parallel, double-blind design was conducted. Sixteen outpatients meeting Structured Clinical Interview for DSM-IV Axis II Personality Disorders criteria for borderline personality disorder were randomly assigned to receive placebo (N = 4) or divalproex sodium (N = 12). Change was assessed in global symptom severity (Clinical Global Impressions-Improvement Scale [CGI-I]) and functioning (Global Assessment Scale [GAS]) as well as in specific core symptoms (depression, aggression, irritability, and suicidality). RESULTS There was significant improvement from baseline in both global measures (CGI-I and GAS) following divalproex sodium treatment. A high dropout rate precluded finding significant differences between the treatment groups in the intent-to-treat analyses, although all results were in the predicted direction. CONCLUSION Treatment with divalproex sodium may be more effective than placebo for global symptomatology, level of functioning, aggression, and depression. Controlled trials with larger sample sizes are warranted to confirm these preliminary results.

Abstract
Disorders characterized by impulsivity include disorders of impulse control (intermittent explosive disorder, pyromania, kleptomania, pathological gambling and trichotillomania), paraphilias, sexual impulsions and sexual addictions and impulsive aggression personality disorders (borderline, antisocial, histrionic and narcissistic personality disorders). Impulsivity has a substantial impact on both individuals and society. Impulse control disorders may be conceptualized as a subset of the obsessive-compulsive spectrum. In this article, we examine the genetic and neurobiological aetiology of these disorders and possible treatment options. The link between serotonergic dysfunction and the pathophysiology of impulsivity is discussed, and studies that examine the efficacy of various selective serotonin reuptake inhibitors and other alternatives in the treatment of impulsive disorders such as pathological gambling, sexual addictions and borderline personality disorder are presented.

Abstract
OBJECTIVE Cytoarchitectonic changes in the anterior cingulate cortex, hippocampus, subiculum, entorhinal cortex, amygdala, mammillary bodies, and septum were reported in a postmortem study of autism. Previously, the authors found smaller cingulate volume and decreased metabolism of the cingulate in seven autistic patients. In this study, they measured the volume and glucose metabolism of the amygdala, hippocampus, and cingulate gyrus in an expanded group of 17 patients with autism spectrum disorders (autism [N=10] or Asperger's disorder [N=7]) and 17 age- and sex-matched healthy volunteers. METHOD Subjects performed a serial verbal learning test during (18)F-deoxyglucose uptake. The amygdala, hippocampus, and cingulate gyrus were outlined on magnetic resonance imaging scans, volumes of the structures were applied to matching coregistered positron emission tomography scans, and three-dimensional significance probability mapping was performed. RESULTS Significant metabolic reductions in both the anterior and posterior cingulate gyri were visualized in the patients with autism spectrum disorders. Both Asperger's and autism patients had relative glucose hypometabolism in the anterior and posterior cingulate as confirmed by analysis of variance; regional differences were also found with three-dimensional significance probability mapping. No group differences were found in either the metabolism or the volume of the amygdala or the hippocampus. However, patients with autism spectrum disorders showed reduced volume of the right anterior cingulate gyrus, specifically in Brodmann's area 24'. CONCLUSIONS Compared with age- and sex-matched healthy volunteers, patients with autism spectrum disorders showed significantly decreased metabolism in both the anterior and posterior cingulate gyri.

Abstract
OBJECTIVE The goal of this study was to assess brain glucose metabolism and its relationship to dissociation measures and clinical symptoms in DSM-IV depersonalization disorder. METHOD Positron emission tomography scans coregistered with magnetic resonance images of eight subjects with depersonalization disorder were compared to those of 24 healthy comparison subjects. The two groups did not differ in age, sex, education, performance on a baseline neuropsychological battery, or performance on a verbal learning task administered during [(18)F]fluorodeoxyglucose uptake. A cortical analysis by individual Brodmann's areas was performed. RESULTS Compared to the healthy subjects, subjects with depersonalization disorder showed significantly lower metabolic activity in right Brodmann's areas 22 and 21 of the superior and middle temporal gyri and had significantly higher metabolism in parietal Brodmann's areas 7B and 39 and left occipital Brodmann's area 19. Dissociation and depersonalization scores among the subjects with depersonalization disorder were significantly positively correlated with metabolic activity in area 7B. CONCLUSIONS Depersonalization appears to be associated with functional abnormalities along sequential hierarchical areas, secondary and cross-modal, of the sensory cortex (visual, auditory, and somatosensory), as well as areas responsible for an integrated body schema. These findings are in good agreement with the phenomenological conceptualization of depersonalization as a dissociation of perceptions as well as with the subjective symptoms of depersonalization disorder.

Abstract
Different observations show a reduced functionality of the serotonin (5-HT) transporter in obsessive-compulsive disorder (OCD) that might be due to a disturbance of its regulation at intracellular level. Protein kinase C (PKC) has been reported to provoke a decrease in the number of the 5-HT transporter proteins. Therefore, we investigated whether OCD patients differed from control subjects in the effect of PKC upon the 5-HT transporter, after stimulation of this enzyme with 4beta-12-tetradecanoylphorbol 13-acetate (beta-TPA). Fifteen patients affected by OCD, according to DSM-IV criteria, were compared with a similar group of healthy subjects. The determination of 5-HT uptake was carried out according to the method of Arora and Meltzer with slight modifications. At baseline, OCD patients showed a significant decrease in the maximal velocity (V(max)) of 5-HT uptake, as compared with control subjects, with no change in the Michaelis-Menten constant (K(m)). The activation of PKC with beta-TPA provoked a significant decrease in V(max) values in both groups, but the effect was significantly more robust in OCD patients who, in turn, also showed also an increase in K(m) values. These findings could indicate the presence of hyperactivity of PKC in OCD that could be the result of increased activity of the phosphatidylinositol pathway. In addition, this suggests new potential therapeutic targets in OCD.

Abstract
The understanding of BDD and its treatment has expanded significantly in the past decade as controlled research has followed the leads from case reports and clinical experience. BDD is recognized as a severe, disabling disorder that is more common that had been assumed. Although BDD is still difficult to treat, success has been demonstrated for SRIs and CBT. Much remains to be discovered. To date, little is known about the causes and pathophysiology of BDD. Research that would illuminate these also would increase understanding of its relationship to other disorders, such as OCD, depression, and social phobia, and open up possibilities for prevention and new approaches to treatment. Investigations in brain imaging and genetics are underway. Research in pharmacotherapy and CBT, individually and combined, is needed to refine, extend, and optimize treatment.

Abstract
With increasing access to gambling facilities through casinos, the Internet, and other venues, PG is a rapidly emerging mental health concern. This impulse-control disorder tends to be comorbid with a wide range of other disorders and is reportedly associated with a high rate of suicide. For most gamblers, gambling is a form of entertainment, but for many individuals, the activity leads to far-reaching disruption of family and work. The personal and societal financial ramifications are severe, and many individuals with PG end up in the criminal justice system. An understanding of the neurobiology of PG is beginning to surface. 5-HT is linked to behavioral initiation and disinhibition, which are important in the onset of the gambling cycle and the difficulty in ceasing the behavior. Norepinephrine is associated with the arousal and risk taking in patients with PG. Dopamine is linked to positive and negative reward, the addictive component of this disorder. Effective treatment strategies for pathological gamblers are emerging. Potentially useful pharmacologic agents include SRIs (clomipramine and fluvoxamine), mood stabilizers for pathological gamblers with comorbid bipolar disorders (lithium), and naltrexone. Cognitive-behavioral psychotherapies offer promising results in the treatment of patients with this disorder. To devise prevention and early-intervention programs, research is needed to identify specific features of the individuals at risk for gambling problems. Education targeting vulnerable youth that show early signs of gambling behavior may be worthwhile and should be investigated further. Funding is necessary to support these endeavors, so perhaps a portion of tax revenues generated from the gambling industry should go toward specialized treatment facilities, educational efforts, and research into the neurobiology and treatment of PG.

Abstract
SSRIs and the tricyclic antidepressant clomipramine are the first-line therapies for patients with OCD, with the side-effect profile of SSRIs being more favorable than that of clomipramine. As many as 40% to 60% of patients with OCD may not respond to adequate trials of SRIs. Not all patients tolerate SSRIs, and delays in full therapeutic responses often occur. Thus, other pharmacologic approaches to treating patients with OCD have been investigated. Augmentation and monotherapy have been explored with serotonergic enhancers, dopamine and 5-HT antagonists, enhancers of second-messenger systems, and GABAergic agents with varying efficacy.

Abstract
The introduction of the SSRIs (selective serotonin reuptake inhibitors) over the past decade has provided exciting new opportunities for the treatment of obsessive-compulsive disorder (OCD). The serotonin hypothesis, based on the preferential response of OCD to the serotonin reuptake inhibitor, clomipramine, paved the way for research into the efficacy of the SSRIs in the treatment of this disorder. Large, controlled, multicenter studies have found clomipramine and the SSRIs, fluoxetine, fluvoxamine, sertraline, and paroxetine, to be effective and safe in the treatment of OCD. Meta-analytic studies have reported that clomipramine is superior to the SSRIs; however, direct head-to-head comparisons suggest equal efficacy. As SSRIs have a more favorable side-effect profile they may be preferable as first-line treatment of OCD. Improvement following adequate OCD drug treatment is frequently partial whereupon augmentation strategies may become necessary. High rates of relapse have been reported on discontinuation of SRI treatment. Long-term maintenance treatment has been found to be effective in sustaining initial therapeutic gains and bringing about further improvement.

Abstract
Since the introduction of the selective serotonin reuptake inhibitors (SSRIs) a decade ago, they have become first-line agents in the treatment of obsessive-compulsive disorder (OCD). Numerous clinical trials have confirmed their efficacy, and established their superior risk-benefit ratio in comparison with clomipramine, a non-selective serotonin reuptake inhibitor. Relatively higher doses and longer duration of treatment may be necessary to effect a response in OCD, with long-term treatment being required to maintain therapeutic gains. Despite the advances represented by the SSRIs, treatment resistance remains a problem. While no one solution exists, various strategies, including pharmacotherapy augmentation, look promising.

Abstract
Serotonergic (5-HT) abnormalities have been documented in autism. To assess sensitivity of the 5-HT1d receptor, growth hormone response to the 5-HT1d receptor agonist sumatriptan was studied in adult autistic patients and matched normal controls. In this study, 11 adult patients with autism or Asperger's disorder were compared with nine matched controls. All subjects were randomized to single dose sumatriptan (6 mg SQ) and placebo challenges, separated by a 1-week interval, and growth hormone was measured before and during the challenges. The results showed a highly significant diagnosisxdrugxtime interaction on repeated measure analysis covaried for baseline. This suggests that autistic patients had significantly greater growth hormone response to sumatriptan than normal controls, independent of placebo effects. Therefore, abnormalities in 5-HT regulation in autism may be related to increased sensitivity of the 5-HT1d inhibitory receptor in autism.

Abstract
BACKGROUND The study assessed the efficacy and tolerability of the selective serotonin reuptake inhibitor (SSRI) fluvoxamine in the treatment of pathologic gambling (PG). METHODS A 16-week randomized double-blind crossover design insured that each subject received 8 weeks of fluvoxamine and 8 weeks of a placebo. Fifteen patients entered and 10 subjects, all male, completed the study. RESULTS Fluvoxamine resulted in a significantly greater percent improvement in overall gambling severity on the PG Clinical Global Impression (PG-CGI) scale. There was a significant drug effect on gambling urge and behavior as measured by the PG modification of the Yale-Brown Obsessive Compulsive Scale and PG-CGI scale improvement scores; however, there was a significant interaction of drug effect with the order of administration of drug and placebo. Post hoc analysis, treating each phase as a separate trial, demonstrated a significant difference between fluvoxamine and the placebo in the second phase of the trial but not in the first. Fluvoxamine side effects were of only mild intensity and consistent with SSRI treatment and were not associated with early withdrawal from the study. CONCLUSIONS These findings suggest that fluvoxamine is well tolerated and may be effective in the treatment of PG in an acute trial, and that an early placebo effect in PG treatment appears to diminish over time. To confirm this finding and to determine whether improvement persists over an extended period of time, a longer duration parallel-design trial with long-term maintenance follow-up should be conducted in a larger and more diverse PG population.

Abstract
UNLABELLED The involvement of brain serotonin systems in the pathophysiology of eating disorders has been repeatedly demonstrated in recent studies. Platelet MAO activity is an index of brain serotonin activity and lowered platelet MAO levels have been found in association with impulsive behaviors. In addition, some preliminary reports indicate that platelet MAO could be lowered in eating disorder patients. METHODS 47 patients with DSM-IV eating disorders were studied, including 30 with bulimia nervosa and 17 with anorexia nervosa binge eating-purging type. Platelet MAO activity was measured by isotopic methods using C-14 benzylamine and compared with a control group of 30 healthy subjects. Impulsive personality features were studied with specific rating scales. RESULTS Platelet MAO activity was significantly lower (4.4+/-2.4 nmol/h/10(8) platelets) in the bulimic patients than in the control group (6.9+/-2.5) (p<0.001). No significant differences were found between pure bulimics and binge eating-purging anorectics. Platelet MAO was inversely and significantly correlated with scores on impulsivity scales and with borderline personality disorder characteristics. CONCLUSIONS Platelet MAO activity is lowered in patients with bulimia, which may reflect dysfunction in impulse control mechanisms. Since platelet MAO has a predominant genetic component, there is need for studies on the association of low platelet MAO and higher risk for developing eating disorders.

Abstract
OBJECTIVE To study if platelet MAO activity, previously described as a serotonergic index, is modified in a sample of pure restrictive anorectic patients. METHOD Twenty-five female patients with DSM-IV anorexia nervosa restricting type were studied and compared with 30 healthy female controls. Platelet MAO activity was measured by isotopic methods using C-14 benzylamine. Impulsive personality features were measured with specific rating scales and temperament studied with Cloninger's TCI. RESULTS Platelet MAO activity was significantly lower (4.3+2.7 nmol/h/ 108 platelets) in the anorectic patients than in the control group (6.7+2.8) (P<0.01). Platelet MAO was inversely correlated with scores on impulsivity scales and positively correlated with the dimension 'persistence' of Cloninger's TCI. CONCLUSION Platelet MAO activity is lowered in a group of patients with anorexia nervosa and might involve some dysfunction in the regulation of impulse control.

Abstract
Autism is heterogeneous with respect to clinical symptoms and etiology. To sort out this heterogeneity in autism, we investigated whether specific neurobiological markers vary in parallel to core symptomatology. Specifically, we assessed growth hormone response to the 5-HT 1d agonist, sumatriptan, and linked this measure of serotonergic function to the severity of repetitive behaviors in adult autistic patients. Eleven adult patients with autism or Asperger's disorder were randomized to single dose sumatriptan (6 mg SQ) and placebo challenges, separated by a one-week interval. In adult autistic disorders, severity of repetitive behaviors at baseline, as measured by YBOCS-compulsion score, significantly positively correlated with both peak delta growth hormone response and area under the curve growth hormone response to sumatriptan. Thus, the severity of a specific behavioral dimension in autism (repetitive behaviors) parallels the sensitivity of the 5-HT 1d receptor, as manifest by sumatriptan elicited GH response.

Abstract
Autism is characterized by social deficits, communication and language impairments, narrow restricted interests, repetitive behaviors, inattention, and hyperactivity. While selective serotonin reuptake inhibitors have demonstrated efficacy in treating core symptoms of autism, norepinephrine reuptake inhibitors have demonstrated efficacy in symptoms of attention-deficit hyperactivity disorder (ADHD). An open, retrospective clinical study with venlafaxine evaluated its effect on core symptoms of autism as well as associated features of ADHD. Ten consecutive subjects meeting Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV), criteria for an autism spectrum disorder were treated with venlafaxine, initiated at 12.5 mg per day and adjusted on a flexible basis. Six of 10 completers were judged to be sustained treatment responders, by scoring 1 (very much improved) or 2 (much improved) on the Clinical Global Impressions improvement scale. Venlafaxine was effective in low dosages (mean, 24.37 mg/day; range, 6.25 to 50 mg/day) and was well tolerated. Improvement was noted in repetitive behaviors and restricted interests, social deficits, communication and language function, inattention, and hyperactivity. Controlled treatment trials with venlafaxine are warranted in autism spectrum disorders.

Abstract
Personality impairment was evaluated in 17 body dysmorphic disorder (BDD) patients undergoing a treatment study of clomipramine versus desipramine. Semistructured interviews were administered using both categorical (Structured Clinical Interview for DSM [SCID II]) and dimensional (Dimensional Assessment of Personality Impairment [DAPI]) methods. Personality measures were also correlated with a range of clinical variables (severity of BDD and depressive symptoms, age, duration of illness, and response to treatment). A secondary aim of the study was to provide preliminary validation for the DAPI. Consistent with previous studies, BDD patients showed considerable personality pathology. By SCID II, patients met criteria for a mean of 2.53 personality disorder diagnoses; 87% of patients met criteria for at least 1 diagnosis and 53% for more than 1. Cluster C diagnoses were the most common. Mean scores for the DAPI were 2.63 (3 = mild impairment) to 6.41 (7 = severe impairment), averaging 5.26 (5 = moderate). With regard to the DAPI, the results provided preliminary evidence of good reliability and validity. Moreover, both personality measures were highly intercorrelated. Although SCID II diagnoses correlated with baseline depression (Hamilton Rating Scale for Depression [HRSD]) scores, there were few other significant correlations between personality and other clinical variables. Of note, however, treatment responders demonstrated less personality impairment than nonresponders. The finding that personality measures were highly intercorrelated but, on the whole, not well correlated with other clinical measures supports the distinct and dissociable nature of personality phenomena in BDD. Despite the small sample size, these results suggest that personality impairment appears to be significant factor in BDD and may even play a role in treatment response.
