Introduction: Obsessive-compulsive disorder (OCD) is a debilitating psychiatric disorder causing intrusive thoughts or repetitive behaviors. Serotonin reuptake inhibitors are used for OCD treatment, but 40%-60% of patients do not respond to them adequately. In this study, the associations of serotonin receptor 2a polymorphisms rs6311 and rs6313 with OCD, its familial form and fluvoxamine treatment response in Iranian population were investigated. Patients and methods: Association analyses were conducted in 293 OCD cases fulfilling the Diagnostic and Statistical Manual of Mental Disorders (DSM)-IV-TR and 245 controls...

Sceletium tortuosum (Aizoaceae) is widely recognised for the treatment of stress, anxiety and depression, as well as for obsessive compulsive disorders. A comprehensive intraspecies chemotypic variation study, using samples harvested from two distinct regions of South Africa, was done using both proton nuclear magnetic resonance (1 H-NMR) spectroscopy of methanol extracts (N = 145) and ultra performance liquid chromatography-mass spectrometry (UPLC-MS) of acid/base extracts (N = 289). Chemometric analysis of the 1 H-NMR data indicated two main clusters that were region-specific (Northern Cape and Western Cape provinces)...

Gilles de la Tourette syndrome is a chronic and complex tic disorder accompanied by specific behavioral problems in the majority of patients. With its multifaceted interplay between motion and emotion, this condition is a paradigmatic example of the science and art of clinical neuropsychiatry. This review article encompasses the clinical phenomenology of motor and vocal tics and associated sensory experiences (premonitory urges), as well as the behavioral spectrum of the most common comorbidities, including obsessive-compulsive disorder, attention-deficit and hyperactivity disorder, affective symptoms, and impulsivity...

BACKGROUND: Impaired inhibitory control is thought to be a core deficit in psychiatric disorders where patients exhibit problems with controlling urges. These problems include the urge to perform movements typical of Tourette syndrome and the urge to execute compulsive actions typical of obsessive-compulsive disorder. However, the picture emerging from studies that address this issue is controversial. Furthermore, most studies have only focused on reactive control (the ability of subjects to react to a stop signal), but not on proactive control (the ability of patients to shape their response strategies in anticipation of known task demands)...

Heightened experience of disgust is a feature of obsessive-compulsive disorder (OCD), particularly contamination-related OCD (C-OCD). Previous studies of the rubber hand illusion (RHI) reported that the sense of body ownership is related to the interaction between vision, touch, and proprioception. One recent study demonstrated a link between the RHI and disgust, suggesting that there is an interaction between these three perceptual modalities and disgust (Jalal et al., PLOS ONE 10:e0139159, 2015). However, there have been no direct replications of this initial study...

Increased rates of clinically significant internalizing disorders (obsessive compulsive disorder, anxiety, and depression) have been demonstrated in males with Duchenne muscular dystrophy, and a Duchenne muscular dystrophy neuropsychiatric syndrome has been suggested. Although symptoms of depression are widely recognized, some of the other internalizing symptoms are less frequently identified. Through a retrospective chart review of 107 males with Duchenne muscular dystrophy, we identified 15 patients with obsessive compulsive disorder spectrum symptoms; 11 of those also had anxiety symptoms...

The purpose of this study was to determine the specificity and reproducibility of CliniCom™ Psychiatric Assessment Software to appropriately diagnose five prevalent mental health disorders. This online assessment tool incorporates proprietary algorithms for its propensity assessment. Unlike other questionnaires, which require a survey per specific mental disorder, CliniCom can simultaneously assess multiple mental disorders for an individual. CliniCom was concordant with other commonly used assessment tools in diagnosing five prevalent disorders including: Attention Deficit and Hyperactivity Disorder, Generalized Anxiety Disorder, Major Depressive Disorder, Obsessive Compulsive Disorder, and Social Phobia...

The Bergen 4-day concentrated exposure treatment (cET) for obsessive-compulsive disorder (OCD) has proven highly acceptable; with practically no drop-out and a 6 month remission rate of nearly 70%. The aim of the present study was to evaluate long term gains of the approach, and to compare the results to findings from our recent meta-analysis. Sixty-nine of 95 patients consecutively referred to an outpatient clinic in the specialist health care, were offered the Bergen 4-day treatment. Among the 65 who initiated treatment, 60...

The relative health of a field of research can be approximated by assessing peer-reviewed journal publication trends for articles pertinent to that field. The most recent comprehensive assessment of publication trends in the anxiety disorders indicated that the field was on a continuing trajectory of growth (Boschen, 2008). We conducted an updated search of Medline for publications on each of the anxiety disorders from 2006 to 2016. Results indicated that there was continuing growth in anxiety disorders research overall and, particularly, for posttraumatic stress disorder, social anxiety disorder, generalized anxiety disorder, and obsessive compulsive disorder...

BACKGROUND: Disorders of impulsivity are common, functionally impairing, and highly relevant across different clinical and research settings. Few structured clinical interviews for the identification and diagnosis of impulse control disorders exist, and none have been validated in a community sample in terms of psychometric properties. METHODS: The Minnesota Impulse control disorders Interview (MIDI v2.0) was administered to an enriched sample of 293 non-treatment seeking adults aged 18-35 years, recruited using media advertisements in two large US cities...

A 28-year-old male presented with 2 days of vomiting and abdominal pain, preceded by 2 weeks of thirst, polyuria and polydipsia. He had recently started risperidone for obsessive-compulsive disorder. He reported a high dietary sugar intake and had a strong family history of type 2 diabetes mellitus (T2DM). On admission, he was tachycardic, tachypnoeic and drowsy with a Glasgow Coma Scale (GCS) of 10/15. We noted axillary acanthosis nigricans and obesity (BMI 33.2 kg/m2 ). Dipstick urinalysis showed ketonuria and glycosuria...

Frontotemporal dementia (FTD) is the most common form of dementia in the younger age group and often exists with comorbid obsessions and compulsions in up to 80% of the patients. Trichotillomania or compulsive "hair-pulling" disorder is a rare manifestation of FTD and is a poorly evaluated symptom in this condition. The release of "grooming functions" due to frontal disinhibition is often attributed to the evolutionary perspective; however, recent findings also implicate the role of neurotransmitter dysfunction...

Visual stimuli are often used for obsessive-compulsive (OC) symptom provocation in research studies. We tested the induction of anxiety and OC checking symptoms across different types of checking provocation stimuli in three populations: individuals with obsessive compulsive disorder (OCD), individuals with checking symptoms but without a diagnosis of OCD, and control individuals with neither checking symptoms nor a clinical diagnosis. One set of provocative images depicted objects that are commonly associated with checking anxiety...

Background: Specialized inpatient or residential treatment might be an alternative treatment approach for patients with obsessive-compulsive disorder (OCD) that do not respond satisfactorily to the standard outpatient treatment formats. Method: The aim of this open trial was to investigate the 6-month effectiveness of a 3-week inpatient treatment of OCD, where exposure with response prevention (ERP) was the main treatment intervention. The sample consisted of 187 adult patients with OCD, all with previous treatment attempts for OCD...

The cingulum bundle is a prominent white matter tract that interconnects frontal, parietal, and medial temporal sites, while also linking subcortical nuclei to the cingulate gyrus. Despite its apparent continuity, the cingulum's composition continually changes as fibres join and leave the bundle. To help understand its complex structure, this review begins with detailed, comparative descriptions of the multiple connections comprising the cingulum bundle. Next, the impact of cingulum bundle damage in rats, monkeys, and humans is analysed...
