OBJECTIVE: Research has implicated glutamatergic projections between the various frontal subregions in the pathogenesis of compulsivity and impulsivity. Reducing striatal glutamate release, or antagonising the action of glutamate at its receptors, may therefore represent viable treatment strategies. Several glutamatergic agents with regulatory approval for other indications are available and may be of potential benefit in the treatment of compulsivity/impulsivity in psychiatric disorders in paediatric patients...

Psychological and psychiatric dysfunction is a major problem in a substantial proportion of young adults with Down syndrome. Some patients develop psychiatric issues, such as depressive, obsessive-compulsive, or psychotic-like disorders, in their late adolescence or young adulthood. Furthermore, these individuals may experience moderate to severe emotional and psychological distress. Development of a psychosocial treatment to address these issues is needed in addition to psychotropic medication. The current study reports two cases of young adults with Down syndrome, who presented psychiatric symptoms and marked disruption in their daily lives...

OBJECTIVE: Pediatric Acute Neuropsychiatric Syndrome (PANS) and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS) are conditions marked by sudden onset of obsessive-compulsive disorder (OCD), tics, or avoidant/restrictive food intake in combination with multiple psychiatric symptoms. A diagnosis of PANS or PANDAS may be supported by the Cunningham Panel, a commercially available set of immunologic assays currently in clinical use. However, the relationship between Cunningham Panel results and patient symptoms remains unclear...

OBJECTIVES: Executive network deficits are putative neurocognitive endophenotypes for obsessive-compulsive disorder (OCD). Yet, unlike alterations in fronto-striatal and limbic connectivity, connectivity in the fronto-parietal (FPN) and cingulo-opercular (CON) networks involved in cognitive control has received little attention. METHODS: The coherence of FPN, CON and fronto-limbic networks was investigated in 39 unmedicated OCD patients, 16 of their unaffected siblings and 36 healthy controls using resting-state functional-connectivity MRI and a seed-based analysis approach...

Archival data were used to examine the feasibility of a 5-day, clinic-based, intensive exposure-based cognitive-behavioral group therapy for childhood anxiety disorders (CADs) and obsessive-compulsive disorder (OCD). Participants were 143 children (82 girls) aged 6 to 19 years ( M = 13.93 years, SD = 2.9 years) with CADs or OCD (or both) in 28 consecutive groups. Repeated-measures ANOVA in the subsample ( n = 57) with complete treatment data indicated positive change on all variables from pretreatment to posttreatment with few differences between CADs and OCD patients...

Excoriation (skin-picking) disorder (SPD) shares symptomology with other obsessive-compulsive and related disorders. Few studies, however, have examined the neurological profile of patients with SPD. This study examined differences in cortical thickness and basal ganglia structural volumes between 20 individuals with SPD and 16 healthy controls using magnetic resonance imaging (MRI). There were no significant differences in demographic variables (age, gender, education and race) between groups. All subjects completed a structural MRI scan and completed a battery of clinical assessments focusing on SPD symptom severity, depression and anxiety symptoms, and quality of life...

There is ample evidence that obsessive-compulsive disorder (OCD) is based on reduced serotonergic function. Replicated bidirectional selection for thermoregulatory nest-building behavior in the laboratory house mouse (Mus musculus) resulted in compulsive-like, non-compulsive-like and randomly bred control mice that represent a non-induced animal model of OCD. The present study aimed at investigating the neurochemical patterns in specific brain regions of compulsive-like (HA) versus non-compulsive-like (LA) and normal (CA) mice...

The oxytocin receptor (OXTR) is a potential candidate in the pathophysiology of obsessive-compulsive disorder (OCD). The present study investigated the association between common single-nucleotide polymorphism (SNPs) of the OXTR gene and the affected status of OCD or distinct clinical subtypes of OCD including the age at onset and symptom dimensions. Ten SNPs of OXTR were examined in 615 patients with OCD and 581 healthy controls. Single-marker and haplotype-based association analyses were conducted. While OXTR variants were not associated with the affected status of OCD or its clinical symptom dimensions, rs2268493 (p=0...

Background: Motor abnormalities (MAs) of severe mental disorders have been traditionally neglected both in clinical practice and research, although they are an increasing focus of attention because of their clinical and neurobiological relevance. For historical reasons, most of the literature on MAs has been focused to a great extent on schizophrenia, and as a consequence their prevalence and featural properties in other psychiatric or neuropsychiatric disorders are poorly known. In this article, we evaluated the extent to which catatonic, extrapyramidal and neurological soft signs, and their associated clinical features, are present transdiagnostically...

BACKGROUND: Family accommodation is associated with a range of clinical features including symptom severity, functional impairment, and treatment response. However, most previous studies in children and adolescents investigated family accommodation in samples of youth with obsessive-compulsive disorder (OCD) or anxiety disorders receiving non-intensive outpatient services. AIMS: In this study, we aimed to investigate family accommodation of anxiety symptoms in a sample of youth with clinical anxiety levels undergoing an intensive multimodal intervention for anxiety disorders or OCD...

Disruption of oxidant/anti-oxidant ratio as well as endoplasmic reticulum (ER) stress are thought to be involved in the pathophysiology of schizophrenia. These stresses can lead to impairments in brain functions progressively leading to neuronal inflammation followed by neuronal cell death. Moreover, the cellular stresses are interlinked leading us to the conclusion that protein misfolding, oxidative stress and apoptosis are intricately intertwined events requiring further research into their mechanistic and physiological pathways...

PURPOSE: To prospectively examine whether higher daily hassles predict a variety of incident mental disorders and respective associations vary by gender, age, perceived coping efficacy and number of negative life events. METHODS: Data comes from the Early Developmental Stages of Psychopathology Study (EDSP), a prospective-longitudinal study among adolescents and young adults from the community (n = 2797, aged 14-24 at baseline) followed up in up to 3 assessment waves over 10 years...

Repetitive and perseverative behaviors are common features of a number of neuropsychiatric diseases such as Angelman's syndrome, Tourette's syndrome, obsessive-compulsive disorder, and autism spectrum disorders. The oxytocin system has been linked to the regulation of repetitive behavior in both animal models and humans, but many of its downstream targets have still to be found. We report that the melanin-concentrating hormone (MCH) system is a target of the oxytocin system in regulating one repetitive behavior, marble burying...

BACKGROUND: Obsessive-compulsive disorder (OCD) is a condition which can have major effects on the life of both the sufferer and their family members. Previous research has shown that the impact of illness on family members is related to their conceptualisation of the illness. In the present study we used qualitative methods to explore illness perceptions in family members of people with OCD. METHOD: Fourteen family members of people meeting diagnostic criteria for OCD within the previous year took part in a semi-structured interview...
