BACKGROUND: Obsessive-compulsive disorder (OCD) is a heterogeneous neuropsychiatric condition, thought to have a significant genetic component. When onset occurs in childhood, affected individuals generally exhibit different characteristics from adult-onset OCD, including higher prevalence in males and increased heritability. Since neuropsychiatric conditions are associated with copy number variations (CNVs), we considered their potential role in the etiology of OCD. METHODS: We genotyped 307 unrelated pediatric probands with idiopathic OCD (including 174 that were part of complete parent-child trios) and compared their genotypes with those of 3861 population controls, to identify rare CNVs (<0...

There is a high rate of comorbidity between obsessive-compulsive disorder (OCD) and autism spectrum disorders (ASD). Standard cognitive-behavior therapy (CBT) protocols have been shown to be less effective in treating OCD in young people with ASD than in typically developing youth. This case study describes the treatment of an adolescent boy with severe, treatment-resistant OCD and ASD using a modified CBT approach. Modifications to a standard evidence-based CBT for OCD protocol included extended psychoeducation about anxiety; regular home-based sessions; and increased involvement of systems, including family and school...

OBJECTIVE: The tic-related subtype of obsessive-compulsive disorder (OCD) has a distinct clinical profile. The course of tic-related OCD has previously been investigated in treatment studies, with inconclusive results. This study aimed to compare clinical profiles between tic-related and tic-free OCD patients and to establish the influence of tics on the 2-year natural course in adult OCD patients. METHODS: Within the Netherlands OCD Association cohort, 377 patients with a current DSM-IV diagnosis of OCD were divided into a tic-related group (28%) and a tic-free group and compared on clinical variables with t tests or χ² tests...

We describe a case study of comorbid obsessive-compulsive disorder (OCD) in a nine-year-old boy with Duchenne muscular dystrophy (DMD). Patient history included persistent deficits in social communication and restrictive and repetitive patterns of behavior: a diagnosis of autism spectrum was formalized. Due to serious disruption on social functioning and negative development of the obsessive behavior we decided to start pharmacotherapy. Fluoxetine 5 mg/day was started and gradually increased to 20 mg/day...

Recent studies have strongly implicated postsynaptic scaffolding proteins such as SAPAP3 or Shank3 in the pathogenesis of various mood disorders, including autism spectrum disorder, bipolar disorder (BD), and obsessive-compulsive disorders. Neural Abelson-related gene-binding protein 2 (nArgBP2) was originally identified as a protein that interacts with SAPAP3 and Shank3. Recent study shows that the genetic deletion of nArgBP2 in mice leads to manic/bipolar-like behavior resembling symptoms of BD. However, the function of nArgBP2 at synapse, or its connection with the synaptic dysfunctions, is completely unknown...

Aripiprazole is a partial dopamine agonist with only minor neurological and psychiatric adverse effects, making it a potential first-line drug for the treatment of psychiatric disorders. However, the evidence of its use in children and adolescents is rather sparse. The aim of this case study is to discuss adverse drug reaction (ADR) reports concerning aripiprazole-associated neurological and psychiatric events in children and adolescents. The ADR report database at Danish Medicines Agency was searched for all ADRs involving children and adolescents (<18 years) reported by the search term [aripiprazole] AND all spontaneous reports since the introduction of aripiprazole in 2003 until December 31, 2015...

A new application for omega-3 fatty acids has recently emerged, concerning the treatment of several mental disorders. This indication is supported by data of neurobiological research, as highly unsaturated fatty acids (HUFAs) are highly concentrated in neural phospholipids and are important components of the neuronal cell membrane. They modulate the mechanisms of brain cell signaling, including the dopaminergic and serotonergic pathways. The aim of this review is to provide a complete and updated account of the empirical evidence of the efficacy and safety that are currently available for omega-3 fatty acids in the treatment of psychiatric disorders...

Eating disorders have been defined as "characterized by persistence disturbance of eating or eating-related behavior that results in the altered consumption or absorption of food and that significantly impairs health or psychosocial functioning". The psychopathology of eating disorders changed across time under the influence of environmental factors, determining the emergence of new phenotypes. Some of these conditions are still under investigation and are not clearly identified as independent diagnostic entities...

Impulsivity and compulsivity have emerged as important dimensional constructs that challenge traditional psychiatric classification systems. Both are present in normal healthy populations where the need to act quickly and repeatedly without hesitation can be highly advantageous. However, when excessively expressed, impulsive and compulsive behavior can lead to adverse consequences and spectrum disorders exemplified by attention-deficit/hyperactivity disorder (ADHD), obsessive compulsive disorder (OCD), autism, and drug addiction...

Repetitive transcranial magnetic stimulation (rTMS) is a treatment option with proved effectiveness especially in drug resist depression. It is used in functional brain mapping before neurosurgery operations and diagnostic of corticospinal tract transmission. Many studies are performed to evaluate rTMS using in treatment of obsessive - compulsive disorder, schizophrenia, autism, strokes, tinnitus, Alzheimer and Parkinson diseases, cranial traumas. Moreover rTMS was used in treatment of multiple sclerosis, migraine, dystonia...

We examined co-occurrence of autism spectrum disorder (ASD) with (traits of) attention-deficit/hyperactivity (ADHD), obsessive-compulsive (OCD) and inhibition deficits in a community sample (n = 16,676) and tested whether having a sibling with ASD manifested in increased features of ADHD, OCD or inhibition deficits. Individuals with ASD had increased ADHD and OCD traits compared with individuals without ASD. Individuals with a sibling with ASD exhibited more ADHD traits than did individuals whose sibling did not have ASD...

BACKGROUND: The Autism-Spectrum Quotient (AQ) is widely used to quantify autistic traits, which have been evaluated in the parents of individuals with autism spectrum disorders (ASD) and in the general population. This paper's objective was to investigate the AQ's psychometric properties of the Chinese version for mainland China and to establish whether the pattern of sex differences in the quantity of autistic traits exists. We also examined the usefulness of the AQ in differentiating between individuals with ASD, schizophrenia (SCH), obsessive-compulsive disorder (OCD) and healthy controls (HC)...

Social cooperation is defined as a joint action for mutual benefit that depends on the individual and the counterparts' behaviors. To gain valid evidence for social cooperation behavior we conducted a series of experiments in our suggested fully automated non-conditioned maze and depicted three major findings: (i) During 18 days of training the rats showed a progressive social learning curve as well as latent social learning; (ii) Examining the perceptual communication between the cooperating partners, we found a correlation between the available perceptual modalities and the social cooperation performance; and (iii) Investigating contextual learning as a competing process to the social cooperation, we found that additional contextual cues impaired the social cooperation performance...

Tourette syndrome (TS) is more than having motor and vocal tics, and this review will examine the varied comorbidities as well as the social impact and quality of life (QoL) in individuals with TS. The relationship between any individual and his/her environment is complex, and this is further exaggerated in the case of a person with TS. For example, tics may play a significant role in shaping the person's experiences, perceptions, and interactions with the environment. Furthermore, associated clinical features, comorbidities, and coexisting psychopathologies may compound or alter this relationship...

OBJECTIVE: Neurodevelopmental disorders (NDDs) (attention deficit hyperactivity disorder [ADHD], autism spectrum disorder [ASD], and obsessive-compulsive disorder [OCD]) share genetic vulnerability and symptom domains. The authors present direct comparison of structural brain circuitry in children and adolescents with NDDs and control subjects and examine brain circuit-behavior relationships across NDDs using dimensional measures related to each disorder. METHOD: Diffusion imaging and behavioral measures were acquired in 200 children and adolescents (ADHD: N=31; OCD: N=36; ASD: N=71; controls: N=62; mean age range: 10...

Many psychiatric and behavioral disorders manifest in childhood (attention deficit hyperactivity disorder, obsessive compulsive disorder, anxiety, depression, schizophrenia, autism spectrum disorder, etc.) and the opportunity for intervening early may attenuate full development of the disorder and lessen long term disability. Yet, pediatric drug approvals for CNS indications are limited, and pediatric testing generally occurs only after establishing adult efficacy, more as an afterthought rather than with the initial goal of developing the medication for a pediatric CNS indication...

Prosaccade and antisaccade errors in the context of social and nonsocial stimuli were investigated in youth with autism spectrum disorder (ASD; n = 19) a matched control sample (n = 19), and a small sample of youth with obsessive compulsive disorder (n = 9). Groups did not differ in error rates in the prosaccade condition for any stimulus category. In the antisaccade condition, the ASD group demonstrated more errors than the control group for nonsocial stimuli related to circumscribed interests, but not for other nonsocial stimuli or for social stimuli...

Glycine acts as an inhibitory neurotransmitter at glycine receptor (GlyR)-enriched synapses and as an obligatory co-agonist at the N-methyl-D-aspartate (NMDA) receptor, where it facilitates neuronal excitation. Two high-affinity and substrate selective transporters, glycine transporter-1 and glycine transporter-2 (GlyT-1 and GlyT-2), regulate extracellular glycine concentrations within the CNS and as such, play critical roles in maintaining a balance between inhibitory and excitatory neurotransmission. GlyT-1 inhibition has been extensively examined as a potential means by which to treat several CNS disorders that include schizophrenia, depression, anxiety, obsessive compulsive disorder (OCD), and addiction...
