Potential Autoepitope within the Extracellular Region of Contactin-Associated Protein-like 2 in Mice.

Aims: Implicated in autoimmune encephalitis, neuromyotonia and genetic forms of autism, here we report that contactin-associated protein-like 2 (CNTNAP2) contains a potential autoepitope within the extracellular region.

Methodology: CNTNAP2 sequence-similar regions (CSSRs) from human pathogens were identified. Sera from autistic and control children were obtained and analyzed for the presence of antibodies able to bind CSSRs.

Double-blind, placebo-controlled, pilot trial of paliperidone augmentation in serotonin reuptake inhibitor-resistant obsessive-compulsive disorder.

Objective: This pilot study explored the efficacy and tolerability of paliperidone augmentation of serotonin reuptake inhibitors (SRIs) in adults with treatment-resistant obsessive-compulsive disorder (OCD).

Method: Thirty-four patients aged 24-67 years (mean = 43.7 years, SD = 11.

Psychometric properties of the Children's Yale-Brown Obsessive Compulsive Scale in youth with autism spectrum disorders and obsessive-compulsive symptoms.

The psychometric properties of the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS) were investigated in 46 treatment-seeking youth, 7-15 years of age, who were diagnosed with an autism spectrum disorder (ASD) and exhibited obsessive-compulsive symptoms. The CY-BOCS Total score exhibited good internal consistency, with differing internal consistencies observed on the Obsession Severity scale (α = 0.86) and Compulsion Severity scale (α = 0.

The effect of cognitive-behavioral therapy versus treatment as usual for anxiety in children with autism spectrum disorders: a randomized, controlled trial.

Objective: To examine the efficacy of a modular cognitive-behavioral therapy (CBT) protocol relative to treatment as usual (TAU) among children with high-functioning autism spectrum disorders (ASD) and clinically significant anxiety.

Method: A total of 45 children (7-11 years of age) with high-functioning ASD and clinically significant anxiety were randomized to receive 16 sessions of weekly CBT or TAU for an equivalent duration. After screening, assessments were conducted at baseline, post-treatment, and 3-month follow-up.

The role of co-occurring disruptive behavior in the clinical presentation of children and adolescents with anxiety in the context of autism spectrum disorders.

This study explored the impact of disruptive behavior disorder (DBD) comorbidity on theoretically relevant correlates among 87 children and adolescents with autism spectrum disorders (ASD) and clinically significant anxiety. Relative to youth with ASD and anxiety alone, participants with ASD, anxiety, and DBD: (a) presented with significantly more severe anxiety symptoms per clinician-, parent-, and self-report; (b) were more likely to be prescribed antipsychotic medication but were no more likely to receive additional psychosocial and educational interventions; and (c) experienced significantly greater functional impairment and family interference. These results suggest that co-occurring DBD in the context of ASD and anxiety confers greater risk for heightened symptom severity and functional impairment, and may be linked with increased prescription of antipsychotic medication.

Neurocognitive functioning in youth with pediatric autoimmune neuropsychiatric disorders associated with streptococcus.

This study evaluated neurocognitive functioning in 26 youth with Pediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcal infections (PANDAS) and primarily obsessive-compulsive disorder (OCD) symptoms. Marked impairment in visuospatial recall memory (as assessed using the Rey-Osterrieth Complex Figure Test) was observed in spite of average to above-average performance on academic and other neurocognitive measures. Group A beta-hemolytic Streptococcus titer elevations were associated with worse performance on tasks of neurocognitive and executive ability (Stroop Color-Word Interference Test), visuospatial memory, and fine motor speed (finger tapping) as well as elevated obsessive-compulsive symptom severity.

A phenomenological investigation of women with Tourette or other chronic tic disorders.

There are little data concerning clinical characteristics of women with Tourette disorder and chronic tic disorders in the extant literature and what is available mostly focuses on treatment-seeking individuals. The present research was conducted to provide a phenomenological characterization of tic disorders among 185 adult women with tic disorders. In addition to providing a descriptive overview of specific tic symptoms, tic severity, self-reported history of other psychiatric conditions, and impairment/lifestyle impact due to tics, this study compares 185 women and 275 men between 18 and 79 years old with tic disorders (who completed an identical battery of measures) based on demographic, social/economic status indicators, psychiatric variables (comorbidity, family psychiatric history, symptom presentation), adaptive functioning/quality of life, and impairment variables among a nonclinical adult sample.

The role of treatment expectancy in youth receiving exposure-based CBT for obsessive compulsive disorder.

The purpose of this investigation was to examine correlates of parent, child, and therapist treatment expectations and their role in the exposure-based treatment of childhood obsessive compulsive disorder (OCD). Treatment expectations were assessed among 49 youth with primary OCD, their parents, and therapists as part of the baseline evaluation and post-treatment clinical outcomes were determined by blind evaluators. Baseline depressive symptoms, child/parent-rated functional impairment, externalizing behavior problems, number of comorbid psychiatric disorders, and a lower perception of control were associated with lower pre-treatment expectations.

Pediatric autoimmune neuropsychiatric disorders associated with Streptococcus in identical siblings.

Termed pediatric autoimmune neuropsychiatric disorders associated with Streptococcus (PANDAS), these cases of childhood-onset obsessive compulsive disorder and tic disorders resemble the presentation of Sydenham chorea, in that they have an acute onset following a group A beta-hemolytic streptococcal infection (group A Streptococcus), with accompanying neurological signs, and an episodic or sawtooth course. Familial associations of this subgroup of patients remain understudied. This report provides phenotypic descriptions of three youth with PANDAS as well as their genetically identical siblings (in two cases of twins and one case of triplets).

The roles of anxiety and depression in connecting tic severity and functional impairment.

The current study examined relationships between tic severity and both functional impairment and perceived quality of life (QOL) in adults with a chronic tic disorder. The authors explored whether these relationships were moderated by anxiety and depressive symptoms. Five-hundred adults with Tourette's Disorder, Chronic Motor Tic Disorder, or Chronic Vocal Tic Disorder participated in a comprehensive self-report internet-based survey.

Refining clinical judgment of treatment outcome in obsessive-compulsive disorder.

This research aimed to provide clinicians and investigators with optimal treatment outcome criteria for accurately predicting response and remission in both research studies and clinical practice. Data from 153 adult OCD outpatients (ages 18-79) who had participated in a treatment outcome study were examined. Signal detection analysis was conducted to compare levels of Yale-Brown Obsessive Compulsive Scale (Y-BOCS) symptom percent reductions and post treatment absolute scores with Clinical Global Impression (CGI) ratings of symptom improvement and severity.

A preliminary study of D-cycloserine augmentation of cognitive-behavioral therapy in pediatric obsessive-compulsive disorder.

Background: Research on the neural circuitry underlying fear extinction has led to the examination of D-cycloserine (DCS), a partial agonist at the N-methyl-D-aspartate receptor in the amygdala, as a method to enhance exposure therapy outcome. Preliminary results have supported the use of DCS to augment exposure therapy in adult anxiety disorders; however, no data have been reported in any childhood anxiety disorder. Thus, we sought to preliminarily examine whether weight-adjusted DCS doses (25 or 50 mg) enhanced the overall efficacy of cognitive-behavioral therapy (CBT) for pediatric obsessive-compulsive disorder (OCD).

Understudied clinical dimensions in pediatric obsessive compulsive disorder.

The present study aimed to assess the phenomenology and treatment sensitivity of insight, avoidance, indecisiveness, overvalued responsibility, pervasive slowness, and pathological doubting among youth with Obsessive-compulsive disorder (OCD) using the ancillary items on the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS). These factors are believed to be relevant to the clinical presentation of youth with OCD but remain understudied. Eighty-nine youth with OCD were administered the CY-BOCS, including six subsidiary items aimed at the constructs of interest in this research.

Defining treatment response and remission in obsessive-compulsive disorder: a signal detection analysis of the Children's Yale-Brown Obsessive Compulsive Scale.

Objective: To examine the optimal Children's Yale-Brown Obsessive-Compulsive Scale (CY-BOCS) percent reduction cutoffs for predicting treatment response and clinical remission among children and adolescents with obsessive-compulsive disorder (OCD).

Method: Youth with OCD (N = 109; range 7 to 19 years) received 14 sessions of weekly or intensive family-based CBT as part of previously published studies or through the standard clinical flow at our facility. Assessments were conducted before and after treatment and included the CY-BOCS, response and remission status on the Clinical Global Impressions Scale, and the Child Obsessive-Compulsive Impact Scale.

Does cognitive-behavioral therapy response among adults with obsessive-compulsive disorder differ as a function of certain comorbidities?

This study examines the impact of several of the most common comorbid psychiatric disorders (i.e., generalized anxiety disorder (GAD); major depressive disorder (MDD); social phobia, and panic disorder) on cognitive-behavioral therapy (CBT) response in adults with obsessive-compulsive disorder (OCD).

Correlates of insight among youth with obsessive-compulsive disorder.

Background: Individuals with Obsessive-Compulsive Disorder (OCD) may lack insight into the irrational nature of their symptoms. Among adults with OCD, poor insight has been linked to greater symptom severity, increased likelihood of comorbid symptoms, lower adaptive functioning, and worse treatment outcomes. Parallel work regarding insight among children and adolescents, with OCD, is lacking.
