Schizophrenia is a neurodevelopmental disorder characterized by abnormal processing of information and attentional deficits. Schizophrenia has a high genetic component but is precipitated by environmental factors, as proposed by the 'two-hit' theory of schizophrenia. Here we compared latent inhibition as a measure of learning and attention, in CHL1-deficient mice, an animal model of schizophrenia, and their wild-type littermates, under no-stress and chronic mild stress conditions. All unstressed mice as well as the stressed wild-type mice showed latent inhibition...

OBJECTIVE: Tourette's disorder (TD) and autism spectrum disorder (ASD) share clinical features and possibly an overlapping etiology. The aims of this study were to examine ASD symptom rates in participants with TD, and to characterize the relationships between ASD symptom patterns and TD, obsessive-compulsive disorder (OCD), and attention-deficit/hyperactivity disorder (ADHD). METHOD: Participants with TD (n = 535) and their family members (n =234) recruited for genetic studies reported TD, OCD, and ADHD symptoms and completed the Social Responsiveness Scale Second Edition (SRS), which was used to characterize ASD symptoms...

OBJECTIVE: Methylphenidate has prominent effects in the dopamine-rich striatum that are absent for the selective norepinephrine transporter inhibitor atomoxetine. This study tested whether baseline striatal activation would predict differential response to the two medications in youth with attention-deficit/hyperactivity disorder (ADHD). METHOD: A total of 36 youth with ADHD performed a Go/No-Go test during functional magnetic resonance imaging at baseline and were treated with methylphenidate and atomoxetine using a randomized cross-over design...

OBJECTIVE: Prior studies have established that attention-deficit/hyperactivity disorder (ADHD) is associated with risky sexual behavior, but it remains unknown whether individuals with ADHD also are more likely to become parents while being teenagers. This aspect is clinically relevant because teenage parenthood is associated with adverse outcomes for parents and children. Therefore, the main aim of this study was to investigate whether individuals with ADHD would be more likely to become teenage parents compared with individuals without ADHD...

The purpose of the present study was to examine the impact of the Incredible Years® Teacher Classroom Management (IY TCM) training on teacher perceptions of parental involvement. A cluster randomized design was used to assign 42 classroom teachers to either an IY TCM training (n=19) or a control condition (n=23). Teachers rated parental involvement (i.e., bonding with teacher, parental involvement at school) for the families of 805 low income students (IY TCM=504, control=301). A latent profile transition analysis framework was used to model the effect of IY TCM on teacher perceptions of parental involvement from pre to posttest...

BACKGROUND: Emotional lability (EL) is an associated feature of attention-deficit/hyperactivity disorder (ADHD) in adults, contributing to functional impairment. Yet the effect of pharmacological treatments for ADHD on EL symptoms is unknown. We conducted a systematic review and meta-analysis to examine the effects of stimulants and atomoxetine on symptoms of EL and compare these with the effects on core ADHD symptoms. METHODS: A systematic search was conducted on the databases Embase, PsychInfo, and Ovid Medline(®) and the clinicaltrials...

Fetal Alcohol Spectrum Disorders encompass a wide range of birth defects in children born to mothers who consumed alcohol during pregnancy. Typical mental impairments in FASD include difficulties in life adaptation and learning and memory, deficits in attention, visuospatial skills, language and speech disabilities, mood disorders and motor disabilities. Multimodal imaging methods have enabled in vivo studies of the teratogenic effects of alcohol on the central nervous system, giving more insight into the FASD phenotype...

Study Objectives: REM sleep behavior disorder (RBD) is a parasomnia affecting 33 to 46% of patients with Parkinson's disease (PD). The existence of a unique and specific impaired cognitive profile in PD patients with RBD is still controversial. We extensively assessed cognitive functions to identify whether RBD is associated with more severe cognitive deficits in nondemented patients with PD. Methods: One hundred and sixty-two participants, including 53 PD patients with RBD, 40 PD patients without RBD, and 69 healthy subjects, underwent polysomnography, a neurological assessment, and an extensive neuropsychological exam to assess attention, executive functions, episodic learning and memory, visuospatial abilities, and language...

Substance use disorders (SUD) are one of the most frequent mental disorders among adults. Attention-Deficit/Hyperactivity-Disorder (ADHD) is one of the most common mental health issues in childhood and adolescence, often persisting in adulthood. ADHD in childhood and adolescence is a robust predictor of tobacco, alcohol and illicit substance use in adulthood. Prevalence of comorbid ADHD in SUD patients is high. Nearly one quarter of these patients fulfill the DSM IV criteria for ADHD. Integrated concepts for treatment of SUD and ADHD are needed, but rare up to now...

Pathological gambling (PG) is a common and costly public health problem associated with impaired quality of life and high suicide rates. Despite its frequency in the general population, PG course is poorly understood in older adults who are especially vulnerable to its devastating consequences. We enrolled 175 subjects in a longitudinal study of gambling behavior: our case group of 53 older adults with PG (≥ 60 years), and two comparison groups including 72 younger adults with PG (< 40 years) and 50 older adults without PG (≥ 60 years)...

Apart from the typical motor symptoms, Parkinson's disease is characterized by a wide range of different non-motor symptoms, which are highly prevalent in all stages of the disease and have an incisive influence on quality of life. Moreover, their treatment continues to be challenging. In this review, we critically summarize the evidence for the impact of dopaminergic therapies on non-motor symptoms in Parkinson's disease. We performed a PubMed search to identify relevant clinical studies that investigated the response of non-motor symptoms to dopaminergic therapy...

BACKGROUND: This study examined mental health outcomes in extremely preterm children (EPT) born at 23 to 25 weeks of gestation between 1992 and 1998 at 2 Swedish tertiary care centers that offered regional and active perinatal care to all live-born EPT infants. METHODS: We assessed 132 (98%) of the 134 EPT survivors at 10 to 15 years of age alongside term-born controls. Behavioral and emotional problems were evaluated by using Achenbach's Child Behavior Checklist and Teacher Report Form and Conners' Parent and Teacher scales for attention-deficit/hyperactivity disorder...

The cannabinoid-1 receptor (CB1R) agonist Δ9-tetrahydrocannabinol (THC), the main psychoactive constituent of cannabis, adversely effects working memory performance in humans. The α2A-adrenoceptor (AR) agonist guanfacine improves working memory performance in humans. The authors aimed to determine the effects of short-term (6 days) treatment with guanfacine on adverse cognitive effects produced by THC. Employing a double-blind, placebo-controlled crossover design, the cognitive, subjective, and cardiovascular effects produced by oral THC (20 mg) administration were determined twice in the same cannabis users: once after treatment with placebo and once after treatment with guanfacine (3 mg/day)...

Relatively little attention has been given paternal effects on next generation. Given that Bisphenol A (BPA), a ubiquitous compound in maternal diet, may disrupt brain development and behavior, we hypothesized that paternal BPA diet (PBD) could affect offspring development. Prefrontal cortex (PFC), a vital brain region, is involved in emotion and social behavior. To test whether PBD could alter developing PFC, we carried out a proteomics approach for PFC in male juvenile offspring that responded to PBD (50 mg BPA/kg diet)...

OBJECTIVE: Methylphenidate activates μ-opioid receptors, which are linked to euphoria. μ-Opioid antagonists, such as naltrexone, may attenuate the euphoric effects of stimulants, thereby minimizing their abuse potential. This study assessed whether the combination of naltrexone with methylphenidate is well-tolerated while preserving the clinical benefits of stimulants in subjects with attention-deficit/hyperactivity disorder (ADHD). METHODS: We conducted a 6-week, double-blind, placebo-controlled, randomized clinical trial of naltrexone in adults with DSM-IV ADHD receiving open treatment with a long-acting formulation of methylphenidate from January 2013 to July 2015...

OBJECTIVE: The past decades have seen a surge in stimulant prescriptions for the treatment of attention-deficit/hyperactivity disorder (ADHD). Stimulants acutely alleviate symptoms and cognitive deficits associated with ADHD by modulating striatal dopamine neurotransmission and induce therapeutic changes in brain activation patterns. Long-term functional changes after treatment are unknown, as long-term studies are scarce and have focused on brain structure. In this observational study (2009-2012), we investigated associations between lifetime stimulant treatment history and neural activity during reward processing...
