It is known that children with mental and developmental problems are at risk of abuse and neglect. Attention-deficit/hyperactivity disorder is one of the most frequent neurodevelopmental disorders in children and adolescents. The purpose of this study is to examine whether children diagnosed with ADHD are under more risk in terms of child abuse and neglect compared to controls. In this case-control study, 104 children, who applied to Child and Adolescent Psychiatry Unit of Bursa Yuksek Ihtisas Training and Research Hospital between January and June 2015, were diagnosed with ADHD, and had no other psychiatric comorbidity except for disruptive behavior disorders, and 104 healthy children were compared...

Altered serotonergic neurotransmission has been found to cause impulsive and aggressive behavior, as well as increased motor activity, all exemplifying key symptoms of ADHD. The main objectives of this positron emission tomography (PET) study were to investigate the serotonin transporter binding potential (SERT BPND ) in patients with ADHD and to assess associations of SERT BPND between the brain regions. 25 medication-free patients with ADHD (age ± SD; 32.39 ± 10.15;10 females) without any psychiatric comorbidity and 25 age and sex matched healthy control subjects (33...

An enhanced ability to detect visual targets amongst distractors, known as visual search (VS), has often been documented in Autism Spectrum Disorders (ASD). Yet, it is unclear when this behaviour emerges in development and if it is specific to ASD. We followed up infants at high and low familial risk for ASD to investigate how early VS abilities links to later ASD diagnosis, the potential underlying mechanisms of this association and the specificity of superior VS to ASD. Clinical diagnosis of ASD as well as dimensional measures of ASD, attention-deficit/hyperactivity disorder (ADHD) and anxiety symptoms were ascertained at 3 years...

Attention deficit hyperactivity disorder (ADHD) is a common disorder, often associated with sleep disorders. Patients with primary sleep disorders often present hyperactivity and/or attention deficit symptoms. Indeed, obstructive sleep disorder breathing (snoring, hypoventilation disorder, and obstructive sleep apnea syndrome) with poor sleep quality can mimic ADHD in children. In this case, inattention and hyperactivity behavior are induced by sleep disorders but do not constitute a clinical diagnosis of ADHD...

BACKGROUND: Numerous factor analytic studies consistently support a distinction between two symptom domains of attention-deficit/hyperactivity disorder (ADHD), inattention and hyperactivity/impulsivity. Both dimensions show high internal consistency and moderate to strong correlations with each other. However, it is not clear what drives this strong correlation. The aim of this paper is to address this issue. METHOD: We applied a sophisticated approach for causal discovery on three independent data sets of scores of the two ADHD dimensions in NeuroIMAGE (total N = 675), ADHD-200 (N = 245), and IMpACT (N = 164), assessed by different raters and instruments, and further used information on gender or a genetic risk haplotype...

Excessive calorie intake constitutes a global public health concern, due to its associated range of untoward outcomes. Gambling is commonplace and gambling disorder is now considered a behavioral addiction in DSM-5. The relationships between calorie intake, gambling, and other types of putatively addictive and impulsive behaviors have received virtually no research attention. Two-hundred twenty-five young adults who gamble were recruited from two Mid-Western university communities in the United States using media advertisements...

OBJECTIVES: Few studies have examined sluggish cognitive tempo (SCT) in college students even though extant research suggests a higher prevalence rate of SCT symptoms in this population compared to general adult or youth samples. The current study examined SCT symptoms in relation to two domains related to college student's academic success, study skills and daily life executive functioning (EF), as well as specific domains of functional impairment. METHOD: 158 undergraduate students (Mage = 19...

Importance: Recent reports have demonstrated a higher incidence of autism spectrum disorder (ASD) and substantially elevated autistic trait burden in individuals with neurofibromatosis type 1 (NF1). However, important discrepancies regarding the distribution of autistic traits, sex predominance, and association between ASD symptoms and attentional problems have emerged, and critical features of the ASD phenotype within NF1 have never been adequately explored. Establishing NF1 as a monogenic cause for ASD has important implications for affected patients and for future research focused on establishing convergent pathogenic mechanisms relevant to the potential treatment targets for ASD...

OBJECTIVE: Both bipolar spectrum disorders (BPSD) and attention deficit hyperactivity disorder (ADHD) present with emotion-regulation deficits, but require different clinical management. We examined how the neurobiological underpinnings of emotion regulation might differentiate youth with BPSD versus ADHD (and healthy controls, HCs), specifically assessing functional connectivity (FxC) of amygdala-prefrontal circuitry during an implicit emotion processing task. METHODS: We scanned a subset of the Longitudinal Assessment of Manic Symptoms (LAMS) sample, a clinically recruited cohort with elevated behavioral and emotional dysregulation, and age/sex-ratio matched HCs...

Attention-deficit/hyperactivity disorder (ADHD) is a highly heritable childhood-onset neuropsychiatric condition, often persisting into adulthood. The genetic architecture of ADHD, particularly in adults, is largely unknown. We performed an exome-wide scan of adult ADHD using the Illumina Human Exome Bead Chip, which interrogates over 250 000 common and rare variants. Participants were recruited by the International Multicenter persistent ADHD CollaboraTion (IMpACT). Statistical analyses were divided into 3 steps: (1) gene-level analysis of rare variants (minor allele frequency (MAF)<1%); (2) single marker association tests of common variants (MAF⩾1%), with replication of the top signals; and (3) pathway analyses...

The present study examined mediators and moderators of the relation between parental ADHD symptomatology and the development of child attention-deficit/hyperactivity disorder (ADHD) and oppositional defiant disorder (ODD) symptoms across the preschool years. Participants included 258 (138 boys) 3-year-old children (M = 44.13 months, SD = 3.39) with and without behavior problems and their parents who took part in a 3-year longitudinal study. Maternal ADHD symptoms predicted later ADHD symptoms in children, controlling for early child symptomatology...

Deficits in error-processing are postulated in core symptoms of ADHD. Our goal was to investigate the neurophysiological basis of abnormal error-processing and adaptive adjustments in ADHD, and examine whether error-related alterations extend beyond traditional Regions of Interest (ROIs), particularly to those involved in adaptive adjustments, such as the Salience Network system. We obtained event-related potentials (ERPs) during a Go/NoGo task from 22 adult-ADHD patients and 29 matched healthy controls using a high-density 256-electrode array...
