The current study examined the mechanisms of attention allocation in adult ADHD to investigate the frequently reported diminished target processing in ADHD as well as the less consistently observed increased distractibility by task-irrelevant distracting stimuli. To this end, while high-density EEG was recorded, 25 adults with ADHD and 23 healthy controls completed a 4-stimulus oddball task that comprised a frequently presented standard stimulus and 3 different categories of equally infrequent stimuli: task-relevant targets, task-irrelevant nontargets, and task-irrelevant unfamiliar novels...

Attention deficit with, or without, hyperactivity and impulsivity (ADHD) is categorized as neuro-developmental disorder. ADHD is a common disorder in childhood and one of the most frequent conditions affecting school ages. This disorder is characterized by a persistent behavioral pattern associated with inattention, over-activity (or hyperactivity), and difficulty in controlling impulses. Current research suggests the existence of certain patterns of cortical activation and executive control, which could more objectively identify ADHD...

Individual differences in the propensity for left versus right frontal electroencephalogram (EEG) asymmetry may underlie differences in approach/withdrawal tendencies and mental health deficits. Growing evidence suggests that early life adversity may shape brain development and contribute to the emergence of mental health problems. The present study examined frontal EEG asymmetry (FEA) following the transition to family care in children adopted internationally from institutional care settings between 15 and 36 months of age (N = 82; 46 female, 36 male)...

Neurofeedback is increasingly recognized as an intervention to treat core symptoms of attention deficit hyperactivity disorder (ADHD). Despite the large number of studies having been carried out to evaluate its effectiveness, it is widely elusive what neuronal mechanisms related to the core symptoms of ADHD are modulated by neurofeedback. 19 children with ADHD undergoing 8 weeks of theta/beta neurofeedback and 17 waiting list controls performed a Go/Nogo task in a pre-post design. We used neurophysiological measures combining high-density EEG recording with source localization analyses using sLORETA...

OBJECTIVE: A controversial issue is whether self-report of symptoms and impairment is sufficient for diagnosis of attention-deficit/hyperactivity disorder (ADHD) in adolescents and adults in the absence of other informants, such as parents. The present study investigated how well self-report is reflected by cognitive-neurophysiological and actigraph measures, which we have previously shown to discriminate between ADHD persisters, remitters and controls using parent-report (Cheung et al...

While attention-deficit/hyperactivity disorder (ADHD) and bipolar disorder (BD) denote distinct psychiatric conditions, diagnostic delineation is impeded by considerable symptomatic overlap. Direct comparisons across ADHD and BD on neurophysiological measures are limited. They could inform us on impairments that are specific to or shared between the disorders and, therefore, potential biomarkers that may aid in the identification of the diagnostic boundaries. Our aim was to test whether quantitative EEG (QEEG) identifies differences or similarities between women with ADHD and women with BD during resting-state and task conditions...

OBJECTIVE: Psychostimulant medications are the gold standard of treatment for attention-deficit/hyperactivity disorder (ADHD); however, a significant minority (∼30%) of individuals with ADHD fail to respond favorably. Noradrenergic agents are increasingly used as ADHD monotherapies or adjuncts for suboptimal stimulant response, yet knowledge of their cortical effects is limited. This study is the first to examine comparative effects of guanfacine (an α adrenergic 2A agonist), psychostimulant, and their combination on resting state cortical activity in ADHD...

This study aims to explore the differences of event-related potential (ERP) between attention deficit hyperactivity disorder (ADHD) and normal children, so that these differences provide scientific basis for the diagnosis of ADHD. Eight children were identified to be ADHD group by the diagnostic criteria of DSM-IV (diagnostic and statistical manual of mental disorders-IV), and the control group also consisted of 8 normal children. Modified visual-continuous performance test (CPT) was used as the experiment paradigm...

The DIRAS2 gene is coding for a small Ras GTPase with so far unknown function. In a previous study we described the association of DIRAS2 rs1412005 as well as a haplotype containing this polymorphism and located in the promoter region of this gene with Attention-deficit/hyperactivity disorder (ADHD). In the present study, we searched for rare variants within or near the DIRAS2 gene that might be associated with ADHD using next generation sequencing. As we were not able to detect any rare variants associated with the disease, we sought to establish a functional role of DIRAS2 rs1412005 on the molecular or systems level...

INTRODUCTION: ADHD occurs in 3% of school-age children (and in 70% of them in adulthood) and represents an important medical and social problem. It is characterized by attention deficits, hyperactivity and impulsiveness. Neurofeedback therapy (EEG biofeedback, NF) is carried out based on the analysis of EEG. OBJECTIVE: To investigate the effect of NF therapy on clinical status and parameters of the EEG in ADHD. MATERIALS AND METHODS: In the years 2007-2014, 287 children (191 boys), aged 6-17 years were included into the study...

Problemgambling is thought to be comorbid with attention-deficit hyperactivity disorder (ADHD). We tested whether gamblers and ADHD patients exhibit similar reward-related brain activity in response to feedback in a gambling task. A series of brain electrical responses can be observed in the electroencephalogram (EEG) and the stimulus-locked event-related potentials (ERP), when participants in a gambling task are given feedback regardless of winning or losing the previous bet. Here, we used a simplified computerized version of the Iowa Gambling Task (IGT) to assess differences in reinforcement-driven choice adaptation between unmedicated ADHD patients with or without problem gambling traits and contrasted with a sex- and age-matched control group...

Attention deficit hyperactivity disorder (ADHD) is associated with deficits in motor learning and sleep. In healthy adults, overnight improvements in motor skills are associated with sleep spindle activity in the sleep electroencephalogram (EEG). This association is poorly characterized in children, particularly in pediatric ADHD. Polysomnographic sleep was monitored in 7 children with ADHD and 14 typically developing controls. All children were trained on a validated motor sequence task (MST) in the evening with retesting the following morning...

BACKGROUND AND METHODS: We present the preliminary results of a prospective case-control sleep study in children with a diagnosis of attention-deficit hyperactivity disorder (ADHD). A deep sleep assessment including sleep questionnaires, sleep habits, a video-polysomnographic recording with full high-density electroencephalography (EEG) and cardiorespiratory polygraphy, multiple sleep latency test, and 1-week actigraphic recording were performed to verify whether children with ADHD may be classified into one of the following five phenotypes: (1) hypoarousal state, resembling narcolepsy, which may be considered a "primary" form of ADHD; (2) delayed sleep onset insomnia; (3) sleep-disordered breathing; (4) restless legs syndrome and/or periodic limb movements; and (5) sleep epilepsy and/or EEG interictal epileptiform discharges...

Research has documented reciprocal influences between approach-related and inhibition-related neural activity in adults. However, associations between neural systems of approach and inhibition have not been tested in children. It is thus unclear whether these links are present early in life and whether associations between neural systems of approach and inhibition have long-term behavioral consequences. To address these gaps in the literature, we used electroencephalography (EEG) to examine associations between approach-related neural activity (i...

Neuropsychiatric EEG-Based ADHD Assessment Aid (NEBA) is an EEG-based device designed to aid in the diagnostic process for ADHD by identifying individuals less likely to have ADHD by virtue of a lower theta/beta ratio. In using NEBA as an example, the Arns et al. commentary misstates the purpose of NEBA, which is to widen the differential rather than to make the diagnosis. Arns et al. caution about missing an ADHD diagnosis, but fail to mention the impact of overdiagnosis. If we are to advance our knowledge of the etiology and pathophysiology of ADHD, as well as develop tailored treatments and ultimately improve outcomes for ADHD, then biomarkers and objective assessment aids such as NEBA are needed to improve and refine diagnostic accuracy beyond symptom description and clinical history...
