Sibley, Coxe, and Molina provide a thoughtful discussion of the implications of our study and highlight important future directions in this line of work. They helpfully amplify several themes that space did not allow discussion of in our article. In particular, they correctly emphasize the importance of theoretical as well as statistical considerations in model selection. We also agree that clinical tests of sensitivity and specificity, taking into account different base rates and types of samples, are essential before a final algorithm would be ready for dissemination...

INTRODUCTION: Attention-deficit/hyperactivity disorder (ADHD) is a major public health issue. Pharmacological treatments play an important role in the multimodal treatment of ADHD. Currently, there is a lack of up-to-date and comprehensive evidence on how available ADHD drugs compare and rank in terms of efficacy and tolerability, in children or adolescents as well as in adults. We will conduct a network meta-analysis (NMA), integrating direct and indirect comparisons from randomised controlled trials (RCTs), to rank pharmacological treatments for ADHD according to their efficacy and tolerability profiles...

INTRODUCTION: A number of previous studies examined a possible association of toxic metals and autism, and over half of those studies suggest that toxic metal levels are different in individuals with Autism Spectrum Disorders (ASD). Additionally, several studies found that those levels correlate with the severity of ASD. METHODS: In order to further investigate these points, this paper performs the most detailed statistical analysis to date of a data set in this field...

BACKGROUND: A previous small study suggested that Brain Network Activation (BNA), a novel ERP-based brain network analysis, may have diagnostic utility in attention deficit hyperactivity disorder (ADHD). In this study we examined the diagnostic capability of a new advanced version of the BNA methodology on a larger population of adults with and without ADHD. METHOD: Subjects were unmedicated right-handed 18- to 55-year-old adults of both sexes with and without a DSM-IV diagnosis of ADHD...

Reports of sleep disturbances in attention deficit hyperactivity disorder (ADHD) are common in both children and adults; however, the aetiology of such disturbances is poorly understood. One potentially important mechanism which may be implicated in disrupted sleep in ADHD is the circadian CLOCK, a known key regulator of the sleep/wake cycle. In this systematic review, we analyse the evidence for circadian rhythm changes associated with ADHD, as well as assessing evidence for therapeutic approaches involving the circadian CLOCK in ADHD...

The cognitive profile differences between adult patients with autism spectrum disorder (ASD) and those with attention-deficit/hyperactivity disorder (ADHD) are not well characterized. We examined the cognitive profiles of adults having either ASD (n=120) or ADHD (n=76) with no intellectual disabilities (IQ≥70) using the Wechsler Intelligence Scale III (WAIS-III). Verbal Intelligence (VIQ) - Performance Intelligence (PIQ) difference discrepancies were detected between the two groups. Information subtest scores of the Verbal Comprehension index and Arithmetic and Digit Span subtests of the Freedom from Distractibility index were significantly higher in ASD than in ADHD, while the Picture Completion subtest was significantly lower in ASD...

A previous study (Upadhyaya et al. in Eur J Psychiatry 2013b; 27:185-205) reported that adults with attention-deficit/hyperactivity disorder (ADHD) demonstrated maintenance of response for up to 25 weeks after initially responding to atomoxetine treatment. In the present report, the consistency of treatment effect across three geographic regions (Europe, United States/Canada [US/Can], and Latin America [Latin Am]) was explored. Data were analyzed from a phase 3, multicenter, randomized, double-blind, maintenance-of-response (randomized withdrawal) trial of atomoxetine versus placebo in adults with ADHD...

Cyclin-dependent kinase 5 (CDK5) is a multifaceted protein shown to play important roles in the central nervous system. Abundant evidence indicates that CDK5 hyperactivities associated with neuronal apoptosis and death following ischemic stroke. CDK5 activity increases when its cofactor p35 cleaves into p25 during ischemia. Theoretically, inhibition of CDK5/p25 activity or reduction of p25 would be neuroprotective. TFP5, a modified 24-aa peptide (Lys254-Ala277) derived from p35, was found to effectively inhibit CDK5 hyperactivity and improve the outcomes of Alzheimer's disease and Parkinson's disease in vivo...

Glucocorticoid hormones (GCs) released from the fetal/maternal glands during late gestation are required for normal development of mammalian organs and tissues. Accordingly, synthetic glucocorticoids have proven to be invaluable in perinatal medicine where they are widely used to accelerate fetal lung maturation when there is risk of pre-term birth and to promote infant survival. However, clinical and pre-clinical studies have demonstrated that inappropriate exposure of the developing brain to elevated levels of GCs, either as a result of clinical over-use or after stress-induced activation of the fetal/maternal adrenal cortex, is linked with significant effects on brain structure, neurological function and behaviour in later life...

Why are boys at risk? To address this question, I use the perspective of regulation theory to offer a model of the deeper psychoneurobiological mechanisms that underlie the vulnerability of the developing male. The central thesis of this work dictates that significant gender differences are seen between male and female social and emotional functions in the earliest stages of development, and that these result from not only differences in sex hormones and social experiences but also in rates of male and female brain maturation, specifically in the early developing right brain...

BACKGROUND: Tourette syndrome (TS) is a childhood-onset disorder characterized by motor and vocal tics. While cognitive features of common comorbid conditions such as attention deficit hyperactive disorder and obsessive compulsive disorder have been widely investigated, the cognitive profile of TS patients remains to be precisely defined. In this regard, the executive functions system (EF) is of especial interest. AIMS: The aim of the study was to delineate the various components of executive processes in adult TS patients...

Youth and adults with Attention-Deficit/Hyperactivity Disorder (ADHD) experience academic and social impairment and engage in risky behaviors. Emotion dysregulation (ED) is associated with ADHD and may contribute to these impairments and behaviors. Although many measures of ED exist, little is known about the physiological bases of ED, in the context of ADHD. In a large sample of children (M age = 9.01 years; 62% male) with (n = 48) and without (n = 56) ADHD, we examined (1) the correspondence between parent-reported ED and heart rate variability (HRV) - a psychophysiological marker of parasympathetic engagement and (2) whether parent-reported ED is predicted by HRV above and beyond ADHD...

REVIEW
Suzanna Becker
The generation of new neurons in the adult mammalian brain has led to numerous theories as to their functional significance. One of the most widely held views is that adult neurogenesis promotes pattern separation, a process by which overlapping patterns of neural activation are mapped to less overlapping representations. While a large body of evidence supports a role for neurogenesis in high interference memory tasks, it does not support the proposed function of neurogenesis in mediating pattern separation...

In order to understand links that exist between inherited risk or predisposition, brain and behavioural development, endocrine regulation and social/environmental stimuli, animal models are crucial. The Wistar-Kyoto (WKY) rat has been shown to have validity as a model of adult and adolescent depression. While sex- and age-specific differences in some of the face, predictive and construct validities of the model such as depression-like behaviours have been established, anhedonia and anxiety using other induced anxiety paradigms such as elevated plus maze remain equivocal...

The Weiss Functional Impairment Rating Scale Self-Report has been translated into nine languages and has been widely used in assessing functional impairment of adults with ADHD. This study is a psychometric validation of the WFIRS-S in Japanese. The WFIRS-S-J and other questionnaires were administered to 46 adults with attention-deficit-hyperactivity disorder (ADHD), 104 control adults, and 889 university students. ADHD diagnoses were made using the Japanese semi-structured diagnostic interview for adult ADHD, which is compatible with the DSM-5...

Status epilepticus (SE) in rats, along with chronic epilepsy, leads to the development of behavioral impairments resembling depressive disorder and/or attention deficit/hyperactivity disorder (ADHD), thus reflecting respective comorbidities in epilepsy patients. Suppressed neurotransmitter tone in the raphe nucleus (RN)-prefrontal cortex (PFC) serotonergic pathway and in the locus coeruleus (LC)-PFC noradrenergic pathway underlies depressive- and impulsive-like behavioral deficits respectively. We examined possible mechanisms leading to the monoamine dysfunction in brainstem efferents, namely modulatory effects of the neuropeptide galanin on serotonin (5-HT) and norepinephrine (NE) signaling...

The main purpose of this study was to examine whether adult patients with attention deficit hyperactivity disorder (ADHD) demonstrate sets of dysfunctional cognitive beliefs and behavioural tendencies according to Jeffrey Young's schema-focused therapy model. Sets of dysfunctional beliefs (maladaptive schemas) were assessed with the Young Schema Questionnaire (YSQ-S2) in 78 adult ADHD patients and 80 control subjects. Patients with ADHD scored significantly higher than the control group on almost all maladaptive schemas...

There is considerable variation in practice, both between and with different countries in the management of attention deficit hyperactivity disorder (ADHD). Whilst there is no one optimal model of service organisation there are general principles of care that can be introduced to reduce this variability. There are frequent debates and discussions about which professional group is best placed to manage ADHD at different points in the life cycle. Who delivers care is however less important than ensuring that training schemes provide adequate exposure, training and experience to both the core and non-core skills required to provide a comprehensive package of care...
