Attention deficit hyperactivity disorder (ADHD) is a childhood-onset neurodevelopmental disorder with a prevalence of 1·4-3·0%. It is more common in boys than girls. Comorbidity with childhood-onset neurodevelopmental disorders and psychiatric disorders is substantial. ADHD is highly heritable and multifactorial; multiple genes and non-inherited factors contribute to the disorder. Prenatal and perinatal factors have been implicated as risks, but definite causes remain unknown. Most guidelines recommend a stepwise approach to treatment, beginning with non-drug interventions and then moving to pharmacological treatment in those most severely affected. Randomised controlled trials show short-term benefits of stimulant medication and atomoxetine. Meta-analyses of blinded trials of non-drug treatments have not yet proven the efficacy of such interventions. Longitudinal studies of ADHD show heightened risk of multiple mental health and social difficulties as well as premature mortality in adult life. PMID:26386541

Attention-deficit hyperactivity disorder (ADHD) is a challenging condition to diagnose and treat. For diagnosis, the clinician needs to establish the presence of ADHD on Diagnostic and Statistical Manual of Mental Disorders criteria requiring information from parents and teachers and considering both alternative diagnoses and co-occurring conditions. In the treatment of ADHD as a chronic illness, the clinician needs to educate the family about the condition and partner with them about treatment decisions. The 2 treatments with demonstrated efficacy for ADHD are medications (stimulant medications and a selective norepinephrine reuptake inhibiter) and behavior-modification programs. PMID:17178358

In this chapter we have reviewed the diagnosis and management of attention deficit disorder, focusing particularly on the role of stimulant therapy in ADHD. Hisorical review suggests that ADHD has roots that extend back almost a century. The definition of ADHD is based on inclusion and exclusion criteria that are established by history and reflect behavioral concerns. Attention-deficit/hyperactivity disorder is a chronic disorder affecting the child's home, school, and community life. The primary symptoms of the disorder manifest a developmental pattern: activity diminishes while attentional deficits persist. Major sources of concern are the secondary and often more resistant problems of learning difficulties, behavioral problems, lack of peer acceptance, and low self-esteem. An often frustrating and perplexing characteristic of the disorder is its marked variability-over time, across situations, and within the same child and similar situations. Educational management represents an important priority and often forms the cornerstone of all other therapies, nonpharmacologic or pharmacologic. Cognitive-behavioral therapies represent the most widely used alternative to pharmacotherapy. Although the effects of CBT alone are disappointing, recent studies suggest that such therapies may provide a useful adjunct to pharmacotherapy and may be helpful when children are tapered off medication. Psychotherapy, or a combination of psychotherapy and medication (termed multimodality therapy), may also be useful. Pharmacotherapy for ADHD originated almost 60 years ago, and at this time the ameliorative effects of medications in ADHD are well established. The general skepticism of experienced clinicians, coupled with a climate where parents are reluctant to medicare children, serves to limit their use except where indicated. Although the effects of stimulants on attention and activity seem well established, effects on cognition, conduct, and social behavior are more controversial

Full Text Available Attention Deficit Hyperactivity Disorder is one of the most common developmental disorders of childhood with a reported world-wide prevalence of 8 to 12 %. In studies conducted in our country the prevalence rates in community were reported to vary between 8.6 to 8.1 % while clinical prevalence rates were reported to vary between 8.6 to 29.44 %. Fifty to eighty percent of cases were reported to continue into adolescence while thirty to fifty percent may continue into adulthood. Attention deficit hyperactivity disorder is known to accompany subtle physical anomalies, allergic and neurologic disorders, obesity and eating disorders, traumatic injuries, risky sexual behavior, sleep disorders, substance and alcohol use, axis I and II disorders, occupational, legal and academic problems and increased treatment expenditures. Though the effects of this disorder continue throughout life, create burdens to the society along with its treatment as well as disabling the affected patients through their lives, and receive increasing attention in recent years, reviews focusing on problems associated with it are lacking. Therefore, this study aimed to summarize the results of previous studies conducted about medical comorbidities in attention deficit hyperactivity disorder.
Pharmacotherapy, one of the effective modalities of treatment for attention deficit/hyperactivity disorder (ADHD), was discovered serendipitously and, until recently, consisted primarily of short-acting methylphenidate and dextroamphetamine compounds. The US Food and Drug Administration's (FDA) approval of Concerta in 2000 followed by approval of additional long-acting methylphenidate (Ritalin LA; Metadate CD) and amphetamine formulations (Adderall XR) expanded the repertoire. By providing su...

Full Text Available Attention-deficit hyperactivity disorder (ADHD/ADD is a neurobehavioral disorder of childhood onset characterized by severe, developmentally inappropriate motor hyperactivity, inattention, and impulsiveness that result in impairment in more than one setting. It affects the home, school, and community life of 39% of school-going children worldwide. There is increasing recognition that ADHD symptoms and clinically defined disorder can persist into adult life and are associated with later drug and alcohol misuse and social and work difficulties. Added to that is the extreme variability of the disorder over time, within the same individual, between individuals, and across different circumstances. Treatment with stimulants and nonstimulants has proven effective in different subgroups, with the effectiveness of specific agents most likely related to the primary neurotransmitter involved. However, stimulants with a short duration of action have been problematic for some patients. Parent training and cognitive behavioral therapies represent the most widely adjunct psychosocial interventions to pharmacotherapy.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder with a long-term impact on functioning,productivity and quality of life of patients.This impact is largely due to the symptoms of inattentiveness.However,despite its impairing role in the lives of ADHD patients,inattentiveness has been studied relatively less frequently than have symptoms of impulsivity/hyperactivity and problems with executive function.This review therefore seeks to integrate the neuropsychological theories and current findings in the research fields of neuropsychology,neurophysiology,and neuroimaging,in an attempt to gain a more complete understanding of the role that inattentiveness plays in ADHD,as well as to suggest directions for future studies.The need for a more comprehensive understanding of inattentiveness and ADHD,which integrates findings from each of the three disciplines mentioned above,is emphasized.

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children, adolescents, and adults, with a prevalence estimated from 5% to 7% across cultures and approximately 2% to 5% in adults. This lifelong disorder challenges nurses to understand the basis of ADHD, analyze symptoms, differentiate coexisting disorders, gather health information from varied sources, and implement person-centered multimodal treatment. Nurses are poised to plan, and work with patients, families, and teachers in the community and school systems to optimize academic and occupational performance and improve quality of life. Pharmacotherapy, psychoeducation, and behavioral therapies are strong components of multimodal treatment planning. PMID:27229276

Attention deficit hyperactivity disorder (ADHD) manifests by high levels of inattention, impulsiveness and hyperactivity. ADHD starts in childhood and results in impairments that continue into adulthood. While hyperactivity declines over time, inattention and executive function difficulties persist, leading to functional deficits. Adolescents and adults with ADHD have pervasive impairment in interpersonal and family relationships. They may develop addiction, delinquent behavior and comorbid psychiatric disorders. Despite advances in diagnosis and treatment, persistent residual symptoms are common, highlighting the need for novel treatment strategies. Mindfulness training, derived from Eastern meditation practices, may improve self-regulation of attention. It may also be a useful strategy to augment standard ADHD treatments and may be used as a potential tool to reduce impairments in patients with residual symptoms of ADHD. Clinically, this would manifest by an increased ability to suppress task-unrelated thoughts and distractions resulting in improved attention, completion of tasks and potential improvement in occupational and social function.

Full Text Available Attention Deficit Hyperactivity Disorder (ADHD is one of the most common neuropsychiatric disorders of childhood. Due to studies reporting that the effects of ADHD diagnosis on functioning may last throughout life, this disorder, which has great importance for child and adolescent psychiatry, started to attract greater attention recently in terms of adult psychiatry. A review, evaluating the results of studies conducted on the genetic basis of ADHD, which started to attract increasing attention both in our country and the world, was thought to help clinicians working in this field. PubMed and Turkish Psychiatry Index online search engines were screened using “attention deficit hyperactivity disorder”, “ADHD”, “genetics” as key words. The data obtained were combined with information gleaned from several textbooks. Based on previous studies, it could easily be concluded that ADHD is one of the most common heritable psychiatric disorder with distinguished genetic features. Despite its importance for diagnosis and treatment, the etiology of ADHD is still not clear and the disorder seems to be a complex problem arising from the effects of both genetic and environmental factors. Although previous studies revealed that ADHD displayed familial and hereditary transmission, stable patterns of Mendelian inheritance could not be discriminated by evaluation of pedigrees. Therefore, many studies have been conducted on the molecular genetic basis of ADHD recently. The previous studies did not report consistent results in identification of the genes responsible for ADHD which has been partially linked to heterogeneity of the disorder. Grouping relevant patients according to comorbidities and persistence in adolescence rather than DSM-IV subtypes could be an important alternative method for overcoming this limitation in the research studies.

In recent years, there is an increasing awareness that individuals may purposely feign or exaggerate symptoms of attention deficit hyperactivity disorder (ADHD) to gain external incentives, including access to stimulant drugs or special academic accommodations. There are vast consequences of undetected feigned ADHD such as substantial costs covered by society for unnecessary assessments and treatments, unjustified occupation of limited medical resources and undermining society's trust in the existence of the disorder or the effectiveness of treatment. In times of economic crisis and cost savings in the medical sector, the detection of feigned ADHD is of importance. This review briefly describes the research on this topic with an emphasis on the approaches available for detection of feigned ADHD (i.e., self-report questionnaires, personality inventories, cognitive tests used in routine neuropsychological assessment and tests specifically designed for detecting feigned cognitive dysfunction). Promising approaches and measures are available for identifying feigned ADHD but there is an immediate need for further research. PMID:25096370
The proposed revision of the diagnostic criteria in DSM-5 for attention-deficit/hyperactivity disorder (ADHD) will not fundamentally change the concept of ADHD. This is mainly due to the fact that, DSM-5 will retain the exact DSM-IV wording of all 18 symptoms, but will add new examples that make...... changes will most likely increase the prevalence of ADHD, especially in adults and adolescents, but maybe also in children. The added examples will also result in necessary revisions and new validations of rating scales and diagnostic interviews.

Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral developmental disorder in children and adults characterized by a persistent pattern of impulsiveness, inattention and hyperactivity. It affects about 3-10% of children and 2-5% of adolescents and adults and occurs about four times more commonly in boys than girls. The cause of ADHD is unknown, but it has strong genetic and environment components. The first-line treatment options for ADHD include behavioral therapy, pharmacotherapy with stimulants or both. Methylphenidate and amphetamine salts are the stimulant drugs of choice for ADHD treatment. Amphetamines act by increasing presynaptic release of dopamine and other biogenic amines in the brain. Methylphenidate inhibits the reuptake of dopamine and norepinephrine and therefore its pharmacology is identical to that of amphetamines. Lisdex-amfetamine is a prodrug of dextroamphetamine with low feasibility for abuse. Atomoxetine, a selective norepinephrine reuptake inhibitor, is an alternative, non-stimulant drug for ADHD but it is less efficacious than stimulants. Stimulants are generally safe but are associated with adverse effects including headache, insomnia, anorexia and weight loss. There is increased awareness about serious cardiovascular and psychiatric adverse events with ADHD drugs including concern for growth suppression in children. Stimulants have a high potential for abuse and dependence, and should be handled safely to prevent misuse and abuse. PMID:24191257

Full Text Available Attention deficit hyperactivity disorder (ADHD is a serious problem to pediatric neurologists. The prevalence of ADHD in developed countries ranges from 1 to 20 %. ADHD is characterized by a triad of symptoms: inattention, hyperactivity, and impulsivity (the International Statistical Classification of Diseases, 10th revision, codes it as F90 and it is the most common conduct disorder in children. The etiology of ADHD remains disсutable to the present day; there are a few basic concepts of the origin of this disorder. Its manifestations may be a reason for family conflicts, poor peer relationships, social and school maladjustment, learning problems, lower academic performance, accidents and injuries, smoking, psychoactive substance abuse (toxicomania, narcomania, delinquencies, deviant social behavior, thus having a negative impact on all spheres of a patient’s life. The manifestations of ADHD may continue in adulthood, resulting in work and family life problems, low self-evaluation, alcohol and psychoactive substance abuse, and other unfavorable consequences. The authors describe the etiology, pathogenesis, diagnostic principles (diagnostic scales and tests, differential diagnosis (by setting out a large group of different diseases, the manifestations of which can mimic ADHD, treatment, and prognosis of the disorder. Within its therapeutic correction framework, the authors present the definition and general principles of Montessori therapy, including recommendations for parents and relatives to deal with children with ADHD.
Full Text Available Abstract Background Attention Deficit/Hyperactivity Disorder (ADHD, formerly regarded as a typical childhood disorder, is now known as a developmental disorder persisting over the lifespan. Starting in preschool-age, symptoms vary depending on the age group affected. Method According to the variability of ADHD-symptoms and the heterogeneity of comorbid psychiatric disorders, a broad review of recent studies was performed. These findings were summarized in a developmental psychopathological model, documenting relevant facts on a timeline. Results Based on a genetic disposition and a neuropsychological deregulation, there is evidence for factors which persist across the lifespan, change age-dependently, or show validity in a specific developmental phase. Qualitative changes can be found for children in preschool-age and adults. Conclusion These differences have implications for clinical practice as they can be used for prevention, diagnostic proceedings, and therapeutic intervention as well as for planning future studies. The present article is a translated and modified version of the German article "Entwicklungspsychopathologie der ADHS", published in Zeitschrift für Psychiatrie, Psychologie und Psychotherapie, 56, 2008, S. 265-274.
Full Text Available Attention Deficit Hyperactivity Disorder (ADHD continues to be controversial with arguments for and against its veracity being waged by individuals representing a variety of disciplines from behavioral scientists to philosophers. Our perspective focuses on the epistemological underpinnings of what is now commonly known as ADHD. Its ignominious history and current disputes may stem from a "pessimistic" epistemology, meaning that truth is only the province of persons in authority and power. The authoritative organizations that govern the diagnostic labels and criteria are the American Psychiatric Association and their Diagnostic and Statistical Manual and the World Health Organization that sponsors the International Classification of Disease. We contrast the pessimistic epistemology with criteria for truth from the scientific method. Although scientific scrutiny has been and is being applied subsequent to "authoritarian edicts" of the disorder, we opine that ADHD currently does not have status beyond that of the "hypothetical construct." Moreover, current brain-based causal models have failed to provide rigorous supporting data that comes from testing falsifiable hypotheses.
Overton, Paul G
Attention deficit hyperactivity disorder (ADHD) is a prevalent neurodevelopmental disorder characterised by (inter alia) an increase in distractibility. The current front-line pharmacotherapies for the treatment of ADHD, namely the psychostimulants methylphenidate and amphetamines, have clear abuse potential, hence there is a strong need to develop new drug treatments for this disorder. Central to this process is the identification of the pathophysiological changes which underlie ADHD. Given the heterogeneity of the disorder, multiple loci are probably involved, providing multiple potential therapeutic targets. Here, we hypothesise (Hypothesis 1) that one such locus is the superior colliculus (SC), a sensory structure intimately linked with distractibility and the production of eye and head movements. It is proposed that in ADHD, the colliculus is hyper-responsive, leading to the core symptom of increased distractibility. Hypothesis 1 is supported by: 1. ADHD patients show increased distractibility in tasks which are sensitive to collicular function; 2. ADHD patients have a general problem inhibiting saccades, the generation of which involves the SC; 3. Saccadic deficits in ADHD include defects in the production of saccadic types (anti-saccades and express saccades) which are particularly associated with the colliculus; 4. Covert shifts in attention (which also have been argued to involve the SC) are also impaired in ADHD; 5. Reading disorders are frequently co-morbid with ADHD; dyslexia (which is associated with eye movement problems) is linked to a specific visual perceptual deficit in the M pathway, a major recipient of which is the colliculus. Whether or not the SC is indeed hyper-responsive in ADHD as Hypothesis 1 suggests, the SC may well represent an important therapeutic target for drugs. In fact current psychostimulant therapies, which reduce distractibility, may already work at that level (Hypothesis 2), a contention which is supported by: 1. The
Attention-deficit disorder (attention-deficit/hyperactivity disorder without hyperactivity): A neurobiologically and behaviorally distinct disorder from attention-deficit/hyperactivity disorder (with hyperactivity)
Most studies of attention-deficit/hyperactivity disorder (ADHD) have focused on the combined type and emphasized a core problem in response inhibition. It is proposed here that the core problem in the truly inattentive type of ADHD (not simply the subthreshold combined type) is in working memory. It is further proposed that laboratory measures, such as complex-span and dual-task dichotic listening tasks, can detect this. Children with the truly inattentive type of ADHD, rather than being dist...

Attention deficit hyperactivity disorder (ADHD) is characterised by impulsivity, hyperactivity and inattention. Up to 5% of primary school age children have ADHD. Both genes and environment play a role in the aetiology of ADHD. If left untreated, children with ADHD demonstrate a range of poor long-term psychosocial outcomes. The Strengths and Difficulties Questionnaire (SDQ) may be used to screen children for a range of psychiatric disorders, including ADHD.1

Schizophrenia and attention deficit hyperactivity disorder (ADHD) are two psychiatric disorders with a negative impact on quality of life of individuals affected. Although they are classified into distinct disorders categories, attentional dysfunction is considered as a core feature in both conditions, either at the clinical then pathophysiological level. Beyond the obvious clinical overlap between these disorders, the Research Domain Criteria approach might offer an interesting perspective for disentangling common circuits underpinning both disorders. Hence, we review evidences regarding the overlap between schizophrenia and ADHD, at the clinical level, and at the level of underlying brain mechanisms. The evidence regarding the influence of environmental risk factors in the emergence of both disorders, and their developmental trajectories is also reviewed. Among these, we will try to elucidate the complex relationship between stimulants use and psychotic symptoms, discussing the potential role of ADHD medication in inducing psychosis or in exacerbating it. We aim that, taken together, these findings may promote further investigation with important implications both for clinicians and research. In fact, considering the amounting evidence on the overlap between schizophrenia and ADHD, the delineation of their boundaries might help in the decision for diagnosis and treatment. Moreover, it may help to promote interventions focused on the prevention of both schizophrenia and ADHD, by the reduction of recognized environmental risk factors. PMID:25815254

Full Text Available Despite high rates of reported comorbidity in patients with social anxiety disorder, attention deficit hyperactivity disorder comorbidity was not evaluated in these studies. Studies, investigating the prevalence of adult attention deficit hyperactivity disorder (ADHD comorbidity in social anxiety disorder are limited and little is known about it. The reason for this may be the fact that, ADHD have been seen as a childhood disease over a period of time. In the prospective studies ,it is reported that ADHD is often observed in the adulthood and effects persist . On the other hand, studies on attention deficit hyperactivity disorder, higher rates of social anxiety disorder comorbidity have been reported. The presence of comorbid anxiety disorder increases the risk of impulsive feature in ADHD, causes problems in functionality, impaired compliance and resistance to the treatment. The aim of this article is to investigate the the status of social anxiety disorder and ADHD comorbidity and to discuss the hypothesis of antidepressant-associated hypomanic shift due to antidepressant treatment in social anxiety disorder patients.

Attention deficit/hyperactivity disorder (ADHD) in children has been associated with attentional and executive problems, but also with socioemotional difficulties possibly associated with deficits in Theory of Mind (ToM). Socioemotional problems in ADHD are associated with more negative prognoses, notably interpersonal, educational problems, and an increased risk of developing other psychiatric disorders that emphasize the need to clarify the nature of their ToM deficits. In this study, we hypothesized that ToM dysfunction in children with ADHD is largely attributable to their attentional and/or executive deficits. Thirty-one children with ADHD (8-12 years, IQ > 85) and 31 typically developing (TD) children were assessed using executive functions (inhibition, planning, and flexibility) and attentional tasks, as well as two advanced ToM tasks (Reading the Mind in the Eyes and Faux Pas) involving different levels of executive control. Children with ADHD performed more poorly than TD children in attentional, executive function, and ToM tasks. Linear regression analyses conducted in the ADHD group indicated that inhibition scores predicted performance on the "Faux Pas" task the best, while attention scores were the best for predicting performance on the Reading the Mind in the Eyes task. When controlled for inhibition and attentional variables, ToM performance in children with ADHD was actually similar to TD children. Contrarily, controlling for ToM scores did not normalize performance for inhibition and attentional tasks in children with ADHD. This unidirectional relationship suggests that deficits in the EF and attentional domains are responsible for ToM deficits in ADHD, which therefore may contribute to their socioemotional difficulties.

Full Text Available This study aimed to investigate if an executive functions (EF intervention could promote these skills in individuals with attention deficit and hyperactivity disorder (ADHD. Eighteen children and adolescents, 7-13 years old, divided into experimental (EG, N = 8 and control (CG, N = 10 groups, were assessed in the Block Design and Vocabulary subtests of the WISC III and seven tests of EF. Parents answered two scales, measuring EF and inattention and hyperactivity signs. EG children participated in a program to promote EF in twice-weekly group sessions of one hour each. After 8 months of intervention, groups were assessed again. ANCOVA, controlling for age, intelligence quotient and pretest performance, revealed gains in attention/inhibition and auditory working memory measures for the EG. No effect was found for scales or measures of more complex EF. Results are not conclusive, but they illustrate some promising data about EF interventions in children and adolescents with ADHD.

Full Text Available Attention deficit hyperactivity disorder is a developmental disorder with an age onset prior to 7 years. Children with ADHD have significantly lower ability to focus and sustain attention and also score higher on impulsivity and hyperactivity. Stimulants, such as methylphenidate, have remained the mainstay of ADHD treatment for decades with evidence supporting their use. However, recent years have seen emergence of newer drugs and drug delivery systems, like osmotic release oral systems and transdermal patches, to mention a few. The use of nonstimulant drugs like atomoxetine and various other drugs, such as a-agonists, and a few antidepressants, being used in an off-label manner, have added to the pharmacotherapy of ADHD. This review discusses current trends in drug therapy of ADHD and highlights the promise pharmacogenomics may hold in the future.

The attention-deficit hyperactivity disorder (ADHD) is one of the most common disorders in childhood and adolescence with a prevalence of app. 5%. The importance of ADHD in childhood as a factor of vulnerability for psychiatric disorders in adults is becoming a focus of discussion. It was shown that there is a comorbidity in adults with substance abuse, delinquency and personality disorders. There is a growing evidence that ADHD will persist in a significant number of patients during adulthood. This is the first german study to evaluate this interdependence. We examined 164 adult inpatients and 48 healthy volunteers with the Wender Utah Rating Scale (WURS), a retrospective self-evaluation scale for the diagnosis of ADHD in childhood, and the Eysenck impulsiveness questionnaire I7. It could be shown that the WURS and the I7 are suitable instruments for the evaluation of the ADHD in adults especially concerning the aspects of attention deficits and impulsiveness. PMID:10087514

This article provides a brief overview of the major psychosocial treatments that have some efficacy for the management of attention-deficit/hyperactivity disorder (ADHD) in children. Parent training in effective child behavior management methods, classroom behavior modification methods and academic interventions, and special educational placement appear to have the greatest promise of efficacy. Augmenting these, additional family therapy in problem-solving and communication skills and the coordination of multiple school resources across the day may be necessary. To be effective in improving prognosis, treatments must be maintained over extended periods of time. PMID:12562060

Attention-deficit/hyperactivity disorder (ADHD) is the most common reason for referral to child and adolescent psychiatry clinics. Although stimulant medications represent an evidence-based approach to managing ADHD, psychosocial interventions for child/adolescent ADHD target functional impairments as the intervention goal, and rely heavily on behavioral therapy techniques and operant conditioning principles. Evidence-based psychosocial interventions for managing pediatric ADHD include behavioral parent training, school-based interventions relying on behavioral modification, teaching skills, and operant conditioning principles, and intensive summer treatment programs. The use of conjoint psychosocial treatments with ADHD medications may enable lower doses of each form of treatment. PMID:25455577

Adults with attention deficit hyperactivity disorder (ADHD) show attentional dysfunction such as distractibility and mind-wandering, especially in lengthy tasks. However, fundamentals of dysfunction are ambiguous and relationships of neuropsychological test parameters with self-report measures of ADHD symptoms are marginal. We hypothesize that basic deficits in sustaining attention explain more complex attentional dysfunction in persons with ADHD and relate to ADHD symptoms. Attentional function was analyzed by computing ex-Gaussian parameters for 3 time Blocks in a 20 min test of sustained alertness. Changes in performance across these blocks were analyzed by comparing adult persons with ADHD (n = 24) with healthy matched controls (n = 24) and correlated with neuropsychological measures of selective and divided attention as well as self-report measures of ADHD symptoms. We found a significantly steeper increase in the number of slow responses (ex-Gaussian parameter τ) in persons with ADHD with time on task in basic sustained alertness. They also performed significantly worse in tasks of sustained selective and divided attention. However, after controlling for an increase in τ during the alertness task, significant differences between groups disappeared for divided and partly selective attention. Increases in τ in the sustained alertness task correlated significantly with self-report measures of ADHD symptoms. Our results provide evidence that very basic deficits in sustaining attention in adults with ADHD are related to infrequent slow responses (=attentional lapses), with changes over time being relevant for more complex attentional function and experienced ADHD symptoms in everyday life.

Full Text Available Attention-deficit-hyperactivity disorder (ADHD is a common neuro-behavioural disorder with onset in childhood. These children have impaired emotional self-control, self-regulation of drive and motivation. Numerous studies have reported cognitive disabilities in memory, executive functions, spatial abilities and language skills. The main objective of this work is to determine whether a socio-emotional intervention programme could improve executive functions in children with Attention Deficit Hyperactivity Disorder. The sample of this study consisted of 25 children (8 female and 17 male aged between 8 and 12 years, diagnosed with ADHD and who were not taking any psychopharmacological treatment at the time of the study, and had not taken medication previously. Executive functioning was assessed through the Zoo Map test and Tower of Hanoi puzzle in pre-/post-test design. A socio-emotional intervention programme was implemented. The training consisted of 8 one-hour weekly sessions, on an individual basis. Results indicate that such a programme does lead to improved performance in the execution of tasks that evaluate executive functions. After the intervention, the children took less time to resolve the Zoo Map test. Results for the Hanoi Tower puzzle were also improved after intervention. The children needed a lower number of movements to complete the task.
Attention Deficit Hyperactivity Disorder (ADHD) is a neurobiological disorder of early childhood onset. Defining symptoms are chronic impairments of attention, impulse control and motor hyperactivity that frequently persist until adulthood. Miscellaneous causes of the disorder have been discussed. Accumulating evidence from imaging- and molecular genetic studies strengthened the theory of ADHS being a predominantly inherited disorder of neurobiological origin. In the last 15 years, non-invasive brain imaging methods were successfully implemented in pediatric research. Functional magnetic resonance imaging studies gave major insight into the neurobiological correlates of executive malfunction, inhibitory deficits and psychomotoric soft signs. These findings are in good accordance with brain morphometric data indicating a significant volumetric decrease of major components of striato-thalamo-cortical feedback loops, primarily influencing prefrontal executive functioning (e.g. basal ganglia). Empirical evidence points to a broad array of associated behavioral disturbances like deficient visuomotor abilities and oculomotor dysfunctions. This paper reviews the current empirical evidence derived from prior imaging studies. Special emphasis is given to the relevance of oculomotor dysfunctions in clinical and research settings, as well as their assessment in the MR environment. (orig.)

Tricyclic antidepressants have well-demonstrated efficacy in treating behavioral symptoms, but desipramine should be avoided, at least in youths and adolescents (and perhaps adults), because safer tricyclics are available. Bupropion was effective in its few controlled trials, but tics and (especially in youth) skin rash limit its value. Venlafaxine appears effective, but controlled studies are needed. Serotonin selective reuptake inhibitors have not been tested in controlled trials, but they cause inconsistent changes, often aggravate ADHD symptoms, and can cause frontal apathy and disinhibition. Clonidine has not been adequately examined but seems to have small or uncertain effects. Psychostimulants remain the treatment of choice because of their unique effect on attention. Multimodal treatments (medications plus psychosocial) might not be more effective than medications alone. PMID:9418743

Attentional problems in patients with attention deficit hyperactivity disorder (ADHD) have often been linked with deficits in cognitive control. Whether these deficits are associated with increased sensitivity to external salient stimuli remains unclear. To address this issue, we acquired functional brain images (fMRI) in 38 boys with and without ADHD (age: 11-16 years). To differentiate the effects of item novelty, contextual rareness and task relevance, participants performed a visual oddball task including four stimulus categories: a frequent standard picture (62.5%), unique novel pictures (12.5%), one repeated rare picture (12.5%), and a target picture (12.5%) that required a specific motor response. As a main finding, we can show considerable overlap in novelty-related BOLD responses between both groups, but only healthy participants showed neural deactivation in temporal as well as frontal regions in response to novel pictures. Furthermore, only ADHD patients, but not healthy controls, engaged wide parts of the novelty network when processing the rare but familiar picture. Our results provide first evidence that ADHD patients show enhanced neural activity in response to novel but behaviorally irrelevant stimuli as well as reduced habituation to familiar items. These findings suggest an inefficient use of neuronal resources in children with ADHD that could be closely linked to increased distractibility. PMID:25648705

While CON–DMN anti-correlation is associated with improved attention in ADHD, other circuitry supports improved attention in TD children. Greater CON–DMN anti-correlation supported better attentional control in children with ADHD, but worse attentional control in TD children. On the other hand, greater DMN–occipital anti-correlation supported better attentional control in TD children.

The cardinal symptoms of attention deficit hyperactivity disorder (ADHD)--inattention, hyperactivity and impulsiveness--are not specific and may be found in the general population and in other disorders. These symptoms are present in over 50% of patients with autism spectrum disorders (ASD). It thus seems quite clear that both problems can coexist in these patients. The usual pharmacological treatments for ADHD, methylphenidate and atomoxetine, appear to be useful in reducing the above-mentioned symptoms in patients with ADHD and ASD. Effectiveness seems to be lower in patients with ASD and tolerance is slightly poorer. This may be conditioned by a number of variables, including: the complexity of ASD, association with mental retardation, polypharmacotherapy, and so on. Given the long-term tolerance profile of methylphenidate and atomoxetine, these treatments appear to be a good alternative with which to improve the problems of attention and self-control these patients have. Nevertheless, further controlled studies are needed to confirm this proposition. PMID:23897149

Attention deficit hyperactivity disorder (ADHD) affects 1 to 10% of children and is characterised by a persistent pattern of inattention and/or hyperactivity/impulsivity. Over one-half of children with ADHD have associated conditions, including learning disabilities, conduct disorders, poor coordination, depression, anxiety, obsessive-compulsive disorders and bipolar disorders. CNS stimulant medication used in the management of ADHD is not permitted for use in competition by the International Olympic Committee (IOC) and this poses a problem for the physicians of patients with ADHD. On the one hand, attention and concentration are improved by stimulant medication and fine motor coordination and balance are improved after methylphenidate administration, but these therapeutic and sport-related benefits are not available to the athlete with ADHD who wishes to compete under IOC rules. It has been suggested that treatment with methylphenidate may be suitable for athletes with ADHD, as cessation of therapy 24 hours before competition is usually adequate to allow drug clearance which should avoid a positive result being returned on drug testing. More research is needed to establish whether stimulant medication for athletes with ADHD provides an unfair advantage in competition. PMID:10028130
Full Text Available Objective: Early recognition of negative emotions is considered to be of vital importance. It seems that children with attention deficit hyperactivity disorder have some difficulties recognizing facial emotional expressions, especially negative ones. This study investigated the preference of children with attention deficit hyperactivity disorder for negative (angry, sad facial expressions compared to normal children.Method: Participants were 35 drug naive boys with ADHD, aged between 6-11 years ,and 31 matched healthy children. Visual orientation data were recorded while participants viewed face pairs (negative-neutral pairs shown for 3000ms. The number of first fixations made to each expression was considered as an index of initial orientation. Results: Group comparisons revealed no difference between attention deficit hyperactivity disorder group and their matched healthy counterparts in initial orientation of attention. A tendency towards negative emotions was found within the normal group, while no difference was observed between initial allocation of attention toward negative and neutral expressions in children with ADHD .Conclusion: Children with attention deficit hyperactivity disorder do not have significant preference for negative facial expressions. In contrast, normal children have a significant preference for negative facial emotions rather than neutral faces.

Full Text Available A Brazilian Health Technology Assessment Bulletin (BRATS article regarding scientific evidence of the efficacy and safety of methylphenidate for treating attention deficit hyperactivity disorder (ADHD has caused much controversy about its methods. Considering the relevance of BRATS for public health in Brazil, we critically reviewed this article by remaking the BRATS search and discussing its methods and results. Two questions were answered: did BRATS include all references available in the literature? Do the conclusions reflect the reviewed articles? The results indicate that BRATS did not include all the references from the literature on this subject and also that the proposed conclusions are different from the results of the articles chosen by the BRATS authors themselves. The articles selected by the BRATS authors showed that using methylphenidate is safe and effective. However, the BRATS final conclusion does not reflect the aforementioned and should not be used to support decisions on the use of methylphenidate.

This article reviews studies examining the efficacy of behavioral interventions for the treatment of attention-deficit/hyperactivity disorder (ADHD). A specific emphasis is placed on evidence-based interventions that include parent training, classroom, academic, and peer interventions. Results indicate that school-aged children respond to behavioral interventions when they are appropriately implemented both at home and in the classroom setting. Combined treatments (behavioral management and stimulant medication) represent the gold standard in ADHD treatment and are often recommended as the first-line treatment option due to the many problems faced by children with ADHD. Diversity issues, although an important consideration in the treatment of ADHD, continue to remain an understudied area. Recommendations for future research are made pertaining to treatment sequencing with regard to behavior management as well as for subgroups of ADHD children who may respond best to specific treatments.

This study examined identification of emotional information in facial expression, prosody, and their combination in 23 adult patients with combined attention deficit-hyperactivity disorder (ADHD) versus 31 healthy controls (HC) matched for gender, age, and education. We employed a stimulus set which was carefully balanced for valence as well as recognizability of the expressed emotions as determined in an independent sample of HC to avoid potential biases due to different levels of task difficulty. ADHD patients were characterized by impaired recognition of all employed categories (neutral, happiness, eroticism, disgust, anger). Basic cognitive functions as assessed by neuropsychological testing, such as sustained attention, constancy of alertness, and verbal intelligence partially explained lower recognition rates. Removal of the correlated variance by means of regression analyses did not abolish lower performance in ADHD indicating deficits in social cognition independent of these neuropsychological factors (p recognition accuracy during bimodal presentation (p < 0.05) as compared to HC. These behavioral results can serve as foundation for future neuroimaging studies and point rather towards sensory-specific regions than audiovisual integration areas in perception of emotional information in adult ADHD.

Full Text Available Attention deficit hyperactivity disorder (ADHD is a chronic behavioral disorder characterized by persistent hyperactivity, impulsivity, and inattention that impairs educational achievement and/or social functioning. Its diagnosis is made by ascertaining whether the child′s specific behaviors meet the diagnostic and statistical manual of mental disorders-IV-revised criteria. Its etiology is still unclear but recent studies suggest that genetics plays a major role in conferring susceptibility. Comorbidity with psychiatric disorders such as anxiety disorder, depression, oppositional defiant disorder and conduct disorder; and with specific learning disability is not uncommon. Although medication works well in most cases of ADHD, optimal treatment requires integrated medical and behavioral treatment. Methylphenidate (MPH and atomoxetine are the two drugs being currently prescribed and their efficacy in decreasing the symptoms of ADHD is well documented. Pyschoeducational interventions in school can help increase the successful functioning of affected children and improve their academic performance. Almost half of affected children continue to show significant symptoms of the disorder into adolescence and young adulthood. The family physician can play an important role in detecting this condition early, coordinating its assessment and treatment, counseling the parents and classroom teacher, and monitoring the child′s academic and psychosocial progress on a long-term basis.

Full Text Available Attention deficit hyperactivity disorder (ADHD is the most common cause of behavioral disorders and learning problems at preschool and school ages. Patients with ADHD are frequently found to have comorbidities that present additional diagnostic and therapeutic problems and result in an even greater decrease in quality of life in patients. Thus, ADHD is frequently concurrent with epilepsy; in this case, not only the manifestations of ADHD are more common in epilepsy, but the latter is more often encountered in patients with ADHD than in those as a whole. The authors consider the epidemiological factors and causes, which may lead to a concurrence of these two diseases in the same patient, the principles of diagnosis and differential diagnosis of ADHD in epileptic patients, the specific features of treatment in this patient category. At the same time, the authors place emphasis on the fact that some antiepileptic drugs, such as barbiturates, may cause symptoms that mimic ADHD (in these cases, inattention and hyperactivity are adverse reactions of therapy and lessen or disappear after drug discontinuation or enhance the manifestations of ADHD in patients with a concurrence of these two diseases. On the other hand, care should be also taken to choose drugs for the treatment of ADHD due to the possible higher frequency of seizures. So preference should be given to the drugs having no negative effect on the course of comorbidities or those having a positive therapeutic effect against both diseases.
The main characteristic of attention deficit/hyperactivity disorder (ADHD) is a persistent pattern of inattention and/or hyperactivity-impulsivity which is more frequent and severe than is usually expected in individuals at a comparable level of development. ADHD is estimated to affect approximately 5.29% of school-aged children and is therefore the most common childhood onset psychological disorder. A conservative estimate of the annual societal cost of illness for ADHD in childhood and adolescence is USD 42.5 billion in the U.S. alone. Global sales of ADHD medicines could reach USD 4.3 billion by 2012. Despite the prevalence, high heritability and costs of ADHD, biological markers do not exist. Such biomarkers are in high demand as they would help eliminate the subjective diagnoses based on interviews and potentially allow for earlier diagnosis and personalized medicine. Lack of markers likely stems from several factors that complicate ADHD research and the assessment of pharmacological responses. This review analyses complicating factors in defining ADHD phenotype and etiology, identifying specific diagnostic markers and the difficulties in the assessment of pharmacogenomic markers. The dopamine transporter (DAT1) genotype and methylphenidate (MPH) response are detailed as an example of a biomarker. A recent report of a novel ADHD gene and its possible role as a biomarker is explored. Finally, suggestions for strategies and study designs for future research for the definition of effective ADHD biomarkers are made. PMID:20862396
Although generally considered a childhood disorder, attention-deficit/hyperactivity disorder (ADHD) can persist into adulthood and impede achievement in the workplace. Core ADHD symptoms of inattention, hyperactivity, and impulsivity can be associated with poor organization, time management, and interpersonal relationships. Employment levels, earning power, and productivity are reduced among individuals with ADHD compared with those without ADHD. Furthermore, the costs of employing individuals with ADHD are higher because of work absences and lost productivity. The primary care provider plays an integral role in managing ADHD symptoms and providing the necessary resources that will help individuals with ADHD succeed in the workplace. Pharmacotherapy can reduce ADHD symptoms and improve functioning; however, it is also important to consider how positive traits associated with ADHD, such as creative thinking, can be used in the workplace. Workplace accommodations and behavioral therapies, such as coaching, can also enhance time management and organizational skills. This review describes how ADHD symptoms affect workplace behaviors, the effect of ADHD on employment and workplace performance, and the management of ADHD in working adults. PMID:25295647

Full Text Available OBJECTIVES: Attention deficit hyperactivity disorder (ADHD in adults has been associated with disturbances of attention and executive functions. Furthermore, impairments of verbal and figural retrospective memory were reported. However, little is known about the effects of ADHD on prospective memory, the execution of delayed intentions in the future. METHODS: The present study compared the performance of 45 adult patients with ADHD not treated with stimulant medication with the performance of 45 matched healthy individuals on a paradigm of complex prospective memory which measured task planning, plan recall, self-initiation and execution. Furthermore, the contribution of other cognitive functions to prospective memory functioning was assessed, including measures of attention, executive functions and memory. RESULTS: A large-scale impairment could be observed in task planning abilities in patients with ADHD. Only negligible to small effects were found for plan recall, self-initiation and execution. Inhibition was identified to contribute significantly to performance on task planning. CONCLUSIONS: The present findings suggest that four cognitive components contribute to the performance of prospective memory. Impairments of prospective memory mainly emerged from deficient planning abilities in adults with ADHD. Implications on behavioral based intervention strategies are discussed.

Full Text Available Objective:To compare both global and specific domains of motor development of children with attention deficit hyperactivity disorder (ADHD with that of typically developing children.Methods:Two hundred children (50 children with clinical diagnoses of ADHD, according to the DSM-IV-TR and 150 typically developing controls, aged 5 to 10 years, participated in this cross-sectional study. The Motor Development Scale was used to assess fine and global motricity, balance, body schema, and spatial and temporal organization.Results:Between-group testing revealed statistically significant differences between the ADHD and control groups for all domains. The results also revealed a deficit of nearly two years in the motor development of children with ADHD compared with the normative sample.Conclusion:The current study shows that ADHD is associated with a delay in motor development when compared to typically developing children. The results also suggested difficulties in certain motor areas for those with ADHD. These results may point to plausible mechanisms underlying the relationship between ADHD and motor difficulties.

Full Text Available OBJECTIVES: The context of memory experiences is referred to as source memory and can be distinguished from the content of episodic item memory. Source memory represents a crucial part of biographic events and elaborate memory experiences. Whereas individuals with attention deficit hyperactivity disorder (ADHD were shown to have inefficient item memory, little is known about the context of memory experiences. METHODS: The present study compared 37 adult patients with a diagnosed ADHD with 40 matched healthy participants on a word list paradigm. Memory functions of encoding, retention and source discrimination were assessed. Furthermore, standardized measures of memory and executive control were applied in order to explore a qualitative differentiation of memory components. RESULTS: Adult patients with ADHD showed impaired performance in encoding of new information whereas the retention of encoded items was found to be preserved. The most pronounced impairment of patients with ADHD was observed in source discrimination. Regression models of cognitive functions on memory components supported some qualitative differentiation. CONCLUSIONS: Data analysis suggests a differential pattern of memory impairment in adults suffering from ADHD with a particular deficit in source discrimination. Inefficient source discrimination in adults with ADHD can affect daily functioning by limiting biographic awareness and disturbing general cognitive processes.

Attention-deficit hyperactivity disorder (ADHD) is a common neurobehavioral disorder, and its symptoms are hyperactivity and deficits in learning and memory. Physical exercise increases dopamine synthesis and neuronal activity in various brain regions. In the present study, we investigate the duration-dependence of the treadmill exercise on hyperactivity in relation with dopamine expression in ADHD. Spontaneously hypertensive rats were used for the ADHD rats and Wistar-Kyoto rats were used fo...
Full Text Available Kevin Nugent,1 Wallace Smart2,3 1Kinark Child and Family Services, Trent University and Sir Sanford Fleming College, Peterborough, ON, Canada; 2Department of Psychiatry, Faculty of Medicine and Dentistry, University of Alberta, Edmonton, AB, Canada; 3University of Lethbridge Health Centre, Lethbridge, AB, Canada Abstract: A PubMed review was conducted for papers reporting on attention-deficit/ hyperactivity disorder (ADHD in postsecondary students. The review was performed in order to determine the prevalence and symptomatology of ADHD in postsecondary students, to examine its effects on academic achievement, and discuss appropriate management. The prevalence of ADHD symptoms among postsecondary students ranges from 2% to 12%. Students with ADHD have lower grade point averages and are more likely to withdraw from courses, to indulge in risky behaviors, and to have other psychiatric comorbidities than their non-ADHD peers. Ensuring that students with ADHD receive appropriate support requires documented evidence of impairment to academic and day-to-day functioning. In adults with ADHD, stimulants improve concentration and attention, although improved academic productivity remains to be demonstrated. ADHD negatively impacts academic performance in students and increases the likelihood of drug and alcohol problems. Affected students may therefore benefit from disability support services, academic accommodations, and pharmacological treatment. Keywords: adults, academic performance, stimulants, treatment

This study was conducted in order to (a) compare the visual perceptions of seven-year-old children diagnosed with attention deficit hyperactivity disorder with those of normally developing children of the same age and development level and (b) determine whether the visual perceptions of children with attention deficit hyperactivity disorder vary with respect to gender, having received preschool education and parents` educational level. A total of 60 children, 30 with attention deficit hyperactivity disorder and 30 with normal development, were assigned to the study. Data about children with attention deficit hyperactivity disorder and their families was collected by using a General Information Form and the visual perception of children was examined through the Frostig Developmental Test of Visual Perception. The Mann-Whitney U-test and Kruskal-Wallis variance analysis was used to determine whether there was a difference of between the visual perceptions of children with normal development and those diagnosed with attention deficit hyperactivity disorder and to discover whether the variables of gender, preschool education and parents` educational status affected the visual perceptions of children with attention deficit hyperactivity disorder. The results showed that there was a statistically meaningful difference between the visual perceptions of the two groups and that the visual perceptions of children with attention deficit hyperactivity disorder were affected meaningfully by gender, preschool education and parents` educational status.

Twin, family and adoption studies have led to a solid understanding of the contribution of both genetic and environmental factors to the development of attention deficit/hyperactivity disorder (ADHD). We review recent studies under consideration of both methodological aspects and relevant findings. Heritability estimates in the range of 0.6 - 0.8 surpass those for most other child and adolescent psychiatric disorders. First degree relatives have elevated rates for ADHD, affective disorders, conduct disorders and substance abuse and dependency. The ADHD subtype of the index patient does not predict the subtype of other family members affected with ADHD; hence non-genetic factors seemingly account for this intrafamilial variability. Because the familial rates for ADHD are not higher in families of female in comparison to male index patients, there is no indication that the genetic loading is higher in affected females. Recently, rater effects have been discussed broadly: Whereas the heritability estimates are uniformly high independent of the informant (mother, father, teacher), the correlations between quantitatively rated symptoms are low between different informants. Knowledge of the formal genetic aspects of ADHD is a prerequisite for understanding the results of recent molecular genetic studies. PMID:12858257

For many years, attention-deficit hyperactivity disorder (ADHD) was thought to be a childhood-onset disorder that has a limited effect on adult psychopathology. However, the symptoms and impairments that define ADHD often affect the adult population, with similar responses to drugs such as methylphenidate, dexamphetamine, and atomoxetine, and psychosocial interventions, to those seen in children and adolescents. As a result, awareness of ADHD in adults has rapidly increased and new clinical practice has emerged across the world. Despite this progress, treatment of adult ADHD in Europe and many other regions of the world is not yet common practice, and diagnostic services are often unavailable or restricted to a few specialist centres. This situation is remarkable given the strong evidence base for safe and effective treatments. Here we address some of the key conceptual issues surrounding the diagnosis of ADHD relevant to practising health-care professionals working with adult populations. We conclude that ADHD should be recognised in the same way as other common adult mental health disorders, and that failure to recognise and treat ADHD is detrimental to the wellbeing of many patients seeking help for common mental health problems.

Full Text Available Background: : To evaluate the association of major dietary patterns identified by factor analysis and attention deficit hyperactivity disorder (ADHD in a group of Iranian school aged children.Materials and Method: : This cross-sectional study was conducted among 375 school-aged children in Tehran, Iran. Usual dietary intakes were assessed by a semi-quantitative food frequency questionnaire. DSM-IV questionnaire was used to determine the prevalence of ADHD. Major dietary patterns were identified by factor analysis. Results: The prevalence of ADHD was 9.7% in this population. We identified 4 major dietary patterns: "healthy", "western", "sweet" and "fast foods" dietary patterns. Children in top quintile of "sweet dietary pattern” score had greater odds for having ADHD as compared with those in the lowest quintile (Odds ratio: 3.95; 95% CI: 1.16, 15.31; p=0.03. Greater adherence to "fast food" dietary pattern was significantly associated with higher risk of having ADHD (Odds ratio: 3.21; 95% CI: 1.05, 10.90; p=0.03. No overall significant associations were seen between either healthy or western dietary patterns with ADHD. All these analysis were done in the controlled model for confounders.Conclusion: We found significant independent associations between "sweet" and "fast foods" dietary patterns and prevalence of ADHD. Prospective studies are required to confirm these findings

This study investigated the influence of drug-company funding on websites about attention-deficit hyperactivity disorder (ADHD). Websites in the top 60 for either Google or Yahoo!Xtra with information about causation and treatment were analysed. Likert scales, based on those used in previous similar studies, were developed to rate aetiological explanations and recommended treatment approaches, on a dimension from psycho-social to biological. Overall, the quality of information on websites was poor with a strong bias towards bio-genetic aetiological explanations of ADHD. Twenty-one of the 57 websites (37%) were funded by drug companies. The drug-company funded (DCF) websites were significantly more likely than non-DCF websites to recommend medication rather than psycho-social treatments. The selective lack of consideration of psycho-social treatments by DCF websites is discussed in relation to the relevant research literature, including the evidence in favour of a multimodal approach. The findings, which are consistent with previous similar studies in relation to websites about adult mental health problems, confirm that the pharmaceutical industry is seeking to influence public opinion via the internet.

Objective: To investigate the brain activation map during Go-NoGo tasks in children with attention deficit hyperactivity disorder (ADHD) and matched controls using functional MRI. Methods: Block designed BOLD functional MRI scan covering the whole brain was performed on 10 boys having ADHD and 11 healthy boys. The 2 groups were matched by age, sex, and handedness. Executing advanced inhibitory Go-NoGo tasks served as stimuli for all subjects. The fMRI data was analyzed by SPM99 (Statistical Parametric Mapping) software with statistic t-test to generate the activation map. Results: (1) The normal children showed significant activations in left thalamus and right cingulate gyrus and fewer activations in right middle frontal gyrus during stimulate controlled Go task, but the children with ADHD showed less activations in left thalamus. (2) In response controlled Go task, the normal children showed activations in right insula, cingulate gyrus and left frontal gyrus, while the ADHD children showed lower power of response in the right middle frontal gyrus.(3) In NoGo task, right middle frontal gyrus was the dominant activated regions, and left anterior cingulate, left middle frontal gyrus and right thalamus also had some activations in normal children, while the activations of right prefrontal decreased and the thalamus increased in ADHD boys. Conclusion: In children with ADHD, some dysfunctional brain areas, mainly the prefrontal lobe and anterior cingulate gyrus were found. Thalamus was also involved according to the brain activation map

One of the main aspects of theory of mind is intentionality which refers to recognizing other people's intentions in their behaviors. The aim of this study was to investigate intentionality in children with attention-deficit/hyperactivity disorder (ADHD). Thirty children with ADHD were compared to thirty age- and IQ-matched normal children. All participants were assessed using the moving shapes paradigm task which contains one large red and one small blue triangle moving around a black screen. They were asked to describe what the movements mean and how the triangles interact with each other. The answers were rated based on the accuracy, type of descriptions applied, mental states, and length of phrases. With regard to intentionality score, children with ADHD performed significantly worse than normal children (P < .05). Based on appropriateness score, the accuracy of patients' answers was lower in comparison with the control group. Children with ADHD used longer phrases as compared to controls. Children with ADHD can have problems with comprehending others' intentionality. This leads to impairment in social relationship. PMID:26613599
Full Text Available Attention-deficit/hyperactivity disorder (ADHD is a highly heritable neuropsychiatric disorder associated with significant impairments in occu¬pational, academic, neuropsychological, and social functioning. Central nervous system (CNS stimulants are recommended as first-line medication therapy for children. CNS stimulants include formulations of methylphenidate and amphetamine derivatives and are available in a large variety of immediate- and extended-release preparations. Extended-release preparations are often preferred to limit drug administration during school or work and may help to limit side effects associated with rapid fluctuations in serum concentration. Stimulant medication is by far the most commonly used treatment in managing children with ADHD, 10-20% of those who take such medication do now show clinically significant improvements in their primary ADHD symptom. Even when a favorable response is obtained, some children experience side effects that are of sufficient occurrence and severity to prevent continued use of stimulant medication. In such instances or when families are unwilling to consider a stimulant, non-stimulant medications may be appealing. This review focuses on etiology, assessment and treatment of ADHD with various stimulant and non-stimulant agents.

Method: This cross-sectional research involving 251 adolescents from 9 different schools in Ankara was carried out between April and June 2007. Adolescents were assessed in Child and Adolescent Behavior Disorders Screening and Rating Scale based on DSM-IV. A questionnaire was used for sociodemographic attributes. Screening and rating scale was completed by both class teacher and parent of the students. Results: According to the combined statements of parent and teacher 5.9% of the students had ADHD symptoms. The prevalence of ADHD was 12.7% and 27.4% on the basis of parent and teacher reports respectively. ADHD symptoms were significantly higher among boys on the basis of both teacher and parent reports (p<0.001. There was no significant difference between ADHD symptoms and socioeconomic status and parent education level. The prevalence of ODD was 46.4% and 52.5% among adolescents with ADHD symptoms according to parent and teacher assessments respectively. Conclusion: Informing parent and teachers about DEHB and other disruptive behaviors, and about the outcomes due these problems is important in view of early recognition of the problem, initiation of treatment and being supportive for the adolescent.
Full Text Available Abstract Background Attention deficit hyperactivity disorder (ADHD is increasingly recognized as a common disorder not only in children, but also in the adult population. Similarly, asthma also has a substantial prevalence among adults. Previous studies concerning a potential relationship between ADHD and asthma have not presented consistent results. Methods A cross-sectional study of 594 adult patients diagnosed with ADHD, compared with 719 persons from the general population. Information was collected between 1997 and 2005 using auto-questionnaires rating past and present symptoms of ADHD, co-morbid conditions, including asthma, and work status. Results The prevalence of asthma was significantly higher in the ADHD patient group compared to the controls, 24.4% vs. 11.3% respectively (OR = 2.54, 95% CI 1.89-3.44, and controls with asthma scored higher on ratings of both past and present symptoms of ADHD. Female ADHD patients had a significantly higher prevalence of asthma compared to male ADHD patients (30.9% vs. 18.2%, OR = 2.01, CI 1.36-2.95, but in controls a slight female preponderance was not statistically significant. In both ADHD patients and controls, having asthma was associated with an increased prevalence of symptoms of mood- and anxiety disorders. Conclusions The present findings point to a co-morbidity of ADHD and asthma, and these patients may represent a clinical and biological subgroup of adult patients with ADHD.
Full Text Available Attention deficit hyperactivity disorder (ADHD is a complex disorder, which can be seen as a disorder of life time, developing in preschool years and manifesting symptoms (full and/or partial throughout the adulthood; therefore, it is not surprising that there are no simple solutions. The aim of this paper is to provide a short and concise review which can be used to inform affected children and adults; family members of affected children and adults, and other medical, paramedical, non-medical, and educational professionals about the disorder. This paper has also tried to look into the process of how ADHD develops; what are the associated problems; and how many other children and adults are affected by such problems all over the world basically to understand ADHD more precisely in order to develop a better medical and or non-medical multimodal intervention plan. If pre-school teachers and clinicians are aware of what the research tells us about ADHD, the varying theories of its cause, and which areas need further research, the knowledge will assist them in supporting the families of children with ADHD. By including information in this review about the connection between biological behavior, it is hoped that preschool teachers and clinicians at all levels will feel more confident about explaining to parents of ADHD children, and older ADHD children themselves about the probable causes of ADHD.

Attention-deficit/hyperactivity disorder (ADHD) is a frequent mental disorder with childhood onset and high persistence into adulthood. There is much evidence that ADHD increases the risk for the development of other psychiatric disorders and functional problems in several domains of everyday life. In this study, the association of ADHD with gambling disorder (GD) was investigated. 163 adult subjects suffering from GD were examined for childhood and current ADHD according to DSM-5 as well as co-morbid psychiatric disorders. Moreover, characteristics of gambling behavior have been evaluated. The prevalence of lifetime ADHD was 28.8 %, with 25.2 % of the study population presenting ADHD as a full syndrome according to DSM-5. The prevalence of co-morbid substance use disorders and adjustment disorders and cluster B personality disorders was higher in GD patients with current ADHD than in the group without. Also, an increased rate of suicide attempts was detected in gamblers with ADHD. In contrast with gamblers without ADHD, those with ADHD were reported to spend more time with gambling, a sedative effect of gambling and a faster development of GD. The high prevalence of ADHD in patients with GD indicates that childhood ADHD is a risk factor for the development of GD in later life. Moreover, treatment of patients with GD and ADHD is complicated by a high rate of co-morbid disorders. Regarding therapeutic approaches, it should be considered that functional aspects of gambling differ in GD patients with and without ADHD. PMID:27328979

Despite a wealth of evidence for the role of genetics in attention deficit hyperactivity disorder (ADHD), specific and definitive genetic mechanisms have not been identified. Pathway analyses, a subset of gene-set analyses, extend the knowledge gained from genome-wide association studies (GWAS) by providing functional context for genetic associations. However, there are numerous methods for association testing of gene sets and no real consensus regarding the best approach. The present study applied six pathway analysis methods to identify pathways associated with ADHD in two GWAS datasets from the Psychiatric Genomics Consortium. Methods that utilize genotypes to model pathway-level effects identified more replicable pathway associations than methods using summary statistics. In addition, pathways implicated by more than one method were significantly more likely to replicate. A number of brain-relevant pathways, such as RhoA signaling, glycosaminoglycan biosynthesis, fibroblast growth factor receptor activity, and pathways containing potassium channel genes, were nominally significant by multiple methods in both datasets. These results support previous hypotheses about the role of regulation of neurotransmitter release, neurite outgrowth and axon guidance in contributing to the ADHD phenotype and suggest the value of cross-method convergence in evaluating pathway analysis results. © 2016 Wiley Periodicals, Inc.

Full Text Available Attention Deficit Hyperactivity disorder (ADHD does not have a single underlying pathophysiology which seems it has a multifaceted etiology. There are various contributing factors for ADHD, environmental and genetic being few of them. This neurobiological disorder has been a result of continuous actions of the risk factors. Neuroimaging study has indicated that children suffering from ADHD had immature brains compared to other children. This has pointed towards the fact that the Cerebellum, Basal Ganglia and the Prefrontal cortex parts of the brain are predominantly affected. The pharmacological & neuroimaging studies implicated that the dysregulation of the neuronal pathways of the Neurotransmitters (Dopamine and Norepinephrine being primarily responsible for ADHD. The principal treatment procedure involves Pharmacotherapy (Medication and other effective Psychotherapy (Psychopharmacological methods for ADHD. Presently immediate release Methylphenidate (Ritalin, Coencerta has been clinically approved for the diagnosis of ADHD. The psychotherapy evolves self-consciousness of sensory and cognitive thinking strengths and blind spots deliver some respite and enhanced enactment. The pharmacotherapy should strategize complete treatment plan including behavioural and educational aspects.

The aim of the present study was to compare the parenting styles in parents with and without adult attention deficit hyperactivity disorder (ADHD) who had children with ADHD. It was a case-control study with convenience sampling strategy. Participants were recruited from the parents of previously diagnosed children with ADHD referred to Imam Hossein Hospital, Tehran/ Iran. Ninety parents with adult ADHD and 120 normal parents were chosen by Conner's Adult ADHD Screening Scale (CAARS) and psychiatrist interview. Using Baumrind Parenting Styles Questionnaire and Arnold Parenting Scale, parenting styles were assessed in both the groups. Results from independent samples t-test indicated that Authoritarian parenting style (F = 0.576, p 0.022) and Over reacting style (F = 7.976, p 0.045) were significantly higher in cases. On the other hand, controls were using Permissive style (F = 0.131, p 0.044) more than cases. The results are consistent with prior studies; these findings can improve the content of parent training for children with ADHD, who have adult ADHD themselves. PMID:26264632

Abstract Background Individuals with Attention-Deficit/Hyperactive Disorder (ADHD) have unexplained difficulties on tasks requiring speeded processing of colored stimuli. Color vision mechanisms, particularly short-wavelength (blue-yellow) pathways, are highly sensitive to various diseases, toxins and drugs that alter dopaminergic neurotransmission. Thus, slow color processing might reflect subtle impairments in the perceptual encoding stage of stimulus color, which arise from hypodopaminergi...

Executive dysfunction has been shown to be a promising endophenotype in neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD). This article reviewed 26 studies that examined executive function comparing ASD and/or ADHD children. In light of findings from this review, the ASD + ADHD group appears to share impairment in both flexibility and planning with the ASD group, while it shares the response inhibition deficit with the ADHD group. Conversely, deficit in attention, working memory, preparatory processes, fluency, and concept formation does not appear to be distinctive in discriminating from ASD, ADHD, or ASD + ADHD group. On the basis of neurocognitive endophenotype, the common co-occurrence of executive function deficits seems to reflect an additive comorbidity, rather than a separate condition with distinct impairments.

A consensus of the literature suggests that when there is a dysfunction in the “brain reward cascade,” especially in the dopamine system, causing a low or hypo-dopaminergic trait, the brain may require dopamine for individuals to avoid unpleasant feelings. This high-risk genetic trait leads to multiple drug-seeking behaviors, because the drugs activate release of dopamine, which can diminish abnormal cravings. Moreover, this genetic trait is due in part to a

First, we discuss briefly and in simple terms the EEG analysis and processing techniques most used in the context of ADHD. We review techniques that both analyze individual EEG channels (univariate measures and study the statistical interdependence between different EEG channels (multivariate measures, the so-called functional brain connectivity. Among the former ones, we review the classical indices of absolute and relative spectral power and estimations of the complexity of the channels, such as the approximate entropy and the Lempel-Ziv complexity. Among the latter ones, we focus on the magnitude square coherence and on different measures based on the concept of generalized synchronization and its estimation in the state space. Second, from a historical point of view, we present the most important results achieved with these techniques and their clinical utility (sensitivity, specificity, and accuracy to diagnose ADHD.

Objective To investigate whether children with Attention Deficit/Hyperactivity Disorder have lower levels of Vitamin D3 at birth than matched controls. Material Umbilical cord blood samples collected at birth from 202 children later diagnosed with Attention Deficit/Hyperactivity Disorder were analysed for vitamin D content and compared with 202 matched controls. 25-OH vitamin D3 was analysed by liquid chromatography tandem mass spectrometry. Results No differences in cord blood vitamin D concentration were found between children with Attention Deficit/Hyperactivity Disorder (median 13.0 ng/ml) and controls (median 13.5 ng/ml) (p = 0.43). In a logistic regression analysis, Attention Deficit/Hyperactivity Disorder showed a significant association with maternal age (odds ratio: 0.96, 95% confidence interval: 0.92–0.99) but not with vitamin D levels (odds ratio: 0.99, 95% confidence interval: 0.97–1.02). Conclusion We found no difference in intrauterine vitamin D levels between children later developing Attention Deficit/Hyperactivity Disorder and matched control children. However, the statistical power of the study was too weak to detect an eventual small to medium size association between vitamin D levels and Attention Deficit/Hyperactivity Disorder. PMID:26509435

Full Text Available UNLABELLED: Attention deficit hyperactivity disorder (ADHD symptoms can be difficult to treat. We previously reported that a 20-session brain-computer interface (BCI attention training programme improved ADHD symptoms. Here, we investigated a new more intensive BCI-based attention training game system on 20 unmedicated ADHD children (16 males, 4 females with significant inattentive symptoms (combined and inattentive ADHD subtypes. This new system monitored attention through a head band with dry EEG sensors, which was used to drive a feed forward game. The system was calibrated for each user by measuring the EEG parameters during a Stroop task. Treatment consisted of an 8-week training comprising 24 sessions followed by 3 once-monthly booster training sessions. Following intervention, both parent-rated inattentive and hyperactive-impulsive symptoms on the ADHD Rating Scale showed significant improvement. At week 8, the mean improvement was -4.6 (5.9 and -4.7 (5.6 respectively for inattentive symptoms and hyperactive-impulsive symptoms (both p<0.01. Cohen's d effect size for inattentive symptoms was large at 0.78 at week 8 and 0.84 at week 24 (post-boosters. Further analysis showed that the change in the EEG based BCI ADHD severity measure correlated with the change ADHD Rating Scale scores. The BCI-based attention training game system is a potential new treatment for ADHD. TRIAL REGISTRATION: ClinicalTrials.gov NCT01344044.

Relatively recently, neurocognitive and neuroimaging studies have indicated that individuals with attention-deficit/hyperactivity disorder (ADHD) may have deficits in a range of timing functions and their underlying neural networks. Despite this evidence, timing deficits in ADHD are still somewhat neglected in the literature and mostly omitted from reviews on ADHD. There is therefore a lack of integrative reviews on the up-to-date evidence on neurocognitive and neurofunctional deficits of timing in ADHD and their significance with respect to other behavioural and cognitive deficits. The present review provides a synthetic overview of the evidence for neurocognitive and neurofunctional deficits in ADHD in timing functions, and integrates this evidence with the cognitive neuroscience literature of the neural substrates of timing. The review demonstrates that ADHD patients are consistently impaired in three major timing domains, in motor timing, perceptual timing and temporal foresight, comprising several timeframes spanning milliseconds, seconds, minutes and longer intervals up to years. The most consistent impairments in ADHD are found in sensorimotor synchronisation, duration discrimination, reproduction and delay discounting. These neurocognitive findings of timing deficits in ADHD are furthermore supported by functional neuroimaging studies that show dysfunctions in the key inferior fronto-striato-cerebellar and fronto-parietal networks that mediate the timing functions. Although there is evidence that these timing functions are inter-correlated with other executive functions that are well established to be impaired in the disorder, in particular working memory, attention, and to a lesser degree inhibitory control, the key timing deficits appear to survive when these functions are controlled for, suggesting independent cognitive deficits in the temporal domain. There is furthermore strong evidence for an association between timing deficits and behavioural

Attention-deficit/hyperactivity disorder (ADHD) is a widely studied neurodevelopmental disorder. It is a highly heterogeneous condition, encompassing different types of expression. The predominantly inattentive type is the most prevalent and the most stable over the lifetime, yet it is the least-studied presentation. To increase understanding of its cognitive profile, 29 children with attention-deficit/hyperactivity disorder of predominantly inattentive type (ADHD-I) and 29 matched controls, aged 7-15 years, had their attentional abilities assessed through the Conners' continuous performance test. Diffusion tensor imaging data were collected for all of the participants using a 3.0-T MRI system. Fractional anisotropy (FA) values were obtained for 20 fiber tracts, and brain-behavior correlations were calculated for 42 of the children. The ADHD-I children differed significantly from the typically developing (TD) children with respect to attentional measures, such as the ability to maintain response-time consistency throughout the task (Hit RT SE and Variability), vigilance (Hit RT ISI and Hit RT ISI SE), processing speed (Hit RT), selective attention (Omissions), sustained attention (Hit RT Block Change), error profile (Response Style), and inhibitory control (Perseverations). Evidence of significant differences between the ADHD-I and the TD participants was not found with respect to the mean FA values in the fiber tracts analyzed. Moderate and strong correlations between performance on the attention indicators and the tract-average FA values were found for the ADHD-I group. Our results contribute to a better characterization of the attentional profile of ADHD-I individuals and suggest that in children and adolescents with ADHD-I, attentional performance is mainly associated with the white matter structure of the long associative fibers that connect anterior-posterior brain areas.

This control deficit could be due to primarily reduced attentional capacities or, e. g., to overshooting orienting to unexpected events. Here, we aimed at identifying disease-related abnormalities of novelty processing and, therefore, studied event-related potentials (ERP) to respective stimuli in adult ADHD patients compared to healthy subjects. Met...

Throughout this decade, there has been significant research into pharmacotherapies for attention-deficit hyperactivity disorder (ADHD). This article considers the efficacy and safety of five of the more novel long-acting pharmacological treatments recently approved by the FDA for marketing in the US for paediatric ADHD, along with an alpha(2)-adrenoceptor agonist in preparation. Reviewed treatments include the non-stimulant atomoxetine, three novel extended-release (XR) stimulant preparations: dexmethylphenidate, lisdexamfetamine dimesylate and the methylphenidate transdermal system (TDS), and the recently approved XR alpha(2)-adrenoceptor agonist, guanfacine. Dexmethylphenidate XR is a stimulant treatment in a single isomer form, and has an efficacy and tolerability similar to two doses of immediate-release (IR) dexmethylphenidate when taken 4 hours apart, but is dosed at half of the usual d,l-methylphenidate dose. Dexmethylphenidate XR utilizes a beaded bimodal release, with 50% initially released and another 50% released 4 hours later to provide benefit lasting up to 10-12 hours. Lisdexamfetamine was the first stimulant treatment approved as a prodrug, whereby the single isomer d-amfetamine remains pharmacologically inactive until activated by cleaving the lysine. Its efficacy and tolerability are generally consistent with that of XR mixed amfetamine salts, with this activation method and more consistent absorption generally resulting in up to an 11- to 13-hour benefit. The methylphenidate TDS patch utilizes skin absorption to provide predictable and uniform delivery of methylphenidate when worn for 9 hours/day. The efficacy and tolerability of the methylphenidate TDS patch is generally consistent with that of osmotic-controlled release oral system (OROS) methylphenidate, providing benefit for about 11-12 hours. Because of their formulation, lisdexamfetamine and methylphenidate each have an onset of effect at about 2 hours after administration. An adjustable

Full Text Available Objective. Adults with attention deficit hyperactivity disorder (ADHD display affective problems and impaired attention. Mood in ADHD can be improved by mindful awareness practices (MAP, but results are mixed regarding the enhancement of attentional performance. Here we evaluated MAP-induced changes in quality of life (QoL, mood, and attention in adult ADHD patients and controls using more measures of attention than prior studies. Methods. Twenty-one ADHD patients and 8 healthy controls underwent 8 weekly MAP sessions; 22 similar patients and 9 controls did not undergo the intervention. Mood and QoL were assessed using validated questionnaires, and attention was evaluated using the Attentional Network Test (ANT and the Conners Continuous Performance Test (CPT II, before and after intervention. Results. MAP enhanced sustained attention (ANT and detectability (CPT II and improved mood and QoL of patients and controls. Conclusion. MAP is a complementary intervention that improves affect and attention of adults with ADHD and controls.

Nowadays the pharmacological treatment of the attention deficit hyperactivity disorder (ADHD) is based on amphetamine derivatives (i.e. methylphenidate). However, these drugs induce a large array of adverse side effects, thus less aggressive psychostimulant drugs (i.e. caffeine) are being proposed in the management of ADHD. Following this tendency, we decided to study the possible therapeutic use of caffeine in an animal model of ADHD, namely the neonatal 6-hydroxy-dopamine (6-OHDA)-lesioned rat. Therefore, at postnatal day 7 rats were lesioned at the left striatum with 6-OHDA or with saline. Thereafter, at postnatal day 25 their activity and attention were measured with the Olton maze before caffeine was administered ad libitum in the drinking water. Next, after 14 days of caffeine treatment, we repeated these measurements to assess the effect of caffeine on motor activity and attention deficit. Interestingly, while no changes in the motor activity measurements were observed before and after caffeine administration, a significant improvement in the attention deficit of the 6-OHDA lesioned rats was achieved after caffeine treatment. Thus, our results led us to hypothesize that caffeine might be useful to manage the attention deficit during the prepubertal period of ADHD. PMID:21362462

We conducted a functional analysis of elopement in an outdoor setting for a child with a diagnosis of attention deficit hyperactivity disorder. A subsequent treatment consisting of noncontingent attention and time-out was demonstrated to be effective in eliminating elopement. Modifications of functional analysis procedures associated with the occurrence of elopement in a natural setting are demonstrated.

A deficit in inhibition may underlie some of the symptoms of Attention-deficit/hyperactivity disorder (ADHD), particularly impulsivity. However, the data on inhibitory deficits in children with ADHD are mixed. Moreover, there has been little characterization of inhibitory processes in animal models of ADHD. Pavlov’s conditioned inhibition procedure allows a direct assessment of the inhibitory status of a stimulus via summation and retardation tests. Therefore, in the current study we examined...

Symptoms begin in childhood and may persist into adolescence and adulthood. Currently available pharmacological treatment options for attention-deficit/hyperactivity disorder in children and adolescents include stimulants that are efficacious and well tolerated; however, many of these preparations require multiple daily dosing and have the potential for abuse. Lisdexamfetamine dimesylate, the first prodrug stimulant, was developed to provide a longer duration of effect. It demonstrates a predictable delivery of the active drug, d-amphetamine, with low interpatient variability, and has a reduced potential for abuse. A literature search of the MEDLINE database and clinical trials register from 1995–2011, as well as relevant abstracts presented at annual professional meetings, on lisdexamfetamine dimesylate in children and adolescents were included for review. This article presents the pharmacokinetic profile, efficacy, and safety of lisdexamfetamine dimesylate for the treatment of attention-deficit/hyperactivity disorder in children and, more recently, in adolescents.Keywords: lisdexamfetamine dimesylate, prodrug stimulant, attention-deficit and hyperactivity disorders, safety, efficacy, children, adolescents

The vast majority of studies that have examined the latent structure of attention deficit/hyperactivity disorder (ADHD) in children and adolescents have concluded that ADHD has a dimensional latent structure. In other words, ADHD symptomatology exists along a continuum and there is no natural boundary or qualitative distinction (i.e., taxon) separating youth with ADHD from those with subclinical inattention or hyperactivity/impulsivity problems. Although adult ADHD appears to be less prevalen...

Attention deficit/hyperactivity disorder (ADHD) is a frequent and commonly studied neuropsychiatric disorder in children and adolescents. The symptoms of ADHD include inattention and/or hyperactivity and impulsivity. Diagnosis of ADHD requires a persistent pattern of symptoms beginning before the age of 7 except for secondary ADHD. Secondary ADHD may occur as a consequence of childhood traumatic brain injury. A patient with secondary ADHD as a result of right basal ganglia injury is presented...
Full Text Available Abstract Background Individuals with Attention-Deficit/Hyperactive Disorder (ADHD have unexplained difficulties on tasks requiring speeded processing of colored stimuli. Color vision mechanisms, particularly short-wavelength (blue-yellow pathways, are highly sensitive to various diseases, toxins and drugs that alter dopaminergic neurotransmission. Thus, slow color processing might reflect subtle impairments in the perceptual encoding stage of stimulus color, which arise from hypodopaminergic functioning. Presentation of hypotheses 1 Color perception of blue-yellow (but not red-green stimuli is impaired in ADHD as a result of deficient retinal dopamine; 2 Impairments in the blue-yellow color mechanism in ADHD contribute to poor performance on speeded color naming tasks that include a substantial proportion of blue-yellow stimuli; and 3 Methylphenidate increases central dopamine and is also believed to increase retinal dopamine, thereby normalizing blue-yellow color perception, which in turn improves performance on the speeded color naming tasks. Testing the hypothesis Requires three approaches, including:1 direct assessment of color perception in individuals with ADHD to determine whether blue-yellow color perception is selectively impaired; 2 determination of relationship between performance on neuropsychological tasks requiring speeded color processing and color perception; and 3 randomized, controlled pharmacological intervention with stimulant medication to examine the effects of enhancing central dopamine on color perception and task performance Implications of hypothesis If substantiated, the findings of color perception problems would necessitate a re-consideration of current neuropsychological models of attention-deficit/hyperactivity disorder, guide psycho-education, academic instruction, and require consideration of stimulus color in many of the widely used neuropsychological tests.

Previous structural imaging studies have revealed gray matter volume abnormalities to reflect the etiology of attention deficit hyperactivity disorder (ADHD), however, which are confounded by age, medication and comorbidity and also ignore the core feature of brain structure in the executive impairments of ADHD. In the present study, we explored gray matter volume abnormalities in male children and adolescents with ADHD who were drug-naive and without comorbidities, and tried to connect structural data and behavioral executive dysfunction to provide more information regarding the brain-behavior relationships in ADHD. Seventy-two male subjects (37 patients and 35 controls) underwent three-dimensional high-resolution structural magnetic resonance imaging and executive function assessments, including the Stroop Color-Word Test and Wisconsin Card Sorting Test (WCST). Voxel-based morphometry with diffeomorphic anatomical registration through exponentiated Lie algebra was used to identify gray matter volume differences between the ADHD and controls. Correlation analyses were performed to identify neuroanatomical deficits that were associated with executive dysfunctions. Significantly reduced gray matter volumes were identified in the right orbitofrontal cortex, right primary motor/premotor cortex, left anterior cingulate cortex and left posterior midcingulate cortex of ADHD patients compared with controls (PADHD at early illness stage. The correlations between structural abnormalities and executive dysfunction suggest that neuroanatomical substrate deficits are implicated in the pathophysiology of ADHD. PMID:26049007
