Attention Deficit Disorder

Internet Resources

Because so many experiences of AD/HD are 'internalized' for girls, we can only become fully aware of the issues with which they struggle by asking them directly.
Studies reveal that up to 80 percent of the time, ADD cannot be identified in the physician's office, presumably because the one-to-one social context with a (frequently) male authority figure mediates against the occurrence of symptoms.

A valuable tool to help determine if there are problems in the prefrontal cortex, anterior cingulate gyrus, basal ganglia, temporal lobes or deep limbic system.
The other feature that strikes me as being at the heart of the ADD myth is the focus on disease and disability. Absent from this perspective is any mention of a child's potential or other manifestations of health, traits that are crucial in helping a child achieve success in life.

Our objective is to promote awareness to AD/HD and to provide information and as much free practical help as we can to those with the condition, both adults and children, their families in the UK and around the World via this website.

Although animals cannot be used to study complex human behaviour such as language, they do have similar basic functions. In fact, human disorders that have animal models are better understood than disorders that do not. ADHD is a heterogeneous disorder. The relatively simple nervous systems of rodent models have enabled identification of neurobiological changes that underlie certain aspects of ADHD behaviour. Several animal models of ADHD suggest that the dopaminergic system is functionally impaired. Some animal models have decreased extracellular dopamine concentrations and upregulated postsynaptic dopamine D1 receptors (DRD1) while others have increased extracellular dopamine concentrations. In the latter case, dopamine pathways are suggested to be hyperactive. However, stimulus-evoked release of dopamine is often decreased in these models, which is consistent with impaired dopamine transmission. It is possible that the behavioural characteristics of ADHD result from impaired dopamine modulation of neurotransmission in cortico-striato-thalamo-cortical circuits. There is considerable evidence to suggest that the noradrenergic system is poorly controlled by hypofunctional a2-autoreceptors in some models, giving rise to inappropriately increased release of norepinephrine. Aspects of ADHD behaviour may result from an imbalance between increased noradrenergic and decreased dopaminergic regulation of neural circuits that involve the prefrontal cortex. Animal models of ADHD also suggest that neural circuits may be altered in the brains of children with ADHD. It is therefore of particular importance to study animal models of the disorder and not normal animals. Evidence obtained from animal models suggests that psychostimulants may not be acting on the dopamine transporter to produce the expected increase in extracellular dopamine concentration in ADHD. There is evidence to suggest that psychostimulants may decrease motor activity by increasing serotonin levels. In addition to providing unique insights into the neurobiology of ADHD, animal models are also being used to test new drugs that can be used to alleviate the symptoms of ADHD.

Although the differences between AS and ADHD can be noted and may lead to some different initial treatment approaches, eventually you must focus on your individual child's behavior and not a diagnosis.

Approaches to the diagnosis and treatment of attention-deficit hyperactivity disorder (ADHD) are undergoing a major change as a result of information from studies on the genetics of ADHD and the use of new neuroimaging technologies. Moreover, pharmacogenomics, although still in its infancy, will provide a basis for much more sophisticated treatment strategies for ADHD, particularly once more information is available about the genetics of ADHD.

In this article, an overview of attention-deficit/hyperactivity disorder (ADHD) is presented from a biopsychosocial perspective, an attempt to circumvent disparate psychological and medical viewpoints and offer a broader, more integrated view of ADHD. Through a review of the current literature on ADHD treatment within the clinical field, as well as intervention strategies for ADHD within the educational field, the author proposes the self-regulated behavior paradigm. This person-centered paradigm uses both pathological and growth-oriented constructs of human nature. As such, it offers the advantage of being able to integrate pathologically oriented approaches with growth-oriented approaches within a single comprehensive intervention plan.The impact of this approach in helping people with ADHD is discussed.

The influence of age on a selective attention task was studied in a sample of children with and without Attention Deficit Hyperactivity Disorder (ADHD). The impact of methylphenidate (MPH) treatment on selective attention was also investigated in the children with ADHD. Two age groups of children with ADHD and two age groups of control children were tested using a timed computer task. The task consisted of identifying visual target stimuli under various distracter conditions. Distracters varied on the basis of modality (i.e., visual, auditory, or both) and task relevance (i.e., meaningful or irrelevant). Reaction times and accuracy were measured. Children with ADHD were less efficient on the selective attention task than were children without ADHD, and older children were more efficient than younger children in both groups. Children without ADHD were influenced more by the nature of distracters than were children with ADHD. For children with ADHD, MPH improved performance overall.

ADD is a made-up term to convince society to lower expectations of itself, to suppress the weak-minded into depression and to expand the business of insecurity and fear. Powerful people find it important to keep the majority of society convinced that they are stupid and unable. Keeping the masses insecure and unsure of their abilities is a good way to maintain peace, ensure the continuance of their power and profit economically.

There is one other factor I want to include, it's not the most researched or interesting but it's a factor none-the-less. It's boredom. I hear teachers talk all the time about this really bright kid who doesn't work up to their potential, doesn't turn their work in or doesn't seem to care. Sometimes, it's not ADHD, anxiety, LD, SID or other topics we talked about. There will be times when we run across kids who stopped trying because the work is too easy or uninteresting. So attention remains elusive. We can't assume that because a kid meets the criteria in the DSM for any one thing that this means it's the diagnosis. Attention, or the lack of it, is a co-occurring phenomenon with many possible diagnoses or sometimes none at all.
Stephenie J Saunders
Using a root cause analysis framework, we identified system- and human-level factors that were perceived to impede communication and coordination of care for this population of children with attention-deficit/hyperactivity disorder. These results suggest that better organizational policies that define provider responsibilities and accountability, support the coordination of care, bridge relationships between agencies, and provide additional education and resources may improve collaboration. Additional study is needed to assess the generalizability of these finding to other settings.
James P. Guevara et al
While norepinephrine (NE) and dopamine (DA) are certainly not the only neurotransmitters involved in ADHD, there is considerable evidence that these neurotransmitters play essential roles in attention and thinking. It may be an artifact to attempt to attribute unique functions to each neurotransmitter since they collaborate in facilitating many cognitive and affective functions. Both agents contribute to maintaining alertness, increasing focus, and sustaining thought, effort, and motivation. NE and DA are structurally very similar, differing only in the presence of a hydroxyl group; DA is a precursor to NE synthesis in the brain. However, distinctions in their sources of origin and their projections in the brain and differences in the behavioral effect of selective alternations suggest that these neurotransmitters have discrete complementary roles in the brain. Although these neurotransmitters affect related components of attention, they activate distinct receptors including specific subtypes of NE and DA, usually identified as D1, D2, and D3 receptors, etc.

Unlike such psychiatric disorders as depression, schizophrenia, and bipolar illness, which generally have their onset in adulthood, there are a few psychiatric disorders in which onset in childhood is part of the diagnostic criteria. Two of these childhood-onset conditions, autistic disorder (AD) and attention-deficit/hyperactivity disorder (ADHD), illustrate both the behavioral heterogeneity that makes diagnosis a challenge and the potential of genetic analysis in the study of normal and abnormal behaviors. AD, while rare, is probably the best-validated psychiatric disorder in childhood (Rutter and Schopler 1988), whereas ADHD is the most common such disorder. These two conditions illustrate the diversity of behavioral phenotypes yet also exemplify some common aspects of the childhood-onset conditions.
Susan Smalley
Attention-deficit/hyperactivity disorder (ADHD) is the most commonly diagnosed behavioral disorder in childhood and likely represents an extreme of normal behavior. ADHD significantly impacts learning in school-age children and leads to impaired functioning throughout the life span. There is strong evidence for a genetic etiology of the disorder, although putative alleles, principally in dopamine-related pathways suggested by candidate-gene studies, have very small effect sizes. We use affected-sib-pair analysis in 203 families to localize the first major susceptibility locus for ADHD to a 12-cM region on chromosome 16p13 (maximum LOD score 4.2; P=.000005), building upon an earlier genomewide scan of this disorder. The region overlaps that highlighted in three genome scans for autism, a disorder in which inattention and hyperactivity are common, and physically maps to a 7-Mb region on 16p13. These findings suggest that variations in a gene on 16p13 may contribute to common deficits found in both ADHD and autism.

Researchers now believe that a gene variation associated with Attention-Deficit/Hyperactivity Disorder (AD/HD) first appeared 10,000 to 40,000 years ago and was probably a significant advantage to the early humans who had it.

The International Multi-centre ADHD Gene (IMAGE) project exemplifies current collaborative research efforts on the genetics of ADHD. This European multi-site project is well placed to take advantage of the resources that are emerging following the sequencing of the human genome and the development of international resources for whole genome association analysis. As a result of IMAGE and other molecular genetic investigations of ADHD, we envisage a rapid increase in the number of identified genetic variants and the promise of identifying novel gene systems that we are not currently investigating, opening further doors in the study of gene functionality.
Jonna Kuntsi et al
The present study was dedicated to investigate the influence of Methylphenidate (MPH) on cortical processing of children who were diagnosed with different subtypes of Attention Deficit Hyperactivity Disorder (ADHD). As all of the previous studies investigating power differences in different frequency bands have been using EEG, mostly with a relatively small number of electrodes our aim was to obtain new aspects using high density magnetoencephalography (MEG).... Main effects induced by medication were found in frontal regions. Theta band activity increased over the left hemisphere after MPH application. This finding contradicts EEG results of several groups who found lower levels of Theta power after MPH application. As relative Theta correlates with D2 test improvement we conclude that MEG provide complementary and therefore important new insights to ADHD.

A brief overview of the most common medications used in the UK for the treatment of ADHD.
Children with Attention Deficit/Hyperactivity Disorder (ADHD) often perform poorly on tasks requiring sustained and systematic attention to stimuli for extended periods of time. The current paper tested the hypothesis that such deficits are the result of observable abnormalities in search behaviour (e.g., attention-onset, -duration and -sequencing), and therefore can be explained without reference to deficits in non-observable (i.e., cognitive) processes. Forty boys (20 ADHD and 20 controls) performed a computer-based complex discrimination task adapted from the Matching Familiar Figures Task with four different fixed search interval lengths (5-, 10-, 15- and 20-s). Children with ADHD identified fewer targets than controls (p < 0.001), initiated searches later, spent less time attending to stimuli, and searched in a less intensive and less systematic way (p's < 0.05). There were significant univariate associations between ADHD, task performance and search behaviour. However, there was no support for the hypothesis that abnormalities in search carried the effect of ADHD on performance. The pattern of results in fact suggested that abnormal attending during testing is a statistical marker, rather than a mediator, of ADHD performance deficits. The results confirm the importance of examining covert processes, as well as behavioural abnormalities when trying to understand the psychopathophyiology of ADHD.

Attention deficit hyperactivity disorder (ADHD) is estimated to affect 3% of school age children in the United States, and is the most commonly diagnosed behavior disorder in childhood. The clinical diagnoses of ADHD in the DSM-IV are based on subjective reports of developmentally inappropriate behaviors within three symptom domains-inattention, impulsivity and hyperactivity-with the onset of symptoms before 7 years of age and functional impairment across at least two settings. ADHD may be associated with a number of comorbid psychiatric conditions as well as with impaired academic performance and family emotional distress. While it was previously though that the disorder remitted before or during adolescence, it has become well established that many patients will have an illness course that persists well into adulthood. Recent research in the fields of genetics, neuropsychology, neuroanatomy, neurochemistry and neuropharmacology have lead to possible hypotheses as to the origins of ADHD. Pharmacological treatment, particularly with stimulant drugs such as methylphenidate and D-amphetamine, is the most studied aspect of management, although other forms of treatment (e.g. behavior therapy, parent training) are important parts of good clinical care.

Attention-deficit hyperactivity disorder (ADHD) is described as the most common neurobehavioral condition of childhood. We raise the concern that ADHD is not a disease per se but rather a group of symptoms representing a final common behavioral pathway for a gamut of emotional, psychological, and/or learning problems. Increasing numbers of children, especially boys, are diagnosed with ADHD and treated with stimulant medications according to a simplified approach. Methodical review of the literature, however, raised concerning issues. "Core" ADHD symptoms of inattentiveness, hyperactivity and impulsivity are not unique to ADHD. Rates of "comorbid" psychiatric and learning problems, including depression and anxiety, range from 12 to 60%, with significant symptom overlap with ADHD, difficulties in diagnosis, and evidence-based treatment methods that do not include stimulant medications. No neuropsychologic test result is pathognomic for ADHD, and structural and functional neuroimaging studies have not identified a unique etiology for ADHD. No genetic marker has been consistently identified, and heritability studies are confounded by familial environmental factors. The validity of the Conners' Rating Scale-Revised has been seriously questioned, and parent and teacher "ratings" of school children are frequently discrepant, suggesting that use of subjective informant data via scale or interview does not form an objective basis for diagnosis of ADHD. Empiric diagnostic trials of stimulant medication that produce a behavioral response have been shown not to distinguish between children with and without "ADHD." In summary, the working dogma that ADHD is a disease or neurobehavioral condition does not at this time hold up to scrutiny of evidence. Thorough evaluation of symptomatic children should be individualized, and include assessment of educational, psychologic, psychiatric, and family needs.
Lydia Furman
ADHD is caused by differences in neurotransmitter patterns in certain parts of the brain. Neurotransmitters are chemicals that make it possible for nerve impulses to travel from one nerve cell to another, and therefore play an essential role in the functioning of the brain. The brain performs a vast range of tasks or functions, allowing us, for instance, to see, hear, think, speak and move. Each function is performed by a different part of the brain. In individuals with ADHD there are lower than normal levels of certain neurotransmitters (especially dopamine) in the regions of the brain that are responsible for regulating behaviour and attention.
