ADHD has an estimated worldwide prevalence of 5 percent, so the long-term outcome of children with ADHD is a major concern, according to the study background. Rachel G. Klein, Ph.D., of the Child Study Center at NYU Langone Medical Center in New York, and colleagues report the adult outcome (follow-up at average age of 41 years) of boys who were diagnosed as having ADHD at an average age of 8 years. The study included 135 white men with ADHD in childhood, free of conduct disorder (probands), and a comparison group of 136 men without childhood ADHD. "On average, probands had 2½ fewer years of schooling than comparison participants … 31.1 percent did not complete high school (vs. 4.4 percent of comparison participants) and hardly any (3.7 percent) had higher degrees (whereas 29.4 percent of comparison participants did). Similarly, probands had significantly lower occupational attainment levels," the authors note. "Given the probands' worse educational and occup...

Matthew Pontifex and colleagues use an EEG cap to observe mind exercise in research contributors. Credit score: Picture courtesy of Michigan State College A couple of minutes of train may help youngsters with consideration deficit hyperactivity dysfunction carry out higher academically, in response to a brand new research led by a Michigan State College researcher. The research, printed within the present subject of the  Journal of Pediatrics , reveals for the primary time that children with ADHD can higher drown out distractions and deal with a process after a single bout of train. Scientists say such "inhibitory management" is the primary problem confronted by individuals with the dysfunction. "This gives some very early proof that train may be a instrument in our nonpharmaceutical therapy of ADHD," stated Matthew Pontifex, MSU assistant professor of kinesiology, who led the research. "Possibly our first plan of action that w...

The ADHD VOICES -- Voices on Identity, Childhood, Ethics and Stimulants - - study has worked with 151 families in the UK and the USA to examine ethical and societal issues surrounding attention deficit hyperactivity disorder (ADHD), particularly the use of treatments such as methylphenidate (Ritalin). The project has been led by biomedical ethicist Dr Ilina Singh from King's College London and was funded by the Wellcome Trust. Dr Singh and colleagues interviewed children and their families about ADHD, behaviour, medication and identity across four contexts: home, school, the doctor's office and peer groups. The report is intended not only to highlight ethical and social issues surrounding ADHD but also to help families, doctors, teachers and the children themselves to understand from a child's perspective what it is like to live with ADHD. "ADHD is a very emotive subject, which inspires passionate debate. Everyone seems to have an opinion about the condition, ...

"About 25 percent of the time, when a child has ADHD, there's a parent that has ADHD," said Mark Stein, UIC professor of pediatrics and psychiatry and principal i nvestigator of the study. "We realize this is a weakness in our service delivery models, because often clinicians focus on just treating the child and ignore the fact that another family member has ADHD." Two treatments are very effective for children with ADHD: behavior modification and stimulant medication. Both require "a very dedicated, organized person, which, if you have ADHD, that's going to be a challenge for you," said Stein, who noted that treatment is often administered by the mother, and that women are less likely to have their ADHD identified. The Treating Mothers First Study will identify mothers of children between ages 4 and 8 with behavior problems who are at risk for ADHD -- and evaluate both the mother and child. Mothers with ADHD will receive either a long-acti...

In the first study, Mayo Clinic researchers required parents and teachers of children coming in for their first ADHD consultation , defined by some combination of problems such as difficulty sustaining attention, hyperactivity and impulsive behavior, consultations to complete extensive background forms and analysis. By offering incentives and stressing the importance of being prepared for the first consultation, clinicians were able to boost parent and teacher compliance from 25 to 90 percent at the Mayo Clinic Child and Adolescent ADHD Clinic. As a result, researchers have been able to better recommend treatment and therapy right off the bat. "I'd compare treating a child with ADHD for the first time to consulting with someone who has type II diabetes -- we need to measure a diabetic patient's blood sugar level before we can properly treat them," says study lead author Jyoti Bhagia, M.D., a Mayo Clinic psychiatrist . "The same goes for ADHD. The more we kno...

Concern has been raised about inappropriate prescribing of psychotropic medication s to children and adolescents, but these criticisms have been based on anecdotal reports, studies of small unrepresentative clinical samples and secondary analyses of large databases on prescription drug use that lacked clinical information, the authors write in the study background. The study by Kathleen R. Merikangas, Ph.D., of the National Institute of Mental Health, Bethesda, Md., and colleagues evaluated the prevalence, demographic and clinical correlates, and specificity of classes of psychotropic medications indicated for mental disorders. The study involved 10,123 adolescents (ages 13 to 18 years) who participated in the National Comorbidity Survey Adolescent Supplement between February 2001 and January 2004. Researchers examined mental and neurodevelopmental disorders from the  Diagnostic and Statistical Manual of Mental Disorders Fourth Edition ( DSM-IV ). "Among those with any...

A substantial number of children being treated for ADHD may not have the disorder, while many children who do have the symptoms are going untreated, according to the 10-year Project to Learn about ADHD in Youth (PLAY) study funded by the National Center on Birth Defects and Developmental Disabilities of the Centers of Disease Control and Prevention "Childhood ADHD is a major public health problem. Many studies rely on parent reporting of an ADHD diagnosis, which is a function of both the child's access to care in order to be diagnosed, and the parent's perception that there is a problem," said Robert McKeown, of the University of South Carolina's Arnold School of Public Health, who led the South Carolina portion of the study. "Further complicating our understanding of the prevalence of ADHD and its treatment is that the diagnosis often is made by a clinician who has little experience assessing and diagnosing mental disorders. As a result, ADHD is both...

Childhood ADHD and subsequent smoking in adulthood frequently go hand in hand, say the authors, with people who have been diagnosed with ADHD more likely to start smoking early and to smoke twice as much as those without the condition. The researchers focused on five variations in DNA sequences (single nucleotide polymorphisms or SNPs) in different genes that are strongly associated with different aspects of smoking behaviour, such as the number of cigarettes smoked every day, and taking up and quitting smoking. They wanted to see if these might also be linked to hyperactivity in 454 children aged between 6 and 12 with confirmed ADHD and referred to specialist treatment centres. They quizzed the children's mothers about their smoking habits during pregnancy. Of those 394 mothers for whom they had information, 171 had smoked during pregnancy and 223 had not. And they assessed the extent of the children's behavioural and emotional problems at home and at school, as we...

The new research results have been published in the  Journal of Neurophysiology. In Denmark approximately 2-3 per cent of school-age children satisfy diagnostic criteria for ADHD , and therefore it is crucial to know how the medicine works. With a new mathematical reconstruction of a tiny part of the brain region that registers reward and punishment, scientists from the University of Copenhagen are acquiring new knowledge about the effect of ADHD medicine. When reward and punishment signals run through the brain, the chemical dopamine is always involved. "It has been discussed for years whether treating ADHD with Ritalin and similar drugs affects the reward system to any significant degree, simply because the dosage given to patients is so low. We are the first to show that some components of the dopamine signalling pathways are extremely sensitive to drugs like Ritalin. We have also developed a unified theory to describe the effect of such drugs on the dopamine signal,...

While previous research has shown that people with ADHD are more likely to enter a life of crime, it has remained uncertain how ADHD medication affects this risk. After having studied over 25,000 individuals with ADHD from different registries over a four-year period (2006-2009), researchers at Karolinska Institutet have now been able to examine the link between ADHD medication and criminality. The study demonstrates in a variety of ways links between ADHD medication and a reduced risk of criminality. For example, the incidence of criminal behaviour was lower amongst medicated individuals than unmedicated ones; and in the same individual comparing periods of medication with no medication, they also found that ADHD drugs were associated with a significant risk reduction of 32 per cent. This way of studying the same individual is a particular strength in that it shows that the risk reduction is probably not attributable to differences between participants on medication and those not...
