[79] In individuals with high intelligence, there is increased risk of a missed ADHD diagnosis, possibly because of compensatory strategies in highly intelligent individuals. [30][31][32] For children and adolescents older than 5, treatment with stimulants is effective for at least 24 months;[33] however, their long-term effectiveness is unclear and there are potentially serious side effects. [34] Careful monitoring of children while taking this medication is recommended. [27], Some ADHD symptoms in adults differ from those seen in children. [46][47] Academic difficulties are frequent as are problems with relationships. [1][23] Currently, most adults remain untreated. [116], Some studies suggest that in a small number of children, artificial food dyes or preservatives may be associated with an increased prevalence of ADHD or ADHD-like symptoms,[12][117] but the evidence is weak and may only apply to children with food sensitivities. [148], Diagnosis of ADHD using quantitative electroencephalography (QEEG) is an ongoing area of investigation, although the value of QEEG in ADHD is currently unclear. [46] The symptoms can be difficult to define, as it is hard to draw a line at where normal levels of inattention, hyperactivity, and impulsivity end and significant levels requiring interventions begin. The genetics of attention deficit/hyperactivity disorder in adults, a review. ADHD is generally the result of neurological dysfunction, more specifically, processes related to the production and use of dopamine in the brain. [48], According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), symptoms must be present for six months or more to a degree that is much greater than others of the same age[1] and they must cause significant problems functioning in at least two settings (e.g., social, school/work, or home).

[208] Chronic deficiencies of iron, magnesium and iodine may have a negative impact on ADHD symptoms. [38][179] They improve symptoms in 80% of people, although improvement is not sustained if medication is ceased. [136] Current models involve the mesocorticolimbic dopamine pathway and the locus coeruleus-noradrenergic system. [205][206][207] In particular, the long-term effects of regular aerobic exercise in ADHD individuals include better behavior and motor abilities, improved executive functions (including attention, inhibitory control, and planning, among other cognitive domains), faster information processing speed, and better memory. [151] The approved test uses the ratio of EEG theta to beta activity to guide diagnosis; however, at least five studies have failed to replicate the finding. [232][233], Until the 1990s, many studies "implicated the prefrontal-striatal network as being smaller in children with ADHD". [188][189][190] Administration of an antipsychotic medication has been found to effectively resolve the symptoms of acute amphetamine psychosis. [1][236], ADHD, its diagnosis, and its treatment have been controversial since the 1970s. ADHD is divided into subtypes—children just with attention problems, those with impulse control and hyperactivity issues, and a group with a combination of the two.

People with attention deficit hyperactivity disorder (ADHD) often say their brains are different from those of people without the disorder—and studies suggest that that's true, says Stephen V. Faraone, PhD, distinguished professor and vice chair for research in the department of psychiatry at SUNY Upstate Medical University in Syracuse, NY.

[235] ADHD was split into the current three sub-types because of a field trial completed by Lahey and colleagues. [242] Some sociologists consider ADHD to be an example of the medicalization of deviant behavior, that is, the turning of the previously non-medical issue of school performance into a medical one. [33] A 2014 review found that an elimination diet results in a small overall benefit in a minority of children, such as those with allergies.

The role of attention came to the fore as a new theory proposed that problems in sustaining attention were the drivers of hyperactivity.
