The criteria must have been met prior to age twelve in order to receive a diagnosis of ADHD. , In addition to genetics, some environmental factors might play a role in causing ADHD. , Current models of ADHD suggest that it is associated with functional impairments in some of the brain's neurotransmitter systems, particularly those involving dopamine and norepinephrine. Otherwise, the disorder is classified as disturbance of activity and attention, other hyperkinetic disorders or hyperkinetic disorders, unspecified. Mindfulness is a receptive attention to present experience.  When diagnosed via the ICD-10 criteria rates in this age group are estimated at 1–2%.  However, zinc supplementation may reduce the minimum effective dose of amphetamine when it is used with amphetamine for the treatment of ADHD.

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. , The management of ADHD typically involves counseling or medications either alone or in combination.  Administration of an antipsychotic medication has been found to effectively resolve the symptoms of acute amphetamine psychosis. In contrast, ADHD has more marked impairments in working memory (Digit Span Test) and verbal fluency (“say as many words that begin with the letter S as you can in one minute”). CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website.

The posterior parietal cortex also shows thinning in individuals with ADHD compared to controls.  They improve symptoms in 80% of people, although improvement is not sustained if medication is ceased. , Diagnosis of ADHD using quantitative electroencephalography (QEEG) is an ongoing area of investigation, although the value of QEEG in ADHD is currently unclear. , In order for genetic variation to be used as a tool for diagnosis, more validating studies need to be performed. If symptoms persist, then parent-training, medication, or psychotherapy (especially cognitive behavioral therapy) can be recommended based on age. These disorders can also sometimes occur along with ADHD. A 2016 systematic review found a well established association between ADHD and obesity. , Guidelines on when to use medications vary by country.

Additionally, it is classified as a disruptive behavior disorder along with ODD, CD, and antisocial personality disorder.  The 7 repeat variant of dopamine receptor D4 (DRD4–7R) causes increased inhibitory effects induced by dopamine and is associated with ADHD.  Electroencephalography (EEG) is not accurate enough to make the diagnosis.  There are no good studies comparing the various medications; however, they appear more or less equal with respect to side effects. However, some people never completely outgrow their ADHD symptoms.  The United Kingdom and the European Union have put in place regulatory measures based on these concerns.  ADHD was split into the current three sub-types because of a field trial completed by Lahey and colleagues.

Attention deficit hyperactivity disorder (ADHD) is a brain disorder that affects how you pay attention, sit still, and control your behavior.  The dopamine and norepinephrine pathways that originate in the ventral tegmental area and locus coeruleus project to diverse regions of the brain and govern a variety of cognitive processes.  This review also found that evidence does not support removing other foods from the diet to treat ADHD.  People with ADHD are more interested in entrepreneurship, and have some traits which are useful to entrepreneurial skills: curiosity, openness to experience, impulsivity, risk-taking, and hyper-focus.  Although very rare, at therapeutic doses these events appear to occur in approximately 0.1% of individuals within the first several weeks after starting amphetamine therapy.  Academic difficulties are frequent as are problems with relationships. , With widely differing rates of diagnosis across countries, states within countries, races, and ethnicities, some suspect factors other than the presence of the symptoms of ADHD are playing a role in diagnosis. Questioning parents or guardians as to how the person behaved and developed as a child may form part of the assessment; a family history of ADHD also adds weight to a diagnosis.

A 2017 review showed that a few-foods elimination diet may help children too young to be medicated or not responding to medication, while free fatty acid supplementation or decreased eating of artificial food coloring as standard ADHD treatment is not advised. ASD shows genetic overlap with ADHD at both common and rare levels of genetic variation. , Previously it was thought that the elevated number of dopamine transporters in people with ADHD was part of the pathophysiology but it appears that the elevated numbers are due to adaptation to exposure to stimulants. Other conditions that should be considered are other neurodevelopmental disorders, tics, and sleep apnea.  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. The latter is sometimes referred to as hyperkinetic syndrome.  Chronic deficiencies of iron, magnesium and iodine may have a negative impact on ADHD symptoms.

The use of stimulants to treat ADHD was first described in 1937. It is a neurodevelopmental disorder because it affects how the brain develops. However, smaller studies have shown that genetic polymorphisms in genes related to catecholaminergic neurotransmission or the SNARE complex of the synapse can reliably predict a person's response to stimulant medication.
