which of these is true about attention deficit hyperactivity disorder

[2], Adults with ADHD are diagnosed under the same criteria, including that their signs must have been present by the age of six to twelve. About half of children and adolescents with ADHD experience social rejection by their peers compared to 10–15% of non-ADHD children and adolescents. [17] As of 2019, it was estimated to affect 84.7 million people globally. [241] In contrast, a 2014 peer-reviewed medical literature review indicated that ADHD is under diagnosed in adults. [155] The symptoms must be inappropriate for a child of that age[155][157] and there must be clear evidence that they are causing social, school or work related problems. This is called attention deficit hyperactivity disorder, or ADHD. [99] Rare genetic variants show more relevant clinical significance as their penetrance (the chance of developing the disorder) tends to be much higher. Learn about CDC’s initiative to support children with ADHD. While those findings bring some clarity to the picture, they only hold up when comparing populations. [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. There is a way", "The intersection of attention-deficit/hyperactivity disorder and substance abuse", "Evaluation and diagnosis of attention deficit hyperactivity disorder in children", "Continuity of aggressive antisocial behavior from childhood to adulthood: The question of phenotype definition", "Sluggish cognitive tempo (concentration deficit disorder? [1] The criteria must have been met prior to age twelve in order to receive a diagnosis of ADHD. [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. The clinical presentation and course of the disorder have been extensively characterised. [205] It is believed that these short-term effects of exercise are mediated by an increased abundance of synaptic dopamine and norepinephrine in the brain. [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. [65][129][130] People with ADHD appear to have unimpaired long-term memory, and deficits in long-term recall appear to be attributed to impairments in working memory. [12][108] Exposure to the organophosphate insecticides chlorpyrifos and dialkyl phosphate is associated with an increased risk; however, the evidence is not conclusive. [65][130][140] The executive function impairments that occur in ADHD individuals result in problems with staying organized, time keeping, excessive procrastination, maintaining concentration, paying attention, ignoring distractions, regulating emotions, and remembering details. [134] Inter-hemispheric asymmetries in white matter tracts have also been noted in children with ADHD, suggesting that disruptions in temporal integration may be related to the behavioral characteristics of ADHD. ", "Recent advances in understanding of attention deficit hyperactivity disorder (ADHD): how genetics are shaping our conceptualization of this disorder", "The evolution of hyperactivity, impulsivity and cognitive diversity", "Lead and PCBs as risk factors for attention deficit/hyperactivity disorder", "What causes attention deficit hyperactivity disorder? [113][114] At least 30% of children with a traumatic brain injury later develop ADHD[115] and about 5% of cases are due to brain damage. [205], Dietary modifications are not recommended as of 2019 by the American Academy of Pediatrics, the National Institute for Health and Care Excellence, or the Agency for Healthcare Research and Quality due to insufficient evidence. jointly created and validated by all members of society, and in particular by physicians, parents, teachers, and others) it then follows that subjective valuations and judgements determine which diagnostic criteria are used and, thus, the number of people affected. [93][94][95] Other genes associated with ADHD include SERT, HTR1B, SNAP25, GRIN2A, ADRA2A, TPH2, and BDNF. [149][150] In the United States, the Food and Drug Administration has approved the use of QEEG to evaluate ADHD. [219] Prior to 1970, it was rare for children to be diagnosed with ADHD while in the 1970s rates were about 1%. [38][197] There are no good studies comparing the various medications; however, they appear more or less equal with respect to side effects. [120] A 2016 review stated that the use of a gluten-free diet as standard ADHD treatment is not advised. CDC twenty four seven. [208] Chronic deficiencies of iron, magnesium and iodine may have a negative impact on ADHD symptoms. [128][130] The dopamine pathways and norepinephrine pathways which project to the prefrontal cortex and striatum are directly responsible for modulating executive function (cognitive control of behavior), motivation, reward perception, and motor function;[128][129][130] these pathways are known to play a central role in the pathophysiology of ADHD. As a result, the emergence of any new diagnosis, such as attention-deficit hyperactivity disorder (ADHD), needs to be greeted with caution, rigour and scientific objectivity, as well as compassion, therapeutic engagement and optimism. [29][35] Underdosing of stimulants can occur and result in a lack of response or later loss of effectiveness. [107] Children exposed to certain toxic substances, such as lead or polychlorinated biphenyls, may develop problems which resemble ADHD. [9] Although it causes impairment, particularly in modern society, many people with ADHD can have sustained attention for tasks they find interesting or rewarding (known as hyperfocus). [1][2] In children, problems paying attention may result in poor school performance. 13. [176] ADHD-specific support groups can provide information and may help families cope with ADHD. This is true for all subtypes. Difficulty paying attention (inattention) Being overactive (hyperactivity) Acting without thinking (impulsivity) These symptoms get in the way of functioning or development. [86][87][88] Certain cases are related to previous infection or trauma to the brain. Some individuals with ADHD also display difficulty regulating emotions or problems with executive function. [79] In individuals with high intelligence, there is increased risk of a missed ADHD diagnosis, possibly because of compensatory strategies in highly intelligent individuals. Epub 2020 Jan 11. [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. [181] One study from Denmark found an increased risk of death among those with ADHD due to the increased rate of accidents. [84][85] This is due in part to a number of high-profile entrepreneurs with ADHD. In Zebrafish, knockout of this gene causes a loss of dopaminergic function in the ventral diencephalon and the fish display a hyperactive/impulsive phenotype. Adults with ADHD may start relationships impulsively, display sensation-seeking behavior, and be short-tempered. [161] It is thus recommended that children with ADHD be regularly assessed for sleep problems. [99] Another candidate causative gene that has been identified is adhesion-G protein-coupled-receptor-L3 (ADGRL3). [65], ADHD has also been associated with motivational deficits in children. [27] The condition can be difficult to tell apart from other conditions, as well as from high levels of activity within the range of normal behavior. ADHD stands for Attention Deficit Hyperactivity Disorder, one of the most common disorders in childhood. [136] Current models involve the mesocorticolimbic dopamine pathway and the locus coeruleus-noradrenergic system. [218], Rates of diagnosis and treatment have increased in both the United Kingdom and the United States since the 1970s. [86], Twin studies indicate that the disorder is often inherited from the person's parents, with genetics determining about 75% of cases in children and 35% to potentially 75% of cases in adults. However, some people never completely outgrow their ADHD symptoms. ADHD, combined type is a combination of the first two subtypes. Bonvicini C, Faraone SV, Scassellati C. Attention-deficit hyperactivity disorder in adults: a systematic review and meta-analysis of genetic, pharmacogenetic and biochemical studies. [205][206][207] Parent-teacher ratings of behavioral and socio-emotional outcomes in response to regular aerobic exercise include: better overall function, reduced ADHD symptoms, better self-esteem, reduced levels of anxiety and depression, fewer somatic complaints, better academic and classroom behavior, and improved social behavior.

CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. ADHD is a behavioral disorder, making it difficult to quantify. [35], The social construct theory of ADHD suggests that because the boundaries between "normal" and "abnormal" behavior are socially constructed, (i.e. Learn About Attention-Deficit / Hyperactivity Disorder (ADHD) Español (Spanish) Related Pages. [165] Electroencephalography (EEG) is not accurate enough to make the diagnosis. [16] When diagnosed via the ICD-10 criteria rates in this age group are estimated at 1–2%. [185], The long-term effects of ADHD medication have yet to be fully determined,[186][187] although stimulants are generally beneficial and safe for up to 2 years. [82], In entrepreneurship, there has been interest in the traits of people with ADHD.
