[266] Divergent thinking is the ability to produce creative solutions which differ significantly from each other and consider the issue from multiple perspectives. [22], There is good evidence for the use of behavioral therapies in ADHD. [95], Studies of adults suggest that negative differences in intelligence are not meaningful and may be explained by associated health problems. Takeaways. at home and at school or work). [222] However, zinc supplementation may reduce the minimum effective dose of amphetamine when it is used with amphetamine for the treatment of ADHD. [152] A diagnosis does not imply a neurological disorder. The efficacy of ADDERALL XR in the treatment of ADHD was established on the basis of two controlled trials in children aged 6 to 12, one controlled trial in adolescents aged 13 to 17, and one controlled trial [188][189][190] The safety of these medications in pregnancy is unclear. [2][3] Additionally, several symptoms must have been present before age twelve. This initially causes cortical stimulation and may result in restlessness, excitement, euphoria, garrulousness, and increased motor activity. Study with Quizlet and memorize flashcards containing terms like Psychiatrists and psychologists label behavior as disordered when it is A. aggressive, persistent, and intentional. [159] This difference means using DSM-IV criteria could diagnose ADHD at rates three to four times higher than ICD-10 criteria. [2] Many but not all of these are also common comorbidities of ADHD. These disorders can also sometimes occur along with ADHD. [67] Other psychiatric conditions include reactive attachment disorder,[68] characterised by a severe inability to appropriately relate socially, and sluggish cognitive tempo, a cluster of symptoms that potentially comprises another attention disorder and may occur in 3050% of ADHD cases, regardless of the subtype. [123] Behaviors typical of ADHD occur more commonly in children who have experienced violence and emotional abuse. Other neurodevelopmental conditions are common comorbidities. including alcohol have not been evaluated in clinical studies. The relationship between stress, heart disease and sudden death has been recognized since antiquity. [21], 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, such as cultural norms. Cases of misdiagnosis in ADHD can also occur due to stereotyping of non-caucasian individuals. chlordiazepoxide increases and dopamine decreases sedation. [103] Typically, a number of genes are involved, many of which directly affect dopamine neurotransmission. [252][251], ADHD was split into the current three sub-types because of a field trial completed by Lahey and colleagues. Dysfunction of the dopamine system has been implicated in different nervous system diseases. Since the causes of paradoxical reactions are at least partly genetic, it may be useful in critical situations, for example before operations, to ask whether such abnormalities may also exist in family members. The latter was sometimes referred to as hyperkinetic syndrome. First-generation antipsychotics are dopamine receptor antagonists (DRA) and are known as typical antipsychotics.

[242], Alfred Tredgold proposed an association between brain damage and behavioral or learning problems which was able to be validated by the encephalitis lethargica epidemic from 1917 through 1928. [90], Certain studies have found that people with ADHD tend to have lower scores on intelligence quotient (IQ) tests. [100][101] The siblings of children with ADHD are three to four times more likely to develop the disorder than siblings of children without the disorder. [42], The social construct theory of ADHD suggests that, because the boundaries between normal and abnormal behavior are socially constructed (i.e. When a psychoactive drug enters the user's body, it induces an intoxicating effect. [69] Individuals with ADHD are 4x more likely to develop and be diagnosed with an eating disorder (Anorexia, Bulimia, Binge Eating, ARFID) compared to those without ADHD. [64] Delayed sleep phase disorder is also a common comorbidity of those with ADHD. Children who were born at the last 3 days of a calendar year were reported to have significantly higher levels of diagnosis and treatment for ADHD than children born at the first 3 days of a calendar year. ADHD, predominantly inattentive type, presents with symptoms including being easily distracted, forgetful, daydreaming, disorganization, poor concentration, and difficulty completing tasks. Excessive sex and Light Over-Sensitivity in Retina: Beside inflammation of eyeballs due to excessive prostaglandinE2 and histamine induced by excessive norepinephrine and prolactin, melatonin, melanin, dopamine and glutamate are responsible for visual perception and multilevel regulation of visual sensitivity in response to the intensity of ambient lighting, while the pupil, a For the album, see, "ADD", "ADHD", and "Hyperactive" redirect here. [126] In a minority of children, intolerances or allergies to certain foods may worsen ADHD symptoms.[127]. Social anxiety disorder is known to appear at an early age in most cases. lasmiditan, clonazepam. The incidence of heart attacks and sudden death have been shown to increase significantly following the acute stress of natural disasters like hurricanes, earthquakes and tsunamis and as a consequence of any severe stressor that evokes fight or flight responses. [59][60] Problems with sleep initiation are common among individuals with ADHD but often they will be deep sleepers and have significant difficulty getting up in the morning. ; Repeated, excessive use of alcohol can lead to the development of addiction, which is associated with [1] If the same diagnostic methods are used, the rates are similar between countries. Topics have included causes of ADHD and the use of stimulant medications in its treatment. Often forgets daily activities, or is forgetful while completing them. [197][198] Although potentially addictive at high doses,[199][200] stimulants used to treat ADHD have low potential for abuse. temazepam, sodium oxybate. Boys diagnosed with the combined ADHD subtype are more likely to have a mood disorder. NIMH Pages About Attention-Deficit/Hyperactivity Disorder (ADHD). Frequently interrupts or intrudes, including into others' conversations or activities, or by using people's things without asking. Hormones such as serotonin, glutamate, and dopamine may also be involved. [3], Anxiety and mood disorders are frequent comorbidities. 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. some men suffer from low libido due to a lack of testosterone or dopamine. They are the recommended first-line treatment in those who have mild symptoms or who are preschool-aged. [223], ADHD persists into adulthood in about3050% of cases. [2][3] The symptoms must be present in at least two settings (e.g., social, school, work, or home), and must directly interfere with or reduce quality of functioning. [234] Prior to 1970, it was rare for children to be diagnosed with ADHD, while in the 1970s rates were about 1%. [179], Social skills training, behavioral modification, and medication may have some limited beneficial effects in peer relationships. About half of children and adolescents with ADHD experience social rejection by their peers compared to 1015% of non-ADHD children and adolescents. [213][214][215], Regular physical exercise, particularly aerobic exercise, is an effective add-on treatment for ADHD in children and adults, particularly when combined with stimulant medication (although the best intensity and type of aerobic exercise for improving symptoms are not currently known). Addiction Journal with highest journal impact factor offers Open Access option to meet the needs of authors and [182] Magnetic resonance imaging studies suggest that long-term treatment with amphetamine or methylphenidate decreases abnormalities in brain structure and function found in subjects with ADHD. Lower initial dose: 5 mg PO q6-12hr; adjust gradually based on response and incidence of adverse effects. [39]:6, Worldwide, it is estimated that 2.58% of adults have persistent ADHD (where the individual currently meets the criteria and there is evidence of childhood onset), and 6.76% of adults have symptomatic ADHD (meaning that they currently meet the criteria for ADHD, regardless of childhood onset). Fifty percent of those who develop this disorder have developed it by the age of 11, and 80% have developed it by age 20. ADHD is associated with other neurodevelopmental and mental disorders as well as some non-psychiatric disorders, which can cause additional impairment, especially in modern society. [132][7][134][135] Larger models of ADHD with additional pathways have been proposed. [220] There is a small amount of evidence that lower tissue zinc levels may be associated with ADHD. [112][113] Alcohol intake during pregnancy can cause fetal alcohol spectrum disorders which can include ADHD or symptoms like it. [12][13] Genetic factors play an important role; ADHD tends to run in families and has a heritability rate of 74%. These infections include, among others, various viruses (measles, varicella zoster encephalitis, rubella, enterovirus 71). Other Specified ADHD allows the clinician to describe why the individual does not meet the criteria, whereas Unspecified ADHD is used where the clinician chooses not to describe the reason. [162] Children with ADHD have a higher risk of unintentional injuries. Recreational drug use indicates the use of one or more psychoactive drugs to induce an altered state of consciousness either for pleasure or for some other casual purpose or pastime by modifying the perceptions and emotions of the user. The genes GFOD1 and CDH13 show strong genetic associations with ADHD. A 2013 meta-analysis found less than a third of children with ADHD see some improvement in symptoms with free fatty acid supplementation or decreased eating of artificial food coloring. ADHD symptoms arise from executive dysfunction,[6][7][8] and emotional dysregulation is often considered a core symptom. [227], ADHD is estimated to affect about67% of people aged 18 and under when diagnosed via the DSM-IV criteria. [232][verification needed] As of 2019,[update] it was estimated to affect 84.7 million people globally. J Sex Med. [230] When diagnosed via the ICD-10 criteria, rates in this age group are estimated around12%. Block dopamine receptors, preventing dopamine from stimulating the postsynaptic neurons. INDICATIONS Attention Deficit Hyperactivity Disorder. [219] Chronic deficiencies of iron, magnesium and iodine may have a negative impact on ADHD symptoms. [6], ADHD has also been associated with motivational deficits in children. It is considered less effective than methylphenidate or amphetamine but more so than placebo for children with ADHD. This early age of onset may lead to people with social anxiety disorder being particularly vulnerable to depressive illnesses, substance use, and other psychological conflicts. For other uses, see, Paradoxical reaction to neuroactive substances. [167] It is thus recommended that children with ADHD be regularly assessed for sleep problems. If symptoms persist, parent-training, medication, or psychotherapy (especially cognitive behavioral therapy) can be recommended based on age. [149] In 2014, Keith Conners, one of the early advocates for recognition of the disorder, spoke out against overdiagnosis in a The New York Times article. Symptoms are generally from the following clusters: Meet the criteria for both inattentive and hyperactive-impulsive ADHD. [19] ADHD is alternately classified as neurodevelopmental disorder[151] or a disruptive behavior disorder along with ODD, CD, and antisocial personality disorder. In the United States, these criteria are defined by the American Psychiatric Association in the DSM. [40], Difficulties managing anger are more common in children with ADHD[41] as are delays in speech, language and motor development. Events such as maternal alcohol and tobacco use that affect the development of the fetal brain can increase the risk for ADHD. [25][26][27] Stimulant medications are the most effective pharmaceutical treatment,[28] although there may be side effects[28][29][30][31] and any improvements will be reverted if medication is ceased.[32]. [3], Symptoms of ADHD, such as low mood and poor self-image, mood swings, and irritability, can be confused with dysthymia, cyclothymia or bipolar disorder as well as with borderline personality disorder. [39]:5, For diagnosis in an adult, having symptoms since childhood is required. Frequently has trouble sitting still during dinner, class, in meetings, etc. [61] Specifically, the sleep disorder restless legs syndrome has been found to be more common in those with ADHD and is often due to iron deficiency anemia. [6][133][7][8] Executive functions are a set of cognitive processes that are required to successfully select and monitor behaviors that facilitate the attainment of one's chosen goals. [155], As with many other psychiatric disorders, a formal diagnosis should be made by a qualified professional based on a set number of criteria. [24] Canadian and American guidelines recommend medications and behavioral therapy together, except in preschool-aged children for whom the first-line treatment is behavioral therapy alone. [254][123] Most healthcare providers accept ADHD as a genuine disorder, at least in the small number of people with severe symptoms. [121] At least 30% of children with a traumatic brain injury later develop ADHD[122] and about 5% of cases are due to brain damage. [28] Stimulants may also reduce the risk of unintentional injuries in children with ADHD. ADHD, predominantly hyperactive-impulsive type, presents with excessive fidgeting and restlessness, hyperactivity, and difficulty waiting and remaining seated. [56] Adults and children with ADHD sometimes also have bipolar disorder, which requires careful assessment to accurately diagnose and treat both conditions. sodium oxybate. [104][105] A common variant of a gene called latrophilin 3 is estimated to be responsible for about 9% of cases and when this variant is present, people are particularly responsive to stimulant medication. [108] The 7 repeat variant of dopamine receptor D4 (DRD47R) causes increased inhibitory effects induced by dopamine and is associated with ADHD. [6][7][8] The executive function impairments that occur in ADHD individuals result in problems with staying organised, time keeping, excessive procrastination, maintaining concentration, paying attention, ignoring distractions, regulating emotions, and remembering details. Psychostimulant medication is thought to work by altering the availability of particular brain chemicals or neurotransmitters (dopamine and noradrenaline) in regions of the brain involved with behaviour inhibition, impulse control, attention and working memory. [19] Thomas Szasz, a supporter of this theory, has argued that ADHD was "invented and then given a name". While children with ADHD may climb and run about excessively, adults may experience an inability to relax, or may talk excessively in social situations. [224] Those affected are likely to develop coping mechanisms as they mature, thus compensating to some extent for their previous symptoms. [100] There are multiple gene variants which each slightly increase the likelihood of a person having ADHD; it is polygenic and arises through the combination of many gene variants which each have a small effect. [18][19] This may reflect either a true difference in underlying rate, or that women and girls with ADHD are less likely to be diagnosed. $5000 awarded annually by the Society of Biological Psychiatry! [267] These measurements could potentially serve as diagnostic biomarkers for ADHD, but more research is needed to establish their diagnostic utility. Easily distracted (including by own thoughts); may not listen when spoken to; frequently appears to be lost in thought. Although people with ADHD struggle to focus on tasks they are not particularly interested in completing, they are often able to maintain an unusually prolonged and intense level of attention for tasks they do find interesting or rewarding; this is known as hyperfocus. It is common knowledge that alcohol is often responsible for unexpected one-night stands or other activities. The individual may also meet the criteria for inattention, but the hyperactive-impulsive symptoms are predominant. [39]:13 Evidence supports its ability to improve symptoms when compared to placebo. This part of your brain is also closely linked to memory and motivation. [106][267] Lower urinary phenethylamine concentrations are also associated with symptoms of inattentiveness in ADHD individuals. Attention Deficit Hyperactivity Disorder (ADHD) A diagnosis of Attention Deficit Hyperactivity Disorder (ADHD; DSM-IV ) implies the presence of hyperactive-impulsive or inattentive symptoms that caused impairment and were present before age 7 years.The symptoms must cause clinically significant impairment, e.g., in social, academic, or The effects of physical exercise on cognition and behavior in children and adults with ADHD: a systematic literature review", "Exercise reduces the symptoms of attention-deficit/hyperactivity disorder and improves social behaviour, motor skills, strength and neuropsychological parameters", "Protection from genetic diathesis in attention-deficit/hyperactivity disorder: possible complementary roles of exercise", "Diet and ADHD, Reviewing the Evidence: A Systematic Review of Meta-Analyses of Double-Blind Placebo-Controlled Trials Evaluating the Efficacy of Diet Interventions on the Behavior of Children with ADHD", "Nutritional supplements for the treatment of ADHD", "ADHD and smoking: from genes to brain to behavior", "Attention Deficit Hyperactivity Disorder (ADHD) among longer-term prison inmates is a prevalent, persistent and disabling disorder", "Prevalence of Attention Deficit Hyperactivity Disorder in Detention Settings: A Systematic Review and Meta-Analysis", "State-based Prevalence Data of Parent Reported ADHD", "The prevalence of DSM-IV attention-deficit/hyperactivity disorder: a meta-analytic review", "The worldwide prevalence of ADHD: a systematic review and metaregression analysis", "Problems of overdiagnosis and overprescribing in ADHD: are they legitimate? [133][145] Recent evidence from observational and registry studies indicates that pharmacological treatment of ADHD is associated with increased achievement and decreased absenteeism at school, a reduced risk of trauma-related emergency hospital visits, reduced risks of suicide and attempted suicide, and decreased rates of substance abuse and criminality. In zebrafish, knockout of this gene causes a loss of dopaminergic function in the ventral diencephalon and the fish display a hyperactive/impulsive phenotype. The DRD47R mutation results in a wide range of behavioral phenotypes, including ADHD symptoms reflecting split attention. [140] Current models involve the mesocorticolimbic dopamine pathway and the locus coeruleus-noradrenergic system. ADD is the term commonly used to describe symptoms of inattention, distractibility, and poor working memory. [266] However, people with ADHD may struggle with convergent thinking, which is a cognitive process through which a set of obviously relevant knowledge is utilized in a focused effort to arrive at a single perceived best solution to a problem. Symptoms may not be present when engaged in highly stimulating tasks with frequent rewards. [3], ADHD is divided into three primary presentations:[3][37]. Both are included in the medical diagnosis of attention deficit hyperactivity disorder. [9][39]:6 People with ADHD of all ages are more likely to have problems with social skills, such as social interaction and forming and maintaining friendships. [39]:7,9 While the core symptoms of ADHD are similar in children and adults, they often present differently in adults than in children: for example, excessive physical activity seen in children may present as feelings of restlessness and constant mental activity in adults. Anxiety disorders have been found to occur more commonly in the ADHD population,[56] as have mood disorders (especially bipolar disorder and major depressive disorder). Rather, a number of significant risk factors affecting neurodevelopment and behavior expression have been implicated. [238] Due to ADHD's subjectively determined symptoms, medical professionals may diagnose individuals based on stereotyped behavior or misdiagnose due to differences in symptom presentation between Caucasian and non-Caucasian individuals. Alcohol is dually reinforcing because it can both activate the brains reward processing system that mediates pleasure and reduce the activity of the brains systems that mediate negative emotional states such as stress, anxiety, and emotional pain. [132][133] 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. [228] ADHD is more common among longer-term inmates; a 2010 study at Norrtlje Prison, a high-security prison in Sweden, found an estimated ADHD prevalence of 40%. [132][133][7] ADHD psychostimulants possess treatment efficacy because they increase neurotransmitter activity in these systems. [132][7] 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;[132][133][7] these pathways are known to play a central role in the pathophysiology of ADHD. Environment. The individual is the best source for information in diagnosis, however others may provide useful information about the individual's symptoms currently and in childhood; a family history of ADHD also adds weight to a diagnosis. Catatonia is a complex neuropsychiatric behavioral syndrome that is characterized by abnormal movements, immobility, abnormal behaviors, and withdrawal. [168] Sleepiness in children may result in symptoms ranging from the classic ones of yawning and rubbing the eyes, to hyperactivity and inattentiveness. [28] About 70 percent respond to the first stimulant tried and as few as 10 percent respond to neither amphetamines nor methylphenidate. [266] Those with ADHD symptoms could be advantaged in this form of creativity as they tend to have diffuse attention, allowing rapid switching between aspects of the task under consideration;[266] flexible associative memory, allowing them to remember and use more distantly-related ideas which is associated with creativity; and impulsivity, which causes people with ADHD symptoms to consider ideas which others may not have. [57][58], Sleep disorders and ADHD commonly co-exist. There are many reasons why a person may turn to drugs or alcohol initially, including using these mind-altering substances as a coping mechanism for stress, difficult emotions, physical ailments, and other [133][136] The posterior parietal cortex also shows thinning in individuals with ADHD compared to controls. Either increases effects of the other by pharmacodynamic synergism. Struggles to maintain focus on tasks that aren't highly stimulating/rewarding or that require continuous effort; details are often missed, and careless mistakes are frequent in school and work tasks; tasks are often abandoned before they are completed. [14] Toxins and infections during pregnancy and brain damage may be environmental risks. The sensory overload is treatable with oral potassium gluconate. [25] Medications are especially not recommended for preschool children. [39]:6, Although not listed as an official symptom for this condition, emotional dysregulation or mood lability is generally understood to be a common symptom of ADHD. [264] However, some studies have included subjective ratings from teachers and parents as part of their assessment of ADHD treatment efficacies. [216][217][218] 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. However, the ICD-11 includes two residual categories for individuals who do not entirely match any of the defined subtypes: other specified presentation (6A05.Y) where the clinician includes detail on the individual's presentation; and presentation unspecified (6A05.Z) where the clinician does not provide detail. [202] Pseudoephedrine and ephedrine do not affect ADHD symptoms.[181]. ADHD is often comorbid with disruptive, impulse control, and conduct disorders. [166] 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. [109] The DRD4 gene is both linked to novelty seeking and ADHD. They also have anticholinergic, antihistaminic, and alpha-adrenergic blocking effects, all of which are related to its dopamine-receptor blocking action. Excessive motor activity; struggles to sit still, often leaving their seat; prefers to run about; in younger children, will fidget when attempting to sit still; in adolescents and adults, a sense of physical restlessness or discomfort with being quiet and still. Some hyperactive-impulsive or inattentive symptoms that caused impairment were present before age 7 years. Cortisol, sexual arousal, and affect in response to sexual stimuli. Dopamine is a neurotransmitter that is produced in the substantia nigra, ventral tegmental area, and hypothalamus of the brain. [27][24] [2][3] The symptoms must be inappropriate for a child of that age[2][157][3] and there must be clear evidence that they are causing social, school or work related problems. [216], Dietary modifications are not recommended as of 2019[update] 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. Modafinil has shown some efficacy in reducing the severity of ADHD in children and adolescents.

Symptoms which can be better explained by another psychiatric or medical condition which an individual has are not considered to be a symptom of ADHD for that person. [225] Rates of smoking among those with ADHD are higher than in the general population at about 40%. ADDERALL XR is indicated for the treatment of attention deficit hyperactivity disorder (ADHD).. dopamine. B. Langguth, R. Br, N. Wodarz, M. Wittmann, R. Laufktter: Rainer Laufktter, Berthold Langguth, Monika Johann, Peter Eichhammer, Gran Hajak: "Are We Overdiagnosing and Overtreating ADHD?" Here, we explain its two distinct presentations. [112][124][125] The European Union has put in place regulatory measures based on these concerns. [2][3] To be considered, several symptoms must have appeared by the age of six to twelve and occur in more than one environment (e.g. ASD shows genetic overlap with ADHD at both common and rare levels of genetic variation. [80], Some non-psychiatric conditions are also comorbidities of ADHD. [251] During this same period, a genetic component was identified and ADHD was acknowledged to be a persistent, long-term disorder which lasted from childhood into adulthood. [267], "Attention Deficit" redirects here. The defined subtypes are similar to those of the DSM-5: predominantly inattentive presentation (6A05.0); predominantly hyperactive-impulsive presentation(6A05.1); combined presentation (6A05.2). B. selfish, habitual, and avoidable. , Emily Hirsch, Glenn S. Hirsch, MD. Typically, these tend to be most apparent in environments with structure or which require self-control. This includes epilepsy,[51] a neurological condition characterised by recurrent seizures.

Independent component analysis performed on resting-state fMRI data have revealed that individuals with the inattentive type of ADHD have significantly more independent components are required to describe the variance of this data. [212] This is particularly common in adolescents and adults as approved dosing is based on school-aged children, causing some practitioners to use weight-based or benefit-based off-label dosing instead. [182] Effects of medication on functional impairment and quality of life (e.g. loss of interest in hobbies or regular activities, This page was last edited on 27 November 2022, at 03:56. [206] For children, stimulants appear to improve academic performance while atomoxetine does not. [16][17][18][19] About 3050% of people diagnosed in childhood continue to have ADHD in adulthood, with 2.58% of adults estimated to have ADHD which began in childhood. [93] In studies of ADHD, higher IQs may be over-represented because many studies exclude individuals who have lower IQs despite those with ADHD scoring on average nine points lower on standardized intelligence measures. This highlights the importance of close collaboration between health services to avoid clinical overshadowing. About 4% to 5% of U.S. adults have it.
