4 94 Extreme premature birth, very low birth weight, and extreme neglect, abuse, or social deprivation also increase the risk 4 95 as do certain infections during pregnancy, at birth, and in early childhood. These infections include, among others, various viruses ( measles, varicella zoster encephalitis, rubella, enterovirus 71 ). 96 There is an association between long term but not short term use of acetaminophen during pregnancy and adhd. 97 98 At least 30 of children with a traumatic brain injury later develop adhd 99 and about 5 of cases are due to brain damage. 100 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, 4 101 but the evidence is weak and may only apply to children with food sensitivities. The United Kingdom and the european Union have put in place regulatory measures based on these concerns. 104 In a minority of children, intolerances or allergies to certain foods may worsen adhd symptoms. 105 Research does not support popular beliefs that adhd is caused by eating too much refined sugar, watching too much television, parenting, poverty or family chaos; however, they might worsen adhd symptoms in certain people.

85 Some have hypothesized that some women may be store more attracted to males who are risk takers, increasing the frequency of genes that predispose to hyperactivity and impulsivity in the gene pool. 86 Others have claimed that these traits may be an adaptation that help males face stressful or dangerous environments with, for example, increased impulsivity and exploratory behavior. 85 86 In certain situations, adhd traits may have been beneficial to society as a whole even while being harmful to the individual. The high rates and heterogeneity of adhd may have increased reproductive pdf fitness and benefited society by adding diversity to the gene pool despite being detrimental to the individual. 87 In certain environments, some adhd traits may have offered personal advantages to individuals, such as quicker response to predators or superior hunting skills. 88 people with Down syndrome are more likely to have adhd. 89 Environment edit see also: diet and attention deficit hyperactivity disorder In addition to genetics, some environmental factors might play a role in causing adhd. 90 Alcohol intake during pregnancy can cause fetal alcohol spectrum disorders which can include adhd or symptoms like. 91 Children exposed to certain toxic substances, such as lead or polychlorinated biphenyls, may develop problems which resemble adhd. 4 92 Exposure to the organophosphate insecticides chlorpyrifos and dialkyl phosphate is associated with an increased risk; however, the evidence is not conclusive. 93 Exposure to tobacco smoke during pregnancy can cause problems with central nervous system development and can increase the risk of adhd.
79 80 Those involved with dopamine include dat, drd4, drd5, taar1, maoa, comt, and about dbh. Other genes associated with adhd include sert, htr1b, snap25, grin2a, adra2a, tph2, and bdnf. 79 80 A common variant of a gene called lphn3 is estimated to be responsible for about 9 of cases and when this variant is present, people are particularly responsive to stimulant medication. 83 The 7 repeat variant of dopamine receptor D4 (DRD47R) causes increased inhibitory effects induced by dopamine and is associated with adhd. The drd4 receptor is a g protein-coupled receptor that inhibits adenylyl cyclase. The drd47R mutation results in a wide range of behavioral phenotypes, including adhd symptoms reflecting split attention. 84 evolution may have played a role in the high rates of adhd, particularly hyperactive and impulsive traits in males.
71 In studies of adhd, higher IQs may be over represented because many studies exclude individuals who have lower IQs despite those with business adhd scoring on average nine points lower on standardized intelligence measures. 72 Most adhd cases are of unknown causes. 73 74 It is believed to involve interactions between genetics, the environment, and social factors. 73 74 Certain cases are related to previous infection of or trauma to the brain. 73 Genetics edit Twin studies indicate that the disorder is often inherited from one's parents with genetics determining about 75 of cases. Siblings of children with adhd are three to four times more likely to develop the disorder than siblings of children without the disorder. 77 Genetic factors are also believed to be involved in determining whether adhd persists into adulthood. 78 Typically, a number of genes are involved, many of which directly affect dopamine neurotransmission.
63 mood disorders (especially bipolar disorder and major depressive disorder ). Boys diagnosed with the combined adhd subtype are more likely to have a mood disorder. 50 Adults with adhd sometimes also have bipolar disorder, which requires careful assessment to accurately diagnose and treat both conditions. 64 Restless legs syndrome has been found to be more common in those with adhd and is often due to iron deficiency anaemia. 65 66 However, restless legs can simply be a part of adhd and requires careful assessment to differentiate between the two disorders. 67 people with adhd have an increased risk of persistent bed wetting. 68 A 2016 systematic review found a well established association between adhd and obesity, asthma and sleep disorders, and tentative evidence for association with celiac disease and migraine, 69 while another 2016 systematic review did not support a clear link between celiac disease and adhd. 70 Intelligence edit overall, studies have shown that people with adhd tend to have lower scores on intelligence"ent (IQ) tests. 71 The significance of this is controversial due to the differences between people with adhd and the difficulty determining the influence of symptoms, such as distractibility, on lower scores rather than intellectual capacity.
What does, handwriting, say about, adhd?
53 54 Sleep disorders and adhd commonly co-exist. They can also occur as a side effect of medications used to treat resume adhd. In children with adhd, insomnia is the most common sleep disorder with behavioral therapy the preferred treatment. 55 56 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. 57 Melatonin is sometimes used in children who have sleep onset insomnia. 58 Oppositional defiant disorder (ODD) and conduct disorder (cd which occur with adhd in about 50 and 20 of cases respectively.
59 They are characterized by antisocial behaviors such paper as stubbornness, aggression, frequent temper tantrums, deceitfulness, lying, and stealing. 52 About half of those with hyperactivity and odd or cd develop antisocial personality disorder in adulthood. 60 Brain imaging supports that conduct disorder and adhd are separate conditions. 61 Primary disorder of vigilance, which is characterized by poor attention and concentration, as well as difficulties staying awake. These children tend to fidget, yawn and stretch and appear to be hyperactive in order to remain alert and active. 62 Sluggish cognitive tempo (SCT) is a cluster of symptoms that potentially comprises another attention disorder. It may occur in 3050 of adhd cases, regardless of the subtype.
44 Difficulties managing anger are more common in children with adhd 45 as are poor handwriting 46 and delays in speech, language and motor development. 47 48 Although it causes significant difficulty, many children with adhd have an attention span equal to or better than that of other children for tasks and subjects they find interesting. 12 Associated disorders edit In children, adhd occurs with other disorders about two-thirds of the time. 12 Some commonly associated conditions include: Epilepsy 49 tourette's syndrome 49 Autistic spectrum disorder (asd this disorder affects social skills, ability to communicate, behaviour, and interests. 49 Anxiety disorders have been found to occur more commonly in the adhd population. 50 learning disabilities have been found to occur in about 2030 of children with adhd.
Learning disabilities can include developmental speech and language disorders and academic skills disorders. 51 adhd, however, is not considered a learning disability, but it very frequently causes academic difficulties. 51 Obsessive-compulsive disorder (OCD) can co-occur with adhd and shares many of its characteristics. 52 Substance use disorders. Adolescents and adults with adhd are at increased risk of substance abuse. 19 This is most commonly seen with alcohol or cannabis. 19 The reason for this may be an altered reward pathway in the brains of adhd individuals. 19 This makes the evaluation and treatment of adhd more difficult, with serious substance misuse problems usually treated first due to their greater risks.

2 41 A child with adhd inattentive type has most or all of following symptoms, excluding situations where these symptoms are better explained assignment by another psychiatric or medical condition: 2 42 be easily distracted, miss details, forget things, and frequently switch from one activity. 43 Symptoms of hyperactivity tend to go away with age and turn into "inner restlessness" in teens and adults with adhd. 19 people with adhd of all ages are more likely to have problems with social skills, such as social interaction and forming and maintaining friendships. This entry is true for all subtypes. About half of children and adolescents with adhd experience social rejection by their peers compared to 1015 of non-adhd children and adolescents. People with attention deficits are prone to having difficulty processing verbal and nonverbal language which can negatively affect social interaction. They also may drift off during conversations, miss social cues, and have trouble learning social skills.
Topics include adhd's causes and the use of stimulant medications in its treatment. 32 Most healthcare providers accept adhd as a genuine disorder in children and adults, and the debate in the scientific community mainly centers on how it is diagnosed and treated. The condition was officially known as attention-deficit disorder ( add ) from 1980 to immigration 1987, while before this it was known as hyperkinetic reaction of childhood. 36 37 Contents Signs and symptoms edit adhd symptoms 38 Inattention Hyperactivity-impulsivity gives no close attention to details has trouble focusing on tasks even when trying very hard to has trouble organizing even simple tasks loses things necessary for tasks appears forgetful in daily activities. 39 40 Academic difficulties are frequent as are problems with relationships. 39 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. 41 According to the fifth version 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 2 and they must cause significant. 2 The full criteria must have been met prior to age twelve in order to receive a diagnosis of adhd. 2 adhd is divided into three subtypes: predominantly inattentive (adhd-pi or adhd-i predominantly hyperactive-impulsive (adhd-ph or adhd-hi and combined type (adhd-c).
considered in those with moderate symptoms who either refuse or fail to improve with counseling, though for adults medications are a first-line treatment. 22 Canadian and American guidelines recommend that medications and behavioral therapy be used together as a first-line therapy, except in preschool-aged children. 23 24 Stimulant medication therapy is not recommended as a first-line therapy in preschool-aged children in either guideline. 22 24 Treatment with stimulants is effective for up to 14 months; however, its long term effectiveness is unclear. Adolescents and adults tend to develop coping skills which make up for some or all of their impairments. 29 The medical literature has described symptoms similar to those of adhd since the 19th century. 30 adhd, its diagnosis, and its treatment have been considered controversial since the 1970s. 31 The controversies have involved clinicians, teachers, policymakers, parents, and the media.
12, despite being the most commonly studied and diagnosed mental supermarket disorder in children and adolescents, the exact cause is unknown in the majority of cases. It affects about 57 of children when diagnosed via the. Dsm-iv criteria 13 2 and 12 when diagnosed via the. 14, as of 2015 it is estimated to affect about.1 million people globally. 8, rates are similar between countries and depend mostly on how it is diagnosed. 15, adhd is diagnosed approximately three times more often in boys than in girls, although the disorder is often overlooked in girls because their symptoms differ from those of boys. 16 17 of people diagnosed in childhood continue to have symptoms into adulthood and between 25 of adults have the condition. The condition can be difficult to tell apart from other conditions, as well as to distinguish from high levels of activity that are still within the range of normative behaviors.

Mental disorder with impulsive behavior, difficulty focusing, or excessive activity. Attention-deficit hyperactivity disorder adhd ) is a mental disorder of the neurodevelopmental type. 9 10, it is characterized by problems paying attention, excessive activity, or difficulty controlling behavior which is not appropriate for a person's age. 1 2, the symptoms appear before a person is twelve years old, are present for more than six months, and cause problems in business at least two settings (such as school, home, or recreational activities). 3 11, in children, problems paying attention may result in poor school performance. 1, although it causes impairment, particularly in modern society, many children with adhd have a good attention span for tasks they find interesting.
