Free fatty acid supplementation and artificial food color exclusions appear to have beneficial effects on ADHD symptoms, although the effect of the former are small and those of the latter may be limited to ADHD patients with food sensitivities...
Early results with structural MRI show thinning of the cerebral cortex in ADHD subjects compared with age-matched controls in prefrontal cortex and posterior parietal cortex, areas involved in working memory and attention.
supervised use of stimulants at therapeutic doses may decrease risk of experimentation with drugs to self-medicate symptoms. Second, untreated ADHD may lead to school failure, peer rejection, and subsequent association with deviant peer groups that encourage drug misuse. ... amphetamines and methylphenidate are used in low doses to treat attention deficit hyperactivity disorder and in higher doses to treat narcolepsy (Chapter 12). Despite their clinical uses, these drugs are strongly reinforcing, and their long-term use at high doses is linked with potential addiction
Mental diseases are invented and then given a name, for example attention deficit hyperactivity disorder (ADHD).
Deciding if a child has ADHD is a several-step process. This page gives you an overview of how ADHD is diagnosed. There is no single test to diagnose ADHD, and many other problems, like sleep disorders, anxiety, depression, and certain types of learning disabilities, can have similar symptoms.
「台灣對這個疾病的知識不足,網路民間常流竄1-20年前過時的資料,而真正接受過此疾病診斷及整合式治療訓練的專科醫師如兒心科醫師又少之又少。」、「ADHD全世界平均盛行率為7.2%,台灣社區研究為7.5%,而台灣健保資料庫研究顯示只有2.3%接受診斷,1.6%用藥,1%的人接受足夠時間完整的治療,所以可了解有許多人求助無門因而情況日益惡化。 」
Reports indicate that ADHD affects 2.5%–5% of adults in the general population,5–8 compared with 5%–7% of children.9,10 ... However, fewer than 20% of adults with ADHD are currently diagnosed and/or treated by psychiatrists.7,15,16
Up till now, there is no conclusive evidence for a relationship between ADHD and CD. Therefore, it is not advised to perform routine screening of CD when assessing ADHD (and vice versa) or to implement GFD as a standard treatment in ADHD. Nevertheless, the possibility of untreated CD predisposing to ADHD-like behavior should be kept in mind. ... It is possible that in untreated patients with CD, neurologic symptoms such as chronic fatigue, inattention, pain, and headache could predispose patients to ADHD-like behavior (mainly symptoms of inattentive type), which may be alleviated after GFD treatment. (CD: celiac disease; GFD: gluten-free diet)
Despite being the most studied disorder in child psychiatry, the pathophysiology of ADHD remains elusive.
Although there is little direct evidence, changes in trace amines, in particular PE, have been identified as a possible factor for the onset of attention deficit/hyperactivity disorder (ADHD). … Further, amphetamines, which have clinical utility in ADHD, are good ligands at trace amine receptors. Of possible relevance in this aspect is modafanil, which has shown beneficial effects in ADHD patients and has been reported to enhance the activity of PE at TAAR1. Conversely, methylphenidate, …showed poor efficacy at the TAAR1 receptor. In this respect it is worth noting that the enhancement of functioning at TAAR1 seen with modafanil was not a result of a direct interaction with TAAR1.

an elimination diet produces a small aggregate effect but may have greater benefit among some children. Very few studies enable proper evaluation of the likelihood of response in children with ADHD who are not already preselected based on prior diet response.
Recent conceptualizations of ADHD have taken seriously the distributed nature of neuronal processing [10,11,35,36]. Most of the candidate networks have focused on prefrontal-striatal-cerebellar circuits, although other posterior regions are also being proposed [10].
The selective norepinephrine (NE) transporter inhibitor atomoxetine (formerly called tomoxetine or LY139603) has been shown to alleviate symptoms in Attention Deficit/Hyperactivity Disorder (ADHD).
Although a substantial amount of research has focused on dopamine (DA) and norepinephrine (NE), ADHD has also been linked to dysfunction in serotonin (5hydroxytryptamine [5-HT]), acetylcholine (ACH), opioid, and glutamate (GLU) pathways (Cortese, 2012; Maltezos et al., 2014; Blum et al., 2008; Potter et al., 2014; Elia et al., 2011). The alterations in these neurotransmitter systems affect the function of brain structures that moderate executive function, working memory, emotional regulation, and reward processing (Fig. 1) (Faraone et al., 2015).
Behavioral studies show altered processing of reinforcement and incentives in children with ADHD. These children respond more impulsively to rewards and choose small, immediate rewards over larger, delayed incentives. Interestingly, a high intensity of reinforcement is effective in improving task performance in children with ADHD. Pharmacotherapy may also improve task persistence in these children. ... Previous studies suggest that a clinical approach using interventions to improve motivational processes in patients with ADHD may improve outcomes as children with ADHD transition into adolescence and adulthood.
Beneficial chronic effects of cardio exercise were found on various functions as well, including executive functions, attention and behavior.
We may conclude that all different types of exercise ... attenuate the characteristic symptoms of ADHD and improve social behaviour, motor skills, strength and neuropsychological parameters without any undesirable side effects. Available reports do not reveal which type, intensity, duration and frequency of exercise is most effective
The findings from these studies provide some support for the notion that exercise has the potential to act as a protective factor for ADHD.
Results suggest there is moderate-to-high-level evidence that combined pharmacological and behavioral interventions, and pharmacological interventions alone can be effective in managing the core ADHD symptoms and academic performance at 14 months. However, the effect size may decrease beyond this period. ... There is high level evidence suggesting that pharmacological treatment can have a major beneficial effect on the core symptoms of ADHD (hyperactivity, inattention, and impulsivity) in approximately 80% of cases compared with placebo controls, in the short term.22
In addition, a consensus has not been reached on the optimal diagnostic criteria for ADHD. Moreover, the benefits and long-term effects of medical and complementary therapies for this disorder continue to be debated. These gaps in knowledge hinder the ability of clinicians to effectively recognize and treat ADHD.
Basal ganglia regions like the right globus pallidus, the right putamen, and the nucleus caudatus are structurally affected in children with ADHD. These changes and alterations in limbic regions like ACC and amygdala are more pronounced in non-treated populations and seem to diminish over time from child to adulthood. Treatment seems to have positive effects on brain structure.
A minority of individuals who use amphetamines develop full-blown psychosis requiring care at emergency departments or psychiatric hospitals. In such cases, symptoms of amphetamine psychosis commonly include paranoid and persecutory delusions as well as auditory and visual hallucinations in the presence of extreme agitation. More common (about 18%) is for frequent amphetamine users to report psychotic symptoms that are sub-clinical and that do not require high-intensity intervention ...
About 5–15% of the users who develop an amphetamine psychosis fail to recover completely (Hofmann 1983) ...
Findings from one trial indicate use of antipsychotic medications effectively resolves symptoms of acute amphetamine psychosis.
Zinc binds at ... extracellular sites of the DAT [103], serving as a DAT inhibitor. In this context, controlled double-blind studies in children are of interest, which showed positive effects of zinc [supplementation] on symptoms of ADHD [105,106]. It should be stated that at this time [supplementation] with zinc is not integrated in any ADHD treatment algorithm.
Attention-deficit hyperactivity disorder (ADHD) is the most common developmental disorder of childhood, affecting approximately 3–9% of schoolchildren [1,2].
7.2% (95% confidence interval: 6.7 to 7.8)
In the National Comorbidity Survey Replication, 4.4% of 3199 subjects aged 18 to 44 years met the DSM-IV criteria for ADHD (Kessler et al., 2006). The acceptance of ADHD symptoms in adults, because the prevalence rates of ADHD in Korean school-age children are similar to the rates reported in Western countries (Kim, 2002).
Although there is little direct evidence, changes in trace amines, in particular PE, have been identified as a possible factor for the onset of attention deficit/hyperactivity disorder (ADHD). … Further, amphetamines, which have clinical utility in ADHD, are good ligands at trace amine receptors.

Japan reports a 7% of school-aged children have ADD/ADHD.
Treatment-emergent psychotic or manic symptoms, e.g., hallucinations, delusional thinking, or mania in children and adolescents without prior history of psychotic illness or mania can be caused by stimulants at usual doses. ... In a pooled analysis of multiple short-term, placebo controlled studies, such symptoms occurred in about 0.1% (4 patients with events out of 3482 exposed to methylphenidate or amphetamine for several weeks at usual doses) of stimulant-treated patients compared to 0 in placebo-treated patients.
Hyperactivity is often considered more of a problem for schools and parents than it is for the child. But many hyperactive children are unhappy, or even depressed. Hyperactive behavior may make a child a target for bullying, or make it harder to connect with other children. Schoolwork may be more difficult. Kids who are hyperactive are frequently punished for their behavior. Excessive movement (hyperkinetic behavior) often decreases as the child grows older. It may disappear entirely by adolescence.

Still, too few with disorder receive behavior therapy, child psychologist says.
As most treatment guidelines and prescribing information for stimulant medications relate to experience in school-aged children, prescribed doses for older patients are lacking. Emerging evidence for both methylphenidate and Adderall indicate that when weight-corrected daily doses, equipotent with those used in the treatment of younger patients, are used to treat adults with ADHD, these patients show a very robust clinical response consistent with that observed in pediatric studies. These data suggest that older patients may require a more aggressive approach in terms of dosing, based on the same target dosage ranges that have already been established – for methylphenidate, 1–1.5–2 mg/kg/day, and for D,L-amphetamine, 0.5–0.75–1 mg/kg/day....
In particular, adolescents and adults are vulnerable to underdosing, and are thus at potential risk of failing to receive adequate dosage levels. As with all therapeutic agents, the efficacy and safety of stimulant medications should always guide prescribing behavior: careful dosage titration of the selected stimulant product should help to ensure that each patient with ADHD receives an adequate dose, so that the clinical benefits of therapy can be fully attained.

An estimated 40 to 60 percent of people with ASD have attention deficit hyperactivity disorder (ADHD), which encompasses such symptoms as difficulty paying attention, problems controlling behavior and hyperactivity. Co-investigators Geraldine Dawson, Ph.D., and Scott Kollins, Ph.D., aim to learn how ADHD may influence the diagnosis and treatment of autism and plan to observe children who have ASD alone, ASD and ADHD, and ADHD alone and compare them to typically developing children. They will also test whether the stimulant medication used to treat ADHD will help children with both conditions.
