Aetna considers certain services medically necessary for the assessment of attention deficit hyperactivity disorder (ADHD):
Complete psychiatric evaluation (adults)
Electroencephalography (EEG) or neurological consult when the presence of focal signs or clinical findings are suggestive of a seizure disorder or a degenerative neurological condition
Measurement of blood lead level
Medical evaluation (complete medical history and physical examination)
Neuropsychological testing is not considered medically necessary for the clinical evaluation of persons with uncomplicated cases of ADHD. Psychological testing is not considered medically necessary for evaluation of children with uncomplicated cases of ADHD. In addition, neuropsychological or psychological testing performed solely for educational reasons may be excluded from coverage, as many Aetna benefit plans exclude coverage of educational testing; please check benefit plan descriptions. Neuropsychological testing may be medically necessary in neurologically complicated cases of ADHD (e.g., post head trauma, seizures). (See CPB 0158 - Neuropsychological and Psychological Testing).
Referral to an outpatient mental health or chemical dependency provider may be medically necessary for the evaluation and comprehensive bio-psychosocial treatment for these disorders in collaboration with primary care physicians and other specialists.
Aetna considers the following experimental and investigational for the assessment and treatment of ADHD because the peer-reviewed medical literature does not support the use of these procedures/services for this indication.
Coverage of pharmacotherapies is subject to the member's specific benefits for drug coverage. Please check benefit plan descriptions for details.
Many Aetna plans exclude coverage of educational interventions. Please check benefit plan descriptions for details.
Psychotherapy is covered under Aetna mental health benefits if the member also exhibits anxiety and/or depression.
Attention deficit/hyperactivity disorder (ADHD) is a common condition among children and adolescents, and has been diagnosed with increased frequency in adults. It is characterized by symptoms of inattention and/or hyperactivity/impulsivity that have persisted for at least 6 months to a degree that is maladaptive and inconsistent with developmental level. Usually, some symptoms that caused impairment were present before the age of 7 years. Some impairment from the symptoms is present in 2 or more settings (e.g., at home and at school). Other causes of symptoms (e.g., schizophrenia, psychotic disorder, mood disorder, anxiety disorder, or personality disorder) should be ruled out.
There is no specific test for ADHD; its diagnosis is a clinical one. A parent/child interview is the cornerstone in the assessment of ADHD in children and adolescents. It is used to rule out other psychiatric or environmental causes of symptoms. A medical evaluation with a complete medical history and a physical examination is necessary.
According to the American Academy of Child and Adolescent Psychiatry (AACAP)’s Practice Parameter for the Assessment and Treatment of Children and Adolescents with Attention-Deficit/Hyperactivity Disorder, neuropsychological testing of children for the purpose of diagnosing ADHD is not considered necessary, unless there is strong evidence of a possible neurological disorder. There are few medical conditions which present with ADHD-like symptoms and most patients with ADHD have unremarkable medical histories. Neuropsychological assessment may be useful in neurologically-complicated cases of ADHD; however, such testing does not confirm the diagnosis of ADHD.
In general, attention-deficit disorders are best diagnosed through a careful history and the use of structured clinical interviews and dimensionally-based rating scales. Most psychologists obtain behavior ratings at home from the parents and at school from the teacher. Examples of the rating scales commonly used by psychologists are the Achenbach Child Behavior Checklist, Conners Rating Scales, and ADHD Symptoms Rating Scale.
Measurement of blood level of lead is appropriate only if clinical or environmental risk factors are present. Electroencephalography or neurological consult is indicated only in the presence of focal signs or clinical suggestions of seizure disorder or degenerative condition.
There are insufficient data to support the usefulness of computerized EEG (brain mapping or neurometrics), event-related potentials, neuroimaging, computerized tests of attention and vigilance, or neuropsychological tests (e.g., Test of Variables of Attention, the Continuous Performance Task, the Wisconsin Card-Sorting Test, the matching Familiar figures Test, and the Wechsler Intelligence Scale for Children-Revised). However, neuropsychological testing may be required in neurologically complicated cases of ADHD (e.g., post head trauma, seizures). There are no data to support the use of hair analysis or measurement of zinc.
Medical management of ADHD entails the use of stimulants -- methylphenidate (Ritalin), dextroamphetamine (Dexedrine), methamphetamine (Desoxyn), as well as an amphetamine-dextroamphetamine combination (Adderall). Pemoline (Cylert) is restricted to secondary use because of hepatic dysfunction associated with its use. Tricyclic anti-depressants are used for patients who do not respond to stimulants listed above, or for those who develop significant depression or other side effects on stimulants, or for the treatment of ADHD symptoms in patients with tics or Tourette's disorder. Psychotherapy is appropriate patients also exhibit anxiety and/or depression.
In a Cochrane review on the use of amphetamine for ADHD in people with intellectual disabilities (ID), Thomson et al (2009a) concluded that there is very little evidence for the effectiveness of amphetamine for ADHD in people with ID. The use of amphetamine in this population is based on extrapolation of research in people without ID. The authors stated that more research into effectiveness and tolerability is urgentlu needed. Furthermore another Cochrane review discussed the use of risperidone for ADHD in people with ID (Thomson et al, 2009b). The authors concluded that there is no evidence from randomized controlled trials that risperidone is effective for the treatment of ADHD in people with ID. The use of risperidone in this population is based on open-label studies or extrapolation from research in people with autism and disruptive behavioral disorders; however these studies have not investigated people with ID separately so there are reservations regarding the applicability of these findings. Research into effectiveness and tolerability is urgently needed.
There is a lack of scientific evidence to support the use of megavitamin therapy, herbal remedies, cognitive behavior modification, anti-motion-sickness medication, anti-candida-albicans medication, psychopharmaceuticals such as lithium, benzodiazepines, and selective serotonin re-uptake inhibitors, biofeedback, sensory (auditory) integration therapy, optometric vision training/Irlen lenses, chiropractic manipulation, or dietary interventions for the treatment of ADHD.
Konofal et al (2008) studied the effects of iron supplementation on ADHD in children. A total of 23 non-anemic children (aged 5 to 8 years) with serum ferritin levels less than 30 ng/ml who met DSM-IV criteria for ADHD were randomized (3:1 ratio) to either oral iron (ferrous sulfate, 80 mg/day, n = 18) or placebo (n = 5) for 12 weeks. There was a progressive significant decrease in the ADHD Rating Scale after 12 weeks on iron (-11.0 +/- 13.9; p < 0.008), but not on placebo (3.0 +/- 5.7; p = 0.308). Improvement on Conners' Parent Rating Scale (p = 0.055) and Conners' Teacher Rating Scale (p = 0.076) with iron supplementation therapy failed to reach significance. The mean Clinical Global Impression-Severity significantly decreased at 12 weeks (p < 0.01) with iron, without change in the placebo group. The authors concluded that iron supplementation appeared to improve ADHD symptoms in children with low serum ferritin levels suggesting a need for future investigations with larger controlled trials.
The American Academy of Pediatrics (2000) has the following statements regarding the diagnosis and evaluation of patients with ADHD:
Available evidence does not support routine screening of thyroid function as part of the effort to diagnose ADHD.
Current data do not support the use of any available continuous performance tests in the diagnosis of ADHD
Current literature does not support the routine use of EEG in the diagnosis of ADHD.
Neuroimaging studies should not be used as a screening or diagnostic tool for children with ADHD because they are associated with high rates of false-positives and false-negatives.
Regular screening of children for high lead levels does not aid in the diagnosis of ADHD.
Neuropsychological and psychological testing for purely educational reasons are not generally considered medically necessary. This testing is usually provided by school systems under applicable state and federal rules. Neuropsychological testing may be medically necessary in neurologically complicated cases of ADHD (e.g., post head trauma, seizures). Children with uncomplicated ADHD do not require neuropsychological or psychological testing.
Feifel (1996) stated that ADHD may affect up to 3 % of the adult population. Attention deficit hyperactivity disorder is not an acquired disorder of adulthood. Adults who were never diagnosed as having ADHD in childhood may present with many of the symptoms of the disorder. Inattention and distractibility, impulsivity, as well as hyperactivity are the classic hallmarks of ADHD, but adult patients often lack the full symptom complex, especially hyperactivity. Mood-associated symptoms (e.g., low frustration tolerance, irritability) are often present. In this regard, adults with ADHD usually have a difficult time with activities that require passive waiting. Adults with ADHD can be evaluated and successfully treated. Since the diagnosis is a clinical one, a comprehensive interview is the most important diagnostic procedure. A complete psychiatric evaluation with particular attention to the core symptoms of ADHD is essential for assessing ADHD in adults. Childhood history is also extremely important (Wender, 1998).
Wender developed ADHD criteria, known as the Utah criteria, which reflect the distinct features of the disorder in adults (Wender, 1998). The diagnosis of ADHD in an adult requires a longstanding history of ADHD symptoms, dating back to at least age 7. In the absence of treatment, such symptoms should have been consistently present without remission. In addition, hyperactivity and poor concentration should be present in adulthood, along with 2 of the 5 additional symptoms: affective lability; hot temper; inability to complete tasks and disorganization; stress intolerance; and impulsivity.
The same medications used for children with ADHD are effective in adult patients. In a randomized controlled study (n = 146), Spencer et al (2005) concluded that robust doses of methylphenidate (average of 1.1mg/kg body weight/day) are effective in the treatment of adult ADHD. This is in agreement with the findings from a meta-analysis (Faraone et al, 2004) that the degree of efficacy of methylphenidate in treating ADHD adults is similar to what has been reported from meta-analyses of the child and adolescent literature. However, it should be noted that there is limited information regarding the long-term use of stimulants in adults (Kooij et al, 2004).
Kates (2005) noted that pharmacotherapies for patients with adult ADHD include stimulants and antidepressants; and medication can benefit up to 60 % of patients. In a randomized controlled study (n = 162), Wilens et al (2005) concluded that bupropion XL is an effective and well-tolerated non-stimulant treatment for adult ADHD. Adler et al (2005) stated that the results of an interim analysis (97 weeks) of an ongoing, open-label study (n = 384) support the long-term safety, effectiveness, and tolerability of another non-stimulant, atomoxetine, for the treatment of adult ADHD.
In a meta-analysis on the use of EEG biofeedback for the treatment of ADHD, Monastra and colleagues (2005) critically examined the empirical evidence, applying the efficacy guidelines jointly established by the Association for Applied Psychophysiology and Biofeedback (AAPB) and the International Society for Neuronal Regulation (ISNR). On the basis of these scientific principles, EEG biofeedback was deemed to be "probably efficacious" for the treatment of ADHD. Although significant clinical improvement was reported in about 75 % of the patients in each of the published research studies, additional randomized, controlled group studies are needed in order to provide a better estimate of the percentage of patients with ADHD who will demonstrate such gains in clinical practice.
van As and colleagues (2010) stated that neurofeedback is a method of treatment that is being used increasingly in the Netherlands, particularly in psychological practices. Many psychiatric and somatic symptoms are currently being treated with the help of neurofeedback. In particular, neurofeedback is being used more and more to ADHD. Despite its growing popularity, neurofeedback is still a relatively unknown treatment method in psychiatric practices. These investigators examined the scientific evidence for treating ADHD with neurofeedback. They searched the literature for reports on controlled trials that investigated the effectiveness of neurofeedback on ADHD. A total of 6 controlled trials were located. The studies reported that neurofeedback had a positive effect on ADHD, but all the studies were marred by methodological shortcomings. The authors concluded that on the basis of currently available research results, no firm conclusion can be drawn about the effectiveness of treating ADHD by means of neurofeedback. In view of the fact that neurofeedback is being used more and more as a method of treatment, there is an urgent need for scientific research in this field to be well-planned and carefully executed.
Jensen and Kelly (2004) examined the effects of yoga on the attention and behavior of boys with ADHD. Subjects were randomly assigned to a 20-session yoga group (n = 11) or a control group (cooperative activities; n = 8). They were assessed pre- and post-intervention on the Conners' Parent and Teacher Rating Scales-Revised: Long (CPRS-R:L & CTRS-R:L), the Test of Variables of Attention (TOVA), and the Motion Logger Actigraph. Data were analyzed using 1-way repeated measures analysis of variance (ANOVA). Significant improvements from pre-test to post-test were found for the yoga, but not for the control group on 5 subscales of the Conners' Parents Rating Scales (CPRS): Oppositional, Global Index Emotional Lability, Global Index Total, Global Index Restless/Impulsive and ADHD Index. Significant improvements from pre-test to post-test were found for the control group, but not the yoga group on 3 CPRS subscales: Hyperactivity, Anxious/Shy, and Social Problems. Both groups improved significantly on CPRS Perfectionism, DSM-IV Hyperactive/ Impulsive, and DSM-IV Total. For the yoga group, positive change from pre- to post-test on the Conners' Teacher Rating Scales (CTRS) was associated with the number of sessions attended on the DSM-IV Hyperactive-Impulsive subscale and with a trend on DSM-IV Inattentive subscale. Those in the yoga group who engaged in more home practice showed a significant improvement on TOVA Response Time Variability with a trend on the ADHD score, and greater improvements on the CTRS Global Emotional Lability subscale. Results from the Motion Logger Actigraph were inconclusive. The authors noted that although these data did not provide strong support for the use of yoga for ADHD, partly because the study was under-powered, they did suggest that yoga may have merit as a complementary treatment for boys with ADHD already stabilized on medication, particularly for its evening effect when medication effects are absent. They stated that yoga remains an investigational treatment, and this study supported further research into its possible uses for this population. The authors stated that these findings need to be replicated on larger groups with a more intensive supervised practice program.
Working memory (WM) capacity is one's ability to retain and manipulate information during a short period of time. This ability underlies complex reasoning and has generally been regarded as a fixed trait of the individual. Children/adolescents with ADHD represent one group of patients with a WM deficit, attributed to an impairment of the frontal lobe (Martinussen et al, 2005). Cogmed and RoboMemo WM training are software-based approaches designed for children and adolescents with ADHD to improve their ability to concentrate and use problem solving skills after training.
Klingberg and colleagues (2005) conducted a multi-center, randomized, controlled, double-blind study to examine the effect of improving WM by computerized, systematic practice of WM tasks. A total of 53 children with ADHD (9 girls, 44 boys; 15 of 53 inattentive subtype), aged 7 to 12 years, without stimulant medication were included in the study. The compliance criterion (greater than 20 days of training) was met by 44 subjects, 42 of whom were also evaluated at follow-up 3 months later. Participants were randomly assigned to use either the treatment computer program for training WM or a comparison program. The main outcome measure was the span-board task, a visuo-spatial WM task that was not part of the training program. For the span-board task, there was a significant treatment effect both post-intervention and at follow-up. In addition, there were significant effects for secondary outcome tasks measuring verbal WM, response inhibition, and complex reasoning. Parent ratings also showed significant reduction in symptoms of hyperactivity/impulsivity, and inattention, both post-intervention and at follow-up. The authors concluded that the findings of this study show that WM can be improved by training in children with ADHD. This training also improved response inhibition and reasoning and resulted in a reduction of the parent-rated inattentive symptoms of ADHD.
It is interesting to note that improvements with WM training lasted for 3 months following treatment. However, how long these improvements might persist is unclear. Furthermore, whether continued training is needed to maintain these gains over a longer duration has yet to be ascertained. Additionally, this study had several drawbacks: (i) only 9 of 53 subjects in this small study were girls, so that a larger study with more girls is needed to better assess overall efficacy and applicability of this therapy to girls with ADHD; (ii) because individuals with depression and/or co-occurring oppositional defiant disorder were excluded, the extent to which these findings could be extrapolated to children/adolescents with ADHD and these behavioral conditions is unknown. Since many children/adolescents with ADHD also have these conditions, it will be important to determine if WM training is beneficial to these children/adolescents as well; (iii) the absence of teacher-reported improvements is of particular concern. Although these investigators suggested that parental ratings are more reliable because they were consistent with the executive functioning results, the basis for this suggestion is unclear. Since an objective of ADHD therapy is to improve patients' functioning at school, demonstrating that WM training achieves this goal is important.
Preliminary data suggested that computerized training of WM may be an effective treatment for children/adolescents with ADHD. However, more research is needed to establish the effectiveness of this approach.
Rickson (2006) compared the impact of instructional and improvisational music therapy approaches on the level of motor impulsivity displayed by adolescent boys (n = 13) who have ADHD. A combination of a multiple contrasting treatment and an experimental control group design was used. No statistical difference was found between the impact of the contrasting approaches as measured by a Synchronized Tapping Task (STT) and the parent and teacher versions of Conners' Rating Scales Restless-Impulsive (R-I) and Hyperactive-Impulsive (H-I) subscales. The author noted that while no firm conclusions can be drawn, there are indications that the instructional approach may have contributed to a reduction of impulsive and restless behaviors in the classroom. In addition, over the period of the study, both music therapy treatment groups significantly improved accuracy on the STT, and teachers reported a significant reduction in Conners' DSM-IV Total and Global Index subscale scores. The author concluded that these findings tentatively suggested that music therapy may contribute to a reduction in a range of ADHD symptoms in the classroom, and that increasing accuracy on the STT could be related to improvement in a range of developmental areas-not specifically motor impulsivity.
Altunc et al (2007) evaluated the evidence of any type of therapeutic or preventive intervention testing homeopathy for childhood and adolescence ailments. Systematic literature searches were conducted in MEDLINE, EMBASE, AMED, CINAHL, Cochrane Central, British Homeopathic Library, ClinicalTrials.gov, and the UK National Research Register. Bibliographies were checked for further relevant publications. Studies were selected according to pre-defined inclusion and exclusion criteria. All double-blind, placebo-controlled randomized clinical trials of any homeopathic intervention for preventing or treating childhood and adolescence ailments were included. According to the classification of the World Health Organization, the age range defined for inclusion was 0 to 19 years. Study selection, data extraction, and assessment of methodological quality were performed independently by 2 reviewers. A total of 326 articles were identified, 91 of which were retrieved for detailed evaluation. Sixteen trials that assessed 9 different conditions were included in the study. With the exception of ADHD and acute childhood diarrhea (each tested in 3 trials), no condition was evaluated in more than 2 double-blind randomized clinical trials. The evidence for ADHD and acute childhood diarrhea is mixed, showing both positive and negative results for their respective main outcome measures. For adenoid vegetation, asthma, and upper respiratory tract infection each, 2 trials are available that suggest no difference compared with placebo. For 4 conditions, only single trials are available. The authors concluded that the evidence from rigorous clinical trials of any type of therapeutic or preventive intervention testing homeopathy for childhood and adolescence ailments is not convincing enough for recommendations in any condition.
The Good Vibrations device is a radio-frequency instrument whose main objective is to teach children to pay better attention in class. It supposedly achieves this goal through the sending and receiving of gentle, pager-like vibrations from teacher to student. This device consists of 2 units: (i) a sending unit (teacher unit), and (ii) a receiving unit (student unit -- wristwatch). The teacher can send 2 types of vibrational signals -- one when the toggle switch is pressed down, triggering a long vibration (the reminder vibration) and the other when the button is pressed up, which triggers 4 short vibrations (the positive vibration. There is a lack of evidence regarding he effectiveness of this device in treating children with ADHD.
Karpouzis et al (2009) stated that the Neuro-Emotional Technique (NET), a branch of chiropractic, was designed to address the biopsychosocial aspects of acute and chronic conditions including non-musculoskeletal conditions. Anecdotally, it has been suggested that ADHD may be managed effectively by NET. A placebo-controlled, double-blind, randomized clinical trial was designed to assess the effectiveness of NET on a cohort of children with medically diagnosed ADHD. Children aged 5 to 12 years who met the inclusion criteria were randomixed to one of 3 groups -- the control group continued on their existing medical regimen and the intervention and placebo groups had the addition of the NET and sham NET protocols added to their regimen respectively. These 2 groups attended a clinical facility twice-weekly for the first month and then once-monthly for 6 months. The Conners' Parent and Teacher Rating Scales (CRS) were used at the start of the study to establish baseline data and then in 1 month and in 7 months time, at the conclusion of the study. The primary outcome measures chosen were the Conners' ADHD Index and Conners' Global Index. The secondary outcome measures chosen were the DSM-IV: Inattentive, the DSM-IV:Hyperactive-Impulsive, and the DSM-IV:Total subscales from the Conners' Rating Scales, monitoring changes in inattention, hyperactivity and impulsivity. Calculations for the sample size were set with a significance level of 0.05 and the power of 80 %, yielding a sample size of 93. The authors concluded that the present study should provide information as to whether the addition of NET to an existing medical regimen can improve outcomes for children with ADHD.
Neale and colleagues (2010) noted that although twin and family studies have shown ADHD to be highly heritable, genetic variants influencing the trait at a genome-wide significant level have yet to be identified. As prior genome-wide association studies (GWAS) have not yielded significant results, these researchers conducted a meta-analysis of existing studies to boost statistical power. They used data from 4 projects: (i) the Children's Hospital of Philadelphia (CHOP); (ii) phase I of the International Multicenter ADHD Genetics project (IMAGE); (iii) phase II of IMAGE (IMAGE II); and (iv) the Pfizer-funded study from the University of California, Los Angeles, Washington University, and Massachusetts General Hospital (PUWMa). The final sample size consisted of 2,064 trios, 896 cases, and 2,455 controls. For each study, these investigators imputed HapMap single nucleotide polymorphisms, computed association test statistics and transformed them to z-scores, and then combined weighted z-scores in a meta-analysis. No genome-wide significant associations were found, although an analysis of candidate genes suggests that they may be involved in the disorder. The authors concluded that given that ADHD is a highly heritable disorder, theser negative results suggested that the effects of common ADHD risk variants must, individually, be very small or that other types of variants, e.g., rare ones, account for much of the disorder's heritability.
The Quotient ADHD system/test takes 15 mins for children under the age of 13 years, or 20 mins for adolescents and adults. The system collects data on the person’s ability to sit still, inhibit impulsivity and respond accurately to images on a computer screen. The report provides analysis of motion, attention and shifts in attention states. Integrated composite scores report the level and severity of inattention, hyperactivity and impulsivity compared to other people of the same age and gender. The data are uploaded via a secure internet portal and the report is available within minutes. The clinician integrates the Quotient ADHD test report with information from other assessment tools and the clinical evaluation to help guide the discussion on treatment plan. There is a lack of scientific evidence regarding the validity of the Quotient ADHD test as a management tool for ADHD.
In a case-control study, Gilbert et al (2011) examined if transcranial magnetic stimulation (TMS)-evoked measures, particularly short interval cortical inhibition (SICI), in motor cortex correlate with the presence and severity of ADHD in childhood as well as with commonly observed delays in motor control. Behavioral ratings, motor skills, and motor cortex physiology were evaluated in 49 children with ADHD (mean age of 10.6 years, 30 boys) and 49 typically developing children (mean age of 10.5 years, 30 boys), all right-handed, aged 8 to 12 years. Motor skills were evaluated with the Physical and Neurological Examination for Subtle Signs (PANESS) and the Motor Assessment Battery for Children version 2; SICI and other physiologic measures were obtained using TMS in the left motor cortex. In children with ADHD, mean SICI was reduced by 40 % (p < 0.0001) and less SICI correlated with higher ADHD severity (r = -0.52; p = 0.002). Mean PANESS motor development scores were 59 % worse in children with ADHD (p < 0.0001). Worse PANESS scores correlated modestly with less SICI (r = -0.30; p = 0.01). The authors concluded that reduced TMS-evoked SICI correlates with ADHD diagnosis and symptom severity and also reflects motor skill development in children. They noted that "[t]his study was cross-sectional, and a longitudinal study might provide more readily interpretable insights into the relationship between age-related motor development, motor physiology, and ADHD...Such studies in ADHD in children might further enhance our understanding of SICI as a quantitative, biologically based marker of ADHD symptoms".
In a randomized controlled trial (the INCA Trial), Pelsser et al (2011) examined if there is a connection between diet and behavior in an unselected group of children. The "Impact of Nutrition on Children with ADHD (INCA)" study consisted of an open-label phase with masked measurements followed by a double-blind cross-over phase. Patients in the Netherlands and Belgium were enrolled via announcements in medical health centers and through media announcements. Randomization in both phases was individually done by random sampling. In the open-label phase (1st phase), children aged 4 to 8 years who were diagnosed with ADHD were randomly assigned to 5 weeks of a restricted elimination diet (diet group) or to instructions for a healthy diet (control group). Thereafter, the clinical responders (those with an improvement of at least 40 % on the ADHD rating scale [ARS]) from the diet group proceeded with a 4-week double-blind cross-over food challenge phase (2nd phase), in which high-IgG or low-IgG foods (classified on the basis of every child's individual IgG blood test results) were added to the diet. During the 1st phase, only the assessing pediatrician was masked to group allocation. During the 2nd phase (challenge phase), all persons involved were masked to challenge allocation. Primary end points were the change in ARS score between baseline and the end of the 1st phase (masked pediatrician) and between the end of the 1st phase and the 2nd phase (double-blind), and the abbreviated Conners' scale (ACS) score (unmasked) between the same time points. Secondary end points included food-specific IgG levels at baseline related to the behavior of the diet group responders after IgG-based food challenges. The primary analyses were intention-to-treat for the 1st phase and per protocol for the 2nd phase. Between November 4, 2008 and September 29, 2009, a total of 100 children were enrolled and randomly assigned to the control group (n = 50) or the diet group (n = 50). Between baseline and the end of the 1st phase, the difference between the diet group and the control group in the mean ARS total score was 23.7 (95 % confidence interval [CI]: 18.6 to 28.8; p < 0·0001) according to the masked ratings. The difference between groups in the mean ACS score between the same time points was 11.8 (95 % CI: 9.2 to 14.5; p < 0·0001). The ARS total score increased in clinical responders after the challenge by 20.8 (95 % CI: 14.3 to 27.3; p < 0.0001) and the ACS score increased by 11.6 (7.7 to 15.4; p < 0.0001). In the challenge phase, after challenges with either high-IgG or low-IgG foods, relapse of ADHD symptoms occurred in 19 of 30 (63 %) children, independent of the IgG blood levels. There were no harms or adverse events reported in both phases. The authors concluded that a strictly supervised restricted elimination diet is a valuable instrument to assess whether ADHD is induced by food. Moreover, the prescription of diets on the basis of IgG blood tests should be discouraged.
van Ewijk and colleagues (2012) stated that diffusion tensor imaging (DTI) allows in-vivo examination of the microstructural integrity of white matter brain tissue. These researchers performed a systematic review and quantitative meta-analysis using GingerALE to compare current DTI findings in patients with ADHD and healthy controls to further unravel the neurobiological underpinnings of the disorder. Online databases were searched for DTI studies comparing white matter integrity between ADHD patients and healthy controls. A total of 15 studies met inclusion criteria. Alterations in white matter integrity were found in widespread areas, most consistently so in the right anterior corona radiata, right forceps minor, bilateral internal capsule, and left cerebellum, areas previously implicated in the pathophysiology of the disorder. The authors concluded that while more research is needed, DTI proves to be a promising technique, providing new prospects and challenges for future research into the pathophysiology of ADHD.
