Attention deficit/hyperactivity disorder ( ADHD ) is one of the most common child psychiatric disorders , and is often treated with stimulant medication . Nonpharmacological treatments include dietary supplementation with omega-3 fatty acids , although their effectiveness remains to be shown conclusively . In this study , we investigated the effects of dietary omega-3 fatty acid supplementation on ADHD symptoms and cognitive control in young boys with and without ADHD . A total of 40 boys with ADHD , aged 8–14 years , and 39 matched , typically developing controls participated in a 16-week double-blind r and omized placebo-controlled trial . Participants consumed 10 g of margarine daily , enriched with either 650 mg of eicosapentaenoic acid (EPA)/docosahexaenoic acid ( DHA ) each or placebo . Baseline and follow-up assessment s addressed ADHD symptoms , fMRI of cognitive control , urine homovanillic acid , and cheek cell phospholipid sampling . EPA/DHA supplementation improved parent-rated attention in both children with ADHD and typically developing children . Phospholipid DHA level at follow-up was higher for children receiving EPA/DHA supplements than placebo . There was no effect of EPA/DHA supplementation on cognitive control or on fMRI measures of brain activity . This study shows that dietary supplementation with omega-3 fatty acids  reduces symptoms of ADHD , both for individuals with ADHD and typically developing children . This effect does not appear to be mediated by cognitive control systems in the brain , as no effect of supplementation was found here . Nonetheless , this study offers support that omega-3 supplementation may be an effective augmentation for pharmacological treatments of ADHD ( NCT01554462 : The Effects of EPA/DHA Supplementation on Cognitive Control in Children with ADHD ; http:// clinical trials.gov/show/NCT01554462 ) BACKGROUND Many studies suggest that electroencephalographic ( EEG ) neurofeedback might be beneficial in the treatment of attention-deficit hyperactivity disorder ( ADHD ) . However , numbers of well controlled studies are low and neurofeedback techniques are regarded as highly controversial . The present trial examined the efficacy ( compared with sham neurofeedback ) and efficiency ( compared with meta-cognitive therapy ) of a st and ard EEG neurofeedback protocol in adults with ADHD . METHODS We did a concurrent , triple-blind , r and omised , controlled trial using authorised deception in adults with ADHD from one centre ( University of Tübingen ) in Tübingen , Germany . Participants were eligible if they fulfilled the DSM-IV-TR criteria for ADHD , were aged between 18 years and 60 years , and had no or stable use of medication for at least 2 months with no intention to change . We excluded participants who had comorbid schizophrenia or schizoaffective disorder , bipolar disorder , borderline personality disorder , epilepsy , or traumatic brain injury ; substance abuse or dependence ; or current or planned other psychological treatment . Those eligible were r and omly assigned to three groups : a neurofeedback group which received 30 verum θ-to-β neurofeedback sessions over 15 weeks , a sham neurofeedback group which received 15 sham followed by 15 verum θ-to-β neurofeedback sessions over 15 weeks , or a meta-cognitive group therapy group which received 12 sessions over 12 weeks . Participants were assigned equally to one of the three interventions through a computerised minimisation r and omisation procedure stratified by sex , age , and baseline symptom severity of ADHD . Participants were masked as to whether they were receiving neurofeedback or sham neurofeedback , but those receiving meta-cognitive therapy were aware of their treatment . Clinical assessors ( ie , those assessing outcomes ) and research staff who did the neurofeedback training were masked to participants ' r and omisation status only for neurofeedback and sham neurofeedback . The primary outcome was symptom score on the Conners ' adult ADHD rating scale , assessed before treatment , at midtreatment ( after 8 weeks ) , after treatment ( after 16 weeks ) , and 6 months later . All individuals with at least one observation after r and omisation were included in the analyses . This trial is registered with Clinical Trials.gov , number NCT01883765 . FINDINGS Between Feb 1 , 2013 , and Dec 1 , 2015 , 761 people were assessed for eligibility . 656 ( 86 % ) were excluded and 118 ( 15 % ) were eligible for participation in this study . Eligible participants were r and omly assigned to neurofeedback ( 38 [ 32 % ] ) , sham neurofeedback ( 39 [ 33 % ] ) , or meta-cognitive therapy ( 41 [ 35 % ] ) . 37 ( 97 % ) individuals for neurofeedback , 38 ( 97 % ) for sham neurofeedback , and 38 ( 93 % ) for meta-cognitive therapy were included in analyses . Self-reported ADHD symptoms decreased substantially for all treatment groups ( B=-2·58 [ 95 % CI -3·48 to -1·68 ] ; p<0·0001 ) between pretreatment and the end of 6 month follow-up , independent of treatment condition ( neurofeedback vs sham neurofeedback B=-0·89 [ 95 % CI -2·14 to 0·37 ] , p=0·168 ; neurofeedback vs meta-cognitive therapy -0·30 [ -1·55 to 0·95 ] , p=0·639 ) . No treatment-related or trial-related serious adverse events were reported . INTERPRETATION Our findings suggest that neurofeedback training is not superior to a sham condition or group psychotherapy . All three treatments were equivalently effective in reducing ADHD symptoms . This first r and omised , sham-controlled trial did not show any specific effects  of neurofeedback  on ADHD symptoms in adults . FUNDING German Research Foundation In recent years a rising amount of r and omized controlled trials , review s , and meta-analyses relating to the efficacy of electroencephalographic-neurofeedback ( EEG-NF ) in children with attention-deficit/hyperactivity disorder ( ADHD ) have been published . Although clinical reports and open treatment studies suggest EEG-NF to be effective , double blind placebo-controlled studies as well as a rigorous meta- analysis failed to find support for the efficacy of EEG-NF . Since absence of evidence does not equate with evidence of absence , we will outline how future research might overcome the present method ological limitations . To provide conclusive evidence for the presence or absence of the efficacy of EEG-NF  in the treatment of ADHD , there is a need to set up a well- design ed study that ensures optimal implementation and embedding of the training , and possibly incorporates different forms of neurofeedback OBJECTIVE To determine whether supplementation with the long-chain omega-3 polyunsaturated fatty acids eicosapentaenoic ( EPA ) and docosahexaenoic acid ( DHA ) affects behavioral symptoms and cognitive impairments in children 6 - 12 years of age diagnosed with attention-deficit/hyperactivity disorder ( ADHD ) . STUDY DESIGN The r and omized , double-blind placebo-controlled 16 weeks trial was conducted with 95 children diagnosed with ADHD according to DSM-IV criteria . Behavior was assessed by parents , teachers and investigators using st and ardized rating scales and question naires . Further outcome variables were working memory , speed of information processing and various measures of attention . For a subgroup of 81 participants , erythrocyte membrane fatty acid composition was analyzed before and after the intervention . RESULTS Supplementation with the omega-3 fatty acid mix increased EPA and DHA concentrations in erythrocyte membranes and improved working memory function , but had no effect on other cognitive measures and parent- and teacher-rated behavior in the study population . Improved working memory correlated significantly with increased EPA , DHA and decreased AA ( arachidonic acid ) BACKGROUND The role of nutrition in the treatment of  attention-deficit hyperactivity disorder ( ADHD )  is gaining international attention ; however , treatments have generally focused only on diet restriction or supplementing with one nutrient at a time . AIMS To investigate the efficacy and safety of a broad-based micronutrient formula consisting mainly of vitamins and minerals , without omega fatty acids , in the treatment of ADHD in adults . METHOD This double-blind r and omised controlled trial assigned 80 adults with ADHD in a 1:1 ratio to either micronutrients  ( n = 42 ) or  placebo ( n = 38 ) for 8 weeks ( trial registered with the Australian New Zeal and Clinical Trials Registry : ACTRN12609000308291 ) . RESULTS Intent-to-treat analyses showed significant between-group differences favouring active treatment on self- and observer- but not clinician-ADHD rating scales . However , clinicians rated those receiving micronutrients as more improved than those on placebo both globally and on ADHD symptoms . Post hoc analyses showed that for those with moderate/severe depression  at baseline , there was a greater change in mood favouring active treatment over placebo . There were no group differences in adverse events . CONCLUSIONS This study provides preliminary evidence of efficacy for micronutrients in the treatment of  ADHD symptoms in adults , with a reassuring safety profile Clinical trials have suggested that neurofeedback may be efficient in treating attention-deficit/hyperactivity disorder ( ADHD ) . We compared the effects of a 3-month electroencephalographic feedback program providing reinforcement contingent on the production of cortical sensorimotor rhythm ( 12–15 Hz ) and beta1 activity ( 15–18 Hz ) with stimulant medication . Participants were N = 34 children aged 8–12 years , 22 of which were assigned to the neurofeedback group and 12 to the methylpheni date group according to their parents ' preference . Both neurofeedback and methylpheni date were associated with improvements on all subscales of the Test of Variables of Attention , and on the speed and accuracy measures of the d2 Attention Endurance Test . Furthermore , behaviors related to the disorder were rated as significantly reduced in both groups by both teachers and parents on the IOWA-Conners Behavior Rating Scale . These findings suggest that neurofeedback was efficient in improving some of the behavioral concomitants of ADHD in children whose parents favored a nonpharmacological treatment Objective : To evaluate the efficacy of 2 computer attention training systems administered in school for children with attention-deficit hyperactivity disorder ( ADHD ) . Method : Children in second and fourth grade with a diagnosis of ADHD ( n = 104 ) were r and omly assigned to neurofeedback ( NF ) ( n = 34 ) , cognitive training ( CT ) ( n = 34 ) , or control ( n = 36 ) conditions . A 2-point growth model assessed change from pre-post intervention on parent reports ( Conners 3-Parent [ Conners 3-P ] ; Behavior Rating Inventory of Executive Function [ BRIEF ] rating scale ) , teacher reports ( Swanson , Kotkin , Agler , M-Flynn and Pelham scale [ SKAMP ] ; Conners 3-Teacher [ Conners 3-T ] ) , and systematic classroom observations ( Behavioral Observation of Students in Schools [ BOSS ] ) . Paired t tests and an analysis of covariance assessed change in medication . Results : Children who received NF showed significant improvement compared with those in the control condition on the Conners 3-P Attention , Executive Functioning and Global Index , on all BRIEF summary indices , and on BOSS motor/verbal off-task behavior . Children who received CT showed no improvement compared to the control condition . Children in the NF condition showed significant improvements compared to those in the CT condition on Conners 3-P Executive Functioning , all BRIEF summary indices , SKAMP Attention , and Conners 3-T Inattention subscales . Stimulant medication dosage in methylpheni date equivalencies significantly increased for children in the CT ( 8.54 mg ) and control ( 7.05 mg ) conditions but not for those in the NF condition ( 0.29 mg ) . Conclusion : Neurofeedback made greater improvements in ADHD symptoms compared to both the control and CT conditions . Thus , NF is a promising attention training treatment intervention for children with ADHD OBJECTIVE To determine whether docosahexaenoic acid ( DHA ) supplementation for 4 months decreases the symptoms of  attention-deficit/hyperactivity disorder ( ADHD ) .  STUDY DESIGN Sixty-three 6- to-12-year-old children with ADHD , all receiving effective maintenance therapy with stimulant medication , were assigned r and omly , in a double-blind fashion , to receive DHA supplementation ( 345 mg/d ) or placebo for 4 months . Outcome variables included plasma phospholipid fatty acid patterns , scores on laboratory measures of inattention and impulsivity ( Test of Variables of Attention , Children 's Color Trails test ) while not taking stimulant medication , and scores on parental behavioral rating scales ( Child Behavior Checklist , Conners ' Rating Scale ) . Differences between groups after 4 months of DHA supplementation or placebo administration were determined by analysis of variance , controlling for age , baseline value of each outcome variable , ethnicity , and ADHD subtype . RESULTS Plasma phospholipid DHA content of the DHA-supplemented group was 2.6-fold higher at the end of the study than that of the placebo group ( 4.85 + /- 1.35 vs 1.86 + /- 0.87 mol % of total fatty acids ; P < .001 ) . Despite this , there was no statistically significant improvement in any objective or subjective measure of ADHD symptoms . CONCLUSION A 4-month period of DHA supplementation ( 345 mg/d ) does not decrease symptoms of ADHD OBJECTIVE The efficacy of neurofeedback as a treatment for attention-deficit/hyperactivity disorder ( ADHD ) , and whether neurofeedback is a viable alternative for stimulant medication , is still an intensely debated subject . The current r and omized controlled trial compared neurofeedback to ( 1 ) optimally titrated methylpheni date and ( 2 ) a semi-active control intervention , physical activity , to account for nonspecific effects . METHODS A multicenter 3-way parallel-group study with balanced r and omization was conducted . Children with a DSM-IV-TR diagnosis of ADHD , aged 7 - 13 years , were r and omly allocated to receive neurofeedback ( n = 39 ) , methylpheni date ( n = 36 ) , or physical activity ( n = 37 ) over a period of 10 - 12 weeks . Neurofeedback comprised theta/beta training on the vertex ( Cz ) . Physical activity consisted of moderate to vigorous intensity exercises . Neurofeedback and physical activity were balanced in terms of number ( ~30 ) and duration of sessions . A double-blind pseudor and omized placebo-controlled crossover titration procedure was used to determine an optimal dose in the methylpheni date intervention . Parent and teacher ratings on the Strengths and Difficulties Question naire ( SDQ ) and Strengths and Weaknesses of ADHD Symptoms and Normal Behavior ( SWAN ) were used to assess intervention outcomes . Data collection took place between September 2010 and March 2014 . RESULTS Intention-to-treat analyses revealed an improvement in parent-reported behavior on the SDQ and the SWAN Hyperactivity/Impulsivity scale , irrespective of received intervention ( ηp² = 0.21 - 0.22 , P ≤ .001 ) , whereas the SWAN Inattention scale revealed more improvement in children who received methylpheni date than neurofeedback and physical activity ( ηp² = 0.13 , P ≤ .001 ) . Teachers reported a decrease of ADHD symptoms on all measures for methylpheni date , but not for neurofeedback or physical activity ( range of ηp² = 0.14 - 0.29 , P < .001 ) . CONCLUSIONS The current study found that optimally titrated methylpheni date is superior to neurofeedback and physical activity in decreasing ADHD symptoms in children with ADHD . TRIAL REGISTRATION Clinical Trials.gov identifier : NCT01363544 OBJECTIVE Electroencephalographic ( EEG ) neurofeedback ( NF ) is considered a nonpharmacological alternative for medication in attention-deficit/hyperactivity disorder ( ADHD ) . Comparisons of the behavioral efficacy of NF and medication have produced inconsistent results . EEG measures can provide insight into treatment mechanisms , but have received little consideration . In this r and omized controlled trial ( RCT ) , effects of NF were compared with methylpheni date ( MPH ) , and physical activity ( PA ) in children with ADHD on event-related potential ( ERP ) indices of response inhibition , which are involved in ADHD psychopathology . METHODS Using a multicenter three way parallel group RCT design , 112 children with a Diagnostic and Statistical Manual of Mental Disorders , 4th ed . ( DSM-IV ) ( American Psychiatric Association 1994 ) diagnosis of ADHD , between 7 and 13 years of age , were initially included .  NF training consisted of 30 sessions of theta/beta training at Cz over a 10 week period . PA training was a semiactive control group , matched in frequency and duration . MPH was titrated using a double-blind placebo controlled procedure in 6 weeks , followed by a stable dose for 4 weeks . ERP measures of response inhibition , N2 and P3 , were available for 81 children at pre- and postintervention ( n = 32 NF , n = 25 MPH , n = 24 PA ) . RESULTS Only the medication group showed a specific increase in P3 amplitude compared with NF ( partial eta-squared [ ηp(2 ) ] = 0.121 ) and PA ( ηp(2 ) = 0.283 ) , which was related to improved response inhibition . Source localization of medication effects on P3 amplitude indicated increased activation primarily in thalamic and striatal nuclei . CONCLUSIONS This is the first study that simultaneously compared NF with stimulant treatment and a semiactive control group . Only stimulant treatment demonstrated specific improvements in brain function related to response inhibition . These results are in line with recent doubts on the efficacy and specificity of NF as treatment for ADHD . CLINICAL TRIALS REGISTRATION Train Your Brain ?

No. NCT01363544 OBJECTIVE To determine the effects of an eicosapentaenoic acid (EPA)-rich oil and a docosahexaenoic acid (DHA)-rich oil versus an ω-6 polyunsaturated fatty acid-rich safflower oil ( control ) on literacy and behavior in children with attention-deficit/hyperactivity disorder ( ADHD ) in a r and omized controlled trial . METHODS Supplements rich in EPA , DHA , or safflower oil were r and omly allocated for 4 mo to 90 Australian children 7 to 12 y old with ADHD symptoms higher than the 90th percentile on the Conners Rating Scales . The effect of supplementation on cognition , literacy , and parent-rated behavior was assessed by linear mixed modeling . Pearson correlations determined associations between the changes in outcome measurements and the erythrocyte fatty acid content ( percentage of total ) from baseline to 4 mo . RESULTS There were no significant differences between the supplement groups in the primary outcomes after 4 mo . However , the erythrocyte fatty acid profiles indicated that an increased proportion of DHA was associated with improved word reading ( r = 0.394 ) and lower parent ratings of oppositional behavior ( r = 0.392 ) . These effects were more evident in a subgroup of 17 children with learning difficulties : an increased erythrocyte DHA was associated with improved word reading ( r = 0.683 ) , improved spelling ( r = 0.556 ) , an improved ability to divide attention ( r = 0.676 ) , and lower parent ratings of oppositional behavior ( r = 0.777 ) , hyperactivity ( r = 0.702 ) , restlessness ( r = 0.705 ) , and overall ADHD symptoms ( r = 0.665 ) . CONCLUSION Increases in erythrocyte ω-3 polyunsaturated fatty acids , specifically DHA , may improve literacy and behavior in children with ADHD . The greatest benefit may be observed in children who have comorbid learning difficulties The present study is a r and omized controlled trial that aims to evaluate the efficacy of Neurofeedback compared to st and ard pharmacological intervention in the treatment of attention deficit/hyperactivity disorder ( ADHD ) . The final sample consisted of 23 children with ADHD ( 11 boys and 12 girls , 7 - 14 years old ) . Participants carried out 40 theta/beta training sessions or received methylpheni date .  Behavioral rating scales were completed by fathers , mothers , and teachers at pre- , post-treatment , two- , and six-month naturalistic follow-up . In both groups , similar significant reductions were reported in ADHD functional impairment by parents ; and in primary ADHD symptoms by parents and teachers . However , significant academic performance improvements were only detected in the Neurofeedback group .

To our knowledge , this is the first r and omized controlled trial with a six-month follow-up that compares Neurofeedback and stimulant medication in ADHD Attention Deficit Hyperactivity Disorder ( ADHD ) is characterized by poor cognitive control/attention and hypofunctioning of the dorsal anterior cingulate cortex ( dACC ) . In the current study , we investigated for the first time whether real-time fMRI neurofeedback ( rt-fMRI ) training targeted at increasing activation levels within dACC in adults with ADHD leads to a reduction of clinical symptoms and improved cognitive functioning . An exploratory r and omized controlled treatment study with blinding of the participants was conducted . Participants with ADHD ( n = 7 in the neurofeedback group , and n = 6 in the control group ) attended four weekly MRI training sessions ( 60-min training time/session ) , during which they performed a mental calculation task at varying levels of difficulty , in order to learn how to up-regulate dACC activation . Only neurofeedback participants received continuous feedback information on actual brain activation levels within dACC . Before and after the training , ADHD symptoms and relevant cognitive functioning was assessed . Results showed that both groups achieved a significant increase in dACC activation levels over sessions . While there was no significant difference between the neurofeedback and control group in clinical outcome , neurofeedback participants showed stronger improvement on cognitive functioning . The current study demonstrates the general feasibility of the suggested rt-fMRI neurofeedback training approach as a potential novel treatment option for ADHD patients . Due to the study ’s small sample size , potential clinical benefits need to be further investigated in future studies . Trial Registration : IS RCT BACKGROUND An abnormality in long chain-polyunsaturated fatty acid ( LC-PUFA ) levels has been implicated in attention-deficit/hyperactivity disorder ( ADHD ) . Studies evaluating LC-PUFA supplementation for therapeutic efficacy in ADHD have shown mixed and , therefore , inconclusive results . METHODS Seventy-six male adolescents ( age 12 - 16 years , mean = 13.7 ) with ADHD were assessed for the effects of 12 weeks omega-3 and omega-6 supplements on biochemical and psychological outcomes in a r and omized , placebo-controlled , clinical trial . The primary outcome measure was change in the Conners ' Teacher Rating Scales ( CTRS ) following 12 weeks of supplementation of LC-PUFA or placebo . At baseline , the placebo and treatment groups had comparable levels of LC-PUFA as measured by red blood cell phosphatidylcholine . In the treatment group , supplementation enhanced eicosapentaenoic acid ( EPA ) , docosahexaenoic acid ( DHA ) , and total omega-3 fatty acid levels . RESULTS No superiority of LC-PUFAs to placebo was observed on the primary outcome . Further , there were no reliable treatment effects on aggression , impulsivity , depression , and anxiety . CONCLUSIONS Future studies should use larger sample sizes and longer supplementation period to detect small-modest effects for clinical recommendations in ADHD Objective Clinical trials and inconclusive meta-analyses have investigated the effects of omega-3 supplements in children with Attention-Deficit Hyperactivity Disorder ( ADHD ) . We performed a r and omised placebo-controlled trial to evaluate the efficacy of omega-3 fatty acids . Methods Children aged 6–15 years with established diagnosis of ADHD were r and omised 1:1 to receive either supplements containing docosahexaenoic acid ( DHA ) and eicosapentaenoic acid ( EPA ) or a placebo for 3 months . Psychotropic or omega-3-containing treatments were not authorised during the study . The primary outcome was the change in the Attention-Deficit Hyperactivity Disorder Rating Scale version 4 ( ADHD-RS-IV ) . Other outcomes included safety , lexical level ( Alouette test ) , attention ( Test of Attentional Performance for Children — KiTAP ) , anxiety ( 48-item Conners Parent Rating Scale-Revised — CPRS-R ) , and depression ( Children ’s Depression Inventory — CDI ) . Results Between 2009 and 2011 , 162 children were included in five French child psychiatry centres . The mean age was 9.90 ( SD 2.62 ) years and 78.4 % were boys . The inclusion ADHD-RS-IV at was 37.31 ( SD 8.40 ) . The total ADHD-RS-IV score reduction was greater in the placebo group than in the DHA – EPA group : −19 ( −26 , −12 ) % and −9.7 ( −16.6 , −2.9 ) % , respectively , p = 0.039 . The other components of the Conners score had a similar variation but the differences between groups were not significant . Two patients in the DHA – EPA group and none in the placebo group experienced a severe adverse event ( hospitalisation for worsening ADHD symptoms ) . Conclusion This study did not show any beneficial effect of omega-3 supplement in children with mild ADHD symptoms The aim of this study is to assess the efficacy of a restricted elimination diet in reducing symptoms in an unselected group of children with Attention deficit/hyperactivity disorder ( ADHD ) . Dietary studies have already shown evidence of efficacy in selected subgroups . Twenty-seven children ( mean age 6.2 ) who all met the DSM-IV criteria for ADHD , were assigned r and omly to either an intervention group ( 15/27 ) or a waiting-list control group ( 12/27 ) . Primary endpoint was the clinical response , i.e. a decrease in the symptom scores by 50 % or more , at week 9 based on parent and teacher ratings on the abbreviated ten-item Conners Scale and the ADHD-DSM-IV Rating Scale . The intention-to-treat analysis showed that the number of clinical responders in the intervention group was significantly larger than that in the control group [ parent ratings 11/15 ( 73 % ) versus 0/12 ( 0 % ) ; teacher ratings , 7/10 ( 70 % ) versus 0/7 ( 0 % ) ] . The Number of ADHD criteria on the ADHD Rating Scale showed an effect size of 2.1 ( cohen ’s d ) and a scale reduction of 69.4 % . Comorbid symptoms of oppositional defiant disorder also showed a significantly greater decrease in the intervention group than it did in the control group ( cohens ’s d 1.1 , scale reduction 45.3 % ) . A strictly supervised elimination diet may be a valuable instrument in testing young children with ADHD on whether dietary factors may contribute to the manifestation of the disorder and may have a beneficial effect on the children ’s behaviour Objective . This study examined the efficacy of 2 computer-based training systems to teach children with attention deficit/hyperactivity disorder ( ADHD ) to attend more effectively . Design / methods . A total of 41 children with ADHD from 2 middle schools were r and omly assigned to receive 2 sessions a week at school of either neurofeedback ( NF ) or attention training through a st and ard computer format ( SCF ) , either immediately or after a 6-month wait ( waitlist control group ) . Parents , children , and teachers completed question naires pre- and postintervention . Results . Primary parents in the NF condition reported significant ( P < .05 ) change on Conners ’s Rating Scales — Revised ( CRS-R ) and Behavior Assessment Scales for Children ( BASC ) subscales ; and in the SCF condition , they reported significant ( P < .05 ) change on the CRS-R Inattention scale and ADHD index , the BASC Attention Problems Scale , and on the Behavioral Rating Inventory of Executive Functioning ( BRIEF ) . Conclusion . This r and omized control trial provides preliminary evidence of the effectiveness of computer-based interventions for ADHD and supports the feasibility of offering them in a school setting OBJECTIVE : To evaluate sustained improvements 6 months after a 40-session , in-school computer attention training intervention using neurofeedback or cognitive training ( CT ) administered to 7- to 11-year-olds with attention-deficit/hyperactivity disorder ( ADHD ) . METHODS : One hundred four children were r and omly assigned to receive neurofeedback , CT , or a control condition and were evaluated 6 months postintervention . A 3-point growth model assessed change over time across the conditions on the Conners 3–Parent Assessment Report ( Conners 3-P ) , the Behavior Rating Inventory of Executive Function Parent Form ( BRIEF ) , and a systematic double-blinded classroom observation ( Behavioral Observation of Students in Schools ) . Analysis of variance assessed community-initiated changes in stimulant medication . RESULTS : Parent response rates were 90 % at the 6-month follow-up . Six months postintervention , neurofeedback participants maintained significant gains on Conners 3-P ( Inattention effect size [ ES ] = 0.34 , Executive Functioning ES = 0.25 , Hyperactivity/Impulsivity ES = 0.23 ) and BRIEF subscales including the Global Executive Composite ( ES = 0.31 ) , which remained significantly greater than gains found among children in CT and control conditions . Children in the CT condition showed delayed improvement over immediate postintervention ratings only on Conners 3-P Executive Functioning ( ES = 0.18 ) and 2 BRIEF subscales . At the 6-month follow-up , neurofeedback participants maintained the same stimulant medication dosage , whereas participants in both CT and control conditions showed statistically and clinical ly significant increases ( 9 mg [ P = .002 ] and 13 mg [ P < .001 ] , respectively ) . CONCLUSIONS : Neurofeedback participants made more prompt and greater improvements in ADHD symptoms , which were sustained at the 6-month follow-up , than did CT participants or those in the control group . This finding suggests that neurofeedback is a promising attention training treatment for children with ADHD OBJECTIVE Neurofeedback aims to reduce symptoms of attention-deficit/hyperactivity disorder ( ADHD ) , mainly attention problems . However , the additional influence of neurofeedback over treatment as usual ( TAU ) on neurocognitive functioning for adolescents with ADHD remains unclear . METHOD By using a multicenter parallel r and omized controlled trial ( RCT ) design , male adolescents with a DSM-IV-TR diagnosis of ADHD ( mean age = 16.1 years ; range , 12 - 24 ) were r and omized to receive either a combination of TAU and neurofeedback ( n = 45 ) or TAU ( n = 26 ) . R and omization was computer generated and stratified by age group ( ages 12 through 15 , 16 through 20 , and 21 through 24 years ) . The neurofeedback intervention consisted of approximately 37 sessions over a period of 25 weeks of theta/sensorimotor rhythm training on the vertex ( Cz ) . Primary neurocognitive outcomes included performance parameters derived from the D2 Test of Attention , the Digit Span backward , the Stroop Color-Word Test and the Tower of London , all assessed preintervention and postintervention . Data were collected between December 2009 and July 2012 . RESULTS At postintervention , outcomes of attention and /or motor speed were improved , with faster processing times for both intervention conditions and with medium to large effect sizes ( range , ηp2 = .08-.54 ; P values < .023 ) . In both groups , no improvements for higher executive functions were observed . Results might partly resemble practice effects . CONCLUSIONS Although neurocognitive outcomes improved in all adolescents receiving treatment for ADHD , no additional value for neurofeedback over TAU was observed . Hence , this study does not provide evidence for using theta/sensorimotor rhythm neurofeedback to enhance neurocognitive performance as additional intervention to TAU for adolescents with ADHD symptoms . TRIAL REGISTRATION Trialregister.nl identifier : 1759 Objective : To investigate effects of omega-3 polyunsaturated fatty acids ( n-3 PUFA ) docosahexaenoic acid ( DHA ) and eicosapentaenoic acid ( EPA ) on attention , literacy , and behavior in children with ADHD . Method : Ninety children were r and omized to consume supplements high in EPA , DHA , or linoleic acid ( control ) for 4 months each in a crossover design . Erythrocyte fatty acids , attention , cognition , literacy , and Conners ’ Parent Rating Scales ( CPRS ) were measured at 0 , 4 , 8 , 12 months . Results : Fifty-three children completed the treatment . Outcome measures showed no significant differences between the three treatments . However , in children with blood sample s ( n = 76 - 46 ) , increased erythrocyte EPA + DHA was associated with improved spelling ( r = .365 , p < .001 ) and attention ( r = −.540 , p < .001 ) and reduced oppositional behavior ( r = −.301 , p < .003 ) , hyperactivity ( r = −.310 , p < .001 ) , cognitive problems ( r = −.326 , p < .001 ) , Diagnostic and Statistical Manual of Mental Disorders ( 4th ed . ; DSM-IV ) hyperactivity ( r = −.270 , p = .002 ) and DSM-IV inattention ( r = −.343 , p < .001 ) . Conclusion : Increasing erythrocyte DHA and EPA via dietary supplementation may improve behavior , attention , and literacy in children with ADHD Neurofeedback has been proposed as a potentially effective intervention for reducing Attention Deficit Hyperactivity Disorder ( ADHD ) symptoms . However , it remains unclear whether neurofeedback is of additional value to treatment as usual ( TAU ) for adolescents with clinical ADHD symptoms . Using a multicenter parallel-r and omized controlled trial design , adolescents with ADHD symptoms were r and omized to receive either a combination of TAU and neurofeedback ( NFB + TAU , n = 45 ) or TAU-only ( n = 26 ) . R and omization was computer generated and stratified for age group ( ages 12 through 16 , 16 through 20 , 20 through 24 ) .  Neurofeedback treatment consisted of approximately 37 sessions of theta/sensorimotor rhythm (SMR)-training on the vertex ( Cz ) . Primary behavioral outcome measures included the ADHD-rating scale , Youth Self Report , and Child Behavior Checklist all assessed pre- and post-intervention . Behavioral problems decreased equally for both groups with medium to large effect sizes , range of partial η2 = 0.08–0.31 , p < 0.05 . Hence , the combination of NFB + TAU was not more effective than TAU-only on the behavioral outcome measures . In addition , reported adverse effects were similar for both groups . On behavioral outcome measures , the combination of neurofeedback and TAU was as effective as TAU-only for adolescents with ADHD symptoms . Considering the absence of additional behavioral effects in the current study , in combination with the limited knowledge of specific treatment effects , it is question able whether theta/SMR neurofeedback for adolescents with ADHD and comorbid disorders in clinical practice should be used . Further research is warranted to investigate possible working mechanisms and ( long-term ) specific treatment effects of neurofeedback BACKGROUND Attention-deficit/hyperactivity disorder ( ADHD ) is associated with difficulties in learning , behaviour and psychosocial adjustment that persist into adulthood . Decreased omega-3 fatty acids and increased inflammation or oxidative stress may contribute to neuro-developmental and psychiatric disorders such as ADHD . The aim of this study was to determine the effect of n-3 supplementation on hyperactivity , oxidative stress and inflammatory mediators in children with ADHD . METHODS In this double blind study , 103 children ( 6 - 12 years ) with ADHD receiving maintenance therapy were assigned r and omly into two groups . The n-3 group received n-3 fatty acids ( 635 mg eicosapentaenoic acid ( EPA ) , 195 mg docosahexaenoic acid ( DHA ) ) , and the placebo group received olive oil capsules which were visually similar to the n-3 capsules . The duration of supplementation was 8 weeks . Plasma C-reactive protein ( CRP ) , interleukin-6 ( IL-6 ) and the activity of glutathione reductase ( GR ) , catalase ( CAT ) and superoxide dismutase ( SOD ) were determined before and after the intervention . Likewise the Conners ' Abbreviated Question naires ( ASQ-P ) was applied . RESULTS After 8-week intervention , a significant reduction was observed in the levels of CRP ( P < 0.05 , 95 % CI = 0.72 - 2.02 ) and IL-6 ( P < 0.001 , 95 % CI = 1.93 - 24.33 ) in the n-3 group . There was also a significant increase in activity of SOD and GR ( P < 0.001 ) . A significant improvement was seen in the ASQ-P scores in the n-3 group ( P < 005 ) . CONCLUSION Eight weeks of EPA and DHA supplementation decreased plasma inflammatory mediators and oxidative stress in the children with ADHD . These results suggest that n-3 fatty acid supplementation may offer a safe and efficacious treatment for children with ADHD
Free fatty acid supplementation produced small but significant reductions in ADHD symptoms even with probably blinded assessment s , although the clinical significance of these effects remains to be determined .
Artificial food color exclusion produced larger effects but often in individuals selected for food sensitivities .
OBJECTIVE Nonpharmacological treatments are available for attention deficit hyperactivity disorder ( ADHD ) , although their efficacy remains uncertain .
The authors undertook meta-analyses of the efficacy of dietary ( restricted elimination diets , artificial food color exclusions , and free fatty acid supplementation ) and psychological ( cognitive training , neurofeedback , and behavioral interventions ) ADHD treatments .
