The Preschool Attention-Deficit/Hyperactivity Disorder Treatment Study (PATS) 6-year follow-up.

ABSTRACT: To describe the clinical course of attention-deficit/hyperactivity disorder (ADHD) symptom severity and diagnosis from ages 3 to 5 up to 9 to 12 years during a 6-year follow-up after the original Preschool ADHD Treatment Study (PATS).A total of 207 participants (75% male) from the original PATS, assessed at baseline (mean age, 4.4 years, when all met criteria for ADHD) and 3 months later (before medication treatment), were re-evaluated in three follow-up assessment visits (year 3, mean age 7.4 years; year 4, 8.3 years; and year 6, 10.4 years). Parents and teachers rated symptom severity, and clinicians established psychiatric diagnoses. Analyses examined longitudinal changes in symptom severity and ADHD diagnosis.Parent- and teacher-rated symptom severity decreased from baseline to year 3 but remained relatively stable and in the moderate-to-severe clinical range through year 6. Girls showed generally steeper decreases in symptom T-scores. At year 6, 89% (160/180) of remaining participants met ADHD symptom and impairment diagnostic criteria. Comorbidity of oppositional defiant disorder and/or conduct disorder was associated with a 30% higher risk of having an ADHD diagnosis at year 6 in the multiple logistic model. Medication status during follow-up, on versus off, did not predict symptom severity change from year 3 to year 6 after adjustment for other variables.ADHD in preschoolers is a relatively stable diagnosis over a 6-year period. The course is generally chronic, with high symptom severity and impairment, in very young children with moderate-to-severe ADHD, despite treatment with medication. Development of more effective ADHD intervention strategies is needed for this age group.

Project description:Volumetric studies have reported relatively decreased cortical thickness and gray matter volumes in adults with attention-deficit/hyperactivity disorder (ADHD) whose childhood status was retrospectively recalled. We present, to our knowledge, the first prospective study combining cortical thickness and voxel-based morphometry in adults diagnosed as having ADHD in childhood.To test whether adults with combined-type childhood ADHD exhibit cortical thinning and decreased gray matter in regions hypothesized to be related to ADHD and to test whether anatomic differences are associated with a current ADHD diagnosis, including persistent vs remitting ADHD.Cross-sectional analysis embedded in a 33-year prospective follow-up at a mean age of 41.2 years.Research outpatient center.We recruited probands with ADHD from a cohort of 207 white boys aged 6 to 12 years. Male comparison participants (n = 178) were free of ADHD in childhood. We obtained magnetic resonance images in 59 probands and 80 comparison participants (28.5% and 44.9% of the original samples, respectively).Whole-brain voxel-based morphometry and vertexwise cortical thickness analyses.The cortex was significantly thinner in ADHD probands than in comparison participants in the dorsal attentional network and limbic areas (false discovery rate < 0.05, corrected). In addition, gray matter was significantly decreased in probands in the right caudate, right thalamus, and bilateral cerebellar hemispheres. Probands with persistent ADHD (n = 17) did not differ significantly from those with remitting ADHD (n = 26) (false discovery rate < 0.05). At uncorrected P < .05, individuals with remitting ADHD had thicker cortex relative to those with persistent ADHD in the medial occipital cortex, insula, parahippocampus, and prefrontal regions.Anatomic gray matter reductions are observable in adults with childhood ADHD, regardless of the current diagnosis. The most affected regions underpin top-down control of attention and regulation of emotion and motivation. Exploratory analyses suggest that diagnostic remission may result from compensatory maturation of prefrontal, cerebellar, and thalamic circuitry.

Project description:ObjectiveTo examine delayed effects of theta-beta ratio (TBR) neurofeedback (NF) for attention-deficit/hyperactivity disorder (ADHD) 25 months after baseline, ∼21 months after end of treatment.MethodChildren aged 7 to 10 years with rigorously diagnosed ADHD had been randomized to 38 sessions of TBR NF (n = 84) or control treatment (n = 58) of identical appearance, intensity/frequency, and duration, differing only in that reinforcement for controls was based on a pre-recorded electroencephalogram (EEG) of another child. Child, parent, and all site staff were blinded until after 25-month assessments, with only one-fourth able to guess the control treatment correctly. Baseline assessments were repeated off medication after 25 months.ResultsOf the 142 participants, 120 had 25-month follow-up (84.5% retention). Only 12 participants (6 controls) had NF after the study treatment, greatly retaining the randomization. The primary outcome, parent-rated inattention, was not significantly different between treatments despite large pre-post effect sizes (NF recipients, d = 1.63; controls, d = 1.42). Most secondary measures showed the same pattern. Response rates (Clinical Global Impression-Improvement ≤2) were 58.6% of NF recipients and 66% of controls (not significant). Marginally more controls than NF recipients needed medication (57.1% vs 38.6%, p = .059); specifically, 7.1% of NF recipients and 4% of controls had reduced medication need, whereas 34.3% of NF recipients and 50% of controls needed more medication (p = 0.084).ConclusionMost of the large within-group improvement from the NF treatment package reported by unblinded studies and replicated in this blinded study reflects nonspecific effects, not specific effects of deliberate down-training of EEG theta-beta power ratio. At 25-month follow-up, it appears comparable to the evidence-based Multimodal Treatment Study of ADHD (MTA) treatments, suggesting a psychotherapeutic/behavioral effect.Clinical trial registration informationDouble-Blind 2-Site Randomized Clinical Trial of Neurofeedback for ADHD; http://clinicaltrials.gov/; NCT02251743.Diversity & inclusion statementWe worked to ensure sex and gender balance in the recruitment of human participants.

Project description:Importance:Knowledge about the long-term effects of multimodal treatment in adult attention-deficit/hyperactivity disorder (ADHD) is much needed. Objective:To evaluate the long-term efficacy of multimodal treatment for adult ADHD. Design, Setting, and Participants:This observer-masked, 1.5-year follow-up of the Comparison of Methylphenidate and Psychotherapy in Adult ADHD Study (COMPAS), a prospective, multicenter randomized clinical trial, compared cognitive behavioral group psychotherapy (GPT) with individual clinical management (CM) and methylphenidate (MPH) with placebo (2?×?2 factorial design). Recruitment started January 2007 and ended August 2010, and treatments were finalized in August 2011 with follow-up through March 2013. Overall, 433 adults with ADHD participated in the trial, and 256 (59.1%) participated in the follow-up assessment. Analysis began in November 2013 and was completed in February 2018. Interventions:After 1-year treatment with GPT or CM and MPH or placebo, no further treatment restrictions were imposed. Main Outcomes and Measures:The primary outcome was change in the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score from baseline to follow-up. Secondary outcomes included further ADHD rating scale scores, observer-masked ratings of the Clinical Global Impression scale, and self-ratings of depression on the Beck Depression Inventory. Results:At follow-up, 256 of 433 randomized patients (baseline measured in 419 individuals) participated. Of the 256 patients participating in follow-up, the observer-masked ADHD Index of Conners Adult ADHD Rating Scale score was assessed for 251; the mean (SD) baseline age was 36.3 (10.1) years; 125 patients (49.8%) were men; and the sample was well-balanced with respect to prior randomization (GPT and MPH: 64 of 107; GPT and placebo: 67 of 109; CM and MPH: 70 of 110; and CM and placebo: 55 of 107). At baseline, the all-group mean ADHD Index of Conners Adult ADHD Rating Scale score was 20.6, which improved to adjusted means of 14.2 for the GPT arm and 14.7 for the CM arm at follow-up with no significant difference between groups (difference, -0.5; 95% CI, -1.9 to 0.9; P?=?.48). The adjusted mean decreased to 13.8 for the MPH arm and 15.2 for the placebo arm (difference, -1.4; 95% CI, -2.8 to -0.1; P?=?.04). As in the core study, MPH was associated with a larger reduction in symptoms than placebo at follow-up. These results remained unchanged when accounting for MPH intake at follow-up. Compared with participants in the CM arm, patients who participated in group psychotherapy were associated with less severe symptoms as measured by the self-reported ADHD Symptoms Total Score according to the Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM-IV) of Conners Adult ADHD Rating Scale (AMD, -2.1; 95% CI, -4.2 to -0.1; P?=?.04) and in the subscale of reducing pure hyperactive symptoms, measured via the Diagnostic Checklist for the diagnosis of ADHD in adults (AMD, -1.3; 95% CI, -2.8 to 0.1; P?=?.08). Regarding the Clinical Global Impression scale assessment of effectiveness, the difference between GPT and CM remained significant at follow-up (odds ratio, 1.63; 95% CI, 1.03-2.59; P?=?.04). No differences were found for any comparison concerning depression as measured with the Beck Depression Inventory. Conclusions and Relevance:Results from COMPAS demonstrate a maintained improvement in ADHD symptoms for adults 1.5 years after the end of a 52-week controlled multimodal treatment period. The results indicate that MPH treatment combined with GPT or CM provides a benefit lasting 1.5 years. Confirming the results of the core study, GPT was not associated with better results regarding the primary outcome compared with CM. Trial Registration:isrctn.org Identifier: ISRCTN54096201.

Project description:OBJECTIVE:To examine status of children with autism spectrum disorder (ASD) 10 months after a 34-week clinical trial of atomoxetine (ATX) and parent training (PT). METHODS:In a 2?×?2 design, 128 children with ASD and attention-deficit/hyperactivity disorder (ADHD) were randomly assigned ATX, PT+placebo, PT+ATX, or placebo alone. PT was weekly for 10 weeks, and then monthly. ATX/placebo was titrated over 6 weeks [?1.8?mg/kg/d], and then maintained until week 10. Responders continued to week 34 or nonresponse. Placebo nonresponders had a 10-week ATX open trial; ATX nonresponders were treated clinically. All continued to week 34. With no further treatment from the study, all were invited to follow-up (FU) at 1.5 years postbaseline; 94 (73%) participated. Changes from Week 34 to FU and from baseline to FU were tested by one-way analysis of variance or chi-squared test. PT versus no PT was tested by chi-squared test, Fisher's exact test, Welch's t-test, Student's t-test, and Mann-Whitney's U test. RESULTS:For the whole sample, the primary outcomes (parent-rated ADHD on the Swanson, Nolan, and Pelham [SNAP] scale and noncompliance on the Home Situations Questionnaire [HSQ]) deteriorated mildly from week 34 to FU, but were still substantially better than baseline (SNAP: t?=?12.177, df?=?93, p?<?0.001; HSQ: t?=?8.999, df?=?93, p?<?0.001). On the SNAP, 61% improved ?30% from baseline (67% did at week 34); on noncompliance, 56% improved ?30% from baseline (77% did at week 34). Outcomes with PT were not significantly better than without PT (SNAP p?=?0.30; HSQ p?=?0.27). Originally assigned treatment groups did not differ significantly. Only 34% still took ATX; 27% were taking stimulants; and 25% took no medication. CONCLUSIONS:The majority retained their 34-week end-of-study improvement 10 months later, even though most participants stopped ATX. For some children, ATX continuation may not be necessary for continued benefit or other drugs may be necessary. Cautious individual clinical experimentation may be justified. Twelve sessions of PT made little long-term difference. ClinicalTrials.gov Identifier: Atomoxetine, Placebo and Parent Management Training in Autism (Strattera) (NCT00844753).
