NCT04002167

Brief Summary

The proposed study is to test and validate a novel intervention that integrates computerized cognitive training with real-time neuromonitoring and neurofeedback to enhance working memory by probing the individualized neural systems underlying working memory. We will test the proposed intervention on children with ADHD with working memory deficits. The R61 proof-of-concept phase will assess the target engagement, effective dose and feasibility.

Outcome Measures

Primary Outcomes (2)

  • Change in Target Frontal-parietal Activity

    Change in activity in the target frontal-parietal network measured by functional near infrared spectroscopy (fNIRS) during an N-back working memory task. A general linear model is applied to recorded signal and the beta coefficients from the model are extracted as a proxy for brain activity in fronto-pariteal network which subserves working memory function. There is no established population mean for beta coefficient of brain activity. Higher (lower) beta coefficients reflect higher (lower) activation in the target brain network. A positive change indicates increased brain activity. Increased frontal-parietal activity reflects better engagement of this brain network during working memory performance.

    baseline and 6 weeks

  • Change in Working Memory Performance

    Accuracy in an N-back working memory task was calculated as the percentage of correct responses to target stimuli.

    baseline and 6 weeks

Secondary Outcomes (5)

  • Change in Behavior Rating Inventory of Executive Function (BRIEF), Working Memory T-score

    baseline and 6 weeks

  • Change in Wide Range Assessment of Memory and Learning 2 (WRAML-2), General Memory Index Score

    baseline and 6 weeks

  • Change in Conners 3rd Edition ADHD Index Score

    baseline and 6 weeks

  • Change in Conners 3rd Edition Inattention T-score

    baseline and 6 weeks

  • Change in Developmental NEuroPSYchological Assessment II (NEPSY-II) Composite Score

    baseline and 6 weeks

Other Outcomes (3)

  • Change in Continuous Performance Test (CPT) Accuracy

    baseline and 6 weeks

  • Change in California Verbal Learning Test - Children's Version (CVLT-C) Score

    baseline and 6 weeks

  • Change in Parent Stress Index 4th Edition (PSI-IV)

    baseline and 6 weeks
