Functional connectivity is assessed using a form of cross-correlation analysis that quantifies how much the entire BOLD timeseries in different brain regions are similar to one another. Our a priori treatment target brain regions are the superior frontal sulcus and mid-lateral prefrontal cortex region of interest. Brain activity and functional connectivity specifically to these regions represent the primary outcome measures of the study.","Change in fMRI measurements from baseline assessment versus 5 weeks at the conclusion of training",{"measure":14,"description":15,"timeFrame":16},"Experimental executive working memory training tasks - Reaction Time","Reaction time (RT) from training tasks of executive working memory. These are experimental, non-published tasks that were tested in this project for the first time in Phase I: Updating (removal then replacement of stimuli by new information to be maintained in working memory), Shifting (refocusing selective attention on different stimuli held concurrent in working memory without altering contents), distractor Filtering (inhibiting irrelevant information) and Suppression (resolution of proactive interference from initial stimuli to be able to respond optimally to control trials). Trial structure and duration are similar across these tasks. The tasks record RT in milliseconds.

This study will recruit n=130 adolescents, n=90 ADHD, 40 non-ADHD. The ADHD group will be randomized to a 'sham training' placebo or to train 4 times each week using 4 different EWM exercises that have been combined into the format of a typical cognitive training intervention. Exercise difficulty levels in the active intervention will increase across 5 weeks to continually challenge EWM ability. EWM training will use a novel, remotely-supervised 'at home' computerized training approach that was developed in the Phase I study. This study will attempt to establish a convincing link between the hypothesized targets found in Phase I and ADHD symptom expression. It also will characterize ADHD brain activity or EWM ability changes relative to typical levels seen in the n=40 non-ADHD control group.",[40,46],{"label":41,"type":42,"description":43,"interventionNames":44},"ADHD EWM","EXPERIMENTAL","Participants will receive EWM training sessions.",[45],"Behavioral: EWM Training",{"label":47,"type":48,"description":49,"interventionNames":50},"ADHD Placebo","PLACEBO_COMPARATOR","Participants will receive placebo training sessions.",[51],"Behavioral: Placebo Training",[53,58],{"type":54,"name":55,"description":56,"armGroupLabels":57,"otherNames":28},"BEHAVIORAL","EWM Training","Training tasks will target Executive Working Memory areas of the brain.
