Primary Outcome Measures:
  • Demonstrate a difference in EVO cognitive measures between neuro-typicals and ADHD subjects [ Time Frame: Up to 12 months ]
    As a primary end-point, the study will aim to show a difference in cognitive measures between neuro-typicals and ADHD subjects.

  • Evaluate EVO safety [ Time Frame: Day 0 through Day 28 of the study ]
    Another objective of this study is to evaluate the safety of EVO game play based on treatment-emergent adverse events (TEAEs) that may occur during this 29 day period of time.

Secondary Outcome Measures:
  • EVO game play feasibility [ Time Frame: Up to 12 months ]
    Demonstrate the ability of ADHD and neuro-typical children to complete EVO in-clinic diagnostic assessment (DAY 0). Demonstrate compliance (measure behavioral play patterns) of ADHD and neuro-typical children during out-patient EVO game training period (DAY 1-27). Demonstrate the ability of ADHD and neuro-typical children to complete in-clinic EVO diagnostic assessment (DAY 28).

Other Outcome Measures:
  • Exploratory objective to evaluate improvements in cognitive function [ Time Frame: Up to 12 months ]
    An exploratory objective of this study is to investigate any improvements in cognitive function, as measured by EVO and standard cognitive assessments, that result from the 27 days of game training

Detailed Description:

A study in children ages 8 to 12 to assess EVO cognitive game play. The study examines two populations, children diagnosed with ADHD (ADHD and not on medication) and neuro-typical children. The investigators plan to evaluate 80 subjects (N = 40 per group) in three site locations over a 29 day study period. The 29 day study period includes 2 in-clinic sessions and 27 days of out-patient game play. During the 27 days of out-patient game play, the subjects will be instructed to play EVO 5 days per week for typically 30 minutes per day

The investigators' hypothesis is that EVO will be playable and interesting to ADHD children and cognitive measures, as captured by EVO, will show a difference between ADHD children and age-matched neuro-typical children.

  4. Baseline ADHD-RS-IV score <=13 (Neuro-typical Cohort), obtained at clinic
  5. Consistently off ADHD drug for 1 week. Drugs include: Pre specified, oral psychostimulants (ADDERALL XR® [mixed salts of a single-entity amphetamine product], VYVANSE® [lisdexamfetamine dimesylate], CONCERTA® [methylphenidate HCl], FOCALIN XR® [dexmethylphenidate HCl], RITALIN LA® [methylphenidate HCl extended-release], METADATE CD® [methylphenidate HCl, USP], or FDA-approved generic equivalents )for 1 month (Other than ADHD drud
  6. Consistently off Psychotropic drug for 1 month (Other than ADHD drug noted above)
  7. Ability to follow written and verbal instructions (English)
  8. Girls or Boys (Gender-matched - 30% girls minimum)
  9. Functioning at an age-appropriate level intellectually.
  10. Ability to comply with all the testing and requirements.

Exclusion Criteria:

  1. Current, controlled (requiring a restricted medication) or uncontrolled, comorbid psychiatric diagnosis with significant symptoms such as post-traumatic stress disorder, psychosis, bipolar illness, pervasive developmental disorder, severe obsessive compulsive disorder, severe depressive or severe anxiety disorder, conduct disorder, or other symptomatic manifestations that in the opinion of the Investigator that may confound study data/assessments (per MINI-Kid).
  2. Within the last 4 weeks, subject has entered or exited behavioral therapy. The subject should inform the Investigator if they intend to change their behavioral therapy during the 4 weeks of the study.
  3. Subject is currently considered a suicide risk in the opinion of the Investigator, has previously made a suicide attempt, or has a prior history of, or is currently demonstrating active suicidal ideation or self-injurious behavior (per C-SSRS).
  4. History of failure to respond to an adequate trial of 2 treatments for ADHD (consisting of an appropriate dose and adequate duration of therapy and failure in efficacy in the opinion of the Investigator).
  5. Motor condition that prevents game playing
  6. Recent history (within the past 6 months) of suspected substance abuse or dependence.
  7. History of seizures (exclusive of febrile seizures), a tic disorder, significant tics, or a current diagnosis of Tourette's Disorder.
  8. Taken part in a clinical trial within 30 days prior to screening.
  9. Diagnosis of color blindness
  10. Regular use of psychoactive drugs that in the opinion of the Investigator may confound study data/assessments.
  11. Any other medical condition that in the opinion of the Investigator may confound study data/assessments.
