Outcome Measures
Primary Outcomes (1)
K-BRIEF-2 (Behavior Rating Inventory of Executive Function, Second Edition)
The K-BRIEF-2 consists of 63 items rated on a 3-point scale (Never, Sometimes, Often). The K-BRIEF-2 comprises 9 scales (Inhibit, Self-Monitor, Shift, Emotional Control, Initiate, Working Memory, Plan/Organize, Task-Monitor, Organization of Materials) organized under 3 index scores (Behavior Regulation, Emotion Regulation, Cognitive Regulation). The 9 scales collectively yield the Global Executive Composite (GEC), which reflects overall executive functioning. Higher T scores indicate greater executive function difficulties.

Study Arms (2)
The experimental group (immediate intervention)
EXPERIMENTALNDTx-02 + TAU for the first 6 weeks (stage 1), followed by TAU only for the following 6 weeks (stage 2).
The waitlist control group (delayed intervention)
OTHERTAU only during the first 6 weeks (stage 1), followed by NDTx-02 + TAU for the following 6 weeks (stage 2).
Interventions
NDTx-02 intervention: Participants will be provided with a tablet pre-installed with NDTx-02 and instructed to use the device five times per week for six weeks, for a total of 30 sessions.
TAU (Treatment-As-Usual): Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD)-related treatment/rehabilitation/education.
Eligibility Criteria
You may qualify if:
- Children and adolescents aged 5 to 12 years at the time of screening
- Diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD) or Autism Spectrum Disorder (ASD)\* by a psychiatrist according to DSM-5 diagnostic criteria
- \*For ASD, diagnosis can be supported by the Autism Diagnostic Interview-Revised (ADI-R) or the Autism Diagnostic Observation Schedule (ADOS), either version 1 or 2
- Full-Scale Intelligence Quotient (FSIQ) of 65 or higher
- Able to use the 'NDTx-02' installed on a tablet, alone or with the assistance of a guardian
- Able to comply with the recommended application schedule for the investigational device (6 weeks, 30 sessions, 5 times per week)
- Agree not to add or change any treatment/education/rehabilitation programs or medications, including Applied Behavior Analysis (ABA) or cognitive therapy, during the study period (continuation of pre-existing TAU \[Treatment-As-Usual\] is allowed)
- Participant and parent (or legal guardian) voluntarily decide to join the trial and provide written informed consent
- Participants willing to comply with the clinical trial procedures
You may not qualify if:
- A risk of clinically significant behavioral problems, emotion regulation problems, psychotic symptoms, self-harm, or other harm at a level that affects the treatment process
- Severe acute/chronic medical or mental illness
- Serious trauma or surgery performed within 4 weeks before the screening date
- Participants with other disabilities such as severe neurological diseases (e.g. brain lesions, mental disorders, etc.)
- Participants who are currently participating in another clinical trial or have participated in another clinical trial within 30 days before the screening date
- Change in the dosage or regimen of medications that may significantly affect cognitive function within 4 weeks prior to the baseline visit
- Change in participation in treatment/education/rehabilitation programs that may significantly affect cognitive function within 4 weeks prior to the baseline visit
- Participation in a clinical trial of, or prior experience using, cognitive improvement or daily living improvement software within 12 weeks prior to the baseline visit
- In other cases where the investigator determines that participation in the clinical trial is inappropriate due to ethical reasons or the possibility of influencing the results of the clinical trial
