Here is their safety and warnings section disclosing that. It's really interesting because of how they're presumably required by law to make a CVS-receipt-length FDA medicine warning but all the dangers are for playing a video game. I think it's pretty cool to see how effective the FDA's procedures are at capturing your concerns, through forcing them to be transparent

# Indications:
> EndeavorRx is a digital therapeutic indicated to improve attention function as measured by computer-based testing in children ages 8-17 years old with primarily inattentive or combined-type ADHD, who have a demonstrated attention issue. Patients who engage with EndeavorRx demonstrate improvements in a digitally assessed measure, Test of Variables of Attention (TOVA®), of sustained and selective attention and may not display benefits in typical behavioral symptoms, such as hyperactivity. EndeavorRx should be considered for use as part of a therapeutic program that may include clinician-directed therapy, medication, and/or educational programs, which further address symptoms of the disorder.

# Safety:
> No serious adverse events were reported. Of 342 participants who received AKL-T01 in the two clinical trials supporting EndeavorRx authorization for age ranges 8-17, 17 participants (4.97%) experienced treatment-related adverse events (TE-ADE) (possible, probable, likely). TE-ADEs reported at greater than 1% across the studies include: frustration tolerance decreased (2.34%) and headache (1.17%). Other adverse events occurred less than 1% and included dizziness, emotional disorder, nausea, and aggression. All adverse events were transient and no events led to device discontinuation. Across other studies in children and adolescents with ADHD, rates of adverse events were similarly low (<10%) and no Serious Adverse Events have been reported. All reported adverse events across all clinical trials resolved at the end of treatment. Users should consider the totality of evidence presented along with their health care provider when considering incorporating AKL-T01 into their treatment plan.

If the problem persists contact your child’s healthcare provider. If your child experiences a seizure stop the treatment and contact your child’s healthcare provider.
