About our Diagnostic Evaluation

We developed our Diagnostic Evaluation with one goal in mind: to offer a completely confidential mental health assessment that can support an ADHD diagnosis.

In late 2024, we conducted a clinical study comparing our Diagnostic Evaluation’s diagnosis of ADHD in adults to the current standard of care — a clinical interview.

“This validation confirms that patients can rely on the accuracy of their online evaluation, knowing their path forward is based on trusted clinical evidence.”

Barry K. Herman, MD, MMM, Chief Medical Officer

What does it mean to be clinically validated?

For patients struggling with undiagnosed or undertreated ADHD, finding valid and accessible assessment and treatment can be challenging. While telehealth offers affordable care, concerns about the accuracy of online assessments have persisted.

Our clinical study, published in the Journal of Clinical Psychiatry in October 2025, demonstrates that our Diagnostic Evaluation is as effective as traditional methods in diagnosing ADHD in adults—paving the way for telehealth to help more patients take control of their lives.

“This study shows that technology can expand access to trusted mental health care. Patients no longer have to choose between convenience and quality — they can have both, and on their own terms.”

Keith Brophy, CEO

Getting clarity shouldn’t be complicated

The Mentavi Mental Health Diagnostic Evaluation is clinically validated for diagnosing ADHD in adults,  built on the same science and standards used in traditional, in-person assessments, but delivered through a digital, clinician-reviewed model.

In this video, Mentavi Health Chief Medical Officer Dr. Barry K. Herman explains how the evaluation works, what clinical validation really means, and why this milestone matters for making quality mental healthcare easier to access for everyone.

He’s joined by Mentavi Health CEO Keith Brophy, who shares how this groundbreaking study reinforces Mentavi’s mission to combine clinical rigor with innovation, expanding access while keeping human expertise at the center of care.

Curious about stimulant or non-stimulant approaches?

If you’re navigating ADHD or other mental health challenges, you have options. At Mentavi Health / ADHD Online, we assess what works for you. 
Some may start with non-medicated approaches like coaching or therapy.  In other cases, patients may explore medication treatment paths when warranted by diagnosis. For some diagnosed with ADHD, the treatment clinician may work with the patient to determine if stimulant approaches work best for them. Stimulant approaches are certain medications under medical treatment that are generally Class II controlled substances. Non-stimulant options are another approach that can work for many.  Medication approaches can be used in tandem with coaching or therapy. 
 
The key is starting with our diagnostic evaluation, which is reviewed by a qualified healthcare professional. Getting clarity on what you’re experiencing is the first step toward feeling more in control. From there, you and your treatment team can determine the best path—whether that’s coaching, therapy, medication, or a combination that works for your life. 
 
If you’re not feeling right, let us walk alongside you by starting with the diagnostic evaluation.
