How it Works

Refer Your Patient

Use our secure referral form to provide the patient’s name, email, and your contact details.  Select if the referral is for Snapshot, Diagnostic Evaluation, or both. 

1

Patient Completes the Assessment

Diagnostic Evaluation

Patients receive a secure email invitation and complete the Diagnostic Evaluation at their own pace (typically 60–90 minutes).

Snapshot 

Patients receive a secure email invitation and complete the Snapshot at their own pace (typically 5-10 minutes).

Both Assessments 

Patients receive two separate secure emails with an invitation and instructions to complete the assessments at their own pace. They are instructed to complete the Snapshot first.

2

Clinical Review

A licensed psychologist from Mentavi Health reviews each Diagnostic Evaluation submission and prepares a comprehensive report.

The Snapshot is a self-assessment tool, evaluated and scored through the use of a proprietary scoring system.

3

Results Delivered to Your Patient's Email

Within five days, the patient will receive an email notification to view their Diagnostic Evaluation Report in the portal. A PDF version of the report is sent directly to your team for review and care coordination.

The results of the Mental Wellness Snapshot are available immediately after a patient completes the assessment. An email is sent to the patient prompting them to review their Snapshot results in the ADHD Online patient portal.

Coordinate the Next Step

Once the reports are received, review the findings with your patient and determine the next steps. Use the results to inform treatment planning, including medication management, therapy, or integrated 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.
There may be a brief delay in service today between 12:30 PM and 1:30 PM ET. Thank you for your patience — we look forward to assisting you shortly.
