ADHD Misdiagnosis: Why Our Systems Fail Neurodivergent Minds and What We Must Do Now

I had a conversation recently that truly solidified something I've been seeing for years in my practice at Gateway Behavioral Health Consultants (GBHC): our current systems—from education to mainstream medicine—are failing to see, understand, and properly support neurodivergent individuals, especially those in diverse populations.

And I'm not talking about a small oversight. I’m talking about a crisis in care, and it stems from a profound and dangerous gap in professional training. As a psychologist and business owner, I value clear and assertive communication, and right now, the system's communication is failing our clients.

The Problem: A Dangerous Gap in Training and Understanding for ADHD Misdiagnosis

Like many of my colleagues, I was trained on the textbook definitions of conditions like ADHD—what they look like on paper, according to the DSM. But the real world is infinitely more complex. The variations in how these conditions present are vast, subtle, and often completely missed.

Looking back at my own training, I was taught diagnostic criteria, but not the variations. The way I’ve learned what neurodivergence truly looks like has been through:

• Self-Driven Research and Continuing Education: I had to actively seek out training because it was an area of personal and professional interest.

• Personal Connection: Many of the most informed providers in this field are passionate because they, or someone they love, are neurodivergent themselves. This personal motivation drives them to better understand the unique challenges and perspectives of this population, which is fantastic.

While I applaud the providers who seek out this specialized knowledge, it creates a serious problem: only those who are already seeking out specialized professionals are getting the support they need.

The vast majority of professionals who serve as our frontline—our pediatricians, general practitioners, and teachers—are simply not as well-informed as specialists. We are not equipping them with the knowledge to identify neurodiversity in:

• Gifted individuals

• Women

• Diverse ethnic and racial populations

The Pain of Being Unseen

The consequences of this systemic failure are devastating. I serve many neurodivergent women who were not diagnosed until much later in life. Their early years were spent masking, camouflaging, and trying to force themselves to operate in ways their brains simply aren't wired for. They felt different and felt this intense pressure to fit in.

This pressure to fit in and to make their brains do what they "should" often results in severe secondary mental health issues like anxiety, depression, and even trauma. The system is built to identify and treat those symptoms, but not the underlying neurotype that created them.

A Pervasive Example of ADHD Misdiagnosis

One of the most common and heartbreaking patterns I see involves women who have been struggling for years, often presenting with chronic anxiety and depression which turns out to be an ADHD misdiagnosis. They receive treatment—medication, traditional talk therapy—but never quite get better. Why? Because the underlying engine driving their distress, the foundational source of their struggle, is undiagnosed ADHD.

• Their anxiety isn't a disorder in itself; it’s a symptom of a brain constantly trying to keep up with neurotypical demands, manage severe executive function deficits, or recover from intense social masking.

• Their depression isn't merely chemical; it’s burnout and the accumulated grief of feeling fundamentally "wrong" or "broken" in the world.

They have gone through years of not getting the appropriate help because the focus was on treating the secondary symptoms, not identifying the primary neurodevelopmental cause. This lack of proper identification means they never receive the targeted, neuro-affirming support they desperately need to truly understand themselves and thrive.

Why Early Identification Matters to Everyone

If we can help identify these individuals sooner, get them diagnosed, and help them understand how their brain works, we can encourage them to embrace those strengths and differences.

Correct, early identification would:

• Significantly improve mental health outcomes overall.

• Decrease pain and suffering for individuals.

• Reduce stress and utilization across our entire society: special education systems, teachers, the general workforce (decreasing absences), and mental health services.

• Avoid decades of unlearning and chronic pain that results from navigating a world without a roadmap for your own mind.

The Solution: A Three-Pronged Approach to Advocacy and Change

As professionals in mental health, education, and medicine, we must move beyond simply wishing for change. We must become the advocates that create it. Advocacy, in this context, is a practical application of our commitment to Excellence—the pursuit of high-quality, evidence-based care.

1. Revamp Our Training Systems: Beyond the DSM

Change starts at the foundation. We absolutely must overhaul how we train future teachers and medical professionals.

A. Overhauling Professional Training

• Go Beyond Diagnostic Criteria: We cannot limit training to only the textbook criteria. We need to teach the subtle, real-world, and diverse presentations of ADHD, including masking behaviors.

• Prioritize Identification: This doesn't require a complete redesign of every curriculum, but it requires prioritizing this knowledge. A few extra specialized classes, dedicated seminars, or comprehensive training modules would build a crucial framework for understanding that neurodiversity presents differently.

• Train the Trainers (Mental Health Professionals): We need to start by making this knowledge the standard in graduate schools for mental health providers, not just a niche interest. The more experts we train, the better equipped we will be to train the rest of the community—our teachers, doctors, and nurses.

B. Continuous, On-Site Education

• We need people who are experts in this area to go into schools, hospitals, and medical practices and provide ongoing training to help staff recognize what neurodiversity looks like now, continuing the conversation from their initial education.

2. Develop Practical Screening Tools for the Front Lines

Medical providers and educators are overloaded; they need tools that integrate seamlessly into their busy practices. We have quick, standardized tools for anxiety and depression—like the GAD-7 or PHQ-9. We need the same for neurodiversity.

• Quick Neurodiversity Screeners for Medicine: We must develop brief screening measures—perhaps 10 questions—specifically designed for diverse and highly-masking populations. These need to be quick, practical tools that can be used effectively during a brief medical appointment.

  • These tools should look at common neurodivergent issues, such as executive functioning challenges, subtle social challenges, and masking behaviors.

• Classroom Checklists for Educators: For teachers, it might be a structured, easy-to-use screening tool for parents or a simple checklist for their classroom. The goal is to give educators a framework to identify students who may need further assessment without adding significant stress or complexity to their day.

3. Demand Systemic Change: Access to Care is a Right, Not a Privilege

This is the most critical and often the most overlooked part of our advocacy: access to services. All the training and screening in the world is useless if a person cannot get a diagnosis from a qualified professional at a reasonable cost. This is where the core value of Accessibility must be applied with force.

A. Address the Provider Shortage and Funding Crisis

• The Privilege of Diagnosis: Currently, getting a comprehensive, qualified diagnosis is a privilege because we simply do not have enough providers who understand ADHDin diverse populations, and funding in this area is extremely limited.

• The Real-World Impact: I recently had a colleague reach out looking for a well-versed provider to diagnose a 45-year-old woman using her Medicare benefits. Providers who accept Medicare for adult diagnoses and are well-versed in complex presentations are severely limited in the St. Louis/Missouri area. The scarcity is real.

B. Challenge the Insurance Barriers

• The Impossible Evaluation Time: The way insurance works is fundamentally broken for complex cases. We are often allotted a maximum of 7 hours to test and diagnose a neurodivergent case with multiple co-occurring conditions like anxiety, depression, and trauma.

• The Reality of Comprehensive Care: A thorough, accurate evaluation for a neurodivergent woman—one that addresses her complex history, performs the necessary testing, and writes a comprehensive report and roadmap—can take anywhere from 10 to 16 hours. I, like many sticklers for thoroughness, refuse to rush an evaluation that has been dismissed by other providers. We must take the time to validate their concerns and provide a comprehensive roadmap.

C. Advocate for Policy and Law

• If we are not talking to lawmakers, if we are not advocating for change on a systemic level, it doesn't matter how well we identify people. If people don't have access to a diagnosis at a reasonable cost, we are not serving anyone. We need more funding, and we need insurance policies that reflect the complexity and time required for quality diagnosis and subsequent care.

A Final Call to Action

This work is foundational to our value of Empowerment—it is a direct extension of our desire to help people grow and give them the tools to succeed.

If you are a professional—a teacher, administrator, doctor, nurse, or mental health provider—I urge you to make this commitment today: Start educating yourself and your staff.

It doesn't have to be a grand gesture. You can start today:

• Seek Out Training: Reach out to providers well-versed in neurodiversity and diverse populations to arrange training for your staff or practice.

• Self-Educate: Dedicate time to reading books, listening to podcasts, or following neuro-affirming neurodivergent creators on social media. Start to educate yourself on the diverse presentations.

You can do little things in your day-to-day practice that will make a huge difference. Your awareness is a catalyst. You will be amazed at the gratitude these individuals and their families will have for just your awareness of their unique strengths and challenges.

Let's prioritize Inclusivity by truly seeing and understanding every person who walks through our doors. Let's move beyond the textbooks and advocate for a system that serves all minds.
