Think You Might Have ADHD? Get the Full Picture First.
By: Gina Romero, LICSW, LCSW, ADHD Specialist
Getting the right diagnosis isn't just about confirming what you suspect.
If you've been wondering whether you have ADHD, you're not alone. ADHD awareness has grown significantly in recent years, and more adults than ever are recognizing patterns in themselves that finally have a name. That's a good thing. But the path from "I think I might have ADHD" to an accurate diagnosis is more nuanced than most people realize, and getting it wrong has real consequences.
This post is for anyone who suspects they have ADHD, has already been diagnosed and isn't sure the diagnosis fits, or is trying to figure out what kind of evaluation they actually need.
Executive Function Deficits Don't Come From ADHD Alone
You’ve been browsing social media, and you’ve discovered you can relate to all of the posts about ADHD. You’ve decided to learn more about getting assessed. Your friends agree, and they’ve encouraged you to pursue a formal assessment. Let me tell you what your supportive friends won’t: executive function deficits (trouble with task initiation, organization, follow-through, time management, working memory) are not unique to ADHD. They show up across a wide range of diagnoses. Here are some examples:
Anxiety can make it nearly impossible to start tasks, not because of a dopamine regulation issue, but because of avoidance, overwhelm, and fear of failure.
PTSD affects concentration, memory, and the ability to regulate attention in ways that look almost identical to ADHD on the surface.
Autism, particularly in people with a Pathological Demand Avoidance (PDA) profile, can present with significant task initiation difficulties and demand avoidance that mirrors ADHD inattentive type closely.
Mood disorders (depression, bipolar disorder, cyclothymia) all affect energy, motivation, concentration, and follow-through in ways that can look like ADHD, especially during depressive or mixed episodes.
Sleep disorders, thyroid conditions, and chronic stress can also produce symptoms that look like ADHD without any of the underlying neurodevelopmental profile.
The treatment for each of these conditions is different. And treating the wrong thing doesn't just fail to help. It can actively make things worse.
The Wrong Treatment Can Make Things Worse
I want to share something I see regularly in my clinical work~
I frequently receive referrals from well-meaning therapists and other providers who assessed a client for executive function deficits, suspected ADHD, and sent them my way for further evaluation. When I complete a more comprehensive assessment, we often discover that the executive function deficits are being driven by something else entirely, most commonly, anxiety.
When a client with severe anxiety takes a stimulant medication for ADHD, their anxiety can feel significantly worse. Stimulants can amplify anxiety, increase heart rate, disrupt sleep, and create a cascading set of symptoms that the client understandably interprets as evidence that they're broken, unfixable, or just not capable of getting better.
The same principle applies to treatment approach. If someone is autistic with a PDA profile and we're using a CBT-based approach to address task initiation and completion (an approach that relies heavily on structure, demands, and cognitive reframing) we may be using a framework that is fundamentally incompatible with how that person's brain and nervous system works. It won't help, and it can reinforce the belief that the problem is them, that they're not trying hard enough, that they're resistant to help. That belief pushes people further from their goals and further from treatment. Getting the diagnosis right is the foundation everything else is built on.
A Note on Diagnostic Criteria
Having some symptoms of ADHD does not mean you meet the diagnostic criteria for ADHD.
The DSM-5 criteria for ADHD require a specific number of symptoms from the inattentive and/or hyperactive-impulsive categories, present in multiple settings, causing clinically significant impairment, with onset before age 12, and not better explained by another condition. Having two or three symptoms of inattentive type (difficulty sustaining attention, losing things, being easily distracted) does not meet the threshold for diagnosis. Most people, neurotypical or not, experience some of these symptoms some of the time.
A thorough evaluation looks at severity, duration, context, impairment, and the full diagnostic picture.
Three Paths to an ADHD Diagnosis
If you've decided you want a formal evaluation, here's a breakdown of your options.
Path 1: Full Neuropsychological Evaluation
A comprehensive neuropsychological evaluation is the most thorough option available. Conducted by a licensed psychologist (PhD or PsyD), it typically involves several hours of standardized testing covering cognitive functioning, attention, memory, processing speed, executive function, and more. It also usually includes clinical interviews, behavioral rating scales, and a review of records.
Pros: The most comprehensive picture available. Can identify or rule out multiple conditions simultaneously, including learning disabilities, autism, mood disorders, and ADHD. Results are detailed and defensible for school accommodations, workplace accommodations, or legal purposes.
Cons: Expensive. Frequently not covered by insurance (especially adults), or only partially covered. Wait times can be long. The depth of the evaluation can feel overwhelming for some people.
Best for: People who want the most thorough answer possible, who need documentation for formal accommodations, or whose presentation is complex enough that a briefer evaluation might miss something.
Path 2: Comprehensive Testing With a Trained Master's-Level Therapist
A licensed therapist with specialized training in ADHD assessment can conduct a thorough diagnostic evaluation that goes well beyond a symptom checklist in most states. This typically includes clinical interviews, standardized rating scales, collateral information where possible, and a differential diagnosis process that considers other explanations for the symptoms.
Pros: More accessible than a full neuropsychological evaluation in terms of cost and wait time. A good evaluator will assess for co-occurring conditions, not just ADHD. You can often continue working with the same clinician after the evaluation, which provides continuity of care.
Cons: Does not include the full battery of cognitive testing that a psychologist provides. May not be sufficient for all accommodation documentation purposes, depending on the institution or employer.
Best for: Adults who want a thorough, clinically grounded evaluation without the cost and time commitment of a full neuropsych, and who want their assessment to consider the full diagnostic picture.
One important note: Many master's-level evaluators do not assess for autism in most states. Nevada doesn’t allow masters-level therapists to diagnose autism, but Washington does. If autism is a possibility for you, ask explicitly whether it will be included in the evaluation before you begin.
Path 3: Evaluation Through a Prescriber
A psychiatrist or psychiatric nurse practitioner can conduct an ADHD evaluation and, if appropriate, discuss medication options. This is a legitimate and often insurance-covered pathway to diagnosis, and it does not require you to commit to ongoing treatment with that provider.
Pros: Usually covered by insurance. Can be a faster route to diagnosis and medication if that's the goal. You are not obligated to continue seeing that provider after the evaluation.
Cons: Prescriber evaluations tend to be very short and more symptom-focused than evaluations conducted by psychologists or therapists. They are less likely to include a thorough differential diagnosis process, due to time constraints. Most prescribers do not assess for autism, and sometimes they don’t comprehensively assess for anxiety, PTSD, or mood disorders as potential alternative explanations for the symptoms. If the picture is complex, a prescriber evaluation may miss it. This is more of a reflection of our broken medical system (and the barriers that it creates) than a reflection of any particular prescriber. I personally know some medication prescribers who are extremely thorough in their diagnostic process.
Best for: People who primarily want to explore whether medication is appropriate and who have a lower-complexity presentation. If you choose this path, consider pairing it with therapy to ensure the broader picture is being addressed.
Questions to Ask a Provider Before You Begin
Before you commit to an evaluation, here are some questions worth asking:
"What conditions do you assess for beyond ADHD?" A good evaluator should be looking at anxiety, mood disorders, trauma, and ideally autism as part of the differential. If the answer is "just ADHD," that's important information.
"Do you assess for autism?" Many providers don't, and autism (particularly in women and adults who masked well in childhood) is frequently missed. If this is a question for you, you need a provider who will address it directly.
"How do you distinguish ADHD from anxiety or trauma-related executive function deficits?" This question tells you a lot about how thorough and nuanced the evaluation will be. A strong evaluator will have a clear answer.
"What does the evaluation process look like, and what will I receive at the end?" You should expect a clinical interview, standardized measures, and a written report or at minimum a thorough verbal summary of findings and recommendations.
"What happens if the evaluation finds something other than ADHD?" You want a provider who is prepared to follow the data wherever it leads, not one who is working toward a predetermined conclusion.
