Signs an ADHD evaluation might be worth considering
Persistent focus and follow-through difficulty
Starting tasks is easy; finishing them is hard. Attention drifts from the important to the immediate. Notes pile up. Tabs multiply. Meetings end and the action items disappear. An ADHD evaluation clarifies whether the pattern is ADHD, executive function variance, or something else that responds to a different intervention.
Time, organization, and follow-through challenges
Chronic lateness despite trying to be early. Deadlines that arrive faster than expected. Paperwork that sits. The home or office surface that never quite clears. These are recognized features of adult ADHD and are evaluated alongside attention, working memory, and processing speed in the standardized battery.
Restlessness and hyperactivity in adults
Inner restlessness more than the visible fidgeting often described in childhood ADHD. Trouble sitting through meetings. Talking through other people. Quick decisions you immediately regret. These adult presentations are evaluated in the standardized battery alongside the inattentive features.
The high-functioning ADHD pattern
Adults often compensate for ADHD with intelligence, over-preparation, anxiety-driven structure, or long hours. The pattern works until it doesn’t — usually around a promotion, parenting load, or graduate-level demand. Testing clarifies what’s underneath the compensation and what accommodations would actually help.
Suspected ADHD-anxiety or ADHD-depression overlap
ADHD frequently co-occurs with anxiety or depression. The presentation often looks more like the anxiety or depression than like ADHD. A comprehensive evaluation distinguishes the layers and identifies which condition is primary — which changes treatment recommendations significantly.
What the ADHD evaluation includes
Clinical diagnostic interview
(Structured history-taking + DSM-5 ADHD criteria)
A structured clinical interview gathers developmental history, current functioning, and DSM-5 ADHD symptom criteria. The interview anchors the rest of the testing — the standardized measures are interpreted in the context of the developmental and current presentation, not in isolation.
Standardized cognitive testing
(Attention, working memory, processing speed)
Standardized cognitive measures evaluate attention (sustained, selective, divided), working memory, processing speed, and inhibitory control. These are the cognitive substrates affected in ADHD and are the most diagnostically informative measures alongside the rating scales.
Behavior rating scales (self + collateral)
(Self + parent or partner ratings as appropriate)
Standardized ADHD rating scales (self-report and collateral from a parent, partner, or close other) sample real-world functioning across settings. Collateral ratings are particularly important for the developmental history piece, since adult ADHD requires evidence the pattern was present before age twelve.
What the integrated report produces
Diagnostic clarity
A clear diagnostic conclusion: ADHD (specify presentation), executive function variance below clinical threshold, anxiety-driven attentional issues, or another pattern. The report explains the reasoning — not just the conclusion — so the diagnosis travels well to psychiatrists, schools, employers, or licensing boards.
Why a thorough differential matters
Some ADHD presentations are unmistakable; many are not. A comprehensive ADHD evaluation distinguishes ADHD from anxiety-driven attentional issues, depression-related concentration problems, sleep-deprivation patterns, or executive function variance below clinical threshold. The differential matters because the treatment recommendations diverge.
What the accommodation language enables
If ADHD is diagnosed, the report includes specific accommodation recommendations grounded in the testing data — appropriate for school (504 plans, IEP referrals), college (disability services), workplace (ADA accommodations), or licensing board (extended time on professional exams). The language is purpose-built for the destination, not generic.
From first call to integrated report
Intake
You reach out via the form or call (630) 474-1006. We schedule a 55-minute intake to gather developmental history, current concerns, and the question the evaluation needs to answer. The intake anchors the testing battery.
Testing
Testing typically runs across two to three appointments — clinical interview, standardized cognitive measures, rating scales, and collateral input as appropriate. Joe or Tim conducts the testing directly. Standardized administration, clean data.
Integrated Report
A written report integrating the interview, cognitive measures, rating scales, and collateral data. Diagnostic conclusion, reasoning, accommodation recommendations. Typical turnaround is 2 to 4 weeks. Includes a feedback session to walk through the findings.

ADHD Evaluation for Adults
Inherited patterns
Many adults with ADHD compensated through intelligence, over-preparation, or anxiety-driven structure for years before the system stopped scaling. The pattern looks like “finally falling apart” but it’s actually “running out of cognitive bandwidth to keep compensating.” The testing clarifies what was always there.

High-achiever cost
ADHD presentations in women are systematically under-diagnosed. The hyperactive piece is often internal — restless mind rather than visible fidgeting. The inattentive piece gets coded as anxiety, dreaminess, or laziness. A comprehensive ADHD evaluation specifically attends to these under-recognized patterns.
Unprocessed life transitions
Life transitions that change executive function load — graduate school, parenting, new leadership role, demanding career — often surface ADHD that had been managed before. The trigger isn’t the cause; the wiring was always there. Testing confirms and clarifies.
Neurobiological wiring
ADHD is one of the most heritable psychiatric conditions. If a parent or sibling has ADHD, the family resemblance is informative for the differential. A comprehensive evaluation maps the wiring you have, with specific accommodation recommendations that match it.

Frequently asked questions about ADHD testing
Can a therapist diagnose ADHD?
At our practice, ADHD is evaluated by licensed psychologists (PsyD/PhD) qualified to assess and diagnose. A proper evaluation uses a clinical interview, history, and validated measures, not a single quick screen.
How much does an ADHD evaluation cost?
ADHD testing is priced as a package based on the scope of the evaluation, so cost varies. We’ll give you a clear quote when you reach out, along with what your insurance may cover. See our Insurance & Fees page.
How long does an ADHD evaluation take?
Start to finish, expect about a month: the intake, the testing itself, and a feedback session where we walk you through results and practical next steps.
Do you evaluate adults and teens for ADHD?
Yes, both adults and adolescents. We use interview, history, rating scales, and testing where appropriate to clarify attention, executive function, and the impact at work or school.
Will insurance cover ADHD testing?
Sometimes; it depends on your plan and the reason for testing. We’re in-network with Aetna, BlueCross and BlueShield, Medicare, and UnitedHealthcare and bill out-of-network benefits on your behalf. Reach out and we’ll help you check. See our Insurance & Fees page.
Can I get an ADHD evaluation without full psychological testing?
Yes — we offer both paths. A focused diagnostic mental health evaluation uses a structured clinical interview and validated rating scales (typically 2–4 clinician hours) to clarify whether ADHD fits the picture and to address differentials like anxiety, depression, or sleep-related attention issues. It’s the right fit when you want diagnostic clarity for treatment planning, a second opinion on an existing diagnosis, or a foundation to coordinate with a prescriber — but you don’t need formal accommodation documentation. Full ADHD testing (6–10 clinician hours) adds standardized cognitive, attention, and executive function measures, and is the right path when school 504 plans, college disability services, workplace ADA accommodations, or licensing-board extended-time requests are part of the goal. We recommend the right level when you book.
Will the report support medication referral to a psychiatrist?
Yes. If ADHD is diagnosed, the integrated report provides the diagnostic clarity a psychiatrist needs for medication consideration. We don’t prescribe — we provide the diagnostic foundation, and you take the report to your psychiatrist or primary care provider for the medication conversation.
Will the report support school or workplace accommodations?
Yes. If ADHD is diagnosed, the report includes specific accommodation recommendations appropriate for the destination — school 504 plans, college disability services, workplace ADA accommodations, or licensing board extended-time requests on professional exams. The language is purpose-built.
What if I don’t click with my testing clinician?
Testing is conducted by Joe or Tim — both licensed psychologists. We match you to the clinician whose schedule aligns with your timeline, with all standardized administration conducted directly by your matched psychologist — not by technicians or junior staff.
Can ADHD testing be done via telehealth?
The standardized testing portion is conducted in-person at our Naperville office to preserve administration validity. The intake interview and the feedback session can be conducted via secure Illinois telehealth. We’ll structure the schedule at the intake.
