ADHD Testing in Northbrook: What to Expect, Step by Step
If you're wondering whether you or your child has ADHD, a comprehensive evaluation answers the question properly — not with a five-minute checklist, but with objective testing that either confirms ADHD, rules it out, or uncovers what's actually going on. Here's exactly how the process works at our Northbrook office, and how to decide whether it's the right next step.
Who should consider ADHD testing?
For children and teens, common triggers are a teacher raising concerns about focus or impulsivity, homework battles that take hours for twenty minutes of work, strong ability with inconsistent output, or a pediatrician suggesting evaluation before considering treatment. Testing is also how families access formal school supports — a documented evaluation is typically required for a 504 plan or IEP.
For adults, it often starts with a pattern finally getting a name: chronic disorganization, jobs or projects that unravel at the follow-through stage, a lifetime of "so smart, if only they applied themselves," or recognizing your own struggles while your child gets diagnosed. Adult ADHD is real, common, and frequently missed — especially in women, where it tends to look like internal restlessness and overwhelm rather than hyperactivity.
Why a comprehensive evaluation beats a quick screening
A screening questionnaire at a doctor's office can suggest ADHD; it can't distinguish it from the conditions that mimic it. Anxiety disrupts concentration. Depression drains motivation. Learning disabilities make schoolwork torturous. Sleep problems wreck attention. A comprehensive evaluation tests these possibilities directly, which matters because the treatments differ — and because roughly half the ADHD picture is what else is going on alongside it. Getting the full picture once beats treating the wrong thing for years.
The process at Grand Oaks, step by step
1. Intake interview. You (and your child, if the evaluation is for them) meet with a licensed Psychologist to walk through history — development, school, work, medical background, and what prompted the evaluation. Rating forms typically go to people who see the day-to-day picture: parents, teachers, or a spouse.
2. Testing sessions. The core of the evaluation: standardized measures of attention, working memory, processing speed, and executive functioning, plus cognitive and academic measures where relevant. Testing is done in person at our Northbrook office, usually across one to two sessions of a few hours each. It's structured but not stressful — kids often describe it as "puzzles and games."
3. Scoring and integration. Your Psychologist scores everything against age-based norms and integrates test data, rating forms, history, and observations into a diagnostic picture. This is where a comprehensive evaluation earns its keep — the conclusion rests on converging evidence, not one questionnaire.
4. Feedback session. You meet to go through the results in plain language: what was found, what it means, and a concrete, prioritized plan — whether that's therapy, school accommodations, Cogmed working memory training, coordination with a prescriber about medication, or some combination.
5. The written report. You receive a full report documenting the findings — the document schools require for 504/IEP eligibility, colleges require for testing accommodations, and other providers use to coordinate care. With your consent, we can communicate directly with your child's school team.
Start to finish, most evaluations run two to four weeks depending on scheduling.
What it costs and what insurance covers
Coverage for psychological testing varies by plan more than almost any other service — some plans cover evaluations well, others require pre-authorization, and coverage can differ for the "learning disability" portion of an evaluation. Rather than quote a range that may not apply to you, our Intake Team verifies your specific testing benefits before anything is scheduled, so you know the real number up front. Self-pay options are available, and we provide a Good Faith Estimate as required under the No Surprises Act.
After the diagnosis: what happens next
A diagnosis is a starting line, not a label. Depending on the findings, next steps may include behavioral therapy and executive-functioning skill-building with one of our therapists, school accommodations backed by the report, parent coaching for younger children, and — where medication is worth considering — coordination with your pediatrician or a psychiatrist, with the evaluation giving the prescriber a far better starting point than a screening ever could. Our Northbrook office also offers Cogmed, a research-backed working memory training program that few North Shore practices provide.
Questions families ask about ADHD testing:
What ages do you test?
We evaluate children, adolescents, and adults. The test battery is tailored to age — a seven-year-old's evaluation looks very different from a forty-year-old's.
Does my child need to stop medication before testing?
Don't change any medication without talking to the prescriber. Discuss current medications with your evaluating Psychologist during intake — they'll advise on timing based on the referral question.
Can testing be done over telehealth?
The intake and feedback sessions can be remote, but the standardized testing itself is conducted in person at our Northbrook office to keep results valid.
Is it too late to test an adult?
No. Adults get evaluated every week, and a clear diagnosis in adulthood often reframes decades of self-blame into something workable.
