Quick Answer: Adult ADHD Evaluation in NYC

A comprehensive adult ADHD evaluation takes 60 to 90 minutes and includes current symptoms, a developmental history establishing symptoms before age 12 (a DSM-5-TR requirement), impairment in at least two settings, and systematic screening for the conditions that mimic ADHD — sleep disorders, thyroid dysfunction, anxiety, depression, trauma, substance use, and autism. Rating scales inform but do not establish the diagnosis, and a 20-minute telehealth screen is not an evaluation. Dr. Ryan Sultan is a Columbia University psychiatrist and ADHD researcher in Chelsea, Manhattan.

Most people arriving here have already done the reading, taken an online quiz, and recognized themselves. The question is no longer might I have this — it's who can tell me properly.

What a real evaluation includes

1. Current symptoms. Inattention and hyperactivity-impulsivity as they present in adults, which looks different from the childhood picture. Adults are rarely climbing furniture; they are missing deadlines, losing the thread mid-conversation, and starting five things.

2. Developmental history. DSM-5-TR requires evidence that several symptoms were present before age 12. This is established through structured history — school patterns, report card themes, family recollection — not through childhood medical records, which almost nobody has. It's the criterion most commonly skipped, and skipping it is how adult ADHD gets both over- and under-diagnosed.

3. Impairment in two or more settings. Work and relationships, or work and home. Difficulty in one domain only points elsewhere.

4. Differential screening. This is the part that separates an evaluation from a confirmation. Conditions that produce ADHD-like presentations:

Mimic Why it matters
Obstructive sleep apnea, chronic insufficient sleepProduces inattention indistinguishable from ADHD
Thyroid dysfunctionSimple lab, frequently unchecked
Anxiety disordersConcentration failure from worry, not from attention regulation
DepressionExecutive dysfunction is a core depressive symptom
Trauma and PTSDHypervigilance mistaken for distractibility
Substance use, including cannabisBoth mimics and worsens ADHD
AutismSubstantial overlap, frequently co-occurring, often missed in adults
Bipolar disorderDistinguishing chronic impulsivity from episodic elevation changes treatment entirely

Any of these can produce a positive ADHD screen. Several commonly co-occur with ADHD, which is a different clinical situation than being the explanation for it.

5. Standardized instruments. ASRS-v1.1, CAARS, and similar scales are useful input. They are not the diagnosis. Any evaluation where the scale is the decision is not an evaluation.

6. Collateral. A partner, parent, or long-term friend adds information self-report can't. Optional, frequently valuable.


Why the 20-minute telehealth model fails

Adult ADHD is now a large commercial market, and a number of platforms have compressed evaluation into a brief video visit plus a rating scale.

This fails in both directions. It misses ADHD in people whose presentation doesn't fit the template — particularly women, and people whose comorbid depression is doing the talking. And it diagnoses ADHD in people whose actual problem is untreated sleep apnea, an anxiety disorder, or daily cannabis use, who then receive a stimulant that makes the underlying problem worse.

I've published in JAMA Psychiatry on oversight gaps in unregulated digital psychiatry platforms. This is the clinical version of that argument.


What happens here

Visit 1 (60–90 min) — full evaluation as described above.

Between visits — labs if indicated, collateral if you want it, sleep assessment if the history points there.

Visit 2 — diagnostic conclusion, whatever it turns out to be, and a treatment plan. If it isn't ADHD, I'll tell you what I think it is and what to do about it. That happens regularly and it is not a wasted evaluation.

Ongoing — titration, monitoring, and adjustment. See medication management.


If you're diagnosed

Medication is effective and worth taking seriously. My 2025 JAMA Psychiatry analysis found treatment associated with reductions in criminal convictions (32–41%), substance-related emergency visits (31–35%), and motor vehicle crashes (38–42%).

But medication is not the whole treatment. Emotional dysregulation, executive skill deficits, and years of accumulated self-narrative respond to therapy, not stimulants. I provide CBT and DBT-informed work directly.

Frequently Asked Questions

How do I get evaluated for ADHD as an adult in NYC?

Book a comprehensive psychiatric evaluation with a clinician who takes a developmental history and screens systematically for conditions that mimic ADHD. Expect 60 to 90 minutes, sometimes across two visits. A 20-minute video visit and a rating scale is not an evaluation.

Do I need childhood records to be diagnosed as an adult?

No. DSM-5-TR requires evidence of symptoms before age 12, but that evidence comes from structured developmental history — school patterns, recurring feedback themes, family recollection. Almost no adult has childhood medical records, and their absence is not a barrier.

What's the difference between an ADHD evaluation and neuropsychological testing?

ADHD is a clinical diagnosis made through interview and history. Neuropsychological testing is a separate, substantially more expensive battery indicated for specific questions like suspected learning disability or unexplained cognitive change. Most adults seeking ADHD diagnosis do not need it.

Can anxiety or depression look like ADHD?

Yes, and this is the most common source of misdiagnosis in both directions. Concentration failure from worry is not the same as attention dysregulation, and executive dysfunction is a core symptom of depression. They also frequently co-occur with ADHD, which is a different situation than being the explanation for it.

How many symptoms do adults need for an ADHD diagnosis?

Five or more in the inattentive or hyperactive-impulsive domain, versus six for children under 17. The threshold was lowered for adults in DSM-5 in recognition that presentation changes with age.

Will I be prescribed medication at the first appointment?

Not usually. I want the differential screening complete first. Prescribing a stimulant to someone whose actual problem is untreated sleep apnea or an anxiety disorder makes that problem worse.
