Key points
- In the long-term MTA follow-up of 558 children, about 90% still had residual symptoms into young adulthood, and most moved between remission and recurrence over time.
- Adults are assessed against a threshold of five symptoms, compared with six for children.
- A new prescriber in New York makes an independent decision and must consult the Prescription Monitoring Program registry before prescribing a stimulant.
- Schedule II stimulant prescriptions cannot be refilled in New York; each fill needs a new prescription.
- The U.S. Department of Education says an IEP or Section 504 plan is generally not sufficient documentation for college accommodations.
Plenty of adults in New York were diagnosed with ADHD in elementary or middle school, took medication for some years, and then stopped: the pediatrician aged them out, college got in the way, insurance changed, or things seemed fine for a while. Coming back to care at 24 or 41 raises practical questions. This page sets out what to gather, what the new clinician will do, and how adult care differs from what you remember.
Why a new clinician will re-evaluate
A re-evaluation is standard practice, and it does not mean your childhood diagnosis is doubted. Three things have changed since it was made.
Symptoms move over time. The longest follow-up of treated children, the MTA study, tracked 558 participants to an average age of 25. About 30% had a full remission at some point, but 60% of those later had a recurrence. Only 9.1% showed sustained recovery by the end of the study, and about 90% still had residual symptoms as young adults. Most people fluctuated. An older single estimate, cited in American Family Physician, is that about 29% of childhood cases persist into adulthood. The numbers differ because the studies define persistence differently.
The threshold is different. Adults are assessed against five symptoms of inattention and/or hyperactivity-impulsivity, where children need six, and the question is how symptoms affect adult settings such as work, finances and relationships.
Other things may have developed. Anxiety, depression, sleep problems and substance use can appear in the years between, and each one changes what treatment is sensible.
The prescriber also carries the responsibility. In New York a practitioner prescribing a controlled substance decides independently whether it is appropriate and must consult the Prescription Monitoring Program registry no more than 24 hours beforehand. A years-old diagnosis from another office informs that decision without settling it.
Step 1: Collect what exists
You are in a better position than an adult with no history at all, because a childhood diagnosis is direct evidence that symptoms began before age 12. Look for:
- the original evaluation report, from a psychologist, psychiatrist, pediatrician or school;
- pediatric or family practice records showing the diagnosis and medications tried;
- an IEP, Section 504 plan or other school support plan;
- report cards with teacher comments;
- any later evaluations, for example from a college disability office;
- your own notes on which medications helped and which caused problems.
Ask your previous clinic, your parents and your school district. If records cannot be found, say so and move ahead. A missing file does not block an evaluation, as explained in getting evaluated for ADHD without childhood records.
Step 2: Choose a New York prescriber
Any New York-licensed physician with a DEA registration can evaluate you and prescribe, as can nurse practitioners. The clinician must hold a New York license, or be otherwise authorized to practice here, if you are in New York during the visit, which matters if your old prescriber was in another state.
When you call, a short script saves time:
Ask as well whether the same clinician prescribes if medication is recommended, and how many visits the evaluation usually takes.
Step 3: Prepare for the evaluation
CHADD describes a full adult evaluation as an interview from childhood to the present, input from a partner or parent, rating scales, screening for co-existing conditions and a medical check. An AAFP toolkit notes that adult diagnosis usually takes two to three visits. Bring:
- the records from Step 1;
- a list of every current medication and supplement;
- medical history, including heart conditions and blood pressure;
- the name of someone who knows you well and is willing to be contacted or complete a questionnaire;
- a few concrete examples of how symptoms affect work, home and money now;
- photo ID and insurance details.
Say plainly why you stopped treatment and why you are returning. Both are useful clinical information, and neither counts against you.
Step 4: Understand how adult prescriptions work here
If you last took a stimulant as a child, a parent probably handled the logistics. Adult care in New York has rules worth knowing before the first prescription.
| Rule | What it means for you |
|---|---|
| No refills on Schedule II medications | Each fill requires a new prescription from the prescriber |
| Supply limits | The base limit is a 30-day supply; a prescriber may write up to three months for attention deficit disorder, though insurers and pharmacies can be stricter |
| Registry check | The prescriber must consult the state Prescription Monitoring Program registry no more than 24 hours before prescribing a controlled substance |
| Telehealth | As of October 2026 a stimulant can be started after an audio-video visit, under federal flexibilities that run through December 31, 2026 |
The full set, with sources, is in New York's rules for ADHD stimulant prescriptions.
The medication itself may also change. Your clinician will choose based on your adult health, your schedule and your history, and may suggest a different product from the one you took at ten, or a non-stimulant, or a start without medication. Do not restart on leftover pills from years ago or on someone else's prescription. The FDA advises disposing of unused or expired stimulants promptly and never giving your medication to anyone else.
Step 5: Sort out paperwork for school or work
Old school plans do not carry over. The U.S. Department of Education's guidance for college students says an IEP or Section 504 plan "may help identify services that have been effective for you" but is "generally not sufficient documentation" at the postsecondary level. Colleges and exam boards set their own rules on how recent an evaluation must be.
If you expect to ask for accommodations, tell the clinician at the start so the adult evaluation report covers what the requester needs. The requirements are compared in what an ADHD evaluation report needs for work, school and exams.
What changes from pediatric care
- You are the historian. Nobody is collecting teacher forms for you; the clinician relies on your account and on people you nominate.
- Appointments are yours to keep. Because there are no refills, a missed follow-up can mean a gap in medication.
- Goals shift. Treatment is aimed at work, driving, finances, relationships and health, and may include skills-based therapy alongside medication.
- Costs are yours to check. Coverage for visits and medication depends on your own plan now.

Questions
Do I have to be re-diagnosed as an adult if I was diagnosed as a child?
Expect a re-evaluation. A new clinician will confirm the history, assess current symptoms and impairment against adult criteria, and check for other conditions before prescribing. Your childhood diagnosis and records make that process quicker and help establish that symptoms began early.
Can a new doctor simply restart the medication I took as a child?
The prescriber makes an independent decision and is not bound by an earlier prescription. Your health, other medications and current symptoms may point to a different product or approach. In New York the prescriber must also consult the state registry before prescribing a stimulant.
Can I have outgrown ADHD?
Some people do improve. In the MTA follow-up study about 30% of participants had a full remission at some point, although 60% of those later had a recurrence, and only 9.1% showed sustained recovery. Symptoms often change in form and fluctuate with circumstances, which is why an adult assessment is useful.
Will my old IEP or 504 plan get me accommodations in college?
Usually not without more. Federal guidance says an IEP or Section 504 plan is generally not sufficient documentation at the college level, though it can show which supports worked. Each college sets its own documentation rules, so check them before your evaluation.
My childhood prescriber was in another state. Can they treat me now that I live in New York?
Only if they hold a New York license or are otherwise authorized to practice here. The requirement follows where the patient is located during the visit. Most people in this position establish care with a New York-licensed prescriber.
