Brooklyn is New York City's most populous borough: about 2.62 million people in the NYC Health Department's 2024 estimates, more than Queens and well ahead of Manhattan. Adults across Brooklyn look for ADHD care for the usual reasons, work that keeps slipping, a degree that stalled, or a child's diagnosis that made a parent recognize the same pattern in themselves. This page covers what is specific to Brooklyn: the campuses whose disability offices students deal with, the rules that apply to a video visit taken from a Brooklyn apartment, filling a prescription in the borough, and local public resources. It does not describe an office in Brooklyn. Call the office to ask how and where visits are held.

A note of background: Dr. Shershow came to New York as Associate Dean of Downstate Medical School. More on his background is on the about page.

Who in Brooklyn looks for adult ADHD care

In the Health Department's 2024 estimates, 32.0% of Brooklyn residents were 25 to 44 years old, above the citywide 30.7%, and 47.7% of adults 25 and older held an associate's degree or higher. Common starting points for adults here:

  • Students at Brooklyn College, Pratt Institute, NYU Tandon School of Engineering and LIU Brooklyn, who often need an evaluation because a disability office asked for documentation.
  • Working adults who notice that organization and follow-through problems have followed them from school into every job.
  • Parents whose child was recently evaluated and who recognized their own history in the questions.
  • Adults diagnosed as children who stopped treatment years ago and want to know whether it still makes sense. See restarting care after a childhood diagnosis.

Brooklyn campus disability offices

Each campus decides accommodations under its own rules. An evaluation can describe what it found and how symptoms affect you, but only the school decides what it grants, and no evaluation guarantees a diagnosis or an accommodation.

CampusOfficeWhat its own page says
Brooklyn College (CUNY)Center for Student Disability ServicesDocumentation should come from a qualified professional with expertise in the disability, list the professional's name, title, credentials and state license or certification number, be signed and dated. Accommodations are requested again before every semester, through CUNY Accommodate.
Pratt InstituteLearning/Access Center (L/AC)Names ADHD among the conditions students can register for, for classroom, housing and other campus accommodations. Located on the first floor of the Student Wellness Center, 200 Willoughby Avenue.
NYU, including Tandon School of EngineeringMoses Center for Student AccessibilityDetermines and implements accommodations for NYU students, including academic, housing, testing and assistive technology accommodations. The office is at 726 Broadway, 3rd Floor, in Manhattan.
LIU BrooklynLearning Center, Disability Support ServicesBrooklyn campus office on the 4th floor of the Library Learning Center, weekdays 9 a.m. to 5 p.m., with late-night hours available.

If you are preparing documentation for school or a licensing exam, ADHD evaluations for accommodations in NYC explains what testing agencies and colleges usually ask for.

Which rules apply to a video visit taken from Brooklyn

The state you are in at the time of the visit decides the rules. New York's State Education Department says a practitioner must hold a New York license, or be otherwise authorized, when providing services to a patient located in New York. Dr. Shershow holds New York and New Jersey licenses, and for a video visit you must be physically in one of those states.

  • Telehealth and stimulants. As of October 2026, New York has no in-person requirement of its own for prescribing controlled medications by telehealth and follows federal rules. The federal telemedicine flexibilities run through December 31, 2026. What replaces them had not taken effect as of October 2026.
  • Prescription monitoring. Under Public Health Law section 3343-a, every practitioner must consult the state's prescription monitoring program registry before prescribing a Schedule II, III or IV controlled substance.
  • Out-of-state students living in Brooklyn. A home-state prescriber's license does not follow you to New York for a video visit taken here. See ADHD care for out-of-state students.

Filling an ADHD prescription in Brooklyn

Whatever pharmacy you use in the borough, New York's regulation 10 NYCRR 80.67 applies:

  1. Schedule II prescriptions are not refilled; each fill needs a new prescription.
  2. The standard limit is a 30-day supply. For attention deficit disorder (code B), a practitioner may prescribe up to a three-month supply when the condition or code is written on the prescription.
  3. Another prescription within 30 days generally waits until all but a seven-day supply of the last one is used.

Supply of some stimulants has been uneven. Before a prescription is sent, call the pharmacy and ask whether the exact medication and strength is in stock. The FDA's drug shortage database shows national status, and stimulant shortages in New York lists practical steps.

Brooklyn resources that are not the practice

  • NYC Health + Hospitals/Kings County, Comprehensive Psychiatric Emergency Program (CPEP). The hospital describes a stand-alone psychiatric emergency program with a 24/7 psychiatric emergency room, a six-bed extended observation unit and a mobile crisis team. The entrance is on Winthrop Street at New York Avenue. The page says mobile crisis referrals can be made by patients or family by contacting 988.
  • NYC 988. Free, confidential mental health support by phone, text or chat, 24 hours a day, in more than 200 languages.
  • ACCES-VR Brooklyn District Office. 55 Hanson Place, 2nd Floor, serving Kings County. New York's vocational rehabilitation program helps adults whose disability affects finding or keeping work. See ACCES-VR for adults with ADHD.
  • NAMI-NYC Helpline. Call, text, chat or email, Monday to Friday, 10 AM to 5 PM, for help finding services and support groups.

For anyone in immediate danger, call 911.

Insurance questions under New York law

For plans regulated by New York, a state fact sheet says a first appointment with a mental health professional must be available within 10 business days. If your plan's network cannot meet that, file an access complaint with the insurer, which then has three business days to find a provider in its network. If it cannot, it must approve an out-of-network referral at the same copayment, coinsurance and deductible you would pay inside the network. New York's Behavioral Health Ombudsman (CHAMP) can help at 888-614-5400.

For this practice, call the office for current fees and to ask how insurance works with the practice, or start with the fees and insurance page.

How to start from Brooklyn

Call the office or use the call-back form on this page. Mention where you will usually be during visits, at home in Brooklyn, at work in Manhattan, or somewhere in New Jersey, because that decides which state's rules apply. Before the first visit, gather what you can about your childhood and school history, your current medications and any past treatment. The evaluation looks at current symptoms, history, health, and other explanations such as anxiety, depression or sleep problems, and ends with what it found and the treatment options that fit.

How care with Dr. Shershow works

  1. Call or request a call back

    The office talks with you about scheduling and answers questions about fees, insurance and how visits are arranged.

  2. Psychiatric evaluation

    Your current symptoms, your history since childhood, your health, and whether anything else explains what you are experiencing.

  3. Diagnosis and a plan

    What the evaluation found and the treatment options that fit you, including medication when it is appropriate.

  4. Regular follow-up

    Visits to check how treatment is working and adjust it. Follow-up visits are held by secure video. For a video visit you need to be located in New York or New Jersey.

Questions

Does Dr. Shershow have an office in Brooklyn?

This page does not describe an office in Brooklyn. Call the office to ask where and how visits are held. Follow-up visits are by secure video, and for any video visit you must be physically in New York or New Jersey.

Can I get an ADHD evaluation online from Brooklyn?

A video visit taken from Brooklyn falls under New York's rules, and Dr. Shershow holds a New York license. Whether the first visit is in person or by video is a question for the office. As of October 2026, New York follows federal telemedicine rules for stimulant prescribing, which run through December 31, 2026.

I study at Brooklyn College or Pratt. What documentation will the disability office want?

Each office sets its own rules. Brooklyn College's Center for Student Disability Services asks for documentation from a qualified professional that lists credentials and a state license number and is signed and dated, and Pratt's Learning/Access Center names ADHD among the conditions it accommodates. Check the office's page before your evaluation, and know that no evaluation guarantees an accommodation.

Do I need a referral?

Some insurance plans require a referral before a specialist visit, so check with your plan. Call the office to ask whether the practice needs one and how insurance works with the practice.

Is ADHD testing the same as a psychiatric evaluation?

What people call ADHD testing is usually a diagnostic evaluation built on a clinical interview, history and rating scales. Neuropsychological testing is a separate battery done by psychologists, and Dr. Shershow's practice does not provide it. The practice provides the psychiatric evaluation.

Where can I get help in a mental health crisis in Brooklyn?

Call 911 if anyone is in immediate danger. NYC Health + Hospitals/Kings County runs a 24/7 psychiatric emergency room, and NYC 988 offers free, confidential support by phone, text or chat at any hour.
