Who can diagnose ADHD in New Brunswick?

New Brunswick licenses four kinds of clinicians to make the diagnosis

A family physician, a psychiatrist, a nurse practitioner and a licensed psychologist each hold the legal authority to diagnose adult ADHD in New Brunswick, and no one route produces a more official finding than another. The split that matters is prescribing: physicians and nurse practitioners can start and adjust medication, while a psychologist diagnoses and treats with psychological methods only. Each profession answers to its own regulator, and each keeps a public directory you can check before booking.

CNNB, once the Nurses Association of New Brunswick, licenses the nurse practitioner route

A nurse practitioner in this province can assess, diagnose, treat and prescribe for ADHD without a physician's sign-off. The regulator is the College of Nursing of New Brunswick, still reachable at the web address it used under its former name, the Nurses Association of New Brunswick, under the authority of the province's Nurses Act. CNNB's standards of practice for nurse practitioners set out the scope of prescribing, including federally controlled medications, the class that first-line ADHD stimulant treatments fall into; any coursework or condition attached to that authority is worth confirming directly with CNNB, since standards get revised.

The College of Psychologists of New Brunswick licenses the diagnosis, not the prescription

A psychologist licensed by the College of Psychologists of New Brunswick can diagnose ADHD, and the College's public search shows whether a given practitioner holds full licensure or is still completing supervised hours as a candidate. Testing-heavy cases, a psychoeducational workup for university accommodations, or a question about a learning disability sitting alongside ADHD, are where this route earns its cost, since it is billed privately and New Brunswick Medicare does not touch psychologist fees. Because the licence stops short of prescribing, a person who wants medication after this kind of diagnosis brings the report to a family doctor or nurse practitioner, who reviews it independently before writing anything.

A family doctor can close the loop alone, or send you to a psychiatrist

Plenty of New Brunswick family doctors, licensed through the College of Physicians and Surgeons of New Brunswick, diagnose an uncomplicated adult case without involving a specialist, and Medicare covers the visit. A referral to psychiatry tends to happen when another mental health condition is in the picture, when a prior treatment attempt did not work, or simply because the physician prefers not to manage stimulant prescribing themselves.

• Horizon Health Network and Vitalite Health Network run community mental health intake across the province's health zones; ask directly whether adult ADHD assessment is in scope where you live.
• If you have no family doctor, New Brunswick's patient registry for unattached patients is the formal route to one, and a nurse practitioner or virtual clinic can fill the gap meanwhile.
• Vitalite operates primarily in French and Horizon primarily in English, so if a French-language assessment matters to you, say so when you call intake or book privately.

One clinician's finding becomes another's starting point, within limits

Any of the four routes produces a diagnosis a New Brunswick prescriber will work from rather than repeat from scratch, though a prescriber still reviews your history independently before writing a prescription, since the decision to prescribe is theirs alone. A university, employer or insurer sets its own documentation rules on top of that, and some ask for a specific form or a report from a specific profession rather than accepting a short letter.

• A physician's or psychiatrist's diagnosis: usually accepted directly by another prescriber, and by most accommodation offices without extra testing.
• A nurse practitioner's diagnosis: carries equal prescribing weight; confirm with the specific institution for accommodations.
• A psychologist's diagnosis: needs a prescriber's own review before medication starts, but is often the preferred document when standardized testing is the point.

How much any of this costs, and what New Brunswick Medicare will and will not pay toward it, is answered in full on whether an ADHD assessment is covered by Medicare in New Brunswick rather than repeated here.

A video assessment with a licensed nurse practitioner is one legitimate route among the four

Finding Focus, a virtual clinic licensed to operate in New Brunswick, is staffed by nurse practitioners following DSM-5-TR criteria and CADDRA-aligned practice, and results plus a treatment plan are often ready within hours of the video visit. Adults 18 and over can book directly with no referral, and the assessment can just as easily conclude that ADHD is not present, since ruling it out is part of the job.
