ADHD is a neurodevelopmental condition causing persistent inattention, impulsivity and sometimes hyperactivity that begins in childhood and often continues into adulthood. Diagnosis is clinical, based on a structured interview and rating scales. First-line treatment is stimulant medication (methylphenidate or amphetamine class), with non-stimulants such as atomoxetine, viloxazine and guanfacine as alternatives, plus skills-based therapy. Stedfast Psychiatry treats ADHD at 6300 North Wickham Road in Melbourne and by video across Florida; new patients call (561) 295-8859.

How we diagnose it
There is no single test for ADHD; the diagnosis is clinical. At Stedfast Psychiatry an ADHD evaluation includes a structured interview covering symptoms in childhood and today, functioning at work or school and at home, and a developmental, medical and family history. We use validated rating scales: the Adult ADHD Self-Report Scale (ASRS) and Conners or Vanderbilt scales for children and teens, with input from a parent, teacher or partner whenever possible. We screen for conditions that cause similar symptoms or coexist with ADHD, including anxiety, depression, bipolar disorder, sleep disorders, learning disabilities, substance use and thyroid disease. We ask about cardiovascular history, blood pressure and heart rate before prescribing stimulants, and request an EKG when there is a personal or family history of cardiac problems. For complex cases we can refer for formal neuropsychological testing.

Treatment for ADHD in Melbourne
Medication management
Stimulants are first-line for ADHD at every age and help 70 to 80 percent of people. The two families are methylphenidate (Ritalin, Concerta, Focalin) and amphetamine (Adderall, Vyvanse, Mydayis), each available in short and long-acting forms. We usually start with a long-acting formulation to cover the whole day and adjust the dose every one to two weeks until symptoms are controlled with acceptable side effects, typically within four to eight weeks. Non-stimulants are used when stimulants are not tolerated, when there is a history of substance misuse, when anxiety or tics are prominent, or by preference: atomoxetine (Strattera) and viloxazine (Qelbree) are norepinephrine reuptake inhibitors that take four to six weeks for full effect; guanfacine XR (Intuniv) and clonidine XR (Kapvay) are alpha-2 agonists that help impulsivity and hyperactivity and can be combined with a stimulant. Monitoring includes blood pressure, heart rate, weight, sleep and appetite at each visit, and growth tracking in children. Stimulants are controlled substances with specific prescribing rules, including for telehealth.
Psychotherapy and skills training
Medication improves attention, but it does not teach organization. CBT adapted for ADHD focuses on planning systems, time management, task initiation and managing the emotional fallout of years of missed deadlines. For children, parent behavior training and classroom accommodations (a 504 plan or IEP) are core treatments, and for young children under six behavior therapy comes before medication. ADHD coaching and executive-function skills training are useful adjuncts for adults and college students.
What to expect
The first visit is a 60-minute evaluation, in person or by video, that includes rating scales completed ahead of time. If ADHD is confirmed and medication is appropriate, a prescription is sent that day or after any needed cardiac screening. Follow-ups are every two to four weeks during dose titration, then every three months once stable, as required for controlled-substance prescribing. Telehealth follow-ups are available in Florida and South Carolina, within the current federal and state rules on prescribing stimulants by video.

Frequently asked questions
Who provides ADHD treatment at the Melbourne office?
The Melbourne team includes psychiatric nurse practitioners Alexandra Renninger, Hannah Sobas and Merlande Vance. Visits in Creole are available with Merlande Vance. Every provider works under psychiatrist oversight and the same evaluation standard: about an hour for a first visit, validated screening scales, and a written plan.
Can I be seen by video instead of coming to Melbourne?
Yes. Stedfast Psychiatry providers are licensed in Florida and offer video visits for evaluations and follow-ups. Some situations, including certain controlled-substance prescriptions and first visits for young children, require an in-person appointment at 6300 North Wickham Road.
Does the Melbourne office take my insurance?
We accept most major commercial plans and Medicare. Call (561) 295-8859 with your member ID and we will verify benefits before the visit. Self-pay new-patient evaluations are $185.
How soon can a new patient be seen in Melbourne?
Most new patients are scheduled within one to two weeks. If you need to be seen sooner, ask about a video visit; those often open up within days. If you are in crisis, call or text 988 or go to the nearest emergency room rather than waiting.
Can I get Deep TMS or Spravato as a Melbourne patient?
Yes. Stedfast Psychiatry is licensed for both. Your Melbourne provider does the evaluation and the prior authorization; treatment sessions are scheduled at our Palm Beach Gardens TMS center and the Palm Beach Gardens Spravato rooms.
How do I get tested for ADHD as an adult?
Schedule an ADHD evaluation with a psychiatric provider. You will complete the ASRS screening scale, then have a structured interview that covers your childhood, current symptoms and how they affect your life. Old report cards or input from a parent or partner help but are not required. Most adults receive a diagnosis and treatment plan at the first visit; formal neuropsychological testing is only needed when the picture is unclear or when learning disabilities are suspected.
What are the non-stimulant options for ADHD?
Atomoxetine (Strattera) and viloxazine (Qelbree) are once-daily norepinephrine reuptake inhibitors that are not controlled substances and take four to six weeks to reach full effect. Guanfacine XR and clonidine XR help impulsivity, hyperactivity and sleep, and are often combined with a stimulant in children. Bupropion is used off-label in adults who also have depression. Non-stimulants are somewhat less effective on average than stimulants but are the right choice for many people.
