Serving Orlando, Osceola, Polk & Seminole counties
Your neurology testing, treatment and prescriptions in one place.
Nerve, muscle and brain testing on site. Infusion suites in the same building. An in-house pharmacy, and a dietitian who works from your lab results. Four Central Florida offices — so the whole workup takes weeks, not a year of driving between them.
Same-day appointments available now — first come, first served. Open Monday to Friday, 9 am to 5 pm, by appointment. Most major insurance and Medicare accepted.
At a glance
What this practice means for you.
Two things come before everything else here: how the visit feels, and whether the patient actually gets better. Every choice below follows from those.
You come first, and you stay in charge.
- Same-day appointments. One number for all four offices.
- Testing, treatment, pharmacy and nutrition in one place.
- We tell you what it will cost before we schedule it.
- You can have any service done elsewhere. It changes nothing about your care here.
Your patient comes back to you.
- We answer the question you asked — and return the patient.
- We do not take over the care you are already managing.
- Report in 3 business days, with the data behind it.
- Urgent findings are phoned to you the same day.
Nothing costly starts without the diagnosis behind it.
- Confirmed testing before any immunotherapy is proposed.
- Response re-measured — therapy that is not working is stopped.
- One lab and one record, so studies are not repeated.
- Office-based billing, without hospital facility fees.
Cost of care
The same medication. Often a much smaller bill.
Identical drug. Identical dose. What changes is where it is billed from.
A hospital outpatient department adds a facility fee on top of the drug and the nursing time. An independent office does not have one to add. For infusion therapy, where the drug itself is expensive, that difference is usually what a patient actually feels.
We verify your benefits and give you the number before anything is scheduled — not after the first statement arrives.
What we do before you commit
- Confirm your plan covers the study or therapy
- Submit prior authorization with the supporting data
- Quote your expected out-of-pocket share in writing
- Tell you if another site of care would cost you less
What you actually pay depends on your plan, your deductible and your coinsurance. We do not promise a specific saving — we tell you your number before you decide.
What we offer
Everything the workup needs, under one roof.
Most neurology patients get sent to a testing lab in one town, an infusion suite in another, and a pharmacy that has to order the medication. All of it happens here.
Neurodiagnostic testing
EMG and nerve conduction, EEG, autonomic reflex testing and QSART — performed and read by the neurologist, usually the same day as your visit.

Symptoms we hear every week.
If one of these sounds like you, it is worth a visit — most have a specific test that answers them.
The difference
Four reasons this is faster than the usual route.
- 01
Testing at the same visit
Nerve, muscle and brain studies are performed in our own lab — no separate appointment at a hospital across the county, no six-week wait for a slot.
- 02
The neurologist performs and reads your study
Not a technician running it and a stranger reading it three days later. That is why most patients get their results the same day.
- 03
Treatment starts here
If your diagnosis calls for infusion therapy, the suite is in this building and the team already has your chart. If it calls for a medication, the pharmacy is down the hall.
- 04
Four offices across Central Florida
Orlando, St. Cloud, Davenport and Sanford, with shared scheduling and one record — so you go wherever is closest to home or work.
Medical nutrition therapy
A dietitian on the team, not a shelf of supplements.
Some neurological problems are caused by something measurable in the blood. A few are caused by supplements the patient is already taking. Both are missed when nobody looks.
Our registered dietitian nutritionist works from your lab results and your diagnosis, alongside Dr. Riaz — not from a questionnaire, and not from a product catalogue. We take supplements away about as often as we add them.
Nutrition changes the outcome in
- —
B12, folate and copper deficiency — a neuropathy that looks like any other on testing, but is treated by replacement
- —
Too much vitamin B6 — high doses, common in over-the-counter nerve supplements, cause neuropathy
- —
Diabetes and prediabetes — glucose and weight control is the main lever on diabetic nerve damage
- —
Drug-resistant epilepsy — ketogenic and modified Atkins diets, which require dietitian supervision
- —
POTS and orthostatic intolerance — salt and fluid loading is first-line, non-drug management
Your neurologist
Dr. Shaheed Riaz
Board-certified neurologist with more than 20 years in practice, focused on neuromuscular disease, peripheral neuropathy, autonomic disorders and electrodiagnostic medicine.
Dr. Riaz performs and interprets the studies himself rather than sending them out to be read — which is why most patients hear their results the same day instead of waiting a week for a report.
What a first visit looks like
- 01
Your prior records and studies are reviewed before you arrive
- 02
History and a full neurological examination
- 03
Testing the same day where it is indicated and you are prepared for it
- 04
Results explained, a written plan, and a copy to your referring physician

Services
What we do
Diagnosis, treatment, nutrition and the prescription that follows — usually four separate businesses, here one practice with one record.
Testing
Neurodiagnostic testing on site
Four studies, performed in our own lab and interpreted by the neurologist who performed them — which is why results are usually discussed with you the same day.
Preparation matters more than most patients are told. Lotion on the skin, a missed medication instruction, or caffeine before autonomic testing can make a study unreadable. You get written instructions when you book.
EMG & nerve conduction (NCS)
Measures how well signals travel along nerves and how muscles respond. Answers numbness, tingling, weakness, cramps, carpal tunnel, pinched nerves in the neck or back, and neuropathy. About 45–60 minutes.
EEG, including sleep-deprived
Records the brain's electrical activity to evaluate seizures, blackouts, staring spells and unexplained confusion. Painless, about an hour. Wash your hair the morning of the test and skip conditioner and gel.
Autonomic reflex testing
Paced breathing, Valsalva and tilt-table with continuous heart rate and blood pressure. This is the study that turns “I get dizzy when I stand up” into a number — used for POTS, fainting and autonomic neuropathy. 60–90 minutes.
QSART (small fiber testing)
Measures sweat output driven by the smallest nerve fibers — the ones a standard EMG cannot see at all. Often the test that finally explains burning feet in someone whose EMG came back normal. About 45 minutes, no needles.
Treatment
Infusion suites
Private outpatient infusion chairs for patients whose neurological disease is immune-mediated — in the same building as the neurologist managing the case.
Used for CIDP, multifocal motor neuropathy, myasthenia gravis, autoimmune and paraproteinemic neuropathies, and some autoimmune encephalopathies. Each of those has diagnostic criteria, and we confirm them with testing before therapy is proposed — which is also what gets prior authorization approved and keeps it approved at renewal.
Your choice of provider is absolute. You may receive therapy here, at a hospital outpatient department, at another infusion center, or at home. We coordinate with whichever you choose and manage the neurological side either way.
What to expect
- 01
Benefits verified first. We tell you your expected out-of-pocket cost before anything is scheduled.
- 02
Loading, then maintenance. An initial course, then infusions at intervals set by how you respond.
- 03
Several hours per session. Recliner, wifi, and staff present throughout. Bring something to do.
- 04
Reactions are managed. Headache, chills and flushing are common early and handled by adjusting the rate, premedication and fluids.
- 05
Response is re-measured. Including repeat testing where appropriate. Therapy that is not working gets stopped, not continued indefinitely.
Pharmacy
In-house pharmacy & compounding
Neurological medications are unusually easy to lose on the way out of the office. Several are not stocked by retail pharmacies, most need careful titration, and a few work far better in a form no manufacturer makes.
You may fill any prescription written here at any pharmacy you choose, and your choice does not affect your care in any way.
Filled before you leave
Including the medications retail pharmacies routinely have to order — which is how patients end up starting treatment a week late.
Compounded formulations
Topical preparations for localized nerve pain, liquid forms for patients who cannot swallow tablets, dye- and preservative-free bases, and non-standard strengths for careful titration.
Refill follow-up
Neurological medications only work at a steady level. Refills are tracked and you are contacted before you run out.
Nutrition
Medical nutrition therapy
Nutrition earns a place in a neurology practice in a narrow set of conditions — and in those, it is not a supplement to treatment, it is the treatment. Outside them we say so.
Care is provided by a registered dietitian nutritionist, licensed in Florida, working from your laboratory results and your neurological diagnosis. Every plan is built with Dr. Riaz rather than beside him, and findings go back to your primary care physician.
What a first nutrition visit covers: a full review of what you actually eat, every supplement and dose you are taking, the medications that deplete specific nutrients, your relevant blood work, and whether any of it explains or worsens your symptoms.
Where the evidence supports it
- 01
B12, folate and copper deficiency. These cause a neuropathy indistinguishable from others on nerve testing. Blood work finds it and replacement treats it. Metformin, long-term acid-reducing medication, bariatric surgery and nitrous oxide all deplete B12.
- 02
Vitamin B6 excess. High-dose pyridoxine — routinely present in over-the-counter “nerve support” products — causes a sensory neuropathy. Stopping it is the treatment, and it is one of the most commonly missed causes we see.
- 03
Diabetic and prediabetic neuropathy. Glucose control, weight and metabolic management are the strongest available levers on progression, and the main approach to small-fiber symptoms.
- 04
Thiamine deficiency. After bariatric surgery, with heavy alcohol use, or with prolonged vomiting. Untreated it causes permanent neurological injury; caught early it is reversible.
- 05
Drug-resistant epilepsy. Ketogenic and modified Atkins diets have genuine evidence in seizures that have not responded to medication. They require laboratory monitoring and dietitian supervision — this is not a diet to attempt from the internet.
- 06
Celiac and gluten-related neurological disease. Ataxia and neuropathy that respond to a strict gluten-free diet once the diagnosis is confirmed.
- 07
POTS and orthostatic intolerance. Increased salt and fluid intake is first-line management, before medication.
- 08
Idiopathic intracranial hypertension. Weight reduction is a primary treatment for the condition, not a lifestyle suggestion attached to one.
- 09
Migraine. Magnesium and riboflavin have modest supporting evidence; meal timing, hydration and caffeine patterns often matter more than either.
What we do not do
We do not sell supplements. There is no product line attached to this service, which is what lets the dietitian tell you to stop taking something.
We do not claim diet cures dementia, MS or ALS. Nutrition supports general health in those conditions and can correct specific deficiencies; it does not alter the disease, and anyone telling you otherwise is selling something.
We do not start a therapeutic diet without labs and a reason. If your testing does not point to a nutritional contributor, we will tell you that rather than write a plan anyway.
Memory
Memory & cognitive care
The usual advice for early memory trouble is to watch it. That is the one approach guaranteed to miss the causes that can actually be corrected.
Cognitive change has many causes and a meaningful share of them are treatable: thyroid disease, B12 and other deficiencies, sleep apnea, medication effects, depression, metabolic disease, alcohol, and the after-effects of head injury. Finding which are in play is the first job.
Regain Memory 360 is the training program we use afterward — a structured cognitive assessment paired with exercises targeted at the domains where you scored lowest, done online at home between visits, with progress re-measured at follow-up. It is a program of assessment, training and medical follow-up. It is not a drug and not a cure for dementia.
Who it is for
- —
Names and words going missing more than they used to
- —
Brain fog, or conversations taking more effort than before
- —
Thinking that has not felt the same since a concussion or stroke
- —
A family member who noticed the change before you did
- —
A parent with dementia, and a wish for a baseline while everything is still clear
Individual results vary. No cognitive program can be promised to prevent or reverse dementia.
Second opinions
Second opinion visits
Worth having when the illness is not behaving the way the diagnosis says it should. It is not disloyalty to your physician — many of these visits are arranged by physicians themselves.
Common reasons: a neuropathy that keeps getting worse on treatment, weakness the EMG never confirmed, episodes called seizures or called anxiety without a study that settles it, and dizziness on standing that has never had autonomic testing.
Sometimes a second opinion confirms the first. That is a real result too — it ends the doubt and lets treatment go forward with confidence.

Neurology
Conditions we treat
Nerve & muscle
Peripheral neuropathy, diabetic and chemotherapy neuropathy, CIDP, carpal tunnel and ulnar entrapment, radiculopathy, myopathy, foot drop, nerve injury.
Autonomic
POTS, orthostatic intolerance, fainting and near-fainting, small fiber neuropathy, abnormal sweating, palpitations on standing.
Brain & episodes
Seizures and epilepsy, blackouts and spells, staring episodes, post-concussion symptoms, unexplained confusion, memory change.
Nerve-related pain
Neck, back and limb pain where the imaging and the symptoms do not match, persistent deficits after surgery, nerve pain after injury.
Cost & billing
The same medication, billed differently
Patients are often surprised that the identical drug, at the identical dose, produces a very different bill depending on where it was given.
A hospital outpatient department bills a facility fee on top of the drug and the nursing time, because it is part of a hospital. An independent office has no facility fee to add. For infusion therapy, where the medication itself is expensive, that is usually the difference a patient actually feels — and it is a difference in billing structure, not in the medicine.
The same logic applies to diagnostic testing. An EMG or EEG performed in a physician office is billed as a professional service. The same study in a hospital setting frequently carries a facility charge as well.
None of this is a promise of savings. What you pay depends on your plan, your deductible and your coinsurance. Some plans are structured so the difference is small. We will tell you your number, for your plan, before you decide anything.
Before anything is scheduled
- We verify your benefits with your plan directly
- We submit prior authorization with the supporting test data
- We quote your expected out-of-pocket share
- If another site of care would cost you less, we say so
Insurance we work with
Most major commercial plans and Medicare. Coverage for diagnostic studies and infusion therapy varies more than most patients expect, and prior authorization is common for both — which is why we check first rather than bill you afterwards.
Call (407) 352-0450 with your plan details and we will tell you what is covered before you come in.
Not sure which service you need?
Call and describe what is going on. We will tell you which visit or study fits, and whether your plan covers it.
Locations
Four offices across Central Florida
All four offices are open Monday to Friday, 9 am to 5 pm, by appointment. Scheduling and records are shared, so book wherever is closest to home or work — one number reaches every office.
Same-day appointments are available now, first come first served. Call early in the day for the best chance of a same-day slot.
Insurance
We participate with most major commercial plans and Medicare. Diagnostic studies and infusion therapy are often subject to prior authorization — call with your plan before scheduling and we will verify benefits and tell you your expected share first.
What to bring
Photo ID, insurance card, your referral if your plan requires one, a current medication list with doses, and any prior neurology records, study reports or imaging discs.
Arrival
Arrive 15 minutes early. Wear loose clothing that allows access to arms and legs for nerve testing. Bring a driver if you are having a sleep-deprived EEG.
For patients
Before your visit
Most of what goes wrong with a diagnostic appointment is logistical, not medical. This is the part we would otherwise tell you twice on the phone.
Preparation
Instructions differ by study — skin preparation, caffeine, medications to hold, hair washing, drivers. You get a written sheet when you book.
Insurance
Most major plans and Medicare. Call with your plan and we will verify benefits and prior authorization before you come in.
Records
Requests are made in writing. Call the office and we will send you the release form to sign.
Telehealth
Follow-ups and results reviews can be done by video. Testing and physical examinations must be in person.
Frequently asked
Do I need a referral?
Does an EMG hurt?
How soon do I get results?
My last EMG was normal but I still have symptoms.
Can I take my medications before testing?
Can I get my prescription filled there?
Which office should I go to?
For referring providers
Send the case, keep the patient
We take consultative and diagnostic referrals from primary care, rheumatology, orthopedics, physiatry, endocrinology, pain management and podiatry. Testing-only referrals are welcome and are the majority of what we do.
Three kinds of referral
Testing only — you keep management, we perform and interpret the study and send the report back.
Consultation — full evaluation with testing as indicated, then back to you with a plan.
Second opinion — a difficult or refractory case, including review of prior studies and outside records.
What comes back
The full study with raw data tables, the neurologist's interpretation, the clinical impression and the recommended next step — written to answer the question you asked. Returned within 3 business days of the study.
Urgent questions
Progressive weakness, suspected acute inflammatory neuropathy, or a new focal deficit — call the office directly and we will fit the study in rather than routing it through normal scheduling.
We do not manage what you are already managing, and we do not recruit your patients for primary or ongoing care. A testing-only referral comes back to you as testing only.
Staying in touch
You will always know where your patient is.
The usual complaint about specialty referral is silence. Here is who to contact, for what, and what comes back to you.
Reaching us
- Scheduling or referral status — call (407) 352-0450 and ask for the referral desk.
- An urgent clinical question — call the same line and ask for the neurologist. You get a call back the same day, not a message in a queue.
- Referrals and records — fax (863) 421-4715, or use the secure email below.
- Secure email — [email protected]
What comes back, and when
- Urgent or unexpected findings — phoned to you the same day the study is done.
- The full report — within 3 business days, with the raw data, the interpretation and the next step.
- A patient who does not show — your office is told, so a missed appointment does not become a lost patient.
- Any change to the plan — if we start, stop or alter a therapy, you get a note. You never hear it first from your patient.

Patient choice
Patients are free to obtain any testing, infusion therapy or pharmacy service from any provider they choose. Referring here obligates neither the patient nor your practice to use any service we offer.
About
Neurology built around the answer
Neurodiagnostic Center is an outpatient neurology practice serving Central Florida, with its own diagnostic lab, infusion suites, pharmacy, dietitian and memory program across four offices.
The neurologist
Your physician
Board-certified in neurology with more than 20 years in practice, with a clinical focus on neuromuscular disease, peripheral neuropathy, autonomic disorders and electrodiagnostic medicine.
Every study performed here is conducted and interpreted by the physician — not run by a technician and read remotely days later. In nerve and muscle testing that distinction changes the answer: the study is adjusted in real time based on what the examiner finds, and the decision about which muscle to sample next is made while the needle is in.
A first visit
- 01
Records reviewed before you arrive
Send prior studies ahead so the visit starts where the last workup stopped.
- 02
History and examination
Locating the problem clinically is what determines which study is worth running.
- 03
Testing, often the same day
When the study is available and you are prepared for it, it is done at the visit.
- 04
Results explained, plan written
You leave knowing what was found, what was ruled out, and what happens next. Your referring physician gets the same.
The care team
Who else you will see
Registered dietitian nutritionist
Licensed in Florida, working from your laboratory results and your neurological diagnosis. Involved wherever nutrition genuinely changes the outcome — deficiency neuropathies, diabetic nerve damage, ketogenic diets in drug-resistant epilepsy, salt and fluid management in POTS — and honest with you when it does not.
Neurodiagnostic technologists
Preparing and running studies alongside the neurologist, and the people who make sure you arrive with the right instructions — which is what determines whether a study can be interpreted at all.
Infusion and pharmacy staff
Nurses monitoring every infusion from start to finish, and pharmacy staff who track your refills and call before you run out rather than after.
How we practice
A test is only useful if it can change something.
Fewer, better studies
The right study chosen after a careful examination beats a panel ordered to cover every possibility. We tell patients when a test they were promised will not answer their question.
Normal is a finding
A normal EMG in a patient with burning feet is not a dead end — it is an argument for testing the small fibers instead. Most second opinions turn on that kind of reading.
Say what is still unknown
Some cases do not resolve on the first pass. Naming the uncertainty and setting a re-check interval is more honest, and more useful, than a diagnosis that does not fit.
Appointments
Book an appointment
The fastest route is a phone call — scheduling a study means checking your insurance and giving you the right preparation instructions, and that is a conversation. Or use the form to prepare your request and we will call you back.
