Quick Answer
An epilepsy specialist establishes whether an episode was a seizure, whether a seizure means epilepsy, and what follows for treatment, driving and safety. CNS evaluates adult seizure disorders across Las Vegas and Henderson, with routine and ambulatory EEG performed in-office and interpreted by a fellowship-trained epileptologist.
Key Takeaways
- Not every episode is a seizure. Faints, cardiac events, sleep phenomena and non-epileptic attacks all produce episodes that resemble one, and telling them apart is the substance of the consultation rather than a preliminary to it.
- Not every seizure is epilepsy. A single provoked seizure with an identified cause is a different situation from recurrent unprovoked seizures, and the distinction determines whether long-term treatment is appropriate.
- A normal EEG does not exclude epilepsy. It means nothing was captured during that recording, which is why an ambulatory study extending over days exists and why the description of the event still carries the most diagnostic weight.
- The eyewitness account is often the most valuable evidence available. What someone else saw during the episode frequently settles a question that no test can, which is why bringing that person or their written account changes the appointment.
- Driving and safety are part of the medical conversation rather than an afterthought. Nevada has its own reporting and licensing framework, and having that discussion early is better than discovering the rules after an incident.
01 — OverviewThe first question: was it actually a seizure
Episodes bring patients to neurology more often than diagnoses do, and the first job is establishing what happened rather than treating what it was assumed to be. A great deal of what arrives labelled as a seizure turns out to be something else, and a proportion of what arrives labelled as fainting turns out to be a seizure. This page sits within the wider neurological conditions library at Clinical Neurology Specialists.
What else produces an episode
Syncope, meaning a faint from a temporary drop in blood flow to the brain, is the commonest alternative and frequently includes brief jerking that observers reasonably describe as a convulsion. Cardiac arrhythmias produce collapse that can look identical and carry entirely different urgency. Sleep phenomena including parasomnias produce night-time events mistaken for nocturnal seizures. Non-epileptic attacks are episodes that resemble seizures but do not arise from abnormal electrical activity, and they are a real condition requiring real treatment rather than a diagnosis of exclusion applied dismissively.
Why the description outweighs the test
Diagnosis here rests on the account more than on any investigation, which is unusual in modern medicine and consistently surprises patients. What happened immediately before, whether there was a warning, what the person looked like during the event, whether there was tongue biting or incontinence, how long it lasted, and crucially how the person was in the minutes afterwards, all carry more diagnostic weight than a routine EEG. Confusion lasting minutes after an event points strongly one way; immediate clear-headedness points another.
Bringing the eyewitness, or the account
Most people cannot describe their own event, because the part that matters most is the part they were not present for. Whoever saw it holds the most valuable evidence available, and bringing that person to the appointment is worth more than any preparation a patient can do alone. Where that is impractical, a written account recorded soon after the event is the next best thing, and a phone video, if one exists, is better than either. That last point is worth saying plainly: recording an episode is not ghoulish, it is diagnostically useful.
Epilepsy is a tendency toward recurrent unprovoked seizures, which distinguishes it from a single seizure or from a seizure provoked by an identifiable and correctable cause such as low blood sugar, alcohol withdrawal or acute illness.
02The second question: does a seizure mean epilepsy
A seizure is an event. Epilepsy is a tendency toward recurrent unprovoked seizures. Those are different statements, and treating the first as though it automatically implies the second commits some patients to years of unnecessary medication while leaving others under-treated.
Provoked versus unprovoked
A provoked seizure has an identifiable and often correctable cause: low blood sugar, alcohol withdrawal, acute illness with high fever, severe electrolyte disturbance, certain medications, or acute head injury. Address the cause and the tendency may not persist. An unprovoked seizure occurs without such a trigger, and recurrence risk is what drives the decision about long-term treatment.
How the treatment decision is actually made
After a first unprovoked seizure the question is recurrence risk, which is assessed from the examination, the EEG, imaging and whether there is a structural or genetic explanation. Where risk is high, treatment usually starts after the first event. Where it is low and the event was isolated, watchful management with clear safety advice is a legitimate choice, and framing that as doing nothing misrepresents it. The American Epilepsy Society publishes the professional guidance clinicians work from here.
Why classification matters beyond the label
Seizures are classified by where they begin and how awareness is affected, and the classification is not academic: it guides which medications are appropriate, since some are effective for one seizure type and can worsen another. That is why an accurate description of the event feeds directly into a prescribing decision, and why a generic diagnosis of seizures leads to generic treatment that sometimes makes the situation worse rather than better.
| Feature | More typical of a seizure | More typical of a faint |
|---|---|---|
| Warning | An unusual smell, taste, feeling or dj-vu | Light-headedness, sweating, tunnel vision |
| Position | Can occur lying down or asleep | Usually standing or getting up |
| Duration | Often a minute or more | Usually seconds |
| Afterwards | Confusion lasting minutes | Rapid return to clear-headedness |
| Tongue biting | Side of the tongue, when present | Uncommon |
Had an episode nobody has explained?
Bring whoever saw it, or their written account. That is the single most useful thing you can do.
03What EEG can and cannot answer
Electroencephalography records the brain's electrical activity through sensors placed on the scalp. It delivers nothing to you; the sensors only listen. It is the most useful test in this area and the most widely over-interpreted, in both directions.
What it establishes
Whether abnormal electrical activity is present between events, which contributes to recurrence risk and to classification, and occasionally captures an event itself.
What it does not settle
A normal study does not exclude epilepsy. It means nothing abnormal appeared during that recording, which for a condition that is intermittent by nature is a limited statement.
When days are needed
Where events are infrequent and a short recording is unlikely to catch one, ambulatory monitoring records continuously over days at home rather than in a single appointment.
Routine and ambulatory, both performed in-office
CNS performs both formats in its own offices, described on the EEG guide and the ambulatory EEG guide. A routine study takes under an hour. Ambulatory monitoring is set up in the office and continues at home, which means the patient goes about ordinary life while recording, and that is the entire point: an event that never happens in a clinic may happen readily on a Tuesday evening.
Who reads it, and why that matters
Studies are interpreted by Dr. Anup Panduranga, who is fellowship-trained in epilepsy and reads the practice's EEGs. That matters because EEG interpretation is a genuinely specialised skill in which normal variants are commonly misread as abnormal, and an over-called EEG can commit a patient to years of unnecessary treatment. A study read by the physician who also manages epilepsy in the same practice keeps interpretation and clinical judgement in one place.
What imaging adds, and where it happens
Magnetic resonance imaging looks for a structural explanation and is usually appropriate after a first unprovoked seizure. CNS does not operate an imaging suite, so this is coordinated with an outside facility. Mentioning it at booking lets the sequence be planned in one pass rather than three, which matters when a driving decision is waiting on the results.
04Treatment, and what living with epilepsy involves
Most adult epilepsy is managed with medication, and the aim is the fewest seizures with the fewest side effects rather than a theoretical ideal. The first medication chosen is a reasoned decision rather than a certainty, and adjustment is the normal course rather than evidence of failure.
Why the first drug is a starting point
Selection depends on seizure type, other medical conditions, other medications, whether pregnancy is a consideration, and how a given drug is tolerated by that individual. A substantial proportion of patients achieve control on the first or second medication tried. Where two appropriate medications at adequate doses have not achieved control, the situation is characterised differently and warrants reassessment rather than a third and fourth attempt on the same reasoning.
Neurostimulation device follow-up
Where medication has not achieved control, some patients have a vagus nerve stimulator or deep brain stimulation device implanted by a surgical centre. CNS manages and follows up those devices, including programming adjustments, in coordination with the centre that implanted them. Detail is on the vagus nerve stimulation guide. The practice does not perform the implantation itself, which is neurosurgical, and says so rather than implying otherwise.
Sleep, alcohol and the practical variables
Sleep deprivation is among the most reliable seizure provocations and among the most modifiable. Alcohol matters, particularly the withdrawal phase after heavy use rather than the drinking itself. Missed medication doses are a leading cause of breakthrough seizures, which makes routine and reminders a clinical intervention rather than lifestyle advice. Illness with fever, dehydration and some over-the-counter medications also matter, and asking about all of these is part of a follow-up appointment.
Women, pregnancy and planning ahead
Medication choice interacts with pregnancy planning in ways that need discussing well before a pregnancy rather than during one, because some options carry considerations that make an earlier switch preferable to a later one. Raising it early, even where pregnancy is hypothetical, is the useful approach, and it is a conversation the practice will start rather than wait to be asked about.
05Driving, safety and the conversations that follow a diagnosis
The questions patients most want answered after a seizure are rarely clinical. They are about driving, work, and whether it will happen again in public.
Driving in Nevada
Nevada operates its own framework for licensing after a seizure, including requirements around seizure-free intervals and medical reporting. Because those requirements change and are applied case by case, this page states that the framework exists rather than quoting a rule that might be out of date, and the specifics are addressed in your consultation against your actual circumstances. What is worth knowing in advance is that the conversation happens, that it is a medical and legal matter rather than a discretionary one, and that having it in a consulting room is considerably better than after an incident.
Everyday safety without over-restricting
Practical measures reduce risk without shrinking a life to nothing: showers rather than baths, caution around swimming alone, care with heights and with cooking, and telling the people you spend time with what to do. That last item is the highest-value one, and the Epilepsy Foundation publishes accessible first-aid guidance worth sharing with family and colleagues. Over-restriction carries its own cost, and a plan that isolates someone is rarely the right one.
What to tell an employer, and what you need not
This depends on the role and on what safety-critical duties it involves, and it is worth working through rather than deciding in the first week after a diagnosis. Many people continue in their existing job with no change. Where a role involves driving, heights or machinery the conversation is different, and having a clear medical account of your situation makes it a manageable discussion rather than an alarming one.
When an event is an emergency
A seizure lasting more than five minutes, seizures occurring one after another without recovery in between, a first seizure in someone with no history, a seizure with injury, or a seizure in pregnancy all warrant emergency care rather than an appointment. That is the one part of this page that is not a matter of judgement, and it is worth family knowing it too.
06Epilepsy care across the valley
Both CNS offices provide epilepsy evaluation and both perform routine and ambulatory EEG, so the choice between them is about travel. Clark County has a thin supply of neurologists relative to its population, and subspecialty epilepsy availability is thinner still, which is worth factoring in when an appointment is being arranged after a first event.
Epilepsy Las Vegas and the west valley
Patients seeking epilepsy Las Vegas care generally attend the West Flamingo Road office, which the 215 and Summerlin Parkway feed toward. Consultations, EEG set-up and device follow-up are handled there.
Epilepsy Henderson NV and Green Valley
For epilepsy Henderson NV patients the West Horizon Ridge Parkway office sits just off the 215 Beltway. Epilepsy Green Valley Henderson residents almost always find that address the shorter trip, and it carries the same accredited laboratory.
Epilepsy Summerlin and the northwest
Epilepsy Summerlin patients are usually closest to West Flamingo Road. CNS consolidated from a wider footprint into two offices, so those further north attend whichever is the shorter drive; we will not imply a third location exists.
Epilepsy Southern Nevada: why continuity matters here specifically
Epilepsy Southern Nevada care is long-term by nature, and the record is the treatment as much as the prescription is. Seizure frequency over years, which medications were tried and at what doses, what side effects occurred, how an EEG read eighteen months ago compared with today, and whether a device setting was adjusted are all only interpretable against a continuous record. A patient who changes practices repeatedly loses that baseline, and rebuilding it takes longer than keeping it. That is the argument for choosing a practice you can stay with, and coverage and any prior authorisation are verified before your visit, with detail on the insurance page.

Five board-certified physicians
Leo Germin, M.D., FAANEM, founder and medical director, triple board-certified in Neurology and Vascular Neurology through the ABPN and Neuromuscular Medicine through the ABEM, with subspecialty certification in Neurosonology and Neuroimaging. Anup Panduranga, M.D., fellowship-trained in epilepsy. Eric Gutglueck, M.D., neuromuscular medicine and neuromuscular ultrasound. Jessica A. Knirk, M.D., general adult neurology with Botox for chronic migraine. William Lujan, M.D., broad general adult neurology.
Four advanced practice providers
Fara Tan, APRN, MSCN, a Multiple Sclerosis Certified Nurse through the Multiple Sclerosis Nurses International Certification Board. Lindsey Evans, PA-C, general neurology and electromyography. Terra Fonseca, PA-C, a surgical and vascular background applied to general adult neurology. Alissa Nakamura, PA-C, board-certified through the NCCPA, with three years in pain management that transfer directly to nerve-injury and neuropathy questions.
Spread, not headcount
A referral that lands somewhere without neuromuscular or epilepsy depth often becomes a second referral, and each handoff adds weeks. Here an ambiguous nerve study can be reviewed by a neuromuscular specialist and an ambiguous EEG by a fellowship-trained epileptologist without the patient leaving the practice. Full biographies are on the providers page.
The Bottom Line
Two questions come before treatment: was the episode a seizure, and does a seizure mean epilepsy. Getting both right is what separates appropriate long-term treatment from years of medication nobody needed.
Frequently Asked Questions
How do I know whether my episode was a seizure?
Largely from the description rather than from a test. What preceded it, whether there was a warning, how long it lasted, and above all how you were in the minutes afterwards carry more diagnostic weight than a routine EEG. Confusion lasting minutes points one way; immediate clear-headedness points another.
Does one seizure mean I have epilepsy?
No. Epilepsy is a tendency toward recurrent unprovoked seizures. A single seizure with an identifiable and correctable cause, such as alcohol withdrawal or severe electrolyte disturbance, is a different situation, and whether long-term treatment is appropriate depends on recurrence risk.
My EEG was normal. Does that rule out epilepsy?
No. It means nothing abnormal appeared during that recording, which for an intermittent condition is a limited statement. That is why ambulatory monitoring over days exists, and why the account of the event remains the most important evidence.
What is ambulatory EEG and when is it used?
A continuous recording over days, set up in the office and continued at home while you go about ordinary life. It is used when events are infrequent enough that a one-hour study is unlikely to capture one. CNS performs both formats in its own offices.
Who interprets the EEG at CNS?
Dr. Anup Panduranga, who is fellowship-trained in epilepsy, reads the practice EEGs. That matters because normal variants are commonly misread as abnormal, and an over-called EEG can commit a patient to years of treatment they did not need.
Can I drive after a seizure?
Nevada operates its own licensing and reporting framework, including seizure-free interval requirements, and it is applied case by case. Your consultation addresses it against your actual circumstances. It is a medical and legal matter rather than a discretionary one.
Does CNS implant vagus nerve stimulators?
No. Implantation is neurosurgical and performed by a surgical centre. CNS manages and follows up those devices afterwards, including programming adjustments, in coordination with the centre that implanted them.
When is a seizure an emergency?
A seizure lasting more than five minutes, seizures occurring one after another without recovery in between, a first seizure in someone with no history, a seizure with injury, or a seizure in pregnancy all warrant emergency care rather than an appointment.
