Seizure / Fits / Blackout Evaluation

Understanding Seizures, Fits, and Blackouts

A seizure, fit, blackout, staring spell, sudden jerk, or unexplained loss of awareness should be evaluated carefully. Some events are epileptic seizures, while others may be fainting, low sugar, heart rhythm problems, panic episodes, sleep-related events, functional neurological episodes, or other medical problems.

Epileptic seizures are caused by abnormal electrical activity in the brain. But not every blackout or shaking episode is epilepsy. Correct classification matters because treatment differs.

At JHN, we evaluate seizure-like events through history, witness description, neurological examination, and EEG when appropriate.

Quick Check: What Kind of Episode Happened?

Patients or families may report:

• First-time seizure
• Recurrent fits
• Sudden loss of consciousness
• Staring spells
• Sudden confusion
• Jerking of arms or legs
• Body stiffening
• Tongue bite
• Injury during the event
• Urinary incontinence
• Confusion after the event
• Blackouts or fainting-like episodes
• Myoclonic jerks, meaning sudden brief jerks
• Episodes during sleep
• Events triggered by sleep deprivation, stress, alcohol, or missed medication

A phone video and a witness description can be extremely helpful.

Key Point

Not every blackout is a seizure. Blackouts can come from epilepsy, fainting, low sugar, BP drop, cardiac rhythm problems, panic episodes, sleep events, or functional neurological episodes.

Common Causes of Seizure-Like Events

Epilepsy

Epilepsy means a tendency to have recurrent unprovoked seizures.

First Unprovoked Seizure

A first seizure needs careful evaluation to estimate recurrence risk and identify possible causes.

Acute Symptomatic Seizure

This means a seizure triggered by a temporary medical problem such as fever, infection, low sugar, electrolyte disturbance, alcohol withdrawal, head injury, or medication/substance effects.

Syncope

Syncope means fainting, often due to a temporary drop in blood flow to the brain. It can sometimes include brief jerking and be mistaken for seizure.

PNES / Functional Episodes

PNES means psychogenic non-epileptic seizures. These are real episodes, but they are not caused by epileptic electrical discharges. They require careful, respectful diagnosis and treatment.

Sleep-Related Events

Some abnormal movements or behaviors occur during sleep and may mimic seizures.

What to Expect at Your First Visit

Your first visit focuses on reconstructing the event. We will ask what happened before, during, and after the episode; how long it lasted; whether there was confusion, tongue bite, injury, jerking, incontinence, triggers, or warning symptoms.

If a family member saw the event, their input is very important. If a phone video is available, please bring it.

Testing depends on the event pattern. EEG, ECG, labs, imaging, or referral may be advised depending on the case.

When to Seek Medical Evaluation

You should seek evaluation after:

• Any first seizure-like event
• Recurrent fits or blackouts
• Staring spells
• Unexplained lost time
• Jerks after waking up
• Events during sleep
• Injury, tongue bite, or incontinence during an event
• Events despite seizure medication
• Diagnostic uncertainty between seizure, syncope, and PNES/FND

FND means functional neurological disorder, where real neurological symptoms occur due to nervous-system functioning problems rather than obvious structural damage on routine tests.

When to Seek Urgent Care

Seek urgent emergency care if:

• A seizure lasts more than 5 minutes
• Repeated seizures occur without full recovery
• There is a pregnancy
• There is a head injury
• There is a fever or neck stiffness
• There is persistent weakness after the event
• There is a breathing difficulty
• There is severe confusion
• It is the first seizure in an elderly patient
• There is chest pain or fainting with injury
• There is concern for poisoning, overdose, or severe metabolic illness

How JHN Evaluates Seizure-Like Events

Evaluation may include:

• Detailed patient history
• Witness description
• Phone video review when available
• Event timing, triggers, duration, and recovery
• Injury, tongue bite, incontinence, and confusion review
• Sleep deprivation, alcohol, medication, fever, sugar, and metabolic review
• Neurological examination
• Differentiation between seizure, syncope, PNES/FND, sleep events, and metabolic causes
• EEG when clinically indicated
• ECG if fainting or cardiac cause is possible
• Lab testing when clinically appropriate
• MRI/CT referral when first seizure workup or red flags require imaging

Treatment Approach

Treatment depends on the diagnosis and risk:

• Education and safety counseling after a first event
• Anti-seizure medicine when clinically appropriate
• Trigger management, such as sleep deprivation or alcohol
• Review of existing seizure medicines and adherence
• EEG or video EEG if events are unclear
• Cardiac/syncope pathway if events are not epileptic
• Psychology/psychiatry support when PNES/FND is suspected
• Driving, swimming, heights, machinery, and safety counseling
• Follow-up to review recurrence risk and treatment response

Video EEG means EEG recorded with video, so physical events can be compared with brain-wave activity.

Patient-Friendly Summary

A seizure-like event deserves careful classification, not guesswork. The right diagnosis prevents both under-treatment and unnecessary treatment.
