Seizure auras explained: Signs and more

Seizure Auras: Understanding the Warning Signs Before a Seizure Hits

Living with epilepsy often means navigating a world filled with unpredictability. But for many individuals, seizures don’t arrive out of the blue. Instead, they begin with subtle—or sometimes striking—early warning signals known as seizure auras. Recognizing these early indicators is not only empowering, but it can also make a huge difference in maintaining safety and managing one’s condition more effectively.

Seizure auras are not just hints of an impending seizure—they’re technically seizures in their own right. They represent the very first phase of focal seizures, starting in one specific part of the brain and sometimes spreading further. These auras might show up as a strange smell, a sudden wave of fear, a weird taste in your mouth, or visual distortions. They may seem confusing or surreal, but they can be the key to gaining control over your epilepsy.

This in-depth guide explores the types, causes, symptoms, and responses to seizure auras, shedding light on a frequently misunderstood aspect of epilepsy. Whether you live with epilepsy or care for someone who does, understanding auras can be a game-changer.

What Exactly Is a Seizure Aura?

Imagine standing on a beach as a distant storm rolls in—you feel the first wind gusts, a change in the air, maybe a faint rumble. That’s similar to what an aura feels like for someone with epilepsy. It’s the brain’s way of signaling that a seizure is brewing, even before any visible symptoms occur.

Seizure auras are actually focal aware seizures—meaning that a person remains conscious and aware while experiencing them. These episodes occur when abnormal electrical activity begins in a localized part of the brain. Depending on where that disruption happens, the aura will manifest with different sensations or emotions.

The term “aura” comes from the Greek word for “breeze,” which is fitting—many describe these experiences as subtle, passing sensations. Yet, for some, they can be intense and unmistakable. While not everyone with epilepsy experiences auras, research estimates that between 22% and 83% of people do—a wide range due to the variety of epilepsy types and reporting methods.

Importantly, an aura may be the entire seizure if the electrical activity doesn’t spread. But it can also serve as a crucial warning that a more intense, generalized seizure (like a tonic-clonic seizure) is imminent.

Different Types of Seizure Auras

Seizure auras can take many forms. They vary widely depending on the part of the brain involved, which is why they’re so unique and personal. Let’s look at the main categories:

1. Sensory Auras

These are disturbances in any of the five senses and are the most commonly reported.

• Visual: Seeing flashing lights, zigzag lines, shimmering colors, or objects appearing distorted.
• Auditory: Hearing phantom sounds like ringing, buzzing, or even voices no one else hears.
• Olfactory: Smelling things that aren’t there, such as burning rubber, smoke, or perfume.
• Gustatory: Tasting something metallic, bitter, or sour without eating anything.
• Tactile: Feeling sensations like tingling, pins and needles, or the illusion of something crawling on your skin.

2. Emotional Auras

These auras strike the emotional centers of the brain, particularly the amygdala or limbic system.

• Sudden Fear or Panic: Often described as intense dread that doesn’t match the current situation.
• Joy or Euphoria: Feeling suddenly happy, giddy, or spiritually “lifted.”
• Sadness or Anger: Unexpected mood changes, sometimes severe and unsettling.

These emotions are intense and often described as being unlike typical feelings—more raw, exaggerated, and unprovoked.

3. Cognitive Auras

These auras affect how you process thoughts and perceive reality.

• Déjà Vu: A powerful sense that you’ve experienced a moment before.
• Jamais Vu: Familiar places or people suddenly seem unfamiliar or strange.
• Time Distortion: Feeling like time is speeding up or slowing down.
• Racing Thoughts: Thoughts become rapid or overwhelming.

4. Physical Auras

Auras can also involve bodily sensations or internal experiences.

• Stomach Sensations: A fluttery feeling, often called an “epigastric rising” sensation.
• Dizziness or Lightheadedness: Feeling like you might faint or fall.
• Headaches or Pressure: Localized head pain or odd pressure in the skull.
• Muscle Twitches or Sensory Waves: A sense of energy or movement through the limbs or torso.

What Triggers a Seizure Aura?

Though the immediate cause of a seizure is abnormal brain activity, many factors can act as triggers, especially for those prone to auras. Recognizing and avoiding these triggers is a key part of seizure management.

Top Triggers Include:

• Stress: Chronic stress or sudden emotional trauma can lower your seizure threshold.
• Lack of Sleep: Even one night of poor sleep can raise the risk of a seizure.
• Hormonal Changes: Especially during menstruation, pregnancy, or menopause.
• Flashing Lights: A risk for those with photosensitive epilepsy.
• Alcohol or Drug Use: Especially withdrawal after heavy use.
• Low Blood Sugar: Skipping meals or poor nutrition can trigger episodes.
• Fever or Illness: Even mild infections can lead to increased seizure activity.
• Certain Medications: Especially those that lower the seizure threshold.

Understanding your personal triggers—and logging them—can make a huge difference in predicting and reducing seizure activity.

Diagnosing Seizure Auras: How Doctors Identify the Condition

Recognizing that you may be experiencing seizure auras is the first step. But a formal diagnosis is crucial for getting proper treatment and preventing more severe seizures. Because aura symptoms can resemble other conditions—like panic attacks, migraines, or dissociation—it’s vital to undergo a comprehensive medical evaluation.

The Diagnostic Process: What to Expect

Your doctor will begin by asking about your medical history, specifically focusing on:

• The nature of your aura symptoms
• When and how often they occur
• Whether they lead to larger seizures
• Any family history of epilepsy or neurological issues

This interview may feel deeply personal, but sharing honest details is essential. It helps your doctor pinpoint the type of epilepsy and tailor the treatment accordingly.

Neurological Exam and Observation

Most people with epilepsy will have a normal neurological exam between seizures. But your doctor will still assess reflexes, coordination, muscle tone, and sensory response to check for underlying neurological issues.

Sometimes, your doctor may ask you to keep a seizure diary—a record of your auras, their timing, triggers, and how they feel. This information can be invaluable in detecting patterns and guiding diagnosis.

EEG: The Gold Standard for Brain Activity Monitoring

An electroencephalogram (EEG) is one of the most important tools for diagnosing seizure activity. This test records your brain’s electrical activity via electrodes placed on your scalp. It’s painless and noninvasive but may not always catch seizure activity unless it’s happening during the test.

If your routine EEG comes back normal, your doctor might recommend:

• Extended EEG Monitoring: A longer test to capture rare or sporadic events
• Video-EEG Monitoring: Combines EEG data with video to correlate physical symptoms and brain activity

Imaging Tests to Look Inside the Brain

To explore possible structural causes of your seizures, your doctor might order:

• MRI (Magnetic Resonance Imaging): Offers high-resolution images of your brain to check for tumors, lesions, or abnormal development
• CT Scan: Often used in emergencies but provides less detail than an MRI
• PET or SPECT Scans: Used in complex cases to assess brain function or blood flow

Blood work and neuropsychological testing may also be used to rule out metabolic issues or assess memory, attention, and other cognitive functions that might be affected by seizures.

Treating Seizure Auras: Medication, Lifestyle, and Holistic Care

Seizure auras are manageable, and with the right approach, many people find relief from frequent episodes. The foundation of treatment involves antiepileptic medication, but lifestyle changes and holistic methods also play crucial roles.

1. Anti-Seizure Medications (ASMs)

Also called antiepileptic drugs (AEDs), these medications work by stabilizing electrical activity in the brain. Your neurologist will choose the most suitable option based on the type of seizure you have and your overall health.

Common medications for focal seizures and auras include:

• Carbamazepine: Often used as a first-line treatment for focal seizures
• Lamotrigine: Known for its mild side effect profile and effectiveness
• Levetiracetam: Widely used, though some experience mood-related side effects
• Oxcarbazepine: A newer version of carbamazepine with fewer drug interactions
• Valproate: More effective for mixed seizure types

Finding the right medication is a process—it may take time and require some trial and error. It’s critical to take your meds exactly as prescribed, as missed doses are a common cause of seizure recurrence.

2. Lifestyle Changes That Support Seizure Control

Lifestyle habits have a major impact on seizure control, and even small adjustments can make a big difference.

• Sleep: Aim for consistent, quality sleep every night. Avoid screen time before bed and maintain a calming bedtime routine.
• Nutrition: Eat balanced meals regularly. Avoid skipping meals, and watch blood sugar levels. Some people benefit from low-carb or ketogenic diets.
• Stress Management: Practice mindfulness, yoga, journaling, or deep breathing to help control emotional triggers.
• Avoid Triggers: Limit alcohol, caffeine, and screen exposure. Track triggers in a journal to pinpoint patterns.

3. Complementary and Alternative Therapies

While not a replacement for medical treatment, many people with epilepsy find relief from complementary therapies.

• Yoga & Meditation: Help reduce stress and potentially decrease seizure frequency.
• Biofeedback: Teaches control over physical responses like heart rate and may help with aura awareness.
• Acupuncture: While evidence is limited, some report fewer seizures with consistent acupuncture.
• Aromatherapy: Calming scents like lavender or peppermint may ease anxiety-driven auras, though caution is advised with strong smells.

Always discuss these therapies with your doctor to ensure they won’t interfere with your treatment plan.
