You're stuck in traffic, your phone is blowing up with work emails, and you haven't slept more than five hours a night all week. Your chest feels tight. Suddenly, things go blurry. For millions of people living with epilepsy—or those who have never had a fit in their lives—the big question isn't just about genetics or brain injuries. It’s about the pressure cooker of modern life. Can stress induce seizures?
Yeah. It actually can.
But it’s not always as straightforward as "stress equals seizure." The relationship is messy. It’s physiological, psychological, and honestly, a bit of a biological feedback loop that doctors are still trying to map out fully. When we talk about stress-induced events, we’re often looking at two very different things: epileptic seizures triggered by high cortisol, and something called Psychogenic Non-Epileptic Seizures (PNES). Both look terrifying. Both are real. But they come from different corners of your nervous system.
The Cortisol Connection: How the Brain Hits a Breaking Point
Let's get into the weeds of the brain. You've got these things called neurotransmitters. Some are "excitatory" (they get things moving) and some are "inhibitory" (they calm things down). In a healthy brain, they’re in a delicate dance. Stress, especially the chronic, soul-crushing kind, dumps a bucket of cortisol and adrenaline into your system.
Cortisol is weird. In small doses, it helps you survive. In high doses? It actually changes the excitability of your neurons. For someone with a known seizure disorder, this spike in stress hormones can lower the "seizure threshold." Think of it like a dam. Everyone has a dam that keeps the electrical storms in their brain at bay. Stress acts like a heavy rainstorm that raises the water level. Eventually, the water spills over.
Research published in Epilepsy & Behavior has consistently shown that stress is the most frequently self-reported trigger for seizures. We aren't just talking about a bad day at the office. We’re talking about the cumulative load of grief, sleep deprivation, and anxiety. Dr. Sheryl Haut, a leading neurologist at Montefiore Health System, has spent years studying this. Her work suggests that if we can manage the stress, we can literally reduce the number of pills some patients have to take. It’s that powerful.
It’s Not All Epilepsy: Understanding PNES
Here’s where it gets complicated. Sometimes, stress doesn't just trigger an underlying electrical issue; it creates a physical manifestation of emotional trauma. This is what medical professionals call Psychogenic Non-Epileptic Seizures (PNES).
People used to call these "pseudoseizures." Honestly, that’s a terrible name. It sounds like the person is faking it. They aren't. PNES events are involuntary. They are a profound physical reaction to psychological distress. If you’ve ever seen someone faint from seeing blood, you know the brain can shut the body down when it can’t process a stimulus. PNES is like that, but on a much more intense scale.

The big difference? If you hooked someone having a PNES event up to an EEG (an electroencephalogram), you wouldn't see the classic "electrical storm" spikes associated with epilepsy. Instead, the brain waves look relatively normal, even while the body is shaking or losing consciousness. It’s the brain’s way of "short-circuiting" because it has no other way to deal with the internal pressure.
Why Sleep is the Great Multiplier
You can't talk about stress without talking about sleep. They are twins. Usually, when you're stressed, you don't sleep. When you don't sleep, your brain becomes incredibly "irritable" in a clinical sense.
Sleep deprivation is perhaps the most potent way stress induces seizures. During deep sleep, your brain does a sort of "reset" of its electrical activity. When you rob yourself of that, the neurons become hypersensitive. I've seen cases where a college student, totally healthy, pulls two back-to-back all-nighters fueled by caffeine and stress, only to have their first-ever grand mal seizure.
Is it epilepsy? Maybe not. It might just be a brain pushed past its mechanical limits.
Common Signs Your Stress is Hitting the Danger Zone
It's rarely a bolt from the blue. Usually, there are breadcrumbs. People often describe a feeling of "aura" or a specific type of rising anxiety before an event happens.
- The "Rising" Sensation: A weird feeling in the pit of your stomach that moves up toward your chest.
- Aphasia: Suddenly struggling to find very simple words during a stressful conversation.
- Sensory Distortions: Smelling something burnt or metallic that isn't there.
- Hyperventilation: This is a big one. Rapid breathing changes the pH of your blood, which can directly trigger seizure activity in susceptible people.
Real World Impact: More Than Just a Medical Fact
Think about the veteran coming home with PTSD. Or the mother working three jobs to keep the lights on. For these individuals, the "can stress induce seizures" question isn't academic. It's a daily threat.
In a 2017 study by the American Epilepsy Society, researchers found that mindfulness-based stress reduction (MBSR) actually changed the brain chemistry of participants. By practicing specific breathing and grounding techniques, patients were able to widen the gap between a stressful thought and a physical seizure response.

It’s not some "woo-woo" magic. It’s biology. By slowing the heart rate and lowering blood pressure, you're essentially telling your brain's amygdala—the alarm center—to stand down. When the alarm stops ringing, the seizure risk drops.
The "Perfect Storm" Scenario
Most of the time, a seizure is the result of a "perfect storm." It’s rarely just one thing.
Imagine you have a slight genetic predisposition to seizures. You haven't had one in years. Then, you get a flu (physical stress), you're going through a divorce (emotional stress), and you've been drinking too much coffee to stay awake (chemical stress). That combination is what usually does it.
We have to look at the "allostatic load." That’s the fancy medical term for the wear and tear on the body that accumulates when an individual is exposed to repeated or chronic stress. Your brain can only buffer so much before the circuit breaker flips.
Managing the Risk: Actionable Steps for a Calmer Brain
If you’re worried that your stress levels are putting you at risk, you can’t just "relax." If it were that easy, nobody would have this problem. You need a structural overhaul of how you handle the world.
First, track the patterns. Don't just rely on your memory—it's biased. Keep a "seizure and stress diary." Use a simple notebook or an app to log your mood, your sleep hours, and any "weird" sensations. Over a month, you'll likely see a pattern. Maybe you only have these episodes on Tuesday nights after your meeting with a specific manager. That’s data you can use.
Second, master the "vagus nerve" hack. The vagus nerve is the long wire that runs from your brain to your gut. It’s the "off switch" for stress. You can stimulate it through deep, diaphragmatic breathing—the kind where your belly moves, not your chest. When you feel that rising heat of stress, five minutes of 4-7-8 breathing (inhale for 4, hold for 7, exhale for 8) can literally chemically signal your brain that there is no lion chasing you.

Third, look at your environment. This is the hard part. If your job is literally causing you to have neurological events, no amount of yoga will fix the underlying issue. Sometimes, the medical advice isn't a pill; it's a lifestyle boundary.
Clinical Intervention and When to See a Pro
Look, if you've had a seizure, or even a "fainting spell" that felt weird, you need a neurologist. Period.
You need to rule out things like tumors, electrolyte imbalances, or true epilepsy. A doctor will likely want an MRI and an EEG. If the EEG comes back clear but the seizures keep happening during stress, ask about a referral to a neuropsychologist. These specialists are the bridge between the "hardware" (the brain) and the "software" (your emotions). They are the ones who specialize in treating PNES and stress-reactive epilepsy.
Moving Forward with Knowledge
The takeaway here isn't that you're "broken" or "weak" for having a physical reaction to stress. It's that your brain is incredibly sensitive to the environment you put it in.
Start by prioritizing sleep above almost everything else. It is your primary defense. Reduce caffeine intake if you notice it makes your anxiety—and your tremors—worse. Most importantly, stop viewing stress management as a luxury. For someone prone to seizures, it is a medical necessity, just like taking a prescription.
Ground yourself in the present. Use the 5-4-3-2-1 technique: find five things you see, four things you can touch, three things you hear, two things you smell, and one thing you can taste. This forces your brain out of the "future-worry" loop and back into the physical body. It’s a simple way to keep the electrical storm from ever starting.
