Common Seizure Triggers

By Dovy Paukstys, Founder, Komori Care

This article is educational and is not medical advice. It does not diagnose, treat, prevent, or cure any condition. Komori is not a medical device, is not FDA-cleared, does not detect seizures, and is not intended for people with epilepsy. Talk with a neurologist or epileptologist about personal medical decisions. Households living with epilepsy should use clinically validated seizure-detection devices as directed by their care team.

People treat "trigger" like it means "cause." It doesn't.

NINDS is blunt. Seizure triggers do not cause epilepsy. They can provoke a seizure in someone who is already susceptible. If you're already diagnosed and on medicine, a trigger can still spark one.

I don't have epilepsy. I read the CDC and NINDS pages because friends do, and because the internet turns this topic into a 40-item cleanse list. CDC's list is short. I'm staying on that list.

This is education. Not a treatment plan. Not a permission slip to stop a drug. Not a "just sleep more" speech.

What CDC puts on the list

CDC's health and safety page says some people with epilepsy know what brings a seizure on. People have different triggers. Knowing yours, and avoiding it when you can, matters for managing epilepsy.

Their list:

Lack of sleep.

Missing medication.

Stress.

Alcohol, illegal drugs, or prescription drugs used in ways other than prescribed.

Flashing lights or certain sounds.

Hormonal changes with a period or pregnancy.

That's the public list. I'm not adding essential oils.

What NINDS adds

Same idea, a few more lines. Stress. Drinking alcohol, or alcohol withdrawal. Dehydration or missing meals. Toxins and poisons, including lead, carbon monoxide, illicit drugs, and very large doses of prescription medicines. Hormonal changes with the menstrual cycle. Sleep deprivation. Visual stimulation like flashing lights or moving patterns.

In surveys of people with epilepsy, stress is the most commonly reported trigger. NINDS says that out loud. Doesn't make stress the villain of every case. It means a lot of people report it.

Sleep deprivation gets extra language. NINDS calls it a powerful trigger. Sleep disorders are common in this population. Treating sleep problems can help reduce seizures. Their hygiene list is boring on purpose. Same bedtime. Same wake time. Fewer distractions in the bedroom. No big meals or exercise within a few hours of bed.

CDC's managing-epilepsy page wants 7 to 8 hours. Track seizures. Pay attention to the things that can trigger them so you can avoid them if possible. Limit alcohol. Don't use other people's prescriptions. Take the seizure medicine as prescribed.

None of that is a protocol I wrote. It's their page.

Missed medicine is not a lifestyle tip

CDC puts missing medication on the trigger list for a reason.

Their treatment page is not cute about it. Do not skip or stop seizure medicine without talking to the provider. Suddenly stopping can cause withdrawal, including life-threatening seizures. Taking the medicine is "the most important thing you can do to prevent seizures," their words.

NINDS says the same from the other side. Discontinuing too early is a major reason people who were seizure-free start having seizures again. It can lead to status epilepticus. Stopping is a clinician decision.

If someone on the internet tells you to "taper yourself" because a podcast mentioned magnesium, close the tab.

Alcohol

CDC: alcohol is on the trigger list. Their living-with page says limit intake. NINDS: drinking, or withdrawal, can provoke a seizure.

I'm not writing a drink count. CDC has adult general-population limits on that page if you want them. The epilepsy-specific point is simpler. Alcohol is a documented trigger for some people. Withdrawal is too. Your neurologist gets a veto.

Lights

Photosensitivity is real for some people and over-claimed for everyone else.

CDC lists flashing lights or certain sounds. NINDS lists flashing lights or moving patterns. That is not "all screens are dangerous" and it is not "only raves." It's a subset. If lights are a problem for this person, the clinician says so. If they aren't, don't build a life around a trigger you don't have.

lol at the comment sections that diagnose photosensitivity from one TikTok.

Stress, sleep, hormones

Stress is the most reported trigger in the NINDS surveys. CDC lists it. Their living-with page also says practice ways to lower stress and get help for emotional problems. Depression and anxiety show up a lot in this population. That's a clinician and a therapist, not a breathing-app receipt.

Sleep I already covered. Powerful trigger. Treat the sleep problem if there is one. Don't heroically pull all-nighters and call it fine.

Hormones. CDC: period or pregnancy. NINDS: menstrual cycle. Catamenial patterns exist for some women. Pregnancy decisions sit with a neurologist and an obstetrician. I'm not freelancing that.

What a trigger is not

Not the diagnosis. Not proof you "brought it on yourself." Not a substitute for medicine.

A provoked first seizure from a temporary medical insult (fever, acute head injury, alcohol withdrawal as an acute event) is a different conversation from "I have epilepsy and last night I slept three hours." NINDS and CDC keep those ideas apart. I am keeping them apart.

Tracking helps some people see a pattern. CDC says track seizures. A pattern is still not a treatment plan. You take the notebook to clinic.

What I will not do here

I will not rank triggers. I will not tell you to change a dose. I will not pretend a consumer gadget "catches" a trigger night and prevents a seizure.

If you live with epilepsy, the care team owns the plan. Clinically validated seizure-detection tools only if that team directed them. Everything else is noise.

FAQ

Do triggers cause epilepsy?

No. NINDS: triggers do not cause epilepsy. They can provoke a seizure in someone who is susceptible.

What triggers does CDC list?

Lack of sleep, missing medication, stress, alcohol or drugs used other than prescribed, flashing lights or certain sounds, and hormonal changes with a period or pregnancy.

Is missing a dose a trigger?

CDC lists missing medication as a trigger. Their treatment page says do not skip or stop seizure medicine without the provider, because sudden stops can cause withdrawal including life-threatening seizures.

Should I build a treatment plan from this page?

No. Education. Your neurologist or epileptologist builds the plan. This page is a glossary of what the federal pages actually name.
