Common Seizure triggers: What are they and how to recognise them?

If you have witnessed a seizure, you know how nerve-racking the situation can feel. If you have had a common seizure trigger, you know they can be difficult to explain to others.

Even if you have never experienced a seizure yourself, you could easily become a bystander to a person who does. Be prepared by knowing how to recognise a seizure so you can take the right steps.

Triggers vs. causes: What’s the difference?

Seizure causes and seizure triggers are different. Triggers are situations that can bring on a seizure. For example, sleep deprivation can be a trigger while the underlying cause may be a head injury.

The leading causes of a seizure generally involve some sort of injury to the brain. Epilepsy is a term for the tendency to have more than one unexplained seizure. A person is usually only diagnosed with epilepsy after they have had more than one seizure.

Here are some common causes of seizures:

  • Head injuries that occur during birth

  • Low oxygen during birth

  • Head injuries during youth or adulthood

  • Brain tumours

  • Genetic conditions

  • Infections such as meningitis or encephalitis

  • Stroke

  • Abnormal levels of substances such as sodium or blood sugar

People that experience seizures or have epilepsy report different triggers. While the triggers do vary, here are some commonly reported ones.

  • Lack of sleep

  • At times of fevers or illness

  • During alcohol or drug use

  • Stress

  • Hormonal changes such as menstrual cycles

  • Metabolic problems

  • Use of certain medications

  • Specific foods

  • Excess caffeine

  • Low blood sugar

  • Flashing bright lights

  • Certain sounds

  • During specific times of the day or night

How to tell if something is a common seizure trigger?

It can be tricky to work out what is truly a trigger and what is purely a coincidence. It can help to look at possible warning signs. Take these steps to obtain a better understanding of what is truly triggering your seizures.

Take note of:

  • The time of day the seizure occurs

  • How long the seizure lasted

  • Any special situations surrounding the time of your seizure

  • How you feel or felt during and after the seizure

  • Anything you ate or consumed before the seizure occurred

  • Anything that might have changed in your regular environment

Using the Seer app is a great way to record the frequency of your seizures and take note of your possible triggers or symptoms.

Can a seizure be triggered even if you don’t have epilepsy?

Not everyone who has seizures has epilepsy. Both epileptic and non-epileptic seizures can be brought on by triggers. Here are some common triggers of non-epileptic seizures.

  • Stress, anxiety, or underlying trauma

  • Low blood sugar

  • Heatstroke

  • Alcohol withdrawal

  • Taking certain medications

  • Sleep deprivation

When should you consult with your doctor if you experienced a common seizure?

If you have experienced a seizure, consult with a doctor immediately. This is crucial if you have had more than one or if they last more than a few minutes. It is also a good idea to talk to your doctor if you experience any warning signs.

Track the events surrounding your event and discuss this with your doctor. Providing this information will help both you and your doctor to discover what may be triggers and come up with ways to proactively avoid them.

Your doctor will most likely order some tests to monitor your heart and brain activity. These tests will be able to detect if anything comes up as unusual in your heart or brain activity. Following these tests, your doctor will determine if any medical treatment is needed.
