Triggers vary from person to person.  

Some people with epilepsy are able to very clearly identify situations that trigger a seizure, while others are unable to find a pattern to their seizures.

A common way to identify seizure triggers is to keep a seizure record that includes tracking what happens before each seizure.

COMMON TRIGGERS INCLUDE:
What triggers epilepsy

Missed doses of anti-seizure medication (most common trigger)

Lack of sleep or fatigue

Stress or excitation

Photosensitivity / flashing lights or contrasting patterns

Alcohol

Hormonal changes during the menstrual cycle

Colds, flu or some kinds of infection

Elevated body temperature
