Seizure triggers

For some people, certain situations can trigger (set off) a seizure. Common triggers include lack of sleep, stress, alcohol, and not taking their prescribed anti-seizure medication (ASM).

Less commonly, seizures can be triggered by flashing lights or moving patterns (called photosensitive epilepsy). It may be possible to avoid triggers if they can be identified.
