3

Sleep Regularity and Trigger Avoidance

Implementing consistent sleep schedules and avoiding known seizure triggers such as sleep deprivation, alcohol, and flashing lights that can precipitate absence seizures in susceptible individuals.

Additional treatment options

Video EEG Monitoring

Diagnostic monitoring to confirm diagnosis, characterize seizure types, and assess treatment response. Particularly valuable when diagnosis is uncertain or seizures persist despite treatment.

monitoring

Modified Atkins Diet

Less restrictive alternative to ketogenic diet that may help control seizures in some patients. Involves carbohydrate restriction with adequate protein intake.
