Modified Atkins Diet

Less restrictive variant of the ketogenic diet that may provide seizure control while allowing more food variety. Evidence supports its use in generalized epilepsy syndromes.

dietary

Seizure Trigger Avoidance

Identification and avoidance of individual seizure triggers including stress, flashing lights, sleep deprivation, and dehydration. Structured daily routines help minimize variability that may precipitate seizures.
