Summary
Benign variants should be distinguished from epileptogenic and ictal patterns to prevent misdiagnosis of epilepsy. Variants are identified based on their appearance, typical location, state, and age group. Antiepileptic medications such as valproic acid or levetiracetam may blunt epileptic discharges and reduce their amplitude, making them less distinct from the surrounding background. These can be mistaken for normal variants.
