Panayiotopoulos syndrome (PS) was first described by and later named after Greek epileptologist Chrysostomos Panayiotopoulos in the late 1980s. A common benign childhood epilepsy, PS is estimated to make up 13% of all cases of epilepsy in children aged 3–6 years, though it can be seen also during teenage years. It is also known as early-onset childhood occipital epilepsy as opposed to the late-onset childhood occipital epilepsy known as Gastaut syndrome. They are all subtypes of benign focal epilepsies of childhood.
