title: Limitations in the medical treatment of cryptogenic or symptomatic localization-related epilepsies of childhood onset.
abstract: We retrospectively examined 169 patients who had cryptogenic or symptomatic localization-related epilepsies (LRE) and were followed-up for more than 5 years. The probability of seizure control was 0.13 during the first year of treatment, 0.25 during the first 5 years, and 0.09 during the second and third 5 years. No patients who continued to have intractable seizures for 15 years became free of seizures. The onset of LRE at the age of 3 years or less, seizure cluster, mesial temporal sclerosis (MTS), and temporal lobe epilepsy (TLE) were significantly associated with a poor seizure control. If an antiepileptic drug (AED) failed to control seizures, probability of seizure control by the next drug was low, in particular in patients in whom more than 4 AEDs have already been tried, and seizure control could not be expected after a trial of 6 AEDs. A tentative indication of epilepsy surgery for LRE of childhood onset may be 5 years of poor seizure control and/or failure of four AEDs.
