title: [Efficacy and limitations of antiepileptic drug monotherapy for temporal lobe epilepsy].
abstract: To evaluate the efficacy of antiepileptic drug (AED) monotherapy, we studied 147 patients with temporal lobe epilepsy (TLE) aged 15 or older who had been undergoing treatment at our hospital for at least five consecutive years. We divided the treatment time into Period I which included one year beginning six months after the initial diagnosis, and Period II which was the two years from January, 1987 to December, 1989. The efficacy of therapy was evaluated for the two periods based on the following standards: effective, if seizures had been controlled, and ineffective, if at least one seizure had occurred during each period. Patients in whom monotherapy was effective increased by a factor of 1.7 over the period of observation, from 38 cases (28%) in Period I to 65 cases (44%) in Period II. The total number of effectively treated cases (including those on polytherapy) also rose from 58 cases (40%) in Period I to 79 cases (54%) in Period II. The average number of AEDs used was reduced from 3.0 +/- 1.3 at the time of initial diagnosis to 1.8 +/- 0.8 in Period I and 1.6 +/- 0.8 in Period II. When compared with the 68 ineffectively treated cases, significant background factors for the 65 effectively treated cases on monotherapy included: higher age at ictal onset, fewer histories of any previous treatment at initial diagnosis, or of encephalitis or febrile seizures, fewer psychological impairments such as cognitive degeneration or personality disorders, lower frequency of seizures, fewer histories of secondary generalization or automatism, and a higher rate of normal findings of background EEG and cerebral CT.(ABSTRACT TRUNCATED AT 250 WORDS)
