Clorazepate therapy for intractable epilepsy.

Thirty-one epileptic patients with seizures refractory to conventional anticonvulsants were treated by adding clorazepate dipotassium to their regimen. Twelve cases showed improvement in seizure frequency, three of whom attained a seizure free state. Response to clorazepate was not related to the type of epilepsy, but patients with secondary generalized epilepsy tended to be less responsive than those with partial epilepsy. Among the various seizure types, generalized tonic-clonic seizures and simple partial seizures showed, although not significant, a tendency to be more responsive to clorazepate therapy than other seizure types, including complex partial seizures, atypical absence, atonic seizures, and tonic seizures. Drowsiness was the main adverse effect, of which 14 patients complained. Six patients were withdrawn from clorazepate because of drowsiness, but in the remaining 8 patients, this side effect disappeared within a week. The appearance of adverse effect was not related to the dose of clorazepate given. Clorazepate may be an effective secondary anticonvulsant in the treatment of intractable epilepsy.

Developmental changes of brainstem auditory evoked potentials (BAEPs) in normal human subjects from infants to young adults.

BAEP has been found to be useful for assessment of subcortical maturation. However, the precise maturational changes of the peripheral and central transmission in normal human subjects are still open to controversy. We obtained a total of 200 BAEPs from 165 normal human subjects ranging from infants to young adults. Electrodes were placed at both mastoids and the reference at the vertex. 85 dB SL click stimuli were presented binaurally at a rate of 13/sec and 2,048 responses were summated on line with an averager. Investigation of the maturation of the transmission time indicated that the peripheral auditory apparatus attains functional maturity during the first 2 months of life, whereas the central transmission time shortens up to the age of 5 to 8 years. III-II and V-IV interpeak latencies (IPLs) showed maturational changes similar to those of V-I IPLs, in contrast II-I and IV-III showed little changes. A clear increase of the amplitude of peak V up to 4 years of age and a subsequent decreasing tendency was observed. The V-I IPLs of males were longer than those of females in each age group. Females also displayed larger BAEPs for wave V than males after 2 years of age. These data indicate that it is worthwhile to have separate latency and amplitude norms for males and females from infants to adults for attaching diagnostic significance to BAEP measures.
