Abstract:
Objective To investigate the influence of topiramate(TPM) on quantitative pharmacoelectroencephalography (QPEEG) in normal subjects and epilepsy patients. Methods EEG were recorded in normal and epileptic subjects prior to and at 0.5,1,2,4,6,8,12,24 hours after the administration of single dose of TPM.The EEG power spectral activity including the absolute power,percent of power,total power in both occipital and total power of the whole scalp areas were calculated through 30 s epochs without artifacts after each recording.The statistical difference between baseline assessment and each post-drug time point was analyzed by the Wilcoxon matched-paired rank test. Results The power of sloe wave(peak value 66.76 ?V 2),?1-band (peak value 57.33 ?V 2)and total power (peak value 385.12 ?V 2)was increased after the administration of TPM and the total power of the whole scalp areas was also increased(peak value 2 500.75?V 2).The percent of power of ?-band(peak value 12.4%) and ?1-band(healthy control,peak value 17.5%) or ?-band(patient,peak value 13.94%)was increased,while ?3-band(healthy control,lowest value 10.4%) decreased. Conclusion TPM might change the background activity of EEG that was different from other antiepilepsy drugs.
