Comparison of the effects of vigabatrin, lamotrigine, and topiramate on quantitative EEGs in patients with epilepsy.
Information on the effects of newer antiepileptic drug ( AEDs ) on the electroencephalogram ( EEG ) is sparse and contradictory . Quantitative EEG ( qEEG ) provides a method of estimating the effects of drugs on the central nervous system . Twenty-three adult patients with difficult-to-control complex partial seizures , with or without secondary generalization , participated in an add-on study with one of three newer AEDs : vigabatrin ( n = 10 ) , lamotrigine ( n = 6 ) , and topiramate ( n = 7 ) . Frequency analysis and topographic mapping of awake EEGs before and during treatment with the drug were compared . Statistical analysis was performed using 2-way analysis of variance ( ANOVA ) with repeated measures . Vigabatrin administration was followed by a diffuse decrease in the absolute alpha ( p < 0.05 ) and beta ( p < 0.02 ) activities and a decrease in the absolute theta in the frontal and parieto-occipital regions ( p < 0.03 ) . Lamotrigine caused a significant diffuse increase in the faster frequencies ( relative alpha p < 0.04 and relative beta p < 0.02 ) , and decrease in the slower activities ( relative theta in the posterior head regions p < 0.03 and relative delta diffusely p < 0.05 ) . Topiramate increased the absolute beta ( p < 0.05 ) and theta ( p < 0.02 ) activities diffusely and decreased the relative alpha activity over the left hemisphere ( p < 0.03 ) . The different effect profiles of the newer AEDs on the electrical brain activity may reflect their different mechanisms of action
