Gabapentin (GBP) is an effective drug in the treatment of refractory p
artial epilepsy, but the effect of GBP on the electroencephalogram (EE
G) has not been studied. Serial EEGs were performed in 25 patients wit
h refractory partial epilepsy, who took part in an open clinical trial
of GBP as add-on therapy. About an equal number of patients had no ch
ange, better EEGs, and worse EEGs. Correlation was poor between EEG ch
anges and change in seizure frequency. Thus, inclusion of EEGs in the
protocol of a drug trial for epilepsy is probably not beneficial.
