Quantitative EEG effects of carbamazepine, oxcarbazepine, valproate, lamotrigine, and possible clinical relevance of the findings
UNLABELLED Quantitative EEG ( QEEG ) effects of therapeutic doses of carbamazepine ( CBZ ) , oxcarbazepine ( OXC ) , valproate ( VA ) and lamotrigine ( LA ) monotherapy were investigated in patients with beginning epilepsy . Baseline waking EEG ( EEG1 ) was recorded in the untreated state , the second EEG ( EEG2 ) was done after 8 weeks of reaching the therapeutic dose . Left occipital data were used for analysis . QEEG target parameters were absolute b and -power ( delta : AD , theta : AT , alpha : AA , beta : AB ) , and alpha mean frequency ( AMF ) . Group effects ( untreated versus treated condition in the CBZ , VA , OXC , LA groups ) were computed for each target parameter . One group with benign rol and ic epilepsy remained untreated for clinical reasons and served to estimate the QEEG test-retest differences . In addition , the individual QEEG response to each drug was calculated as ( EEG2-EEG1 ) . RESULTS statistically significant ( p<0.05 ) group differences indicated the QEEG domain systematic ally affected by the drugs . CBZ caused AT increase and AMF decrease . OXC caused AMF decrease . VA and LA did not decrease AMF ( LA even increased it ) , but reduced broad-b and power . Individual power and AMF changes showed considerable variability in each group . > 0.5 Hz AMF decrease ( that was reported to predict cognitive impairment in prior studies ) occurred in 10/41 patients in the CBZ group but never in the OXC , VA , LA groups . The results may be utilized in planning further studies addressing the relationship between antiepileptic drugs and their CNS effects . In addition , the relationship of AED-related cognitive impairment and AMF changes was discussed
