| Abstract |
Purpose
: This study was performed to correlate clinical behaviours with either a temporal or
frontal site of origin and then to identify behaviours that might have a significant practical value
in differentiating a temporal from a frontal focus and thus reduce the need for invasive
monitoring.
Methods
: We analysed 129 seizures that occured during video-EEG monitoring in 13 patients
with temporal lobe epilepsy(TLE) and in 9 patients with frontal lobe epilepsy(FLE) as well as
neuroimaging studies. We compared first the clinical behaviours that occurred in frontal lobe
seizures to those of temporal lobe seizures(second stage analysis). To eliminate clinical behaviours
that could occur as the discharge propagated another lobe, we compared only clinical seizure
events in which we had no evidence of spread to other regions, or that spread only to the
homologous contralateral lobe(first stage analysis). The Fisher exact test was used for analysis.
Results
: Although staring, sitting up, leg movement, and tonic-clonic movement, generalization
occurred more frequently in FLE, and oral, alimentary and hand automatisms were more frequent
in TLE, no statistically significant difference was found between the two groups. In second stage
analysis, sitting up, tonic-clonic movement were seen only in FLE and oral, alimentary and hand
automatisms only in TLE. Staring, hand posturing occurred more frequently in FLE.
Conclusion
: We therefore conclude that the reliability of clinical behaviour alone to predict the
site of origin of an epileptic discharge is limited when the surface EEG is equivocal or neuroradiologic
evidence of a focus is not clear. |
