Accuracy and Interobserver Reliability of Scalp Ictal EEG Neurol 42:2279-2285, Walczak,t.S.,et al, 1992 See this aricle in Pubmed Article Abstract When all seizures were analyzed,including those with generalized features or obscured by artifact,we determined side of seizure onset correctly in 76%to 83%of temporal seizures and 47%to 65%of extratemporal seizures.In most of the remainder,a lateralization judgement was impossible.When analysis was confined to those seizures in which lateralization was possible,we correctly lateralized 93%to 99%of temporal seizures. Interobserver reliability was excellent.RTA and PIF were more accurate than ASO.RTA was significantly more common in temporal seizures.Our data indicate that lateralization by scalp EEG is highly acccurate and reliable.
