The widespread use of the routine EEG in clinical practice was a major development in the treatment of patients with ill-defined spells thought to be epileptic. Not every finding on the EEG is suggestive of epilepsy, and the EEG is subject to over-interpretation, which may lead to misdiagnosis and incorrect treatment. Although supplemented by other procedures, the EEG remains a cost-effective and noninvasive way to diagnose spells. To enhance further the diagnostic use of the EEG, it is important to determine how strongly patterns are correlated with clinical seizures. The authors studied one EEG pattern, lateralized bursts of theta, and found the rhythmicity of the pattern to be most strongly correlated with seizures.
常规脑电图在临床实践中的广泛应用是治疗那些被认为患有癫痫但症状不明确的患者方面的一项重大进展。脑电图上的每一项发现并非都提示癫痫，而且脑电图容易被过度解读，这可能导致误诊和错误治疗。尽管有其他检查手段作为补充，但脑电图仍然是一种诊断发作性症状性价比高且无创的方法。为了进一步提高脑电图的诊断价值，确定脑电图模式与临床癫痫发作的关联强度很重要。作者研究了一种脑电图模式，即θ波的单侧爆发，并发现该模式的节律性与癫痫发作的关联最为密切。
