  • Identification of the Temporal Components of Seizure Onset in the Scalp EEG
    作者:Nora S. O'Neill、Zoltan J. Koles、Manouchehr Javidan
    DOI:10.1017/s0317167100001402
    日期:2001.8
    Background:

    The identification of the earliest indication of rhythmical oscillations and paroxysmal events associated with an epileptic seizure is paramount in identifying the location of the seizure onset in the scalp EEG. In this work, data-dependent filters are designed that can help reveal obscure activity at the onset of seizures in problematic EEGs.

    Methods:

    Data-dependent filters were designed using temporal patterns common to selected segments from pre-ictal and ictal portions of the scalp EEG. Temporal patterns that accounted for more variance in the ictal segment than in the pre-ictal segment of the scalp EEG were used to form the filters.

    Results:

    Application of the filters to the scalp EEG revealed temporal components in the seizure onset in the scalp recording that were not obvious in the unfiltered EEG. Examination of the filtered EEG enabled the onset of the seizure to be recognized earlier in the recording. The utility of the filters was confirmed qualitatively by comparing the scalp recording to the intracranial recording and quantitatively by calculating correlation coefficients between the scalp and intracranial recordings before and after filtering.

    Conclusion:

    The data-dependent approach to EEG filter design allows automatic detection of the basic frequencies present in the seizure onset. This approach is more effective than narrow band-pass filtering for eliminating artifactual and other interference that can obscure the onset of a seizure. Therefore, temporal-pattern filtering facilitates the identification of seizure onsets in challenging scalp EEGs.

    背景:识别与癫痫发作相关的节律性振荡和阵发性事件的最早迹象,对于确定头皮脑电图中癫痫发作的起始位置至关重要。方法:利用头皮脑电图发作前和发作期部分所选片段的共同时间模式设计了数据依赖性滤波器。结果:将滤波器应用于头皮脑电图,发现了头皮记录中癫痫发作开始的时间成分,而这些成分在未经滤波的脑电图中并不明显。对过滤后的脑电图进行检查,可以在记录中更早地识别出癫痫发作的起始时间。通过比较头皮记录和颅内记录,对滤波器的效用进行了定性确认;通过计算头皮记录和颅内记录在滤波前后的相关系数,对滤波器的效用进行了定量确认。与窄带通滤波器相比,这种方法能更有效地消除可能掩盖癫痫发作起始点的假性干扰和其他干扰。因此,时间模式滤波有助于在具有挑战性的头皮脑电图中识别癫痫发作的起始点。
