An empirical quantitative EEG analysis for evaluating clinical brain death

Conf Proc IEEE Eng Med Biol Soc. 2007;2007:3880-3. doi: 10.1109/IEMBS.2007.4353180.

Abstract

In this paper, we apply qualitative tools and quantitative analysis for the EEG recordings of 23 adult patients. Specifically, independent component analysis (ICA) was applied to separate independent source components, followed by spectrum analysis. In terms of quantitative EEG analysis, we use several complexity measures to evaluate the differences between two groups of patients: the subjects in deep coma, and the subjects who were prejudged as brain death. For the first time, we report statistically significant differences of quantitative statistics in such a clinical study. The empirical results reported in this paper suggest some promising directions and valuable clues for clinical practice.
