Electrophysiological examinations constitute objective
and accurate measures of cerebral function. They can
be recorded at bedside, which is of major value in intensive
care units. The objective of the present study considers the
linear and non-linear analysis of resting electroencephalography
(EEG) signals as predictors for poor outcome and differences
between brain regions. We studied 24 brain injured
patients (trauma, cerebral anoxia, intracranial haemorrhage,
cerebral infections) and 12 healthy controls and compared
their EEG power spectra, the zero crossing and fractal dimension
splitting the brain in four regions: left hemisphere, right
hemisphere, anterior cortex, posterior cortex. In this study
early linear and non-linear parameters showed the ability to
predict recovery of communicative skills in brain injured
patients at 6 months
