Managing disorders of consciousness: the role of electroencephalography

Abstract: Disorders of consciousness (DOC) are an important but still underexplored entity in neurology. Novel electroencephalography (EEG) measures are currently being employed for improving diagnostic classification, estimating prognosis and supporting medicolegal decision-making in DOC patients. However, complex recording protocols, a confusing variety of EEG measures, and complicated analysis algorithms create roadblocks against broad application. We conducted a systematic review based on English-language studies in… Show more

“…For example, they show a better association with consciousness compared to delta power (Frohlich, Toker, & Monti, 2021), alpha power (Esposito, Nielsen, & Paquette, 2004;Westmoreland, Klass, Sharbrough, & Reagan, 1975), or the P3b (Sergent et al, 2021). For this reason, measures of integration and differentiation, and their broad experimental validation as reliable indices of consciousness, are recognized as important advancements from a clinical (Bai, Lin, & Ziemann, 2020;Comanducci et al, 2020) and ethical (Bayne, Seth, & Massimini, 2020) standpoint; we think that they may also offer empirical ground for a more positive appraisal of their theoretical foundations. The groundbreaking, viewpoint theory of Merker et al explains several properties of the conscious field (the "conscious field" is defined as all that one is conscious of at one moment in time).…”

“…The use of high-density EEG (e.g., >60 channels) now provides a greater degree of spatial resolution ( 8 ). In addition to its clinical use in epilepsy, sleep disorders, and dementia with Lewy bodies ( 8 , 9 ), EEG has been used to investigate cortical activity and functional connectivity in stroke ( 10 , 11 ), consciousness disorders ( 12 ), Alzheimer's disease ( 13 ), Parkinson's disease ( 14 ), schizophrenia ( 15 ), and mood disorders ( 16 ).…”

“…Several quantitative approaches, with uneven complexity, of EEG signal post-processing and elaboration, have been applied, including the analysis of power spectrum, complexity, entropy, or functional/effective connectivity. All these measures have the aim of suitably defining the degree of the dysfunction associated with the impaired consciousness or predicting the outcome (see recent reviews of [2][3][4][5][6]).…”
