[Electroencephalography and connectivity in delirium]
Background:
Delirium is associated with neurophysiological changes that can be identified with quantitative EEG analysis techniques (qEEG).
Aim:
To provide an overview of studies on neurophysiological changes in delirium using various qEEG analysis techniques.
Method:
Literature review.
Results:
In delirium, there is an increase in delta and theta activity but a decrease in activity in the alpha frequency band. Additionally, there is a decrease in functional connectivity and efficiency of the brain network in the alpha frequency band.
Conclusion:
Delirium is characterized by diffuse slowing of the EEG, reduced functional connectivity, and decreased efficiency of the brain network. Improved functional connectivity could be a new approach to treat delirium.
