Method and system for determining a parameter indicating whether a patient is in a delirium state

摘要

A method for determining a parameter indicating whether or not a patient is in a delirium state or at risk of becoming a delirium, for a predetermined period of time, for example 10 seconds, from at least two different positions on the patient's scalp Electroencephalogram (EEG) data including a recording signal representing brain activity, wherein at least one said signal supplies EEG data that is a recording of the first half of the scalp, and processing the EEG data from the electrodes In the process of obtaining the difference signal from the two recorded signals, analyzing the difference signal in the frequency spectrum, verifying the slowing of the difference signal, and defining the parameter as the degree of slowing of the difference signal And wherein the parameter is combined with a recorded position on the patient's scalp to indicate whether or not the patient is or is at risk of becoming delirium.
