Abstract
The invention relates to a method for detecting a change in a patient's physiological condition with respect to a reference physiological condition. The method is based on a multimodal analysis that involves measurements of electroencephalography signals Si from the patient and at least one other physiological signal SN+1(N≥1) from the patient. Based on these measurements, the invention proposes calculating distances di(m) associated with the electroencephalography measurements and with the measurements of the other physiological signals and fusing these data, the data having previously undergone a certain number of mathematical processing operations. In the context of the invention, the fused data may be assigned a weighting coefficient chosen according to one or more a priori or a posteriori criteria.
