Its diagnostic accuracy is relatively low and there is not a biomarker able to detect AD without invasive tests. This study is a new approach to obtained electroencephalogram (EEG) temporal events in order to improve the AD diagnosis. For that, K-means were used and the results suggested that there are sequences of EEG energy variation that appear more frequently in AD patients than in Health subject.engAlzheimer’s diseaseElectroencephalogramTemporal eventsSequencesK-meansconference object10.1016/j.protcy.2012.09.095
