Alzheimer's electroencephalogram event scalp localization. In IEEE 9th International Workshop on Multidimensional (nD) Systems, nDS 2015. Vila Real. ISBN 978-1-4799-8739-9978-1-4799-8739-9http://hdl.handle.net/10198/16805Alzheimer’s disease (AD) is a neurodegenerative and incurable illness that causes intellectual functions decrease. This study is a new approach to improve the scalp brain anomalies localization associated with Electroencephalogram (EEG) energy variations of EEG threads (subsegments) sequencies sets found in AD patients by unsupervised learning techniques, called AD EEG temporal events. This study showed that AD patients have less brain dynamics than controls, because the AD EEG events propagation time over the scalp is higher and statistically different from control subjects (p<0.0022).engconference paper10.1109/NDS.2015.7332640
