Abstract: Highlights•We create lifespan Riemannian qEEG norms for cross-spectral tensors.•EEG from 1564 subjects provided by 9 countries, 12 devices, and 14 studies were used.•We demonstrate qEEG “batch effects”, providing harmonization methods to remove them.•Multinational harmonized z-scores increase diagnostic accuracy of brain dysfunction.•Data and software are available for norm and individual z-scores calculation.
