The global rise of neurodegenerative disorders calls for equitable and scalable approaches to identify and characterize patients. Numerous linguistic tools can now reveal early disease-specific markers, predict disease progression, and differentiate among disease phenotypes. Considering the vast variety of languages and cultures worldwide, integrative cross-national efforts can foster a fairer development of neurolinguistic markers for diagnosis and treatment. Include aims to integrate multidisciplinary teams across the globe to promote cross-linguistic and cross-cultural research on various brain diseases.
