The include network: Advancing cross-linguistic equity in brain health research

Area of Science:

• Neuroscience
• Linguistics
• Global Health

Background:

• Speech and language measures show promise as non-invasive biomarkers for brain disorders.
• Current research is predominantly English-focused, limiting global applicability.
• Linguistic diversity is underrepresented in brain health research.

Purpose of the Study:

• To introduce the International Network for Cross-Linguistic Research on Brain Health (Include).
• To address the gap in global applicability of speech and language markers due to linguistic bias.
• To foster equitable and globally relevant brain-health research.

Main Methods:

• Review of Include's origins, mission, and organizational structure.
• Summary of key milestones over the network's first four years.
• Highlighting flagship projects on linguistic typology and culture's impact on neurodegeneration markers.

Main Results:

• Established a multicentric initiative (Include) to bridge the research gap.
• Achieved milestones in cross-linguistic studies, data governance, and global dissemination.
• Demonstrated how language and culture influence speech-language markers of neurodegeneration.

Conclusions:

• Include serves as a strategic platform for inclusive, global brain health research.
• Addressing language underrepresentation and tool harmonization is crucial for the field.
• Expansion beyond neurodegeneration is a key future opportunity for the network.
