The relationships between ethnoracial identity, Aβ positivity, APOEε4, and medial temporal lobe tau PET.

Key Points

• To investigate whether factors beyond amyloid and tau influence cognition in specific ethnoracial groups.
• Analyzed relationships between ethnoracial identity, Aβ positivity, and APOEε4 status.
• Utilized tau PET imaging to assess medial temporal lobe tau levels.
• Focused on Black participants to uncover ethnoracial differences.
• Identified that cognition may be influenced by factors other than amyloid and tau.
• Highlighted the need for further investigation into off-target effects related to Ethnoracial differences.
