Recommendations for research in Lewy body dementia relating to race, ethnicity, and ancestral considerations

Category	Considerations
Prevalence	Determine prevalence by geographic reasons and different people groups
Diagnosis	Identify barriers to symptom recognition or reporting Identify and address barriers to accessing healthcare for dementia Determine whether diagnostic criteria perform equally well across groups Develop and implement culturally sensitive neuropsychological test batteries Interpret cognitive testing with consideration of language, social determinants of health
Risk factors	Assess risk factors (e.g. environmental exposures) that may vary by geographic location (e.g. rural/urban) or background (e.g. vascular risk factors)
Observational studies	Include diverse cohorts Collect data on social determinants of health Assess biomarker validity across groups Increase diversity in brain bank studies
Clinical trials	Recruit diverse populations Identify ways to increase access to clinical trials for underrepresented groups (e.g. with regard to travel arrangements, stipends) Use measures with validated versions across different languages Employ culturally sensitive neuropsychological test batteries as outcome measures
