Migration Effects on Cognition: Protocol for the Aging in Kerala Americans Research Study.
Article in JMIR research protocols, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundIn the United States, Asian American people represent the fastest growing population group, and are highly diverse linguistically, culturally, and demographically. Yet, in most national studies, Asian American groups are aggregated, masking potential health disparities. Racial and ethnic minorities, especially first-generation immigrants, are also at a particularly elevated risk of cognitive impairment.
objectiveThe Aging in Kerala Americans Research (AKKARE) study aims to examine both positive and negative migration effects on health in the first-generation Kerala American population, focusing on cognition and dementia. We will assess the effect of immigrant and cultural factors and social relations on cognitive aging from epidemiological, biological, and vascular perspectives. This protocol describes the study design and procedures for the AKKARE study.
methodsThe AKKARE study proposes to enroll 400 older first-generation Kerala American individuals from the tristate area. A smaller subset of these participants will complete blood tests (n=360) and neuroimaging studies (n=160). We will assess the role of immigration and cultural effects on cognitive function, mood, and quality of life, as well as biological and vascular aging. We will conduct follow-up assessments at 12-month intervals for up to 5 years.
resultsThe AKKARE study (grant #1R01AG084567-01) was funded by the US National Institutes of Health in 2024 and received approval from the Stony Brook University Institutional Review Board to start the study in 2025. Enrollment began in September 2025.
conclusionsAs there is presently a lack of fundamental data on the epidemiology in diseases of aging in Indian American immigrants, the AKKARE study will provide new insights into factors of risk and resilience associated with cognitive impairment in this group and in the broader older adult population.
