The unique metabolic profile of Sub-Saharan Africans and African Americans predispose them to a higher prevalence of type 2 diabetes (DM-2) and a 2-to-8fold increased risk of developing dementia compared to Caucasians. This increased risk places a significant strain on health systems. The development and progression of DM-2 are influenced by intrinsic factors such as sex, epigenetics, ethnicity, diet, and lifestyle, as well as extrinsic factors like socioeconomics, cultural nuances, and the environment. However, the complex relationship between diabetes and dementia is not fully understood; thus, further research efforts are needed. Our research group has identified educational level as a key risk factor for dementia, with Nigerian women being particularly affected. In this work, we studied both healthy individuals and those with DM-2 to search for a continuum between educational levels and cognitive function, and to establish education as a trigger factor for dementia prevalence. Our findings demonstrate that lower educational levels correspond to poorer cognitive function test results. Moreover, since women disproportionately have lower educational levels, their cognitive test results deviated more significantly from typical values. This study highlights the critical connection between education and dementia risk, emphasizing the urgent need to address gender education inequalities, particularly in sub-Saharan populations like Nigeria. By improving educational opportunities for women, we can potentially reduce the prevalence of dementia and enhance the overall quality of life in these communities. Addressing this issue is not only a matter of public health, but also a step toward achieving social equity and improving the resilience of health systems.
