Background: Evidence suggests that modifiable risk factors which can be targeted by prevention are vascular diseases, such as diabetes, midlife hypertension (HTN), midlife obesity, midlife cholesterol, mid- and late-life depression as well as lifestyle factors such as smoking, physical inactivity, and poor diet. Methods: A comprehensive search of the National Library of Medicine's PubMed database and Google Scholar was conducted. A combinations of medical subject headings and free text words that included search terms related to the exposure (e.g., prevalence, HTN, raised BP, high BP, diabetes, high blood sugar, DM, India, state), were combined with search terms related to the outcomes (e.g., prevalence, disease burden, estimate, dementia, India). The filters included were English for the language category and humans for the study category. Results: The PubMed search initially identified 269 references, and a total of 204 abstracts were screened by inclusion criteria. Full-text assessment of 136 articles on prevalence of dementia resulted in 20 relevant articles from which the different regions of the country were identified. Based on the search conducted according to the regions; 287abstracts of the prevalence of HTN and 577 on the prevalence of diabetes mellitus were screened. There were 43 full-text articles on the prevalence of HTN and diabetes from the regions where the prevalence of dementia was available. Of these potentially relevant articles were 14 in number. Conclusion: Despite the uncertainty in the role, the data analysis, therefore, points to a role in the prevention of HTN and diabetes to prevent dementia.
