The objective is to examine cognitive decline and dementia prevalence across various U.S. regions, focusing on gender, age, and race/ethnicity disparities. Using data from the Behavioral Risk Factor Surveillance System (BRFSS), collected from 2015 to 2021, 59 locations were categorized into Northeast, Midwest, Southeast, Southwest, and West regions. The original dataset contained 31 attributes. The analysis included year-wise trend examination, gender-wise, age-wise, and race-wise distribution assessments, and identification of key risk factors. The Midwest (21.98%) and West (21.83%) showed higher cognitive decline rates, with significant disparities across demographics. The ‘Overall’ age group showed the highest prevalence at 8.54%. Females were most affected, with diabetes, asthma, arthritis, depression, and cardiovascular diseases being the most correlated comorbidities.
