Today’s Story

A recent study by NYU Langone Health reveals that the risk of developing dementia for Americans over 55 is significantly higher than previously estimated, with rates at 35% for men and 48% for women. This study predicts that the number of new dementia cases will rise from around 514,000 in 2020 to about 1 million by 2060 due to an aging population and factors like high blood pressure, diabetes, obesity, unhealthy diets, sedentary lifestyles, and poor mental health. 

Women, seniors (especially those over 75), black adults, and carriers of the APOE 4 gene are at particular risk. The median age for dementia diagnosis is 81 years, and there’s currently no cure, though early detection and lifestyle adjustments, such as managing blood pressure and addressing hearing loss, can help mitigate risks. Dr. Josef Coresh emphasizes the importance of greater access to healthcare and addressing racial inequities.
