Research indicates that dementia cases in the U.S. are expected to double in the coming decades, reaching 1 million diagnoses per year by 2060. The prevalence of dementia risk is notably rising among the aging population, with projections suggesting that two in five Americans over the age of 55 will face a lifetime risk of developing the disease. Factors contributing to this increase include lifestyle choices, with studies highlighting both the risks and preventive measures that can be adopted to reduce the likelihood of dementia. Experts emphasize that while living longer may correlate with higher dementia rates, proactive steps can mitigate this risk.
