Dementia cases in US projected to rise dramatically by 2050, study finds

Increase will add strain on healthcare system already struggling amid cuts by Trump administration, experts say

The number of people with dementia in the United States is projected to increase dramatically over the next 25 years, which will place increasing strain on a healthcare system already struggling to help them amid cuts by the Trump administration, experts say.

According to a new study in Jama Neurology, the annual incidence of new dementia cases globally will more than double, from 11.4m in 2023 to 24.7m in 2050. In the United States, the number of adults diagnosed with dementia each year will increase from 514,000 in 2020 to 1m by 2060, according to a Jama study published in 2024.
