Currently, an estimated 6.7 million Americans are living with Alzheimer’s – which is one of the 15 leading causes of death in America.

Alzheimer’s Disease on the Rise in South Dakota

24/7 Wall St. looked at the latest projected data from the 2023 Alzheimer’s Association’s Alzheimer’s Disease Facts and Figures report and from the U.S. Census Bureau’s 2021 American Community Survey to compile a list of States Where Alzheimer's Is Expected to Soar by 2025.

In the Tri-State Area (South Dakota, Iowa, Minnesota), two states are among the places where the disease is expected to grow at a much slower rate than the rest of the country.

Even though Alzheimer's is projected to expand by more than 10 percent in the next two years in Iowa and South Dakota, they're both in the top six of states with the lowest expected increase.

Iowa's projected increase of 10.6 percent is the fifth lowest. South Dakota is next at 11.1 percent.


  • North Dakota: +6.7%
  • Missouri: 8.3%
  • Wisconsin: +8.3%
  • New Jersey: +10.5%
  • Iowa: +10.6%
  • South Dakota: +11.1%
  • New York: +12.2%
  • Rhode Island: +12.5%
  • Kansas: +12.7%
  • West Virginia: +12.8%

The outlook in Minnesota isn't so good.

The projected increase in the state is 21.2 percent, which is the 18th highest in America.

Four states are expected to see an expansion of more than 30 percent by 2025.


  • Arizona: +33.3%
  • Vermont: +30.8%
  • Nevada: +30.6%
  • Wyoming: +30.0%
  • Alaska: +29.4%
  • Virginia: +26.7%
  • Georgia: +26.7%
  • South Carolina: +26.3%
