States Where Alzheimer’s Is Soaring

States Where Alzheimer’s Is Soaring

Alzheimer’s disease is a degenerative brain disorder that causes memory loss and impairs speech, behavior, and cognitive functions. The most common risk factor for the disease is age. The vast majority of Americans with Alzheimer’s disease are at least 65 years old. 

The Alzheimer’s Association estimates that 5.8 million Americans 65 and older are living with the disease, as of 2020. As more and more of the baby boomer generation reaches that age, the number of Americans with the disease will increase to a projected 7.1 million people by 2025, an increase of nearly 22%. Yet this growth will not be uniform everywhere. In some states, the number of older people Alzheimer’s disease is projected to grow by less than 10%, while in others it is projected to grow by more than 30%.

To determine the states where Alzheimer’s is soaring, 24/7 Tempo reviewed the projected increase in the number of Americans 65 and older with Alzheimer’s disease between 2020 and 2025 in every state from the Alzheimer’s Association’s Alzheimer’s disease Facts and Figures report. The share of the population that is 65 years or older in each state came from the U.S. Census Bureau’s 2018 American Community Survey. The average retirement income by state also comes from the ACS. The percentage of Americans 65 and older with Alzheimer’s disease was calculated using Alzheimer’s Association data and population data from the ACS.

There are currently no approved medical options to prevent or cure Alzheimer’s disease or even slow its progression. In addition to the health challenges faced by those with the disease, Alzheimer’s care can be incredibly costly. The Alzheimer’s Association projects there will be more than $51.2 billion-worth of Medicaid payments made for Americans 65 and over with Alzheimer’s disease in 2020. Older Americans should consider the cost of long-term care when determining when they are going to retire. In nearly every state, it costs over $1 million to retire. This is what it costs to retire comfortably in every state.

The projected increase in Alzheimer’s disease by state is based on the projected population growth of residents aged 65 and older. Some Americans in this age bracket opt to relocate, moving from colder areas to warmer ones, typically in the southern and western parts of the nation. Many cities in these parts of the country have experienced significant population growth over the past decade, due largely to retirees moving in. These are the cities Americans are flocking to.

> Pct. of population 65+: 13.4% (5th lowest)
> Avg. retirement income: $30,394 (6th highest)

Alzheimer’s disease mostly affects older people, and Colorado is a relatively young state. State residents who are 65 and older comprise just 13.4% of the population, the fifth lowest share, and only 10.3% of them have Alzheimer’s, the second lowest share. The mortality rate is also low, at 29 Alzheimer’s-related deaths per 100,000 people, the eighth lowest in the country. At the current rate, the state’s share of the older population is growing fast, partially because it is relatively small now. The U.S. Census estimates that the 65 and older population will grow by 32.0% until 2030 and will then comprise 21.0% of the state’s total population.

> Pct. of population 65+: 13.6% (6th lowest)
> Avg. retirement income: $32,908 (2nd highest)

California, the most populous state, had 16,627 deaths attributed to Alzheimer’s disease in 2018, more than any other state. About 13.6% of the state’s residents are 65 and older, the sixth lowest share in the country, but 13.0% of them have the disease, the ninth highest such share. The number of people 65 and older with Alzheimer’s is expected to increase by a fifth, from 690,000 in 2020 to 840,000 in 2025. Though the average retirement income in California is the second highest in the U.S., Medicaid spending on Alzheimer’s patients is expected to grow by 24.7% in the next five years, well above the average increase of 20.2% expected nationwide.

> Pct. of population 65+: 16.7% (10th highest – tied)
> Avg. retirement income: $27,705 (17th highest)

Though Oregon is tied for the 10th highest share of residents who are 65 and older, only 10.1% of them have Alzheimer’s, the lowest share among all states. However, the mortality rate is relatively high. In 2018, there were 44.6 Alzheimer’s-related deaths per 100,000 people, higher than the U.S. rate of 37.3 deaths per 100,000 people. In 2017, Alzheimer’s disease was the sixth-leading cause of death among residents of all ages in Oregon, according to the CDC.

> Pct. of population 65+: 17.0% (9th highest)
> Avg. retirement income: $25,769 (23rd highest)

About 26,000 residents 65 and older of New Hampshire are living with Alzheimer’s disease. By 2025, that number is expected to increase by more than a fifth. The condition primarily affects older adults, and the state’s population of 65 and older comprises 17.0% of New Hampshire residents, the ninth highest share of all states. The state’s estimated increase in Medicaid payments for residents by 2025 with the disease is 31.9%, the third highest in the country. The U.S. Census estimates that 26.3% of New Hampshire residents will be 60 and older by 2030, a 40% increase in the share of the older population since 2012.

> Pct. of population 65+: 16.3% (16th highest – tied)
> Avg. retirement income: $29,095 (13th highest)

Both the share of residents 65 and older and the share of older residents with Alzheimer’s in New Mexico are among the highest in the country. There are 43,000 New Mexicans who are 65 and older currently living with Alzheimer’s. By 2025, that number is expected to rise by 23.3% to 53,000. The increase will lead to higher costs related to the care of Alzheimer’s patients. Medicaid spending on state residents 65 and older with the disease or other forms of dementia is expected to rise by 22.9%, slightly more than the U.S. projected average increase of 20.2%.

Utah has 34,000 people living with Alzheimer’s disease. Partially because the state’s population of 65 and over is projected to grow by about 30% by 2030 to almost 17.0% of the population, Alzheimer’s cases in Utah are expected to grow by almost a quarter, a rate of increase trailing just nine other states. The total Medicaid payments for Utah residents aged 65 and older living with the condition are expected to grow by 27.0% between 2020 and 2025, the seventh largest increase in the country, according to Alzheimer’s Association data.

Florida has the largest share of elderly population of all states — nearly one in every five residents are 65 or older. Almost 9.0% of the population is 75 and older, also the largest share of all states. As the state’s older population continues to age, the risk of Alzheimer’s, which increases with age, will also inevitably increase. The number of people with the disease is projected to increase by almost a quarter between 2020 and 2025 from 580,000 to 720,000.

Though the share of Georgia’s population aged 65 and over is relatively low, the proportion of state residents 60 and older is growing faster than any other age group of the population, according to the U.S. Census. By 2030, one in five residents will be 60 or older. The number of people with Alzheimer’s disease in Georgia is projected to increase by 26.7%, more than all but six states, from 150,000 in 2020 to 190,000 in 2025. In 2018, the disease was the fifth-leading cause of death among residents of all ages in the state.

> Avg. retirement income: $32,409 (3rd highest)

Age increases the risk of developing the condition — the risk doubles every five years after 65. That may partially explain why the incidence of Alzheimer’s in Virginia is expected to increase by 26.7% by 2025, a higher rate than in most states and higher than the national projected increase of 22.0%. The state’s share of residents who are 65 and older is expected to increase to 19% by 2030, according to the University of Virginia Weldon Cooper Center for Public Service.

The number of people 65 and older with Alzheimer’s disease in Wyoming will surge by 30.0% by 2025, according to the Alzheimer’s Association. Large expected increases in the condition are sometimes in line with large projected increases in the elderly population. Wyoming’s 65 and older population is projected to increase to almost 140,000, or more than a fifth of the state’s total residents by 2030, according to a report by Wyoming’s Department of Administration and Information. Currently, the 65 and older population in the state composes 15.1% of the state’s population.

> Avg. retirement income: $22,382 (6th lowest)

Vermont’s residents who are 65 years of age or older make up 18.2% of the state’s population, the fourth highest share among all states. The expected large increase in the number of people 65 and older with Alzheimer’s in Vermont may be partially due to the large portion of people who are older than 75 in the state, accounting for 7.2% of residents, the ninth highest such share. The risk of Alzheimer’s increases significantly with age.

> Pct. of population 65+: 16.7% (10th highest – tied)
> Avg. retirement income: $26,902 (19th highest)

Nearly 17.0% of Arizona’s population is over the age of 65, and 12.9% of them have Alzheimer’s. The number of older adults with the condition is expected to increase by a third in the next five years, more than any other state. This may in part be due to the fact that Arizona has one of the highest shares of people older than 65. The risk of developing the disease increases with age. In 2018, Alzheimer’s disease was the fifth-leading cause of death in Arizona among state residents of all ages.
