The number of people with Alzheimer’s disease, a degenerative brain disease and the most common form of dementia, will rise by at least 14% in all 50 states over the next eight years. However, the rate of increase will be higher in some states than others, according to a recent report from the Alzheimer’s Association, placing greater financial stress on health care programs and boosting the need for caregivers.

Alaska is projected to have the biggest increase in Alzheimer’s cases, from 7,100 in 2015 to 11,000 in 2017, or a 54.9% jump. Arizona, Nevada, Vermont, and Utah round out the top five with projected increases of at least 40% each. Iowa is expected to have the lowest increase, from 64,000 to 73,000, or 14.1%.

15. California
> Increase in Alzheimer’s, 2017-2025: 33.3%
> Pct. of 65+ pop. with Alzheimer’s: 12.1% (13th highest)
> Population 65+: 13.3% (6th lowest)
> Pct. of 65+ pop. in good health: 74.8% (19th lowest)
> Avg. retirement income: $30,503 (3rd highest)

California, the most populous state, had 12,644 deaths attributed to Alzheimer’s disease in 2014, more than any other state. California has 1.6 million caregivers for Alzheimer’s, the most of any state. The number of people suffering from the disease is expected to climb to 840,000 by 2025, a 33.3% increase.

The average retirement income in California of $30,503 a year is third highest. Still, Medicaid spending on Alzheimer’s patients is expected to grow by 46.8% by 2025, well above the average increase of 37.1% expected nationwide.

24/7 reviewed the Alzheimer’s Association “2017 Alzheimer’s Disease Facts and Figures” report to find for each state the projected percentage increase in the number of people with Alzheimer’s over the next eight years. States in the West and Southeast are expected to have the largest percentage increases in the number of people with Alzheimer’s between 2017 and 2025.
