5. Alaska
> Projected increase in adults 65+ with Alzheimer’s disease, 2020-2025: 29.4% (from 8,500 to 11,000)
> Pct. of population 65+: 11.2% — 2nd lowest (total: 82,583)
> Pct. of 65+ pop. with Alzheimer’s disease: 10.3% — 5th lowest

As of 2020, an estimated 10.3% of Alaska residents 65 and over had Alzheimer’s disease, the nation’s fifth lowest percentage. The number of new cases of the disease in the state is expected to increase by 29.4% by 2025, the fifth highest increase in the country. However, the mortality rate from Alzheimer’s among people of all ages is the second lowest in the U.S, at 18 per 100,000 people.

As a consequence of the rapid growth in Alzheimer’s cases, Medicaid costs of caring for residents with the disease is expected to climb by 44.6%, the highest increase in the country and more than double the U.S. average projected increase of 20.2%.
