Alzheimer's Disease Burden to Double by 2060
Nearly 14 million Americans may have Alzheimer's disease by then
Over 3% of the population -- nearly 14 million Americans -- may have Alzheimer's disease or related dementias by 2060, according to a new CDC report.The burden of Alzheimer's disease and related dementias, which was 1.6% of the U.S. population in 2014, is projected to double to 3.3% by 2060, reported the CDC's Kevin Matthews, PhD, and and colleagues in Alzheimer's & Dementia.
That translates to a jump from 5 million to 13.9 million Americans affected by the disease.
Hispanic Americans are expected to have the biggest increase due to population growth, but non-Hispanic whites still will have the most Alzheimer's cases, based on population numbers.
The study is the first to forecast Alzheimer's disease by race and ethnicity. It shows "that as the U.S. population increases, the number of people affected by Alzheimer's disease and related dementias will rise, especially among minority populations," CDC Director Robert Redfield, MD, said in a statement.
Currently, Alzheimer's disease is the fifth leading cause of death of Americans age 65 and older, the CDC said. Of people in that age group, African Americans have the highest prevalence of Alzheimer's disease and related dementias at 13.8%, followed by Hispanics at 12.2%, non-Hispanic whites at 10.3%, American Indian and Alaska Natives at 9.1%, and Asian and Pacific Islanders at 8.4%.
By 2060, 3.2 million Hispanics and 2.2 million African Americans are expected to have Alzheimer's disease and related dementias, due in part to longer life spans.
The report also addressed the need to support caregivers of Alzheimer's and dementia patients and the importance of early diagnosis. "Early diagnosis is key to helping people and their families cope with loss of memory, navigate the health care system, and plan for their care in the future," Redfield said.
CDC researchers used population projections from the U.S. Census Bureau and percentages of Medicare fee-for-service beneficiaries 65 and older with Alzheimer's disease and related dementias from the Centers for Medicare & Medicaid Services to estimate the number of people with Alzheimer's by age, sex, race, and ethnicity in 2014 and 2060.
