2013 Facts & Figures Report Highlights Latest Alzheimer's Numbers
One in nine people who are 65 years of age and older has Alzheimer’s disease. Every 68 seconds, someone who is residing in the United States develops Alzheimer’s disease. By mid-century, that number will drop to every 33 seconds.
These sobering facts are just a few of the many provided in the Alzheimer’s Association’s 2013 Alzheimer’s Disease Facts and Figures. And there are many more. For instance, it’s believed that 5.2 million Americans have Alzheimer’s disease in 2013. Of those, five million are estimated to be 65 years and older. Approximately 200,000 people who are under the age of 65 have early-onset Alzheimer’s. The percentages by age group of people in the U.S. who have Alzheimer’s disease also are interesting: 4 percent are under the age of 65, 13 percent are between the ages of 65-74, 44 percent are between the ages of 75-84, and 38 percent are 85 years of age and above.
Not surprisingly, the prevalence of Alzheimer’s is skewed toward women (who live longer than men). Almost two-thirds of the total Americans who have Alzheimer’s are women. However, the report points out that many studies have not found a significant difference in the development of new cases of any type of dementia based on sex.
Older African-Americans and Hispanics are proportionately more likely than older whites to develop dementia in the United States. The report points out that older African-Americans are about twice as likely to have this condition as older whites. Furthermore, Hispanics are about 1.5 times more likely to have a dementia as older whites. Researcher believes that the increased risk for these two groups is based on the prevalence of health conditions that may increase the risk of Alzheimer’s disease, such as high blood pressure and diabetes.
Additionally, researchers have found that older African-Americans and Hispanics are more likely to have missed diagnoses than older whites. The report points to a recent study of Medicare beneficiaries that found that Alzheimer’s and other types of dementia had been diagnosed in 8.2 percent of white beneficiaries, 11.3 percent of African-American beneficiaries and 12.3 percent of Hispanic beneficiaries. “Although the rates of diagnoses were higher among African-Americans than among whites, this difference was not as great as would be expected based on the estimated differences found in prevalence studies, which are designed to detect all people who have dementia,” the Alzheimer’s Association report states.
So how often does someone develop Alzheimer’s disease? The rate of developing Alzheimer’s disease in one year seems to increase with age. There are approximately 53 new cases per 1,000 people who are between the ages of 65-74. In comparison, 170 new cases have been identified per 1,000 people between the ages of 75-84. Additionally, the average annual incidence of people who are 85 and older is 231 new cases per 1,000 people. Additionally, researchers have found that 65-year-old women who do not have dementia have a one-in-five chance of developing dementia during their lifetime, as compared to 17-percent chance for men. These differences are primarily caused by women’s longer life expectancy.
Researchers also have identified the projected chances by state in the prevalence in Alzheimer’s between 2000 and 2025. The states with the highest percentage change (between 81.1 percent and 127 percent) are Washington, Oregon, Alaska, Idaho, Montana, Wyoming, Nevada, Utah and Colorado. States that are anticipated to have a 49.1 percent to 82 percent increase by 2025 are California, Arizona New Mexico, Texas, Oklahoma, Florida, South Carolina, North Carolina and Virginia. States that are projected to see increases between 31.1 percent and 49 percent in people with Alzheimer’s by 2025 include Hawaii, Nebraska, Louisiana, Arkansas, Alabama, Georgia, Tennessee, Kentucky, Delaware and New Hampshire. Those that are projected to see increases between 24.1 percent and 31 percent in people with dementia during this time period are North Dakota, South Dakota, Minnesota, Wisconsin, Indiana, Ohio, West Virginia, Mississippi, Maryland and Vermont. Finally, the states that are projected to have 24 percent increase or below in people who have Alzheimer’s disease are Kansas, Missouri, Iowa, Illinois, Michigan, New Jersey, Pennsylvania, New York, Connecticut, Massachusetts, Rhode Island and Maine.
I’ll go into more of this report’s findings in future blogs, but wanted to share this information with you because it really provides an overview of the tsunami that faces the United States in relation to this devastating disease.
