Models show that the number of Alzheimer's patients will more than double in 40 years, and costs associated with their care will nearly quintuple
As baby boomers reach their sunset years, shifting nationwide demographics with them, the financial burden of Alzheimer's disease on the United States will skyrocket from $307 billion annually to $1.5 trillion, USC researchers announced today.
Health policy researchers at the USC Leonard D. Schaeffer Center for Health Policy and Economics used models that incorporate trends in health, health care costs, education and demographics to explore the future impact of one of humanity's costliest diseases on the nation's population.
Other key findings include:
"Alzheimer's disease is a progressive disease with symptoms that gradually worsen over time. People don't get better," said Julie Zissimopoulos, lead author of the study and an assistant professor at the USC Price School of Public Policy. "It is so expensive because individuals with Alzheimer's disease need extensive help with daily activities provided by paid caregivers or by family members who may be taking time off of work to care for them, which has a double impact on the economy," she said.
"In late stages of the disease," she added, "they need help with personal care and lose the ability to control movement which requires 24-hour care, most often in an institutional setting."
Zissimopoulos collaborated with Eileen Crimmins of the USC Davis School of Gerontology and Patricia St.Clair of the USC Schaeffer Center on the study, which was posted online ahead of publication by the Forum for Health Economics and Policy on Nov. 4.
The team found that delaying the onset of Alzheimer's even a little can yield major benefits -- both in quality of life and in overall costs.
According to the U.S. Census Bureau, in 2012, 43.1 million Americans were 65 and older, constituting 14 percent of the population. By 2050, that number will more than double to 83.7 million, constituting 21 percent of the population.
Medical advances that delay the onset of Alzheimer's by five years add about 2.7 years of life for patients. By 2050, a five-year delay in onset results in a 41 percent lower prevalence of the disease in the population and lowers the overall costs to society by 40 percent, according to the team's research.
"Our colleagues in the medical field are working on ways to understand how the disease interferes with brain processes -- and then stop it," said Zissimopoulos, who is also an associate director at the USC Schaeffer Center. "Investment in their work now could yield huge benefits down the line."

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
