(NWITIMES) — Currently, an estimated 5 million people have Alzheimer’s disease in the United States, yet this number is projected to triple by 2050, according to researchers at Rush University Medical Center.

The study was published Wednesday in the American Academy of Neurology. It serves as an update of Alzheimer’s disease and dementia estimates since the last published findings from 2003 using the 2000 census population, the study reported.

Within the next 40 years, researchers estimate that 13.8 percent of people will develop Alzheimer’s, if preventive action is not taken, the study cited. Prevention is significant for aging adults, especially for baby boomers 65 and older.
