The world's population is graying, and as a result, nations around the globe are staring down a rising tide of people who will grapple with the ravages of Alzheimer's disease and other dementias. According to a new report from Alzheimer's Disease International, some 35.6 million people worldwide will have a form of dementia in 2010. That number is expected to nearly double every 20 years, reaching an estimated 65.7 million in 2030 and 115.4 million in 2050.
Undoubtedly, adult children navigating the emotional and logistical maze of caring for a parent with dementia wonder, "Will this be my fate, too?" Even those without familial ties to a person with the disease fear its hallmark memory loss, confusion and relinquishing of independence.
