10. "Alzheimer's Disease as a Cause of Death in the United States"

Summary: Alzheimer's isn't necessarily the direct cause of death, but also commonly the underlying factor that ultimately perceives death. Also many a time, even if the person does have Alzheimer's, it is not listed on the death certificate whatsoever, which may adjust numbers for those who had passed away from a discerning relation of AD.

Key Facts:
"In 1995, Alzheimer's disease was reported as the underlying cause of 20,606 deaths, with 20,230 of these deaths to people 65 years of age or older. Multiple cause data indicate that in 1995, Alzheimer's disease was listed as one of the causes of death on a total of 41,419 death certificates for all ages and 40,836 for people 65 years of age and older."
"Age-adjusted death rates for AD tended to be greater for states in the Northeast and Northwest than for the United States overall; however, the differential between states diminished somewhat over time."
