Swedish researchers studied more than seven thousand people with Alzheimer's disease.
They found those taking drugs like Aricept, Exelon, or Razadyne were a third less likely to die from any cause -- compared to people not taking the drugs.
They also had a nearly forty percent reduced risk for heart attack.
The researchers can't say the drugs caused these benefits -- but they believe there is a link.
