Chicago (AP) A new study finds that a person's risk of developing Alzheimer's disease is increased if both parents had it, too.
And the risk grows as the person gets older.
The study of more than 100 families appears in this month's Archives of Neurology. It shows that more than 20 percent of the adult children of couples with Alzheimer's had the disease
themselves. If the offspring were older than 60, more than 30 Percent were affected. And in those older than 70, more than 40 percent had the illness.
The study's lead author says researchers are working to gauge the magnitude of risk people face.
For now, there's no cure for the more than 26 million people worldwide estimated to have Alzheimer's, which gradually destroys memory and other mental abilities.
