More than 5 million Americans are currently living with Alzheimer's disease, and the National Institute on Aging estimates that that number is going to triple by 2050 — in part due to aging baby boomers.

The cost of coping with the disease — currently estimated at $215 billion — is projected to rise to half a trillion dollars by 2050. That amount will likely tax our overburdened health care system, the economy and the families of those affected.

Amy Goyer realized her 84-year-old father Robert's health was deteriorating one night while watching a movie with him.

When the American Psychiatric Association releases its new Diagnostic and Statistical Manual of Mental Disorders -- DSM-5 -- this weekend, lots of journalists and commentators will refer to it as "psychiatry's bible."

That's a term that makes the manual's authors and other mental experts cringe.

To curb drunken driving, the federal National Transportation Safety Board has voted to recommend that states tighten the legal limit for drivers' blood alcohol.

The threshold now for drunken driving is a blood alcohol concentration of 0.08. (The BAC equals alcohol divided by the volume of blood it's in.)

The NTSB would push for it to be lowered to 0.05, in line with the limits in countries such as Denmark, the Philippines and Switzerland.

A study of genetically identical mice is providing some hints about humans. How can one identical twin be a wallflower while the other is the life of the party?

The study of 40 young mice found that their behavior grew increasingly different over three months, even though the mice shared the same genes and lived in the same five-level cage, researchers report Thursday in the journal Science.

Less than two weeks after launching its Alert Energy Caffeine Gum, the Wrigley Company decided that maybe the world wasn't ready for amped-up chewing gum after all.

On April 30, the day after Alert Energy launched, the Food and Drug Administration said it was going to take a "fresh look" at caffeinated foods, particularly their effect on children and teenagers.

Being out front on caffeinated confections evidently wasn't a comfortable place to be.

Age-related macular degeneration is the major cause of blindness in older people, and the culprit in more than half of all cases of blindness in the United States.

There's no cure for the condition, so scientists have been hard at work trying to come up with ways to hold it at bay.

Economists think prices are close to magic — constantly changing signals that help people figure out what to buy and who to buy it from (and what to sell and who to sell it to).

But in health care, it seems like nobody knows the price of anything. This recent study, for example, found most hospitals can't provide an up-front price estimate for a hip replacement.

I'm Robert Siegel. And we start this hour with health care - what it costs hospitals, what it costs the government and how states are moving to expand coverage for the poor. We'll begin with the news that the Obama administration today released the first ever national data on what hospitals actually charge for Medicare patients.

When the House Committee on Veterans' Affairs held a hearing recently, members expressed concern that veterans might not qualify for subsidies for the new health insurance marketplaces if they were enrolled in VA health coverage.
