The Aging Brain Is Less Quick, But More Shrewd

or baby-boomers, there is both good news and bad news about the cognitive health of the aging brain.

Brain researcher Gary Small from UCLA conveys the bad news first: "Reaction time is slower," he says. "It takes us longer to learn new information. Sometimes it takes us longer to retrieve information, so we have that tip-of-the-tongue phenomenon — where you almost have that word or that thought. That's typical of the middle-age brain."

As we age, our ability to multi-task diminishes. "We're quick, but we're sloppy when we're in middle-age. We make more errors when we're in middle age," says Small.
