Brain Games Popular; Experts Remain Skeptical

Max Goldberg recently tried to remember the name of a venture capital firm in California that was mentioned during a business meeting he had attended about a year ago.

While games designed to improve cognition are becoming increasingly popular, most brain experts note the impact of such games on mental ability remains unclear.

There was no reason why Goldberg, 38, should have been able to remember the company. "I hadn't heard the name of the company or even thought about the company in over a year," he said.

But after only about 15 seconds of thinking, Goldberg had his "Aha!" moment: He remembered the company's name.

To most people, the idea of recalling an obscure company name that they hadn't thought of in more than a year seems nearly impossible -- especially for someone older than 30. But Goldberg says he has a secret tool that has aided his memory-recall abilities: He calls it "brain games."

For 10 minutes every morning for the past 40 days, Goldberg has been playing what is called "brain fitness games" on the Web site Lumosity.com. He says the small daily commitment to brain fitness has allowed him to improve vastly his day-to-day memory recall ability.

"I was having memory problems just like everyone else has at my age," Goldberg explained. "Using these games has given me a dramatic improvement in my memory. I'm able to recall names, places and companies that I couldn't remember in the past. And it surprises me I can remember these things and it's given me much greater confidence."

And, according to a recent Associated Press report on "brain fitness" games, Goldberg has plenty of company.

The brain fitness market has boomed in the past few years, growing in revenue by about $125 million between 2005 and 2007, according to a report released this year by SharpBrains, a research and advisory firm.

Web sites, books and computer and video games featuring brain fitness tools and games have spread like wildfire in recent years. Most of the products carry claims that using the brain fitness games can "improve memory and attention," or even "ward off Alzheimer's and dementia." But do they really work?
