The center, called ReSTART, is somewhat ironically located near Redmond, headquarters of Microsoft and a world center of the computer industry. It opened in July and for $14,000 offers a 45-day program intended to help people wean themselves from pathological computer use, which can include obsessive use of video games, texting, Facebook, eBay, Twitter and any other time-killers brought courtesy of technology.

"We've been doing this for years on an outpatient basis," said Hilarie Cash, a therapist and executive director of the center. "Up until now, we had no place to send them."

Internet addiction is not recognized as a separate disorder by the American Psychiatric Association, and treatment is not generally covered by insurance. But there are many such treatment centers in China, South Korea and Taiwan — where Internet addiction is taken very seriously — and many psychiatric experts say it is clear that Internet addiction is real and harmful.
