Cash’s private practice is located in Redmond, Wash. , the home of Microsoft--not an entirely surprising hub of compulsive Internet and video- game use, she says. Indeed, the Seattle--Tacoma area is the nation’s 13th largest media market, and has the highest level of Internet use in the country; according to a recent study, more than 45% of adults in the area regularly play video games. "There ’s nothing wrong with this technology," says Cash, who is careful to note that it’s not the medium that is to blame, but rather, the lack of education about it. "It’s all in how it’s used"
