You wouldn't necessarily place video games and medical devices in the same sentence. But a Boston and San Francisco-based startup--the year-old Akili Interactive Labs--has formed with the idea of using video games as cognitive therapy. And as Xconomy's Luke Timmerman reports, Akili envisions submitting its game for FDA approval as a medical device, perhaps within a few years. Boston-based PureTech Ventures launched the company, according to the report, based in part on research by Adam Gazzaley at the University of California-San Francisco that focused on how multitasking affects productivity. Some game developers from George Lucas' video game company LucasArts also joined the company and have already developed a prototype game. Story
