Questions about the Internet’s deleterious effects on the mind are at least as old as hyperlinks. But even among Web skeptics, the idea that a new technology might influence how we think and feel—let alone contribute to a great American crack-up—was considered silly and naive, like waving a cane at electric light or blaming the television for kids these days. Instead, the Internet was seen as just another medium, a delivery system, not a diabolical machine. It made people happier and more productive. And where was the proof otherwise?

Now, however, the proof is starting to pile up. The first good, peer-reviewed research is emerging, and the picture is much gloomier than the trumpet blasts of Web utopians have allowed. The current incarnation of the Internet—portable, social, accelerated, and all-pervasive—may be making us not just dumber or lonelier but more depressed and anxious, prone to obsessive-compulsive and attention-deficit disorders, even outright psychotic. Our digitized minds can scan like those of drug addicts, and normal people are breaking down in sad and seemingly new ways.

…Does the Internet make us crazy? Not the technology itself or the content, no. But a Newsweek review of findings from more than a dozen countries finds the answers pointing in a similar direction. Peter Whybrow, the director of the Semel Institute for Neuroscience and Human Behavior at UCLA, argues that “the computer is like electronic cocaine,” fueling cycles of mania followed by depressive stretches. The Internet “leads to behavior that people are conscious is not in their best interest and does leave them anxious and does make them act compulsively,” says Nicholas Carr, whose book The Shallows, about the Web’s effect on cognition, was nominated for a Pulitzer Prize. It “fosters our obsessions, dependence, and stress reactions,” adds Larry Rosen, a California psychologist who has researched the Net’s effect for decades. It “encourages—and even promotes—insanity.”

Strident fearmongering, brain scans, dopamine, Nicholas Carr; this article is your one-stop shop for all your Zombie Internet Eatin Mah Brainz! needs. And yes, we can now file computers alongside fatty foods, make-up sex, and sugar in the list of Things That Affect Your Brain Like Cocaine. Maybe, given a little more time and some more fMRI analysis, the Internet can even graduate to being the new heroin.
