In Nicholas Carr’s clarion call about the Internet, he says psychological research has proved that “frequent interruptions scatter our thoughts, weaken our memory and make us tense and anxious.” (The Shallows 2011, p. 132) He then points out that we “ask the Internet to keep interrupting us in ever more and different ways.” (Carr, p. 134)
One parallel development during the same time frame as the rise of the Internet has been the rise in antidepressant use in the US. According to a 2011 report from the Centers for Disease Control and Prevention (CDC), antidepressant use has soared 400% in the past 20 years:
Eleven percent of Americans ages 12 years and older took antidepressants during the 2005-08 study period, the authors write. They add that though the majority of antidepressants were taken to treat depression, the drugs also can be used for anxiety disorders and other conditions.

According to a government study, antidepressants have become the most commonly prescribed drugs in the United States. In its study, the U.S. Centers for Disease Control and Prevention looked at 2.4 billion drugs prescribed in visits to doctors and hospitals in 2005. Of those, 118 million were for antidepressants.

To date, no U.S. study has causally linked anxiety and depression with use of the internet. Even these articles consider other possibilities for the huge increase in antidepressant use, such as the economy, job loss and pharmaceutical advertising. However, as emerging data describe increasing pressure from technology, can we make the leap and consider that the internet materially contributes to the problem?
