Disturbing Study Details Parasites Growing in the Human Brain Decreasing Cognitive Function

Not only are parasites a public health concern, but also they take an untold toll on human intelligence. Researchers at Johns Hopkins found ACTV-1, a chlorovirus, in two out of every five subjects. Normally found in algae, the pathogen somehow made a rapid evolutionary leap from infecting plant matter to humans and the cost was diminished cognition in those participants who were infected. According to The American Scholar, “When compared with those who did not harbor the virus, those infected were about 10 percent slower to make calculations and had a reduced attention span, suggesting that the virus compromised their ability to calculate, to focus, and to process visual information — disadvantages in the classroom, on the job, and in other familiar learning situations.”

These findings are disturbing on many levels and further reinforce the need for greater access to health care, especially for the nation’s poorest. If parasites aren’t reined in effectively, they not only threaten public health, but also could reduce human capital.
