'Stupid' Virus Discovered

Virus that 'makes humans more stupid' discovered

A virus that infects human brains and makes us more stupid has been discovered, according to scientists in the US.

The algae virus, never before observed in healthy people, was found to affect cognitive functions including visual processing and spatial awareness.

Scientists at Johns Hopkins Medical School and the University of Nebraska stumbled upon the discovery when they were undertaking an unrelated study into throat microbes.

Of the 90 participants in the study, 40 tested positive for the algae virus. Those who tested positive performed worse on tests designed to measure the speed and accuracy of visual processing. They also achieved lower scores in tasks designed to measure attention.

Humans’ bodies contain trillions of bacteria, viruses and fungi. Most are harmless, but the findings of this research show that there some microbes can have a detrimental impact on cognitive functions, while leaving individuals healthy.

The study’s findings were published in the Proceedings of the National Academy of Sciences.
