Newly-Discovered Virus May Lead to Stupidity

By The Daily alternative

Wait what? Yes, it's true: researchers at the School of Medicine Johns Hopkins and the University of Nebraska have recently discovered a virus living inside the throats of healthy adults, the presence of which is linked to lower scores on tests cognitive

the researchers were not looking for the virus. - just happened upon it while analyzing microbes throat for a different study. During this analysis, they found the ATCV-1 virus in samples throat, a virus previously only seen in green algae.

The study authors wrote, "unexpectedly, DNA sequences homologous to ATCV-1 virus, a virus algae not previously known to infect humans were identified in samples obtained from the oropharynx healthy adults. the presence of ATCV-1 was associated with a modest decrease, but measurable cognitive functioning. "


For the study, 92 participants were recruited. It was found that 44 percent of them carries the ATCV-1 virus. Individuals carrying this virus scored an average of seven to nine points lower on cognitive tests (including those that measure spatial perception, attention and visual processing speed) than people who do not test positive for the virus.

The researchers then tested the effects of this virus even in mice. One group of mice was infected with ATCV-1, while a control group was not. The mice were placed in a maze, and the researchers found that mice that had been infected were slower to notice new entries to the labyrinth, and pays less attention to objects introduced into the maze.

According to the study's leader, Dr. Robert Yolken, "this is a clear example that shows that harmless microorganisms '' that we can affect behavior and cognition. Many physiological differences between people a and person B are encoded in the gene set each inherited from the parents, however, some of these differences are fed by different microorganisms that harbor and the way they interact with our genes. "

still do not know how this virus infects humans. Certainly keep an eye out for new research on ATCV-1. Meanwhile, remember that your first defense against any invading virus or other pathogen is a healthy immune system .
