The mood can be influenced by many factors, from financial problems to a fierce discussion with someone, and recent research shows that infections caused by certain bacteria and parasites may be a factor.
According to the Daily Mail, the cause would be that they affect the balance of chemicals in the brain. Here, specifically, what effect it may have some pathogens:
1. Parasite that can make you be more maverick
It is Toxoplasma gondii, a parasite that is found predominantly in the feces of cats, and can influence behavior in some people more senibile. Dr Nicky Boulter, a researcher at the University of Technology Sydney, said that men and women respond differently to infection with Toxoplasma gondii: “Infected men have lower IQs, lower capacity to pay attention, and are more willing not follow the rules and take risks. Women are more friendly and more puzzled. ”
Also, the parasite has been associated with psychiatric illness such as schizophrenia, bipolar disorder or obsessive compulsive disorder. It seems to increase the level of two substances in the brain – dopamine and glutamate, which are related to mood and social interaction.
If they have discovered evidence showing that Toxoplasma gondii is a cause of mental problems, the experts will be able to learn more about how these diseases arise about the mechanisms through which they can be controlled.
2. The bacteria that can make you think faster and better
Researchers investigating the possibility that bacteria called Mycobacterium vaccae to remove prostate cancer found that it may make patients happier and because it can stimulate an area of the brain is involved in the production of serotonin – a substance that gives a good feeling.
For specialists, this discovery was a surprise because, as a rule, infections produce inflammation, and making people feel worse, but somehow this bacterium appears to suppress inflammation, leaving serotonin will take effect. Researchers even hope that these hints will help them develop a new antidepressant drug.
In addition, on Mycobacterium vaccae, which is found naturally in soil and is easily inhaled or taken in hand, he found he could improve the capability of thinking. A study in mice showed that those who were “fed” with this bacterium have gone through a maze two times faster than those who had entered in contact with Mycobacterium vaccae. Experts believe it could have the same effect in humans.
3. Bacteria that can sadden
When you have a more serious infection, such as food poisoning, all you want is to stay in bed to rest and sleep. This constant need for relaxation is the reaction of the body which ensures that all energy can be used to fight infection, the immune system. Interestingly, however, is that a similar behavior and those who are suffering from depression.
39 people have received a small dose of toxin taken from the E. coli bacteria and then were asked to complete a questionnaire. Following their analysis, researchers found that the responses showed two changes in terms of mood: people so they became less interested in rewards, and by interacting with other people.
