Scientists of the Copenhagen University hospital in Denmark found that Toxoplasma gondii Toxoplasma gondii which is a parasite representatives of the family and other mammals, can cause schizophrenia in humans. This publication reports Science Alert.
Toxoplasma gondii belonging to the protist, lives in nerve and muscle tissues and in internal organs, including the brain. This organism causes toxoplasmosis — a disease, usually occurring in the form of light, but becoming dangerous when lowered immunity. The parasite may affect the behavior of its owner — for example, infected rodents disappear fear of cats, increasing the likelihood of being eaten by them, and this, in turn, facilitates the penetration of Toxoplasma into the organism the main host. It is believed that infected people, who make up half the population of the Earth also increases the propensity to risk and anxiety.
Experts analyzed the data obtained in large-scale cohort study of Danish Blood Donor Study with the participation of more than one hundred thousand people. The sample consisted of 80 thousand participants. Scientists have identified 2.5 thousand people with mental disorders and conducted a search of immunoglobulins in their blood that indicates the presence of Toxoplasma and other pathogen — cytomegalovirus, herpes agent.
It turned out that people with Toxoplasma gondii a risk of schizophrenia was nearly 50 percent higher than those at whom the infection was not identified. This relationship became even more obvious when the researchers took into account only those participants who have not suffered from schizophrenia at the time of infection. Despite this new data, scientists believe that evidence of a causal link is premature to speak, although Toxoplasma gondii, probably really is one of the factors in the development of schizophrenia.
