Depression can be caused by infection

Depression is a disease of the nervous system, however caused, it can be not only stress, fatigue or other, more serious mental disorders. Turhan canli from the University of stony brook suggests, in some cases, depression is caused by infection.

In the brain of patients with depression are sometimes found markers of the inflammatory process, indicating the sensitivity of the organism to certain bacterial or viral agents.

In the example of the parasite Toxoplasma gondii. Toxoplasma inhabits the gastrointestinal tract of cats. When the eggs Toxoplasma from cats are passed to the rat, rodent develop problems with the nervous system, changing sexual behavior. Note, one third of the population of our planet - carriers of Toxoplasma gondii. The influence of the parasite on the human psyche so far has not been studied.

Infectious nature of depression has the right to life. There is still no clear understanding of genetic predisposition to the disease. More research is needed to understand the mechanisms of disease development. Turhan canli insists on conducting a global survey of patients with depression. If the theory of the scientist confirmed, the next step will be to develop a vaccine against depression.
