The schizophrenia is a little unknown mental illness and mysterious, since yet is not known very well from where proceeds. The exact causes of schizophrenia are unknown, although most experts point to a “limited supply” is responsible. In this sense, the idea is that each person has a number of more or less noticeable handicaps for the development of life, and indeed, in certain situations, not all react the same (whether biological or mental level). For example, before a tragic incident for the individual depends on the percentage that comes standard in each of us to develop this disease or not.

Thus, it can happen that someone with a high level of vulnerability to the disease, the loss of a job can be sufficient to develop schizophrenia. Of course, this does not explain the cause of schizophrenia as such, because we have to take into account biological factors.

Among the biological factors to consider include the genes. If there is a case of schizophrenia in the family, a descendant of the same is more likely to develop than any other. However, not known for certain what genes are involved or how do to run this disease.

Dopamine is another factor to consider. It is a neurotransmitter and is one of the many chemicals in the brain. As reflected by the specialists, this substance is directly related to the development of schizophrenia. Dopamine is a partner with the feelings of pleasure and reward. The role of dopamine in schizophrenia is based on the fact that drugs that reduce dopamine in the brain also reduce some symptoms of schizophrenia. The development may also influence schizophrenia.

This theory says that while it is forming a brain and is attacked by infection levels increase vulnerability. For example, infections that can have a pregnant woman while directly affecting the development of schizophrenia.
