New blood test can diagnose mental illness

New blood test can diagnose mental illness

Researchers at the University of Campinas - Unicamp and the Federal University of São Paulo (UNIFESP) have developed a blood test capable of diagnosing two types of mental illness: schizophrenia and bipolar disorder. To do so, a blood test was performed on people with some of the types of disease and others who did not.

With MRI, physicians were able to identify changes in the molecules of patients with the disease compared to who did not have schizophrenia or bipolar disorder. "We call these molecules biomarkers, they are present in one investigated group and are absent in the other, or they are present in different concentrations," says Professor Ljubica Tasic of the Institute of Chemistry (IQ) at Unicamp, one of the main conductors of development of the technology.

Because there is currently a deficiency in diagnosis, since in many cases the symptoms of both diseases resemble, and the finding is given through medical research and psychology, the researchers decided to develop this test

With the success of the studies, in addition to diagnostic accuracy, there would be greater assertiveness in treatment, which differs from one disease to another. One of the main points of this test, which relies on biological analysis of a small amount of collected blood, is efficacy, agility and objectivity. "9" Mental disorders such as schizophrenia and bipolar disorder are a major challenge for the system of health, bringing serious financial consequences for both developed and Brazilian countries.The absence of cure and the limitations of the available treatments are reflections of the limited knowledge that has of the brain and of its molecular and cellular mechanisms that regulate its functions " , reports the teacher.

Who walks a lot by car also needs protection from the sun

The study authors analyzed records of more than 1,000 patients in a particular region of the United States, who were referred to hospitals with suspected skin cancer. They found that people who had spent much of the time driving a car were more likely to develop skin cancer on the left side of their bodies and faces, the side more exposed to sunlight while driving.
