Blood Test Will Prevent Thousands Of Suicides
Researchers from Johns Hopkins University in Baltimore found: particular gene is responsible for a suicide risk. When this gene, SKA2, ceases to function normally, a person may be tempted to commit suicide. They developed a special test, the results of which will be to predict whether a person will make a suicide attempt.
SKA2 is located in the prefrontal cortex. This gene controls impulsive behavior and prevents negative thoughts. It is responsible for the level of cortisol - a stress hormone. If the amount of this gene in the brain is insufficient or it is changed, the level of cortisol rises. Earlier, it was revealed that people who committed suicide or attempted suicide, had too much cortisol in the body.
Blood test developed by scientists with up to 90% accuracy will tell doctors and psychologists who are capable to commit suicide. With 96% accuracy professionals will see whether a person has attempted suicide. It will become possible to restrict access for such people to medicine and other means by which it is possible to commit suicide. It will be clear what patients should not prescribe pills that provoke suicidal thoughts. Researchers also offer to do such an analysis in soldiers before sending them to the hot spots, and upon their return.
