Measuring the Suicide Tendencies
Suicide tendencies are to be measured on the basis of six biomarkers in the blood of people. To a certain extent these chemicals are produced in relatively large quantities in individuals with suicidal tendency.
In particular, a protein that is produced by a gene with the name SAT-1 would have a predictive value when it comes to suicidal tendencies.
That was written by researchers from the University of Indiana in the scientific journal Molecular Psychiatry.
The researchers reached their findings by the blood of nine subjects to be regularly analyzed during the process. With the patients bipolar disorder had occasionally suffer from suicidal tendencies during the study, but in some periods they had no suicidal thoughts.
The scientists found a link between the six biomarkers and the periods in which the subjects had strong suicidal tendencies. Suicidal tendencies make probably stress at the cellular level, allowing production of these specific substances could be reinforced.
Especially the SAT1 gene made more protein if the participants had suicidal thoughts. “This substance was head and shoulders above the rest”, explains lead researcher Alexander Niculescu.
Small study to Measure Suicide Risk with Blood Test
Due to the small number of suitable subjects that scientists could find, there may be no definitive conclusions can be drawn from the study. The correlation found between the biomarkers and suicidal tendencies also is not yet strong enough to use in practice.
Ultimately, the scientists managed to be in by 65 to 80 percent to predict which people from a group of 80 psychiatric patients recover foreseeable future with suicidal symptoms would be included. Security that did the researchers based on both blood levels and other patient information.
According to Niculescu this result suggests that blood tests can be used in the mapping of suicide in psychiatric patients in the future. “Suicide is not only related to mental illness,” he says. “It’s a much more complex type of behavior.”
