Using blood samples taken by the coroner from nine men who had committed suicide, they found six molecular signs, or biomarkers, that they say can identify people at risk of committing suicide. To check whether these biomarkers could predict hospitalizations related to suicide or suicide attempts, the researchers analysed gene-expression data from 42 men with bipolar disorder and 46 men with schizophrenia. When the biomarkers were combined with clinical measures of mood and mental state, the accuracy with which researchers could predict hospitalizations was more than 80% (abstract)."
