Suicidal behaviour: genes, environmental stress and temperamental traits

Multiple risk factors have been involved in the risk for suicide and multiple trajectories have been hypothesized leading to suicidal behaviour. Consistent evidence suggests the involvement of heritable factors, as well as a critical role of life stress and early adversity. In the present article we will review the evidence for the involvement of genetic, environmental as well as personality traits in the risk for suicide, together with recent evidence supporting an interaction between these different factors.
