Abstract
Suicide and suicidal behaviors are complex, heterogeneous phenomena that are thought to result from the interactions among distal factors increasing predisposition and proximal factors acting as precipitants. Epigenetic factors are likely to act both distally and proximally. Aspirational Goal 1 aims to find clear targets for suicide and suicidal behavior intervention through greater understanding of the interplay among the biological, psychological, and social risk and protective factors associated with suicide. This paper discusses Aspirational Goal 1, focusing on the research pathway related to epigenetics, suicide, and suicidal behaviors. Current knowledge on epigenetic factors associated with suicide and suicidal behaviors is reviewed and avenues for future research are discussed. Epigenetic factors are a promising area of further investigation in the understanding of suicide and suicidal behaviors and may hold clues to identifying targets or avenues for intervention.
