Suicide is the leading cause of death in men under fifty in the United Kingdom. It kills more young people than cancer, road accidents, and heart disease combined. And yet, for decades, suicide research was treated as a subset of depression research, as though understanding depression would automatically explain why some people take their own lives. It does not. The neuroscience of suicide is distinct. It involves specific alterations in serotonergic function, decision-making circuitry, pain processing, and cognitive constriction that are not reducible to the neurobiology of low mood. This article examines the neural signatures of suicidal crisis, the biological factors that distinguish people who think about suicide from people who act on those thoughts, and what the science tells us about the critical window in which intervention can save a life.
