Question

Quizplus · Accepted Answer

Research suggests that low serotonin levels are associated with an increased risk of suicide, independent of depression. Serotonin is involved in regulating mood, and low levels are linked to impulsivity and aggression, which may contribute to suicidal behavior. High levels of dopamine may also be associated with suicide risk, but the evidence is less clear. Low norepinephrine levels have not been consistently linked to suicide.
