A new Swedish study reveals a "remarkably consistent association" between suicide and low levels of the serotonin metabolite 5-HIAA.
Noting that research has linked low serotonin levels and aggression, M. Asberg says that "aggression dyscontrol may partly explain the association between suicide and serotonin." Given the serotonin/suicide connection, Asberg says, measurements of cerebrospinal fluid 5-HIAA levels "may be helpful in the clinical assessment of suicide risk."
