    Violent suicide attempts, like jumping or hanging, are linked to higher urinary cortisol and lower norepinephrine to epinephrine ratios compared to wrist-slashing. These neuroendocrine markers may help assess suicidal intent.

    Area of Science:

    • Neuroendocrinology
    • Psychiatry
    • Clinical Psychology

    Background:

    • Parasuicide, or attempted suicide, presents a significant public health challenge.
    • Understanding neuroendocrine differences between methods of parasuicide may offer insights into intent and risk.
    • Cortisol and catecholamine levels are implicated in stress response and mood disorders.

    Purpose of the Study:

    • To investigate neuroendocrine differences between patients using violent versus less violent methods of parasuicide.
    • To determine if urinary cortisol and the norepinephrine to epinephrine ratio can differentiate between methods of self-harm.

    Main Methods:

    • A comparative study involving 13 patients who used violent parasuicide methods (jumping, hanging) and 19 patients who used wrist-slashing.

  • Measurement of 24-hour urinary cortisol levels.
  • Measurement of the 24-hour norepinephrine to epinephrine ratio.

    • Main Results:

    • Patients employing violent parasuicide methods exhibited significantly higher 24-hour urinary cortisol levels.
    • A significantly lower 24-hour norepinephrine to epinephrine ratio was observed in the violent parasuicide group.
    • These findings suggest distinct physiological profiles associated with different parasuicide methods.

    Conclusions:

    • Elevated urinary cortisol and a reduced norepinephrine to epinephrine ratio may serve as potential neuroendocrine markers for assessing suicidal intent.
    • These biomarkers, alongside established indicators, could aid clinicians in determining the severity of suicidal intent.
    • Further research is warranted to validate these findings and explore their clinical utility in suicide prevention strategies.
