Abstract:
Introduction: Oxidative stress plays a critical role in the pathogenesis of neurodegenerative and neuropsychiatric disorders. However, its role in suicidal behavior has not been clarified yet. Consequently, we aimed to evaluate the oxidant-antioxidant status in the serum of suicide attempters in Ilam city.
Methods: Fifty suicide attempters and 40 control subjects (volunteers) aged 18-35 years were studied in the current experiment. To consider the oxidant-antioxidant status, serum levels of Malondialdehyde (MDA), Nitric Oxide (NO), Superoxide Dismutase (SOD), and the Total Antioxidant Capacity (TAC) were measured.
Results: Serum levels of SOD and TAC were significantly lower in the suicide attempters group compared to the controls. Furthermore, serum NO level was significantly higher in the suicide attempters compared to the control groups. Interestingly, the serum level of MDA was significantly lower in the suicide attempters compared to the control groups.
Conclusion: The oxidative stress without MDA elevation, detected in suicide attempters, can be considered a biochemical hallmark in suicide behavior.

● Oxidative and nitrosative stress may play role in the pathogenosis of suicidal behavior.
● MDA level decreases in people with risk of suicide.
● Oxidative stress occurs when there is an imbalance between free radical generation and antioxidant capacity.
Plain Language Summary
Suicide is a complex behavior and different factors, including environmental factors, social facilities, health and supportive systems. Increasing antioxidant content of daily diet may be used as a strategy to decrease suicidal behavior in high risk people. Oxidative stress occurs when there is an imbalance between free radical generation and antioxidant capacity. Oxidative stress plays a role in the aging and pathogenesis of neurodegenerative diseases, like Alzheimer’s disease, Huntington’s disease, and Parkinson’s disease. This study aimed to investigate the correlation between oxidant-antioxidant levels and suicidal behavior.
