Which mood stabilizer is most associated with reducing suicide risk?

• A. Lithium
• B. Valproate
• C. Lamotrigine
• D. Carbamazepine

Answer: (A)

The main idea is that lithium has a unique anti-suicidal effect among mood stabilizers. A large body of clinical data shows that lithium lowers suicide risk in mood disorders, especially bipolar disorder, with fewer completed suicides and fewer attempts in patients treated with lithium compared to those not on it. This anti-suicidal benefit appears to go beyond simply stabilizing mood and may relate to reducing impulsivity and aggression, plus possible neuroprotective effects. Other mood stabilizers effectively control manic and depressive symptoms but do not have as consistent evidence for reducing suicide risk. Valproate is valued for rapid mood stabilization in mania but lacks strong data on suicidality reduction. Lamotrigine helps with bipolar depression and has some signals for suicidality, but the strongest, most replicated anti-suicidal effect comes from lithium. Carbamazepine also lacks robust evidence for lowering suicide risk and carries notable side effects and interactions.
