Suicidal behaviour in bipolar disorder: risk and prevention

Area of Science:

• Psychiatry
• Clinical Psychology
• Neuroscience

Background:

• Bipolar disorder is a severe mental illness with a high risk of premature mortality, primarily due to suicide.
• Suicide rates in individuals with bipolar disorder are over 20 times higher than in the general population.
• Suicidal acts are often linked to severe depressive or mixed episodes early in the illness course.

Purpose of the Study:

• To review the lethality of bipolar disorder, focusing on suicide risk.
• To assess current and potential interventions for managing suicidality in bipolar disorder.
• To highlight the need for research into novel treatments' impact on overall mortality.

Main Methods:

• Systematic review of existing literature on bipolar disorder, suicide, and treatment efficacy.
• Analysis of risk and protective factors for suicide in bipolar patients.
• Evaluation of evidence for various short-term and long-term therapeutic interventions.

Main Results:

• Lithium maintenance treatment is strongly evidenced to reduce suicidal risk in bipolar disorder.
• Many other treatments (antidepressants, antimanics, etc.) have limited evidence for reducing mortality.
• Close clinical supervision and rapid hospitalization are key short-term interventions for acute suicidality.

Conclusions:

• While lithium is effective, further research is needed on newer drugs' ability to reduce suicide and other mortality risks.
• Systematic application of current knowledge and sustained patient follow-up can improve outcomes.
• Addressing the high mortality associated with bipolar disorder requires a comprehensive approach to treatment and risk management.
