Summary
Suicidal ideation is common in bipolar-II depression. Racing thoughts and agitation during depressive episodes are key predictors, suggesting a need for careful assessment and treatment before antidepressant use.
Area of Science:
- Psychiatry
- Clinical Psychology
Background:
- The US FDA issued a warning regarding potential suicidal behavior risks associated with newer antidepressants.
- Suicidal behavior is prevalent in bipolar II (BP-II) depression, particularly in outpatients, often presenting with concurrent hypomanic symptoms (mixed depression).
Purpose of the Study:
- To identify major depressive episode (MDE) and intra-MDE hypomanic symptoms associated with suicidal ideation in BP-II outpatients.
Main Methods:
- A total of 374 consecutive BP-II MDE outpatients were assessed.
- Utilized the Structured Clinical Interview for DSM-IV (SCID), the Hypomania Interview Guide, and the Family History Screen.
Main Results:
- Suicidal ideation was reported by 52.6% of participants.
- Lower Global Assessment of Functioning (GAF) scores, persistent MDE symptoms, and melancholic depression were significantly associated with suicidal ideation.
- Independent predictors of suicidal ideation included decreased self-esteem, racing/crowded thoughts, and psychomotor agitation.
Conclusions:
- Suicidal ideation is linked to depression severity in BP-II disorder.
- Racing/crowded thoughts and psychomotor agitation are significant independent predictors of suicidal ideation.
- Clinicians should assess for these intra-MDE symptoms in BP-II outpatients, as antidepressants may exacerbate them, potentially increasing suicidal behavior risk. Mood stabilizers may be necessary prior to antidepressant initiation.
