Childhood trauma in bipolar affective disorder: A case control study

Area of Science:

• Psychiatry
• Mental Health Research
• Clinical Psychology

Background:

• Bipolar Affective Disorder (BPAD) etiology is complex, potentially involving gene-environment interactions.
• Childhood trauma (CT) is a known risk factor for BPAD and influences its clinical course.
• Detailed investigation into the association of specific CT subtypes with BPAD is lacking.

Purpose of the Study:

• To evaluate the association between childhood trauma (CT) and Bipolar Affective Disorder (BPAD).
• To compare CT prevalence in BPAD patients versus healthy controls.
• To examine the relationship between specific CT subtypes and BPAD.

Main Methods:

• Study included 50 BPAD patients and 50 age/sex-matched healthy controls.
• Childhood Trauma Questionnaire (CTQ) used for CT assessment.
• Statistical analyses applied to compare groups and identify associations.

Main Results:

• A significantly higher prevalence of moderate to severe CT was observed in BPAD patients (76%) compared to controls (20%).
• All subtypes of CT were significantly associated with BPAD.
• Emotional abuse demonstrated the strongest association with BPAD (OR 7.37, CI 1.98-27.31).

Conclusions:

• Childhood trauma is significantly associated with Bipolar Affective Disorder.
• All CT subtypes are linked to BPAD, with emotional abuse having the most substantial impact.
• Further multicentric studies with larger sample sizes are recommended to confirm findings on CT subtypes.
