Brain activity to transitional objects in patients with borderline personality disorder.

Area of Science:

• Neuroscience
• Psychology
• Clinical Psychology

Background:

• Adults with borderline personality disorder (BPD) often form attachments to inanimate transitional objects (TOs), such as stuffed animals.
• The neural mechanisms underlying the processing of these attachment-relevant objects in BPD remain largely unexplored.

Purpose of the Study:

• To investigate the neural correlates of processing transitional objects (TOs) in adult patients with borderline personality disorder (BPD).
• To determine the functional significance of these neural responses in relation to attachment anxiety and depressive symptoms.

Main Methods:

• Event-related potential (ERP) recordings were used to measure brain activity.
• Sixteen female BPD patients and 16 matched healthy controls viewed images of their TOs, familiar objects (FOs), and unfamiliar objects (UOs).

Main Results:

• Patients with BPD exhibited a specific increase in frontal P3/Late Positive Potential (LPP) amplitude when viewing their TOs.
• This ERP amplitude increase correlated significantly with attachment anxiety and depression scores in BPD patients.
• Processing of attachment-related TO stimuli specifically modulated emotional stimulus evaluation, reflecting enhanced self-relevance processing in BPD.

Conclusions:

• Transitional objects (TOs) play a significant role in the emotional regulation of individuals with borderline personality disorder (BPD).
• The observed neural responses suggest that TOs help BPD patients cope with attachment anxiety, fear of abandonment, and depressive symptoms.
• These findings highlight the therapeutic potential of transitional objects in managing BPD-related emotional distress.
