[Impulse control and affect regulation in personality disorders]

Area of Science:

• Psychology
• Clinical Psychology
• Neuroscience

Context:

• Investigates the interplay between affect dysregulation and impulse control disorders in borderline personality disorder (BPD) and antisocial personality disorder (ASPD).
• Examines affective responses to experimental stimuli in individuals with BPD and ASPD.
• Highlights the specific stressors, such as fear of abandonment, that trigger intense emotional responses in BPD.

Purpose:

• To differentiate emotional response patterns in borderline personality disorder (BPD) and the psychopathic subtype of antisocial personality disorder (ASPD).
• To explore the relationship between emotional detachment and violent impulses in ASPD.
• To consider the implications of these findings for psychotherapy in BPD.

Summary:

• In BPD, intense emotional reactions are linked to specific stressors like fear of abandonment, rather than generalized hyperreactivity; some female BPD patients exhibit reduced emotional arousal.
• Findings support the emotional detachment theory in psychopathic ASPD, suggesting a lack of fear or compassion may predispose individuals to violence.
• The study contrasts the emotional profiles of BPD and psychopathic ASPD, offering insights into their distinct affective dysregulation and impulse control mechanisms.

Impact:

• Provides a nuanced understanding of emotional dysregulation in BPD, challenging assumptions of universal hyperreactivity.
• Offers empirical support for the role of emotional detachment in the psychopathic subtype of ASPD and its link to aggression.
• Informs the development of targeted psychotherapeutic interventions for BPD by clarifying the role of specific stressors and emotional responses.
