Insecure attachment and the inability to identify emotions are seen as possible explanations for dysfunction of the emotional system in borderline personality disorder. There is a strong association between Borderline personality disorder and insecure attachment, and the attachment types that are most characteristic of these subjects are unresolved, preoccupied, and fearful. Previous studies have demonstrated that insecure attachment patterns, a trait disposition toward negative affect and impulsivity are associated with borderline personality disorder features.

This review aims to identify the relationship between attachment pattern during childhood and the development of borderline personality disorder in adulthood.

The high prevalence and severity of insecure attachments found in these subjects support the central role of disturbed interpersonal relationships in clinical theories of Borderline Personality disorder.
