• Analysis of core dynamic features of borderline personality disorder.
• Examination of differential diagnoses, including schizophrenia and affective disorders.
• Review of evidence on antecedents and longitudinal aspects of BPD.

Main Results:

• The boundary between borderline personality disorder and schizophrenia is well-established.

• Subtle diagnostic distinctions are most challenging with other personality disorders.
• Evidence regarding antecedents and longitudinal course supports the diagnostic validity of BPD.

Conclusions:

• Understanding core dynamic features aids in diagnosing borderline personality disorder.
• Differential diagnosis is crucial, with clearer boundaries emerging against schizophrenia and affective disorders.
• Further research on longitudinal aspects strengthens the diagnostic validity of borderline personality disorder.
