Borderline Personality Disorder (BPD) is classified in the DSM-5 as a personality disorder marked by pervasive instability in interpersonal relationships, self-image, and affect, alongside marked impulsivity. The diagnostic criteria require five or more of the following nine symptoms: frantic efforts to avoid abandonment (real or imagined), unstable interpersonal relationships, identity disturbance, impulsive behaviors that are potentially self-damaging, recurrent suicidal behavior or self-harm, affective instability, chronic feelings of emptiness, intense or inappropriate anger, and transient, stress-related paranoia or dissociation. This framework is widely used by clinicians to identify BPD and differentiate it from other disorders, guiding treatment plans that may include 📝Dialectical Behavior Therapy (DBT), medication, and support networks.
