DSM-5-TR diagnostic criteria summary
BPD requires a pervasive pattern of instability of interpersonal relationships, self-image, and affects, and marked impulsivity, with at least 5 of 9 criteria:
- Frantic efforts to avoid real or imagined abandonment.
- Pattern of unstable and intense interpersonal relationships characterized by alternating between extremes of idealization and devaluation.
- Identity disturbance: markedly and persistently unstable self-image or sense of self.
- Impulsivity in at least 2 areas potentially self-damaging (spending, sex, substance use, reckless driving, binge eating).
- Recurrent suicidal behavior, gestures, or threats, or self-mutilating behavior.
- Affective instability due to marked reactivity of mood (intense episodic dysphoria, irritability, or anxiety usually lasting hours, rarely more than a few days).
- Chronic feelings of emptiness.
- Inappropriate, intense anger or difficulty controlling anger.
- Transient, stress-related paranoid ideation or severe dissociative symptoms.

Differential diagnosis
- F31.81 Bipolar II Disorder, discrete hypomanic + depressive episodes (days-to-weeks); BPD affective instability is brief and reactive.
- F33, F32 Major Depressive Disorder, common comorbidity; differential rests on whether mood instability is interpersonal-reactive (BPD) vs episodic (MDD).
- F43.10 Post-Traumatic Stress Disorder, high comorbidity in BPD (often with extensive trauma history); differential important for treatment selection.
- F60.81 Narcissistic Personality Disorder, F60.4 Histrionic PD, F60.7 Dependent PD, overlapping interpersonal patterns; often co-coded.
- F90.0 ADHD, impulsivity and emotional dysregulation overlap; ADHD lacks the identity disturbance and abandonment fears central to BPD.
- F25.x Schizoaffective Disorder, BPD's transient stress-related paranoid ideation is brief and reactive, not psychotic in the sustained sense.
Common comorbidities
BPD has very high lifetime psychiatric comorbidity (~85% of patients meet criteria for at least one other DSM-5-TR diagnosis). Common co-occurring conditions: Major Depressive Disorder (F33, F32, up to 80% lifetime), PTSD (F43.10, up to 60%), Substance Use Disorders (F10–F19), Generalized Anxiety Disorder (F41.1), Bipolar II (F31.81), Eating Disorders (F50.x), and ADHD (F90.x). Routinely co-administer PHQ-9, GAD-7, PCL-5, and AUDIT alongside BPD-specific screening.
