DSM-5 diagnostic criteria for borderline personality disorder
A pervasive pattern of instability of interpersonal relationships, of self-image, and affects as well as marked impulsivity beginning by early adulthood and present in a variety of contexts as indicated by 5 or more of the following:
- Frantic efforts to avoid real/imagined abandonment (suicidal or self-mutilating behavior not covered in criterion)

- Identity disturbance: Markedly and persistently unstable self-image or sense of self
- Impulsivity in at least 2 areas that are potentially self-damaging, for example, spending, substance abuse, reckless driving, sex, binge eating, etc. (suicidal or self-mutilating behavior not covered in criterion)
- Affective instability caused by a marked reactivity of mood, for example, intense episodic dysphoria, anxiety, or irritability, usually lasting a few hours and rarely more than a few days.
- Chronic feelings of emptiness
- Inappropriate, intense anger, or difficulty controlling anger, for example, frequent displays of temper, constant anger, recurrent physical fights.
- Transient paranoid ideation or severe dissociative symptoms
Psychiatric comorbidities:
BPD is often a comorbid condition of other psychiatric disorders (formerly conceptualized as axis-I disorders according to DSM-IV), foremost depression, other personality disorders, and there seems to be syndromal overlap and/or comorbidity with bipolar disorder (BD), attention deficit/hyperactivity disorder (ADHD) and posttraumatic stress disorder (PTSD)

- Substance abuse disorders (64%)
- Eating disorders (53%)
- Attention deficit hyperactivity disorder (ADHD) (10-30%)

Diagnosis
Clinical assessment:
Several diagnostic instruments are available to aid in diagnosis.
- McClean Screening Instrument for BPD
- Personality Diagnostic Questionnaire
- Structured Clinical Interview for DSM-5 Personality Disorders
- Minnesota Borderline Personality Disorder Scale
- Personality Assessment Inventory-Borderline Features Scale
Management
Psychotherapies:
These therapies provide active and focused interventions that emphasize current functioning and relationships. These therapy modalities also provide; (a) a structured manual that supports the therapist and provides recommendations for common clinical problems; (b) they are structured so that they encourage increased activity, proactivity, and self-agency for the patients; (c) focus on emotional processing, particularly on creating robust connections between acts and feelings; (d) increased cognitive coherence in relation to subjective experience in the early phase of treatment by including a model of pathology that is carefully explained to the patient, and encouraging an active stance by the therapist, which invariably includes an explicit intent to validate and demonstrate empathy and generate strong attachment relationships to create a foundation of alliance.
- Mentalizing-based therapy (MBT): Helps patients manage emotion dysregulation by feeling understood, allowing them to be more curious and make fewer assumptions about the intentions of the people around them.
- Dialectical behavior therapy (DBT): Combines mindfulness practices with concrete interpersonal and emotion regulation skills.
- MBT and DBT each incorporate individual and group treatment over 12 to 18 months
- Transference-focused psychotherapy (TFP): Focuses on using patient-therapist relationship to develop the patient’s awareness of problematic interpersonal dynamics
- Cognitive-behavioral therapy (CBT)
- Schema-focused therapy
- Family therapy (for adolescents): Appropriate substitute for group therapy, though not always.
Pharmacotherapy:
- Antipsychotics
- Anti-depressants: SSRIs, TCAs
- Mood-stabilizing drugs
