Red flags
- Late-onset personality change with cognitive, neurological or systemic red flags — investigate organic disease before locking a personality diagnosis
- Acute suicidal intent, plan, high-lethality attempt, or severe aggression — medical stabilisation and dynamic risk formulation first, independent of trait labels
- Using 'personality disorder' pejoratively to withhold care, crisis planning, or treatable comorbidity work-up
- Missing bipolar mania/hypomania, PTSD/complex PTSD, ADHD, autism, or substance intoxication/withdrawal while attributing everything to traits
- Chronic unreviewed polypharmacy framed as treatment of personality disorder itself
- Confusing personality difficulty with full personality disorder, or equating any interpersonal conflict with severe PD
Meet the patient
The handover runs: "She's got borderline, plus avoidant, plus dependent traits, and probably a bit of narcissistic. Four personality disorders. Nothing much we can do." Three clinicians nod. Nobody has said how impaired she is.[1][14]
She is 29. She has had four crisis presentations this year, cannot hold a job past three months, has one friendship she alternately idealises and cuts off, and describes herself as "nothing, really" when asked who she is.[8][17]
Four labels have been stacked and not one of them tells you what to do on Monday. The whole point of ICD-11 is that the second paragraph — not the first — is the diagnosis.[1][3][8]
