Societal costs of Borderline Personality Disorders: a matched-controlled nationwide study of patients and spouses.

Patients with BPD differed substantially from the general population with respect to all included costs. The study documented a significant burden on their spouses. Besides the early onset of BPD, which implies that patients are affected before they finish school and enter labor market, the neurocognitive impairment and fundamental symptoms of BPD, e.g. unstable, intense relationships, impulsivity, and lack of stable sense of self together with psychiatric and somatic comorbidity are part of explanation of the excess costs of BPD.
