Latent Toxoplasmosis in Females With Borderline Personality Disorder

Plain-language summary

Borderline personality disorder is a common mental disorder with core features of affective dysregulation, impulsivity, and identity disturbance. Although this disorder is mostly understood as a result of a combination of biological factors (genes, temperament) and early aversive experiences (often of traumatic nature), recent data suggest that other factors may be important in its development and course. Preliminary findings show that patients with borderline personality disorder have higher prevalence of Toxoplasma seropositivity. This infection may manifest in symptoms such as affective dysregulation, aggression, suicidality, or anxiousness. As such, it may play a role in the psychopathology of the borderline personality disorder. The aim of this study is to explore the prevalence of Toxoplasma seropositivity in a sample of females with borderline personality disorder, its clinical correlates, and a potential impact on outcomes of an intensive six-week inpatient schema-therapeutic treatment. Results may enrich our understanding of this disorder and lead to improvements of the therapeutic approaches.
