Symptomatic disorders often co-occur with borderline personality disorder (BPD). This study's purpose was to compare the rates of comorbidity reported by adult and adolescent inpatients with BPD, including complex comorbidity (i.e., a combination of disorders of affect and impulsivity). One hundred four adolescents (aged 13-17) and 290 adults (aged 18-35) with BPD were interviewed using an age-appropriate semistructured interview for the assessment of symptomatic disorders. Lifetime rates of mood disorders and ADHD were quite similar for the two study groups. However, rates of anxiety disorders, including PTSD, substance use disorders, eating disorders, and complex comorbidity were significantly higher among adults than adolescents. Taken together, the results of this study suggest that broadly defined disorders of both affect and impulsivity are more common among adults than adolescents with BPD. They also suggest that a pattern of complex comorbidity is even more distinguishing for these two groups of borderline patients.

患有边缘性人格障碍的成人和青少年的症状性障碍。

症状性障碍通常与边缘型人格障碍（BPD）同时发生。本研究的目的是比较成年和青少年 BPD 住院患者报告的合并症发生率，包括复杂合并症（即情感障碍和冲动障碍的组合）。104 名患有 BPD 的青少年（13-17 岁）和 290 名成人（18-35 岁）接受了与年龄相适应的半结构化访谈，以评估症状性疾病。两个研究组的情绪障碍和多动症的终生发生率非常相似。然而，焦虑症的发生率，包括 PTSD、物质使用障碍、饮食障碍和复杂的合并症，在成年人中显着高于青少年。综合起来，这项研究的结果表明，与患有 BPD 的青少年相比，成年人中广泛定义的情感和冲动障碍更为常见。他们还表明，对于这两组边缘患者来说，复杂的合并症模式更加明显。
