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.

有边缘性人格障碍的成年人和青少年的症状障碍。

症状性疾病通常与边缘性人格障碍（BPD）并发。这项研究的目的是比较成人和青少年BPD住院患者报告的合并症发生率，包括复杂合并症（即情感和冲动性疾病的组合）。使用年龄适合的半结构式访谈对一百四十四名BPD的青少年（13-17岁）和290名成年人（18-35岁）进行了访谈，以评估症状性疾病。两个研究组的情绪障碍和ADHD的终生发生率非常相似。然而，成年人的焦虑症（包括PTSD，药物滥用，饮食失调和复杂合并症）的发生率明显高于青少年。在一起 这项研究的结果表明，与BPD青少年相比，在成年人中广泛定义的情感障碍和冲动障碍更为普​​遍。他们还建议，对于这两组边缘患者，复杂合并症的模式甚至更加明显。
