Adult attention deficit hyperactivity disorder (ADHD) is often associated with personality pathology. However, only few studies have been conducted on the link between ADHD and pathological narcissism (PN), with or without a diagnosis of narcissistic personality disorder (NPD). In order to fill this gap, PN and NPD were assessed in 164 subjects suffering from ADHD, with several other measures including ADHD severity, quality of life, depression, anxiety, impulsivity, and emotion dysregulation (ED). We found that a significant proportion of ADHD patients suffered from NPD, and that both narcissistic grandiosity and vulnerability were associated with ADHD hyperactivity and impulsivity symptoms, but not with inattentive symptoms. These two dimensions seemed to be negatively associated with well-being and positively associated with most of the other studied psychiatric dimensions except ED, the latter being only associated with vulnerability, even after adjustment on borderline symptoms. Overall, despite important limitations that limit the generalizability of our findings to the overall ADHD population (notably linked to selection bias), we believe that this exploratory study sheds light on the potential clinical relevance of narcissistic pathology in adult ADHD patients.

成人多动症和病理性自恋：回顾性分析


成人注意力缺陷多动障碍（ADHD）通常与人格病理有关。然而，无论是否诊断出自恋型人格障碍（NPD），关于 ADHD 和病理性自恋（PN）之间的联系的研究很少。为了填补这一空白，我们对 164 名 ADHD 受试者进行了 PN 和 NPD 评估，并采用了其他一些指标，包括 ADHD 严重程度、生活质量、抑郁、焦虑、冲动和情绪失调 (ED)。我们发现，很大一部分 ADHD 患者患有 NPD，自恋自大和脆弱都与 ADHD 多动和冲动症状相关，但与注意力不集中症状无关。这两个维度似乎与幸福感呈负相关，与除 ED 之外的大多数其他研究的精神维度呈正相关，后者仅与脆弱性相关，即使在对边缘症状进行调整后也是如此。总的来说，尽管有重要的局限性限制了我们的研究结果对整个 ADHD 人群的普遍性（特别是与选择偏差有关），但我们相信这项探索性研究揭示了成年 ADHD 患者自恋病理学的潜在临床相关性。
