Narcissistic personality disorder (NPD) and the manic and hypomanic episodes found in the bipolar disorders are characterized by grandiosity. It is possible that this shared grandiosity is a 'homologous structure' or reflects a superficial similarity between two disparate conditions. It is, however, possible that NPD and the bipolar disorders are more closely related than implied by their segregation into the separate superordinate categories of personality disorders and mood disorders. Whereas narcissism is considered to be a life-course, stable trait and the bipolar disorders are characterized by episodes of mania and depression, there is considerable research indicating that narcissism may be linked to mood instability (including depression) and bipolar disorder may have a pervasive personality component (i.e., hypomanic personality). Utilizing dimensional models of psychopathology, the current review examined the evidence linking narcissism and the bipolar disorders and suggests that considerable overlap may exist in the domains associated with reward-seeking, harm avoidance and social functioning.
自恋型人格障碍 (NPD) 和双相情感障碍中的躁狂和轻躁狂发作的特征是夸大妄想。这种共同的夸大妄想可能是一种“同源结构”，或者反映了两种截然不同的情况之间的表面相似性。然而，NPD 和双相情感障碍之间的关系可能比它们被划分为人格障碍和心境障碍这两个独立的上位类别所暗示的更为密切。虽然自恋被认为是一种贯穿一生的稳定特征，而双相情感障碍的特征是躁狂和抑郁发作，但有相当多的研究表明，自恋可能与情绪不稳定（包括抑郁）有关，而双相情感障碍可能具有普遍的人格成分（即轻躁狂人格）。本研究利用精神病理学的维度模型，考察了自恋与双相情感障碍之间的联系，并提出在与寻求奖励、回避伤害和社交功能相关的领域可能存在相当大的重叠。
