An earlier report described symptoms and background features in depressed probands grouped by polarity: bipolar I, bipolar II, and nonbipolar. The present study made similar comparisons among relatives with a lifetime history of major depression. The 73 relatives with bipolar II disorder had the highest rates of marital disruption, psychopathology in the previous month, nonserious suicide attempts, and nonaffective syndromes and were the youngest when first treated.
双相 I 型、双相 II 型和非双相型。本研究对有重度抑郁终生史的亲属进行了类似的比较。73 名患有双相 II 型障碍的亲属婚姻破裂率、前一个月的精神病理学、非严重自杀未遂和非情感综合征发生率最高,且首次接受治疗时最年轻。
