The aim of this study was to investigate etiological and nosological aspects of the schizotypal and borderline personality disorders. The sample consisted of 44 schizotypal, 15 schizotypal and borderline, and ten borderline same-sexed twin probands. The investigation of the co-twins indicated that genetic factors seemed to influence the development of the schizotypal, but not the borderline, personality disorders. The basic genetic core of the schizotypal syndrome seemed to consist of schizoid and paranoidlike features, and not psychoticlike cognitive and perceptual distortions. The study did not indicate any relationship between schizotypal and borderline personality disorders and affective and schizophrenic disorders. Further research is needed to confirm the independent status of the schizotypal syndrome in relation to the schizoid, avoidant, and paranoid personality disorders, and the borderline syndrome in relation to the histrionic , narcissistic, and antisocial personality disorders.
本研究的目的是调查分裂型人格障碍和边缘型人格障碍的病因学和分类学方面。样本包括44名分裂型、15名分裂型和边缘型以及10名边缘型同性别双胞胎先证者。对双胞胎的调查表明，遗传因素似乎影响分裂型人格障碍的发展，但不影响边缘型人格障碍。分裂型综合征的基本遗传核心似乎由类精神分裂症和类偏执特征组成，而不是类精神病性认知和感知扭曲。该研究未表明分裂型和边缘型人格障碍与情感障碍和精神分裂症之间存在任何关系。需要进一步研究以确认分裂型综合征相对于类精神分裂症、回避型和偏执型人格障碍的独立地位，以及边缘型综合征相对于表演型、自恋型和反社会型人格障碍的独立地位。
