The aim of this study was to investigate the number and type of brain abnormalities and their influence on psychosocial development, criminal history and paraphilias in sexual murderers. We analyzed psychiatric court reports of 166 sexual murderers and compared a group with notable signs of brain abnormalities (N = 50) with those without any signs (N = 116). Sexual murderers with brain abnormalities suffered more from early behavior problems. They were less likely to cohabitate with the victim at the time of the homicide and had more victims at the age of six years or younger. Psychiatric diagnoses revealed a higher total number of paraphilias: Transvestic fetishism and paraphilias not otherwise specified were more frequent in offenders with brain abnormalities. A binary logistic regression identified five predictors that accounted for 46.8% of the variance explaining the presence of brain abnormalities. Our results suggest the importance of a comprehensive neurological and psychological examination of this special offender group.
本研究的目的是调查性杀人犯大脑异常的数量和类型及其对心理社会发展、犯罪史和性偏好障碍的影响。我们分析了166名性杀人犯的精神病法庭报告，并将一组有明显大脑异常迹象的人（N = 50）与没有任何迹象的人（N = 116）进行了比较。有大脑异常的性杀人犯早期行为问题更多。他们在杀人时与受害者同居的可能性较小，并且在六岁或更小的时候有更多受害者。精神病诊断显示性偏好障碍的总数更高：异装癖和未另作说明的性偏好障碍在有大脑异常的罪犯中更为常见。二元逻辑回归确定了五个预测因素，它们占解释大脑异常存在的方差的46.8%。我们的结果表明，对这一特殊罪犯群体进行全面的神经学和心理学检查非常重要。
