Over 50% of individuals who suffer traumatic brain injury (TBI) demonstrate a decrease in sexual arousal post-injury. This study investigated the basis of this loss and hypothesized that it occurred as a consequence of the effect of the injury on cognition: specifically, diminution of the ability to form and manipulate sexually arousing imagery. The study compared 14 male participants who identified themselves as having alteration in sexual functioning following traumatic brain injury with a further 14 non-brain injured participants, case matched to them for age and education. All TBI participants were assessed after 2 years following injury, and had had a loss of consciousness of 3 days or greater. The results indicated that the two groups differed in terms of their performance on the Bett's QMI Scale, the Gordon Test of Visual Imagery Control, the Vividness of Sexual Imagery Scale of the Imaginal Processes Inventory, the State Trait Anxiety Inventory, and the Beck Depression Inventory. After correction for the level of depression by analysis of covariance, the TBI participants still featured lower levels of performance on the Sexual Imagery sub-scale of the Imaginary Processes Inventory. The results indicate that sexual arousal disturbances may exist above and beyond the disturbances to affect associated with the psychosocial effects of the TBI.
超过50%的创伤性脑损伤（TBI）患者在受伤后出现性唤起下降。本研究调查了这种下降的原因，并假设其是由损伤对认知的影响导致的：具体而言，是形成和处理性唤起意象的能力下降。该研究将14名自称在创伤性脑损伤后性功能发生改变的男性参与者与另外14名非脑损伤参与者进行了比较，后者在年龄和教育程度上与前者进行了病例匹配。所有TBI参与者在受伤2年后接受评估，且曾有3天或更长时间的意识丧失。结果表明，两组在贝茨QMI量表、戈登视觉意象控制测试、意象过程量表的性意象生动性量表、状态特质焦虑量表和贝克抑郁量表上的表现存在差异。通过协方差分析校正抑郁水平后，TBI参与者在意象过程量表的性意象子量表上的表现仍较低。结果表明，性唤起障碍可能独立于TBI的心理社会影响所导致的相关障碍而存在。
