Eight patients are described in whom either hypersexuality (four cases) or change in sexual preference (four cases) occurred following brain injury. In this series disinhibition of sexual activity and hypersexuality followed medial basal-frontal or diencephalic injury. This contrasted with the patients demonstrating altered sexual preference whose injuries involved limbic system structures. In some patients altered sexual behaviour may be the presenting or dominant feature of brain injury.

本文描述了8例脑损伤后出现性欲亢进（4例）或性偏好改变（4例）的患者。在这组病例中，内侧基底额叶或间脑损伤后出现了性活动脱抑制和性欲亢进。这与性偏好改变的患者形成对比，后者的损伤涉及边缘系统结构。在一些患者中，性行为改变可能是脑损伤的主要表现或突出特征。
