The suprachiasmatic nucleus (SCN) plays a critical role in maintaining melatonin and sleep-wake cycles.
METHODS/PATIENT: We report a case of 38-year-old woman who, after gunshot wound to the right temple, developed a sleep complaint of multiple nocturnal awakenings and several naps throughout the day.
Computerized tomography and magnetic resonance imaging revealed bilateral optic nerve and optic chiasm damage. Diagnostic polysomnography and actigraphy revealed an irregular sleep wake rhythm.
We speculate concurrent damage of the SCN and optic nerves bilaterally resulted in the posttraumatic irregular sleep-wake rhythm.
视交叉上核(SCN)在维持褪黑素和睡眠-觉醒周期方面起着关键作用。
方法/患者:我们报告了一例 38 岁女性的病例,该女性因右太阳穴枪击伤后出现睡眠问题,表现为多次夜间醒来和白天多次小睡。
计算机断层扫描和磁共振成像显示双侧视神经和视交叉损伤。诊断性多导睡眠图和活动记录仪显示不规则的睡眠-觉醒节律。
我们推测 SCN 和双侧视神经的并发损伤导致了创伤后不规则的睡眠-觉醒节律。
