摘 要:目的 探讨慢性失眠患者空间记忆与睡眠结构及海马体积的关系.方法 选取2013年10月至2015年11月于山东大学附属千佛山医院睡眠障碍门诊就诊的22例慢性失眠患者(慢性失眠组)和17名睡眠健康者(对照组),采用匹兹堡睡眠质量指数量表、埃普沃思思睡量表、失眠严重程度指数量表和多导睡眠图评估受试者的睡眠质量和失眠严重程度,蒙特利尔认知评估量表和九盒迷宫评价受试者的认知及空间记忆功能,MRI测定受试者双侧海马体积.结果 慢性失眠组较对照组睡眠总时间缩短[分别为328.3 (310.4, 387.9)、418.0 (375.8, 45.5) min, Z=2.607,P=0.009]、入睡潜伏期延长[27.3 (13.1, 33.3)、5.5 (3.3, 7.3) min, Z=4.534,P=0.000]、睡眠效率(%)降低[77.7 (73.1, 84.0)、93.0 (87.2, 93.9), Z=3.739,P=0.000]、入睡后觉醒时间延长[59.3 (41.1, 106.6)、26.5 (19.5, 36.8) min, Z=3.244,P=0.001]、N3期比例(%)降低[5.5 (0.4, 14.4)、13.7 (7.7, 18.3), Z=2.664,P=0.008]、快速眼球运动(REM)期比例(%)降低[14.4 (10.7, 17.2)、17.3 (15.9, 23.3), Z=2.890,P=0.004].慢性失眠组较对照组物体工作记忆[错误数分别为1.0 (0.0, 1.3)、0.0 (0.0, 0.0), Z=2.317,P=0.020]、空间工作记忆[错误数分别为4.5 (2.0, 7.3)、1.0 (0.0, 3.0), Z=3.007,P=0.003]差.两组间物体参考记忆、空间参考记忆以及物体再认差异无统计学意义.慢性失眠组较对照组左侧海马体积[2 818.0 (2 534.9, 3 191.8)、3 453.3 (3 081.2, 3 764.4) mm^3, Z=3.314,P=0.001]、标准化右侧海马体积[2 780.5 (2 451.2, 3 191.8)、3 479.8 (3 024.1, 3 786.7) mm^3, Z=3.484,P=0.000]、标准化总海马体积[5 561.7(4 956.6, 6 396.9)、6 898.9 (6 017.1, 7 540.1) mm^3, Z=3.455,P=0.001]均缩小.睡眠效率、N3期比例与海马体积呈正相关(r=0.323、0.376,P=0.045、0.018),睡眠潜伏期与海马体积呈负相关(r=-0.432,P=0.006);海马体积与空�Objective To investigate the correlation between spatial memory and sleep architecture and hippocampal volumes in patients with chronic insomnia disorder.Methods Twenty-two chronic insomnia patients and 17 normal sleepers (controls) were selected to evaluate the subjective insomnia using Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI) and the objective insomnia by polysomnography (PSG).The cognitive function was measured by Montreal Cognitive Assessment (MoCA).Spatial memory and object-memory were measured by Nine-box Maze, and object-recognition memory was detected by picture recognition test.MRI was used to detect hippocampus volumes.Results Compared with controls, a significant reduction in total sleep time (328.3 (310.4, 387.9) min vs 418.0 (375.8, 45.5) min, Z=2.607, P=0.009), sleep efficiency (%) (77.7 (73.1, 84.0) vs 93.0 (87.2, 93.9), Z=3.739,P=0.000), proportion of N3 (%) (5.5 (0.4, 14.4) vs 13.7 (7.7, 18.3), Z=2.664, P=0.008) and proportion of rapid eye movement (REM) (%) (14.4 (10.7, 17.2) vs 17.3 (15.9, 23.3), Z=2.890, P=0.004) was seen in insomnia patients, whereas sleep latency was delayed.The error numbers of spatial working-memory (4.5 (2.0, 7.3) vs 1.0 (0.0, 3.0), Z=3.007, P=0.003) in chronic insomnia patients were more than those in controls.There was no statistically significant difference in object reference memory, spatial reference memory and object recognition in two groups.A significant reduction of the left (2 818.0 (2 534.9, 3 191.8) mm^3 vs 3 453.3 (3 081.2, 3 764.4) mm^3, Z=3.314, P=0.001), right (2 780.5 (2 451.2, 3 191.8) mm^3 vs 3 479.8 (3 024.1, 3 786.7) mm^3, Z=3.484,P=0.000) and whole hippocampal volumes (5 561.7 (4 956.6, 6 396.9) mm^3 vs 6 898.9 (6 017.1, 7 540.1) mm^3, Z=3.455, P=0.001) was seen in chronic insomnia patients compared with controls.The hippocampal volumes were negatively corre
