背景情况:
- 非自杀性自我伤害 (NSSI) 在患有抑郁症的青少年中很常见,是自杀的重要危险因素.
- 关于连接青少年抑郁症和NSSI行为的神经成像机制的研究有限.
研究的目的:
- 在患有抑郁症的青少年中调查前额叶皮层功能连接 (FC) 的变化.
- 探索这些FC变化与NSSI行为之间的关系.
主要方法:
- 从35名患有抑郁症的青少年和33名健康对照组中收集的fMRI数据.
- 计算了前额叶皮层功能连接 (FC) 并与抑郁症和NSSI分数相关.
- 使用了17项的汉密尔顿抑郁评分表 (17-HAMD) 和太华自我伤害库存.
主要成果:
- 患有抑郁症的青少年在右眼前视野,左脊侧前额叶皮质,右轨道前额叶皮质,左胰岛和右前带状皮质等区域显示了CF的下降.
- 在17-HAMD得分和NSSI频率 (r=0.461,p=0.005) 之间发现了正相关性.
- 在FC (右前带带皮层-右前皮层) 和17-HAMD得分 (r=-0.401,p=0.023) 之间,以及在FC (右轨道前皮层-右岛) 和NSSI频率 (r=-0.438,p=0.012) 之间观察到负相关性.
结论:
- 青少年抑郁症与前额叶皮层功能连接性降低有关.
- 特定的FC变化与NSSI频率相关,为抑郁症和NSSI之间的联系提供神经成像证据.

Depression is a prevalent mental illness marked by persistent sadness and lack of interest in previously enjoyable activities. It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts. From a neurobiological perspective, depression is believed to be triggered by abnormalities in the brain's prefrontal cortex,...
