概括

炎症,特别是瘤亡因子 (TNF) 的升高,与患有严重抑郁症 (MDD) 的美洲印第安人的大脑奖励处理受损有关. 这突显了炎症.

科学领域:

神经科学是一个神经科学.
精神病学是一个精神病学.
免疫学免疫学免疫学

背景情况:

美国印第安人 (AIs) 面临慢性压力因素,导致较高的抑郁症 (MDD) 发病率.
压力引起的炎症与MDD病理生理学和奖励处理缺陷有关.
这项研究检查了AI个体中MDD的炎症在奖励处理中的作用.

研究的目的:

在患有MDD的美洲印第安人中调查炎症生物标志物和奖励预期期间的神经反应之间的关联.
确定炎症是否有助于在这个人群中破坏奖励处理.

主要方法:

73名患有终身MDD的美国印第安人参与者在货币激励延迟任务期间同时接受了EEG和fMRI.
血液样本被分析为促炎性 (TNF,IL-6,CRP) 和抗炎性 (IL-10) 细胞因子.
抑郁症的严重程度使用PROMIS抑郁症量表来衡量.

主要成果:

瘤亡因子 (TNF) 和CRP度的升高与奖励预期 (获取和损失) 期间基底腺激活的减少有关.
性别和药物状态也预测了基底质的神经反应.
介质素-10 (IL-10),介质素-6 (IL-6) 和P300显示出最小的预测值.

Depressive Disorders: MDD and Dysthymia

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Depression: Overview

Depression: Overview

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,...
