概括

使用fMRI的voxel-mirrored homotopic连接 (VMHC) 可以区分主要抑郁症 (MDD) 的严重程度. 减少某些大脑区域的VMHC和增加其他区域的连接性与抑郁水平相关,有助于诊断.

科学领域:

神经成像是一种神经成像.
精神病学是一个精神病学.
大脑的连接性大脑的连接性

背景情况:

大型抑郁症 (MDD) 显著影响日常功能,需要精确的严重程度分层来进行有效的治疗.
休息状态功能磁共振成像 (fMRI) 为MDD评估提供了潜在的神经成像生物标志物.

研究的目的:

评估voxel-mirrored homotopic connectivity (VMHC) 作为一个神经成像生物标志物,用于区分MDD严重程度.
调查轻度至中度和重度MDD患者之间的VMHC差异及其与抑郁症得分的相关性.

主要方法:

分析了来自REST-meta-MDD项目的392名第一期MDD患者和440名健康对照 (HC) 的休息状态fMRI数据.
用汉密尔顿抑郁量表 (HAMD) 评分将MDD患者分为轻度至中度和重度的组.
检查VMHC差异和与HAMD得分的相关性,包括接收器操作特征 (ROC) 曲线分析.

主要成果:

在状回旋 (轻度至中度的MDD与HC) 观察到显著的VMHC减少,并扩展到胰岛,后中心和角回旋 (严重的MDD).
与轻度至中度MDD患者相比,在重度MDD患者中发现了中间带状皮质VMHC的增加,与HAMD得分呈正相关.
VMHC有效地将MDD患者与HC患者以及不同抑郁症严重程度的患者区分开来.

结论:

VMHC作为一个有前途的神经成像生物标志物用于临床诊断和MDD严重程度的分层.
这些发现为MDD严重程度的神经生物学基础提供了洞察力.

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,...

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...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
