概括
患有抑郁症的多发性硬化症 (MS) 患者表现出白质病变,优先影响大脑的抑郁网络. 这表明MS相关的白质损伤和抑郁症状之间存在联系.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 精神病学是一个精神病学.
背景情况:
- 多发性硬化症 (MS) 是一种严重的神经系统疾病,在美国影响近100万人.
- 抑郁症是一种常见的并发症,影响多达50%的MS患者.
研究的目的:
- 研究MS患者白质网络破坏和抑郁症之间的关系.
- 为了确定MS病变是否优先位于大脑的抑郁网络内.
主要方法:
- 一项回顾性病例控制研究分析了783名患有MS的参与者的3特斯拉神经成像数据.
- 根据诊断码,药物和查工具,参与者被分为患有抑郁症的MS (MS+抑郁症) 和没有抑郁症的MS (MS-抑郁症) 组.
- 线性混合效应模型被用来在组之间比较抑郁网络内外的损伤负担.
主要成果:
- 发现MS病变与其他大脑区域相比,在抑郁网络内优先影响白质束 (P<0.001).
- 患有MS+抑郁症的患者整体白质病变负担较大 (P=0.015).
- 在MS+抑郁症组中,这种增加的负担是由位于抑郁症网络中的病变驱动的 (P=0.020).
结论:
- 这项研究提供了令人信服的证据,将白质网络中断与MS抑郁症联系起来.
- 多发性硬化病变不成比例地影响抑郁网络,这表明这种人群中抑郁症的神经解剖学基础.
- 这些发现凸显了考虑病变位置的重要性,以便在MS患者中开发个性化抑郁症干预措施.

Depression: Overview
281
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: Etiology
140
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...

Long-term Depression
2.6K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Depressive Disorders: MDD and Dysthymia
176
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...
