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. 这表明病变的位置和负担有助于MS患者的抑郁症.
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) 是一种免疫媒介的神经系统疾病.
- 抑郁症会影响多达50%的MS患者.
- 白质网络破坏和MS抑郁症之间的关系需要进一步调查.
研究的目的:
- 调查白质网络破坏如何与MS患者的抑郁有关.
- 为了确定MS病变是否优先位于抑郁网络内.
- 检查病变负担,特别是抑郁症网络中的病变负担与MS中抑郁症的存在之间的联系.
主要方法:
- 利用电子健康记录识别了380名多发性硬化患者,根据诊断标准和查工具将他们分为MS+抑郁症 (n=232) 和MS-抑郁症 (n=148) 组.
- 获得了所有参与者的3T结构磁共振成像数据.
- 评估了抑郁网络中的病变位置偏好,并比较了两组之间的病变负担,重点关注抑郁网络中的病变.
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通道 (p < .001).
- 患有多发性硬化和抑郁症的个体表现出更大的整体损伤负担 (p = .015).
- 在MS+抑郁症组中,这种增加的病变负担是由位于抑郁症网络中的病变驱动的 (p = .020).
结论:
- 多发性硬化症病变的位置和负担是导致多发性硬化症抑郁症并发症的重要因素.
- 多发性硬化病变不成比例地影响大脑抑郁网络中的囊.
- 未来的研究应该探索与MS患者个性化抑郁症干预相关的损伤位置.

Depression: Overview
254
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,...

Long-term Depression
2.5K
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
136
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...
