概括
大型抑郁症 (MDD) 在大脑层次结构中表现出改变的结构功能合 (SFC). 抗抑郁药物反应与层次特定的SFC变化有关,提供预测性见解.
科学领域:
- 神经科学是一个神经科学.
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
背景情况:
- 大型抑郁症 (MDD) 与改变的大脑网络有关,但结构功能合 (SFC) 发现不一致.
- 大脑的功能层次结构可以解释SFC和MDD病理学的变化.
- 跨功能层面调查SFC对于理解MDD和治疗反应至关重要.
研究的目的:
- 与健康对照组 (HC) 相比,研究主要抑郁症 (MDD) 患者结构功能合 (SFC) 的变化.
- 检查MDD中SFC和抗抑郁药反应之间的关系.
- 从功能层次的角度分析SFC变化.
主要方法:
- 在MDD患者 (n=258) 和HC (n=99) 中使用静止状态fMRI和扩散张力成像进行区域SFC比较.
- 评估了抗抑郁药不响应者 (n=55) 和响应者 (n=68) 之间的SFC差异.
- 根据主要梯度值对区域进行排名,以评估层级特定的SFC模式.
主要成果:
- 患有MDD的患者在单模区域 (低梯度) 显示SFC增加,在跨模区域 (高梯度) 显示SFC降低,而不是HC.
- 抗抑郁药物反应者在单模区域表现出更高的SFC,在注意网络中表现出更低的SFC.
- 在功能层次结构中观察到SFC的显著差异 (p < 0.001).
结论:
- MDD病理包括在低级单模和高级跨模网络中对立SFC变化.
- 跨功能层次的SFC变化突出显示了MDD中的空间异质性.
- 层次特定的抗抑郁药效应有可能预测MDD的治疗结果.

Antidepressant Drugs: MAOIs and Other Agents
228
Atypical antidepressants, including bupropion (Wellbutrin), mirtazapine (Remeron), nefazodone (Serzone), trazodone (Desyrel), and vilazodone (Viibryd), offer unique mechanisms of action. Bupropion weakly inhibits dopamine and norepinephrine reuptake, aiding depression treatment and smoking cessation, with a low risk of sexual dysfunction. Mirtazapine enhances serotonin and norepinephrine neurotransmission, leading to sedation, increased appetite, and weight gain. As a result, it helps treat...

Antidepressant Drugs: Overview
467
Antidepressant drugs are a class of medications primarily used for treating various mood disorders, including major depression, anxiety disorders, and other related conditions. These medicines work by modulating the neurotransmitter balance within the brain, alleviating depressive symptoms. Antidepressants can be broadly categorized into several groups according to their mechanism of action and chemical structure: Selective Serotonin Reuptake Inhibitors (SSRIs), Serotonin-Norepinephrine...

Tricyclic Antidepressants (TCAs), including Desipramine (Norpramin), Imipramine (Tofranil), Clomipramine (Anafranil), and Amitriptyline (Elavil), inhibit serotonin and norepinephrine reuptake and also block other receptors. They are used for depression, pain conditions, and insomnia. Common adverse effects include anticholinergic effects, sedation, orthostatic hypotension, and weight gain. They have a narrow therapeutic window and so require plasma-level monitoring. Abrupt discontinuation can...

G-protein Coupled Receptors
118.6K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Depressive Disorders: Etiology
83
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...

Depression: Overview
242
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,...
