概括

胰岛素抵抗 (IR) 和瘦素在情绪障碍中显著影响认知和灰质体积 (GMV),特别是在双极性障碍 (BD) 中. 这些发现表明与胰岛素相关的途径是BD认知缺陷的潜在治疗点.

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.
代谢障碍代谢障碍代谢障碍

背景情况:

大型抑郁症 (MDD) 和双极性障碍 (BD) 与持续的认知缺陷有关.
潜在的生物机制,特别是像胰岛素抵抗 (IR) 这样的代谢功能障碍,尚未完全理解.
代谢因素对大脑结构和认知的诊断特异性影响需要进一步探索.

研究的目的:

研究MDD和BD患者的代谢生物标志物,灰质体积 (GMV) 和认知表现之间的关联.
检查这些关联中的诊断特异性差异.
为了确定关键的代谢贡献者认知障碍在情绪障碍.

主要方法:

部分最小平方路径建模用于分析81名BD和78名MDD住院患者的数据.
神经心理学评估评估了认知功能.
T1加权的MRI提供了GMV数据,血液样本测量了代谢标记.

主要成果:

在整体样本中,代谢功能障碍对GMV和认知有负面预测,GMV对认知有积极影响.
在代谢-认知关系中观察到显著的诊断差异 (p = 0.0196).
在BD中,新陈代谢与减少的GMV和较差的认知密切相关,与MDD不同. 胰岛素耐药性标记物和瘦素是主要的代谢贡献者,影响对认知和情绪调节至关重要的脑部区域.

结论:

胰岛素抵抗 (IR) 和素在情绪障碍,特别是双极性障碍 (BD) 的认知功能中发挥着重要作用.
这些代谢因素影响灰质体积 (GMV) 和认知表现.
与胰岛素相关的途径代表了情绪障碍中认知缺陷的有希望的治疗标,特别是当与代谢条件同时发生时.

Gut-Brain Axis

Gut-Brain Axis

The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...

Alzheimer Disease ll: Pathophysiology

Alzheimer Disease ll: Pathophysiology

Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
