概括
在双相情感障碍 (BD) 中,白质 (WM) 完整性随着疾病的进展而恶化,特别是在更多的躁狂发作时. 先进阶段显示更严重的WM中断,影响全球运行.
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.
- 神经科学是一个神经科学.
背景情况:
- 双极性障碍 (BD) 理论上是随着时间的推移而进展的,但它对白质 (WM) 微观结构的影响尚未完全理解.
- 本研究使用临床分期模型研究了WM完整性和BD疾病进展之间的关系.
研究的目的:
- 探索白质 (WM) 微观结构与双相情感障碍 (BD) 疾病进展之间的关联.
- 检查WM完整性如何与躁狂发作数量,缓解质量和BD患者的整体功能有关.
主要方法:
- 截面扩散张力成像 (DTI) 研究涉及153名BD患者和153名健康对照 (HCs).
- 基于通道的空间统计 (TBSS) 用于分析分数异构性 (FA) 和其与临床分期标准的关联.
- 基于躁狂发作数量,缓解质量和发作间全球功能的临床分期.
主要成果:
- 根据躁狂发作数量,在BD早期和晚期之间发现了WM完整性 (FA) 的显著差异.
- 与稳定缓解患者相比,患有持续症状的BD患者表现出更广泛的FA差异.
- 优性BD患者的全球功能与FA有积极的关联,表明更好的WM完整性.
结论:
- 在双相情感障碍 (BD) 的晚期阶段观察到更严重的白质 (WM) 干扰.
- 结果表明WM变化可能与疾病进展并行,尽管由于横截面设计,不能排除稳定的临床亚型.
- 突出了BD中WM变化的临床相关性和纵向研究的需要.

01:30Bipolar Disorder
628
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

01:26Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
