概括
慢性腰部疼痛 (CLBP) 加快了大脑的衰老. 结合CLBP和年龄的影响导致结构和功能性大脑衰退,影响疼痛和潜在的认知.
科学领域:
- 神经科学是一个神经科学.
- 放射学 放射学是一门学科.
- 疼痛医学 医学 疼痛医学
背景情况:
- 慢性腰部疼痛 (CLBP) 是一种普遍的疾病,影响着不同年龄段的个人.
- 了解CLBP的长期神经后果,特别是它与衰老过程的相互作用,对于全面的患者护理至关重要.
研究的目的:
- 在患有CLBP的患者中,研究与认知相关区域的大脑结构和功能变化.
- 为了检查CLBP和年龄之间的相互作用如何影响这些大脑变化.
主要方法:
- 招募了76名CLBP患者,分为年轻 (20-29岁),中年 (30-39岁) 和年长 (40-49岁) 的年龄组.
- 利用功能磁共振成像 (fMRI) 进行大脑活动和连接分析.
- 进行了临床心理和疼痛症状评估.
主要成果:
- 与年轻患者相比,较年长的CLBP患者在轨道前皮层和上额前环中显示灰质体积减少.
- 在老年患者的前额皮层中,在中枢回环后和内侧中枢前额皮层中观察到静止状态大脑活动 (ALFF) 的显著差异.
- 在老年患者的右侧胰岛和背侧前额皮质,中年和老年患者的副海马回环和下额叶叶中,观察到功能连接性 (FC) 的下降.
- 大脑结构性质和FC值与年龄有显著的相关性.
结论:
- 似乎CLBP影响并可能加速大脑的衰老过程.

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Alzheimer's Disease: Overview
462
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...
