概括
心血管疾病风险加速大脑衰老,影响特定的大脑区域比其他区域更大. 区域大脑年龄差距分析揭示了这些漏洞,提供了关于血管对认知衰退的贡献的见解.
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.
- 老年学是一门学科.
背景情况:
- 心血管疾病 (CVD) 和其危险因素与加速的神经退行和认知衰退有关.
- 大脑年龄差距 (BAG) 量化了预测的大脑年龄和时间表年龄之间的差异.
- 之前的研究集中在全球BAG;这项研究调查了特定区域的协会.
研究的目的:
- 检查心血管疾病 (CVD) 风险,认知功能和区域大脑年龄差距 (BAG) 之间的关系.
- 确定特定的皮质区域容易受到心血管疾病风险负担.
- 了解血管对大脑衰老和认知衰退的贡献.
主要方法:
- 分析了187名参与老化大脑队列 (ABC) 的横截面数据.
- 从MRI扫描中使用volBrain自动化管道计算全球和区域BAG.
- 用QRISK3评估心血管疾病风险,计算10年心血管疾病风险和心脏年龄差距 (HAG);用MoCA测量认知功能.
主要成果:
- 10年心血管疾病风险和HAG与全球BAG显著相关.
- 在特定因素 (3-6) 中的BAG与心血管疾病风险和HAG正相关,表明区域脆弱性.
- 认知指标 (总的MOCA,语言,执行指数) 在特定因素中显示出与BAG的负相关性.
结论:
- 心血管疾病风险与全球和区域大脑衰老有关.
- 特定的皮质区域对心血管疾病风险的脆弱性增加.
- 区域BAG分析提供了比全球估计更精确的脑衰老异质性和血管贡献的见解.

Cognitive Development During Adulthood
772
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Psychoneuroimmunology: Cardiovascular Disease
391
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
