概括
老年人中创伤后应激障碍 (PTSD) 的生物标志物包括较高的血清BDNF和VEGF-A水平,以及较小的大脑体积. 不管PTSD诊断如何,BDNF基因型也会影响循环水平.
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.
- 老年学是一门学科.
背景情况:
- 创伤后应激障碍 (PTSD) 影响老年人,需要对其潜在的生物机制进行研究.
- 在这个人口群体中理解PTSD需要检查潜在的生物标志物,如细胞因子,神经营养因子和神经解剖学.
研究的目的:
- 研究患有PTSD和没有PTSD的老年人之间循环细胞因子,脑衍生神经营养因子 (BDNF),血管内皮生长因子 (VEGF-A) 和大脑体积的差异.
- 为了确定老年人中PTSD的潜在生物标志物.
主要方法:
- 测量了细胞因子 (IL-1β,IL-2,IL-4,IL-6,IL-12p70,IL17A,TNFα),BDNF和VEGF-A的血清水平.这些细胞因子的含量包括:
- 进行了BDNF基因型鉴定.
- 神经解剖学大脑体积 (灰质,白质,海马,杏仁体) 在女性子组中进行了评估.
主要成果:
- 在测试的细胞因子中没有发现显著差异.
- 血清BDNF和VEGF-A水平在PTSD组显著更高.
- Val66Met BDNF基因型载体的BDNF循环水平较低.
- 在患有PTSD的女性中观察到较小的灰质,白质和海马体积.
结论:
- 血清BDNF和VEGF-A,以及神经成像标记物,在老年人中显示为PTSD的生物标记物.
- 在BDNF Val66Met基因型影响循环BDNF水平.
- 需要进一步的研究来验证这些发现并探索治疗点.

Post-traumatic Stress Disorder
26
Post-traumatic stress disorder (PTSD) is a psychiatric condition that arises following exposure to traumatic events such as natural disasters, forced displacement, or severe accidents. It significantly impairs individuals' ability to cope with daily activities and disrupts their emotional and psychological equilibrium.
Symptoms and Behavioral Manifestations
A spectrum of distressing symptoms characterizes PTSD. Recurrent flashbacks, where individuals involuntarily relive traumatic events,...

Alzheimer's Disease: Overview
418
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...
