概括
血管风险因素在阿尔茨海默氏症和前性痴呆症等神经退行性疾病中很常见,对大脑白质完整性产生负面影响. 管理这些风险可能有助于减轻神经退行后果.
科学领域:
- 神经科学是一个神经科学.
- 老年学是一门学科.
- 心血管医学 心血管医学
背景情况:
- 血管风险因素在老年人中普遍存在,并与大脑损伤,白质超强度 (WMH),中风和痴呆症有关.
- 这些因素在各种神经退行性疾病中的特定流行率和影响以及它们与WMH的关联需要进一步探索.
研究的目的:
- 在五种不同的神经退行性疾病中调查血管风险负担和白质完整性之间的关联.
- 为了比较血管风险因子的患病率及其对轻度认知障碍/阿尔茨海默病 (MCI/AD),前性痴呆症 (FTD),脑血管疾病 (CVD),帕金森病 (PD) 和肌缩侧硬化症 (ALS) 患者对健康对照者的大脑结构的影响.
主要方法:
- 来自安大略省神经退行性疾病研究倡议 (ONDRI) 队列的520名参与者的横截面研究,包括患有MCI/AD,FTD,CVD,PD,ALS和健康对照的患者.
- 计算了血管风险指数 (VRI),评估高血压,糖尿病,失脂症,肥胖和吸烟史. 白质完整性通过3特斯拉MRI评估,使用宏观 (WMH体积) 和微观 (扩散张力成像) 测量.
- 统计分析包括多项逻辑回归和ANCOVA,根据年龄,性别,教育和APOE ε4状态进行调整.
主要成果:
- 血管风险因素,特别是高血压和高胆固醇血症,在疾病队列中比对照群更为常见.
- 较高的VRI与MCI/AD (1.5倍),FTD (1.7倍) 和CVD (2.6倍) 有显著关联.
- 在整体样本中,特别是在心血管疾病队列中,高的VRI与降低的宏观和微观结构白质完整性相关. APOE ε4 状态对这些协会的影响很小.
结论:
- 血管风险负担在MCI/AD,FTD和CVD等神经认知综合征中很常见,明显影响白质完整性.
- 这些发现强调了血管健康在神经退行过程中的重要作用.
- 需要进一步的研究来确定管理血管风险因素是否可以减轻受影响临床群体的神经退行症的结果.

Alzheimer's Disease: Overview
454
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...

Psychoneuroimmunology: Cardiovascular Disease
27
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...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Parkinson's Disease: Overview
499
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...
