概括
肌缩侧面硬化症 (ALS) 患者表现出加速的大脑衰老,大脑结构年龄 (BSA) 超过时间年龄. 这种加速衰老与认知能力下降相关,特别是执行功能障碍.
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:
- 肌缩侧面硬化症 (ALS) 是一种进展性神经退行性疾病.
- 病理性大脑衰老可能导致ALS的认知和功能衰退.
- 来自深度学习的脑结构年龄 (BSA) 为评估大脑衰老提供了一个新的指标.
研究的目的:
- 通过比较脑结构年龄 (BSA) 与时间年龄来研究ALS病理性脑衰老.
- 探索ALS患者BSA和认知/功能衰退之间的关联.
- 评估ALS中BSA的纵向进展情况.
主要方法:
- 在10名ALS患者和10名健康对照人群 (HCs) 中进行了纵向结构性MRI和认知评估.
- 使用volBrain平台估计的大脑结构年龄 (BSA).
- 认知领域和功能状态 (ALSFRS-R) 评估使用波斯适应性爱丁堡认知和行为ALS屏幕 (ECAS) 和ALSFRS-R.
主要成果:
- 与时间学年龄相比,ALS患者表现出明显加速的BSA (平均差异在基线+7.31年,随访+8.39年).
- 随着时间的推移,在ALS患者中观察到加速的BSA进展 (p = 0.004),与HC不同.
- 纵向BSA增加与执行功能下降 (r = -0.651,p = 0.042) 和视觉空间/全球认知恶化 (ALSFRS-R下降,r = 0.642,p = 0.045) 相相关.
结论:
- ALS的特征是加速的结构性大脑衰老,独立于时间年龄,与执行功能障碍有关.
- 高等教育可能会保持语言和口头流.
- BSA显示出作为跟踪ALS病理衰老的生物标志物的潜力.

Parkinson's Disease: Overview
319
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...

Alzheimer's Disease: Overview
323
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...
