认知和行为障碍在患有SOD1基因变异的肌缩侧面硬化症 (ALS) 患者中比以前认为的更为常见. 这些SOD1-ALS患者在社会认知和语言方面表现出特殊的缺陷.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 遗传学 是一个
- 神经学 神经学
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.
- 患有C9orf72扩张的ALS患者的认知行为特征得到了充分证实.
- 对SOD1-ALS认知行为特征的理解是有限的,通常基于病例报告.
研究的目的:
- 为了全面调查ALS患者与SOD1基因变异的认知行为特征.
- 为了比较SOD1-ALS患者与野生型ALS (WT-ALS) 和健康对照.

Parkinson's Disease: Overview
541
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
469
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...
