- 生物标志物 生物标志物
背景情况:
- 胆固醇系统在帕金森病 (PD) 步行障碍中的作用尚未完全理解.
- 电脑电图 (EEG) 的α反应性是胆固醇功能的潜在指标.
- 在PD中研究EEGα反应性可能会揭示对步态障碍的洞察力.
研究的目的:
- 为了比较患有PD的个体与健康对照人群之间的EEGα反应.
- 为了检查EEGα反应性和PD中的步态参数之间的关联.
主要方法:
- 记录了20名PD患者和19名健康对照者的静止状态EEG (闭眼和开眼).
- 计算阿尔法反应性作为对头电极的阿尔法功率的相对变化.

Parkinson's Disease: Treatment

Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Parkinson's Disease: Overview
722
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...

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.
