- 轻度认知障碍 (MCI) 是帕金森病 (PD) 的常见并发症.
- 遗传突变,特别是LRRK2和GBA1基因,与PD相关.
- 了解基因定义的PD亚型中MCI发生率对于早期诊断和管理至关重要.
研究的目的:
- 为了确定MCI在早期帕金森病 (PD) 患者的发病率.

- 在不同的PD遗传组中应用运动障碍学会 (MDS) 的MCI诊断标准.
主要方法:
- 患PD患者的纳入标准:霍恩和雅尔得分≤2和≤6年自运动症状发作以来.
- 使用神经心理学电池进行认知评估,涉及五个领域:执行功能,工作记忆,记忆,视觉空间和语言.
- 使用两种方法 (I级和II级) 评估MCI,并比较PD组和健康对照组之间的MCI频率.
主要成果:
- 这项研究包括70名IPD,42名LRRK2-PD,83名GBA1-PD患者和132名对照患者.

Parkinson's Disease: Overview
537
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...

Parkinson's Disease: Treatment
264
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.

Neural Regulation
39.4K
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.

Lysosomal Hydrolases
3.8K
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
