- 了解这些并发症对于管理iNPH患者至关重要.
研究的目的:
- 研究生物检查发现的病理,包括粉样β (Aβ),对iNPH患者的VP转移结果的影响.
- 评估活检和粉样质正电子发射断层扫描 (PET) 和多巴胺载体 (DAT) 成像在预测结果中的作用之间的一致性.
主要方法:
- 评估了58名接受VP转移的iNPH患者.
- 利用皮质活检进行病理学评估 (包括Aβ) 和粉样蛋白PET.
- 检查了iNPH指数,DAT成像和活检结果,以了解它们对术后结果的影响.
主要成果:
- 在39.7%的患者中存在Aβ病理,与粉样蛋白PET具有很高的一致性.

01:15Parkinson's Disease: Overview
1.7K
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...

4.4K
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,...
