概括
帕金森病 (PD) 患者的早期下 (嗅觉受损) 和dysautonomia (自主功能障碍) 显示出患PD痴呆症 (PDD) 的风险更大,运动症状进展更快. 这突显了这些非运动症状在早期PD的预后意义.
科学领域:
- 神经学 神经学
- 神经科学是一个神经科学.
- 老年学是一门学科.
背景情况:
- 嗅觉功能障碍和脱机症是帕金森病 (PD) 的早期非运动症状.
- 这些症状可以在PD的前阶段表现出来.
- 了解它们的预后价值对于早期干预至关重要.
研究的目的:
- 在新发帕金森病患者中调查并发性dysautonomia和hyposmia的预后影响.
- 为了比较患有这些早期非运动性症状的患者和没有这些早期非运动性症状的患者之间的帕金森病痴呆 (PDD) 转化,运动并发症的发展和乐伏多巴等效剂量 (LED) 变化的风险.
主要方法:
- 一项逆行队列研究包括105名新诊断的PD患者.
- 通过嗅觉识别测试 (CC-SIT),自主功能测试 (AFT) 和多巴胺转运器 (DAT) 扫描来评估患者.
- 为了进行比较分析,患者被分为低血+/不自律性+ (H+/D+) 和低血-/不自律性- (H-/D-) 组.
主要成果:
- H+/D+组显示了改变的DAT扫描模式,包括较低的吸收值和更的腹脊梯度.
- 在H+/D+组的患者表现出较差的执行功能和显著更高的PDD发展风险.
- 虽然运动并发症的风险相似,但H+/D+组的LED增加速度更快.
结论:
- 在新发病的PD患者中,同时出现的低血压和双自律症与PDD转换的风险增加有关.
- 这些早期的非运动症状预示着运动症状的更快的进展,由更快的LED增加表明.
- 这些发现强调了评估嗅觉和自主功能对于早期PD预后的重要性.

Parkinson's Disease: Overview
528
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
261
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.

Disorders of the Autonomic Nervous System
625
The autonomic nervous system (ANS) is an intricate network of nerves that controls functions such as the regulation of heart rate, digestion, and blood pressure regulation. When this system malfunctions, it can lead to various disorders that affect multiple bodily functions. One common feature of many autonomic disorders is the involvement of smooth blood vessels, which play a crucial role in regulating blood flow throughout the body.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
580
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

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,...
