概括
早期帕金森病 (PD) 发言障碍与运动严重程度和骨中多巴胺减少有关,而不是CSF生物标志物. 有针对性的干预措施需要进一步的研究.
科学领域:
- 神经学 神经学
- 语言病理学 语音病理学
- 生物标志物研究 生物标志物研究
背景情况:
- 语音困难是帕金森病 (PD) 的早期和残疾症状,严重影响了沟通和生活质量.
- 了解早期PD中这些语言问题的相关性对于及时干预至关重要.
- 这项研究区分了以前没有接受过治疗的早期PD患者和接受过Levodopa治疗的早期PD患者.
研究的目的:
- 调查与早期帕金森病的言语困难相关的人口统计学,临床,多巴胺成像和脑脊液 (CSF) 因素.
- 为了比较以前未接受过治疗的早期PD患者群体和接受过Levodopa治疗的早期PD患者群体之间的这些相关性.
主要方法:
- 来自帕金森病进展标记计划 (PPMI) 队列的数据的横截面分析.
- 包括376名以前没有接受过治疗的PD参与者和133名接受过levodopa治疗的PD早期参与者.
- 使用运动障碍学会统一的帕金森病评级表 (MDS-UPDRS) 评估的言语困难,第三部分,第3.1项. 使用二进制物流回归分析的预测器,包括 [123I]FP-CIT特定绑定比率 (SBR).
主要成果:
- 在44%的未接受过治疗的参与者和57%的接受过乐伏多巴治疗的参与者中,言语困难普遍存在.
- 在这两组中,较高的MDS-UPDRS Part III ON分数 (运动严重程度) 和较低的平均布坦SBR (多巴胺损失) 是显著的预测因素.
- 在未接受治疗的组中,年龄预测了语言障碍;CSF生物标志物没有显著差异.
结论:
- 早期与PD相关的语言困难主要与多巴胺基和运动功能障碍有关,特别是膜中的条状多巴胺基损失.
- 在CSF的全球神经退行性标志物似乎无法区分早期语言障碍的个体.
- 建议进行纵向多模式研究,以了解语音衰退的神经基础,并制定有针对性的干预措施.

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.

Parkinson's Disease: Overview
2.2K
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
1.4K
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 Disease l: Introduction
28
Parkinson’s disease is a chronic, progressive neurodegenerative disorder that primarily affects movement. It is characterized by motor symptoms such as resting tremors, muscle rigidity, bradykinesia (slowness of movement), and postural instability. Patients may notice hand tremors at rest, stiffness during movement, or a shuffling gait. In addition to motor features, non-motor symptoms include sleep disturbances, mood and behavioral changes, constipation, and cognitive impairment, all of...

Parkinson Disease ll: Pathophysiology
28
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...

Alterations in Muscle Tone lll
29
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
