背景情况:
- 步行障碍是渐进性超核麻 (PSP) 的关键诊断特征.
- 执行功能,一种认知领域,可能会影响PSP患者的步态特征.
- 了解这种关系对于管理PSP和预防跌倒至关重要.
研究的目的:
- 研究PSP患者执行功能与步态之间的关系.
- 用纵向数据来确定这种关系是否随着时间的推移而持续.
- 探索口头流利任务作为PSP执行功能的衡量标准的作用.
主要方法:
- 评估了26名PSP参与者,其中17人在5次访问中进行了纵向跟踪.
- 临床症状使用PSP评分尺度 (PSPRS) 进行评估.
- 执行功能是通过语音和语义语言流利任务来衡量的. 步行参数 (速度,步伐长度,变化) 在步行任务期间客观地使用可穿戴传感器测量.
主要成果:
- 更高的语义流与整体PSP症状严重程度较低相关 (p=0.008).
- 语义流性增加与步行速度变化 (p=0.027) 和步伐长度变化 (p=0.041) 的减少有关.

01:15Parkinson's Disease: Overview
704
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...

Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.

380
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.
