概括
患有帕金森病 (PD) 的人表现出保留在语音中标记突出的单词的能力,尽管他们使用音调 (f0) 的效果不如对照组. 这表明在PD中保持了沟通性语音的某些方面.
科学领域:
- 语音病理学
- 神经科学
- 声学语音学
背景情况:
- 帕金森病 (PD) 通常会影响语言表达,影响理解能力和沟通能力.
- 了解PD患者如何表达语言强调 (突出) 对于有针对性的治疗至关重要.
研究的目的:
- 研究帕金森病 (PD) 患者在沟通任务中对单词突出性的声学认识.
- 将PD患者与神经健康人群之间的突出标记策略进行比较.
主要方法:
- 参与者 (12名患有PD,14名对照者) 在障碍游戏中大声读取说明.
- 声学分析测量了突出和非突出单词的语音强度,持续时间和基本频率 (f0).
- 使用不同起始辅音的最小对来操纵单词的突出性.
主要成果:
- 与对照组相比,患有PD的人使用类似的语音强度和持续时间来标记突出词汇.
- 在PD小组中,使用f0变化来指示单词突出度减少.
- 各组之间观察到母音形成差异,但与突出标记不一致.
结论:
- 帕金森病患者在沟通过程中在很大程度上保留了发声的突出标记.
- 虽然保持了整体突出标记,但声学策略,特别是使用,在PD患者和对照者之间有所不同.
- 研究结果表明,语音治疗可以提高帕金森病患者的沟通效率.

Parkinson's Disease: Overview
703
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
377
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

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.

Therapeutic Communication

Communication is a lifelong learning process. Through therapeutic communication, nurses can collect relevant assessment data, provide education and counseling, and interact during nursing interventions. Sending and receiving messages occur through verbal and nonverbal communication techniques and can happen separately or simultaneously.
Verbal communication depends on language or a prescribed way of using words so that people can share information effectively. The critical aspects of verbal...

Alzheimer's Disease: Treatment
260
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

Higher Mental Functions of the Brain: Language
1.0K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...
