概括
帕金森病 (PD) 语音治疗改善了声音的强度,但没有增强语言的产生,包括动词的使用. 这表明,运动系统的支持并不能直接改善PD患者的复杂语言技能.
科学领域:
- 神经学 神经学
- 语音语言病理学 语音语言病理学
- 认知科学 认知科学
背景情况:
- 帕金森病 (PD) 经常会影响沟通,影响声音,言语和语言.
- 患有PD的个体可能表现出动词产生和理解方面的缺陷,可能与运动和语义系统相互作用有关.
- 患PD的认知变化也可能导致复杂语法困难,这与动词使用有关.
研究的目的:
- 调查通过运动系统支持提高声高是否会影响帕金森病患者口语话语中的词汇语义,语法或信息性.
- 为了确定语音运动干预是否可以改善帕金森病的语言生产缺陷.
主要方法:
- 一项研究比较了20名对照参与者和39名患有PD的图片描述叙述.
- 19名患有PD的参与者接受了李·西尔弗曼语音治疗 (LSVT LOUD®).
- 在治疗前和治疗后,对叙述进行了语言特征 (每次发言的动词,语义,语法,信息性) 的分析,比较治疗PD,未治疗PD和对照组.
主要成果:
- 在治疗PD组的干预后观察到声音大声的显著增加.
- 干预后没有发现语言表现 (词汇语义,语法,信息性) 的显著变化.
- 虽然对照组与整体PD组在每次发言中的动词上有所不同,但这主要是由于未接受治疗的PD参与者,这表明了高度的变化.
结论:
- 针对语音运动系统来提高声音的声音,似乎并没有提高帕金森病患者的语言生产.
- 这些发现不支持运动专注语音治疗改善PD口语话语的词法语义或语法方面的假设.
- 在语言生产措施中存在相当大的变化,特别是在动词使用中,在不同群体和帕金森病患者群体中存在相当大的变化.

Parkinson's Disease: Treatment

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's Disease: Overview
527
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...

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.

Techniques of Therapeutic Communication II: Focusing, Paraphrasing, and Summarizing

Focusing involves centering a conversation on a message's critical elements or concepts. Focusing is valuable if the talk is vague or patients begin to repeat themselves. Sometimes, when patients are asked about their symptoms, they may go off-topic and try to tell their entire life story. Respectfully, the nurse should bring the conversation back into focus.
This therapeutic technique can also be used when a patient brings up pertinent information during a health-related conversation. The...

Alzheimer's Disease: Treatment
179
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...

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...
