概括
帕金森病患者无动于衷的阿米洛伊德β沉积较高,认知能力下降更快. 粉样蛋白负担,而不是冷漠,预测了三年内认知转换.
科学领域:
- 神经科学是一个神经科学.
- 神经学 神经学
- 老年学是一门学科.
背景情况:
- 漠不关心,目标导向活动的减少,是帕金森病 (PD) 的非运动症状.
- 无动于衷和β-粉样蛋白 (Aβ) 沉积是PD患者痴呆的潜在危险因素.
研究的目的:
- 为了调查PD无情患者是否与非无情患者相比表现出更高的Aβ负担.
- 确定冷漠和Aβ负担对痴呆症进展速度的影响.
主要方法:
- 在48名PD患者 (20名无动于衷,28名无动于衷) 的观测横截面和纵向研究中.
- 评估包括临床评估,认知测试和Aβ沉积的[18F]-甲醇PET扫描.
- 3年后重复神经心理评估;逻辑回归和线性混合效应模型分析了转化和认知轨迹.
主要成果:
- 无情的PD患者表现出较差的认知表现和显著更高的Aβ负担,特别是在额叶和皮层.
- 在3年内,转化到更糟糕的认知状态的比率在冷漠患者 (47.4%) 和非冷漠患者 (12.0%) 中更高.
- 后勤回归确定了Aβ负担,但不是冷漠本身,作为3年认知转换的重要预测因素.
结论:
- 无动于衷的PD患者表现出Aβ负担增加和认知恶化加速.
- 粉样蛋白沉积是影响帕金森病认知衰退和痴呆症进展的关键因素.

Parkinson's Disease: Overview
1.8K
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...

Alzheimer's Disease: Overview
1.6K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

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.

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.

Alzheimer's Disease: Treatment

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...
