Dementia

482
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual....

Alzheimer's Disease: Treatment

744
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...

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...

Parkinson's Disease: Overview

1.7K
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...

科学领域:

  • 神经科学是一个神经科学.
  • 认知科学 认知科学
  • 老年学是一门学科.

背景情况:

  • 传统的笔纸神经心理评估缺乏检测早期阿尔茨海默病 (AD) 早期微妙认知变化的灵敏度.
  • 现有的方法在短期内监测认知表现的能力有限,阻碍了早期干预策略.

研究的目的:

  • 评估频繁,远程和无监督的数字认知评估在捕捉早期AD的短期认知衰退中的有效性.
  • 将数字评估的灵敏度与传统的面对面测试进行比较,以检测轻度认知障碍 (MCI) 患者的认知变化.

主要方法:

  • 在202名参与者 (52-85岁) 中研究了情节性记忆轨迹,使用至少30周的自我管理远程数字测试.
  • 采用线性混合建模来分析认知状态 (认知无障碍与MCI) 以及其与研究持续时间的相互作用.
  • 根据粉样蛋白-β (Aβ) 负担对MCI参与者进行了分层分类,并检查了远程和面对面评估之间的相关性.

主要成果:

  • 与没有认知障碍的个人相比,患有MCI的参与者在关联记忆,记忆精度和基于熟悉性的记忆任务方面表现出缺陷.
  • 在所有MCI患者中观察到熟悉性依赖记忆的短期下降;特定任务也检测出高Aβ负担的MCI患者的下降.
  • 远程评估的变化与长期面对面评估的变化相关,而面对面的测试对MCI的短期认知变化不敏感.

结论:

  • 频繁的远程认知测试提供了一种可行的和敏感的方法来捕捉微妙的,短期的认知衰退.
  • 数字认知评估代表了在AD等神经退行性疾病的早期阶段监测认知健康的有希望的进步.
  • 这种方法有可能改善认知障碍的早期检测和管理.
