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:

  • 老年学是一门学科.
  • 老年医学 老年医学
  • 公共卫生 公共卫生

背景情况:

  • 与社区居住的老年人相比,老年住院护理 (ARC) 居民的跌倒风险明显更高.
  • 在ARC居民中,痴呆和身体障碍加剧了跌倒风险,导致诸如伤害和死亡等严重后果.
  • 目前ARC的防摔策略往往涉及限制居民的流动性,尽管有关门诊活动和跌倒之间的关系的证据尚不清楚.

研究的目的:

  • 为了调查出行活动 (步数) 和老年住院护理居民的跌倒率之间的关联.
  • 探索身体能力和认知障碍对活动和跌倒之间的关系的影响.
  • 通过检查ARC的门诊活动的风险回报平衡,为预防跌倒的策略提供信息.

主要方法:

  • 利用了281名ARC居民在"保持直立"随机对照试验中的数据.
  • 使用加速度计评估每日步数,并在延长的研究时间内监测下跌.
  • 使用短性能物理电池将物理能力分类为中等或低,并使用准Poisson通用线性模型分析协会.

主要成果:

  • 身体能力低的居民的跌倒率高于中等能力的居民 (p=0.001).
  • 增加每日步数与更高的跌倒率相关 (p=0.046),基于身体能力的显著相互作用效应.
  • 适度能力居民显示出步骤和跌倒之间的积极关联,而低能力居民没有;认知障碍与跌倒无关.

结论:

  • 身体能力较强的居民可以实现更多的无摔倒步骤,而跌倒风险的适度增加不会增加受伤风险.
  • 低能力居民具有更高的基线跌倒风险和受伤跌倒发生率,活动水平对他们的风险的影响最小.
  • 这些发现挑战了老年护理的门诊活动的限制,并强调了需要个性化干预的必要性,因为认知障碍与这一群体的跌倒风险没有相关性.
