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:

  • 老年学和人工智能的人工智能
  • 数字健康和传感器技术
  • 医疗保健中的机器学习

背景情况:

  • 照顾者负担评估传统上依赖于主观的自我报告,缺乏客观的家庭活动数据.
  • 之前的研究证实了在长时间内收集家庭传感器数据的可行性和可接受性.
  • 确定与痴呆症患者的照顾者负担相关的特定家庭活动仍然是一个悬而未决的问题.

研究的目的:

  • 利用家庭传感器数据开发"数字签名",以量化护理人员负担.
  • 确定客观的家庭活动模式,与不同级别的护理伙伴负担相关.
  • 探索机器学习对分析传感器数据的实用性,以预测护理人员负担.

主要方法:

  • 临床和家庭运动传感器数据的分析来自对二的纵向研究 (护理伙伴和轻度认知障碍或痴呆症的个人).
  • 机器学习模型,包括独立组件分析 (ICA) 和决策树,用于分析传感器特征 (例如,房间占用,运动模式).
  • 使用Zarit负担访谈简单表格 (ZBI-12) 每周测量护理合作伙伴负担;SHAP值确定了关键预测特征.
