概括

这项研究开发了一种使用自然语言处理 (NLP) 来检测巴西葡萄牙语临床笔记中的妄想症状的深度学习模型,显著提高了电子健康记录 (EHR) 的识别准确性. 人工智能模型有助于识别痴呆症,这是老年人常见的疾病.

科学领域:

人工智能在医学中的应用
自然语言处理 (NLP) 用于临床文本分析
老年医学和 Delirium 检测

背景情况:

痴呆症在住院的老年人中很普遍,往往导致不良结果.
由于临床和系统性挑战, Delirium 的诊断不足是常见的.
需要改进的方法来识别电子健康记录 (EHR) 中的妄想症状.

研究的目的:

开发和评估一个深度学习NLP模型用于妄想症状识别.
训练模型使用来自EHR的巴西葡萄牙语临床笔记.
为了促进住院老年人痴呆症的检测和识别.

主要方法:

从500次老年人住院治疗中提取并注释的临床笔记.
使用BERTimbau深度学习模型和随机森林方法进行比较.
开发了CAM-BERT框架,以使检测到的症状与混评估方法 (CAM) 标准保持一致.

主要成果:

伯廷博模型取得了77%的F1宏积分,高于基线的39%.
高F1分数 (约90%) 获得了识别混乱和无组织思维.
在CAM-BERT框架中,通过专家审查,F1宏分数达到83%的良好一致性 (科恩的卡帕=0.72).

结论:

人工智能,特别是NLP,显示出支持妄想识别的巨大潜力.
开发的模型在非英语临床环境中有效,使用巴西葡萄牙语笔记.
为了更广泛的适用性,建议在不同的医疗保健环境中进行进一步的验证.

Alzheimer's Disease: Treatment

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...

Cognitive Development During Adulthood

Cognitive Development During Adulthood

Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
