科学领域:
- 神经科学
- 认知心理学
- 临床研究
背景情况:
- 在艾滋病毒感染者 (PLWH) 的认知培训中没有解决认知个体内变异性 (IIV).
- 较大的认知IIV与认知衰退,认知完整性降低和神经病理增加有关.
- 执行失控假说表明执行功能不良会增加认知IIV.
研究的目的:
- 提供可行性临床试验的理由和方案.
- 检查中老年人执行功能培训干预措施.
- 研究提高执行功能以降低认知IIV的潜力.
主要方法:
- 一个双臂,基线/测试后的实验设计,使用120个社区居住的PLWH (40岁以上).

- 评估包括康纳的持续性能测试 (版本3) 和BRACE+认知电池.
主要成果:
- 将评估执行职能干预的可行性和可接受性.
- 将对认知变化进行探索性分析 (目标1).
- 这项研究旨在确定执行功能培训是否可以减少认知IIV.
结论:
- 这项研究测试了一种针对认知IIV的创新干预措施.
- 之前没有研究集中在认知IIV作为干预结果.

Information Processing Approach
154
The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is...

Intellectual Disability
159
Intellectual disability (ID) is a neurodevelopmental condition characterized by deficits in intellectual and adaptive functioning that manifest during the developmental period. This condition encompasses challenges in reasoning, memory, problem-solving, and learning, accompanied by impairments in everyday life skills, such as communication, self-care, and social interactions. Intellectual disability affects approximately 1% of the population in the United States, impacting an estimated 5...

Alzheimer's Disease: Treatment
260
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
267
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,...

Working Memory
444
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this...

Learning Disabilities
271
Learning disabilities are cognitive disorders caused by neurological impairments that affect cognitive functions like language and reading, without indicating overall intellectual or developmental challenges. These disabilities differ from global intellectual or developmental disabilities as they are limited to distinct cognitive functions. Common learning disabilities include dysgraphia, dyslexia, and dyscalculia, each of which impacts unique aspects of learning.
