概括
患有亚历山大病 (AxD) 的儿童表现出不同的语言技能. 大脑AxD患者有显著的缺陷,而中间和脊椎亚型的表现更好,表明疾病亚型影响沟通能力.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 儿科神经学 儿科神经学
背景情况:
- 亚历山大病 (AxD) 是一种罕见的遗传性白脑病,其特点是质纤维酸蛋白 (GFAP) 基因的突变.
- 在神经退行性疾病中,语言发育往往受到影响,但AxD亚型中的特定模式尚未确定.
研究的目的:
- 研究被诊断患有亚历山大病 (AxD) 的儿童的语言技能.
- 为了确定特定的AxD疾病亚型 (大脑,中级,球脊) 或患者年龄是否影响语言表现.
- 为了将语言评估得分与疾病进展标志物相关联.
主要方法:
- 有82名确诊的AxD (GFAP测试) 的参与者被分为大脑 (n=56),中间 (n=9) 和球脊 (n=17) 类型.
- 语言能力使用学前语言表第五版 (PLS-5),临床语言基础评估第五版 (CELF-5) 和皮博迪图片词汇测试第四版 (PPVT-4) 进行评估.
- 通信功能分类系统 (CFCS) 评估了功能通信;统计分析包括Wilcoxon签名等级和Kruskal-Wallis测试.
主要成果:
- 平均PLS-5总语言得分 (TLS) 是70.10 (SD=17.62).
- 根据表型,CELF-5核心语言分数 (CLS) 有显著差异:大脑 (M=57.22),中间 (M=92.50) 和球脊 (M=91.56).
- 大脑AxD患者在PLS-5 TLS和第一次诊断时的年龄之间显示出负相关性 (rho=-.367,p=.017). CELF-5 CLS和PPVT-4得分与首次神经症状出现的年龄相关 (rho=.576,p=.003和rho=.336,p=.011).

Language and Cognition
696
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Higher Mental Functions of the Brain: Language
3.4K
Language is a system of communication that allows the expression of thoughts, ideas, and feelings. The brain processes language in both hemispheres.
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Learning Disabilities
554
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.

Lateralization
949
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

Language Development
810
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Health Literacy
5.2K
Health literacy is an individual's or a community's capacity to comprehend, receive, read, and use relevant healthcare information and services. The World Health Organization (WHO, 2018) defines health literacy as the cognitive and social skills that determine the ability of individuals to gain access to, understand, and use information in ways that promote and maintain good health. As a result, the WHO helps individuals manage long-term health concerns, participate in preventative...
