概括
患有22q11.2删除综合征 (22q11.2DS) 的个体可以按认知功能分组. 在22q11.2DS下降的认知能力与更多的精神问题有关,这表明认知影响风险.
科学领域:
- 遗传学 是一个遗传学.
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
背景情况:
- 22q11.2删除综合征 (22q11.2DS) 带来了重大的精神疾病挑战.
- 在22q11.2DS的表型变异使识别高风险个体变得复杂.
- 了解认知特征可能有助于心理疾病风险分层.
研究的目的:
- 调查22q11.2DS个体是否可以根据认知障碍严重程度分组.
- 确定这些认知子组是否在精神分裂症的多基因风险上有所不同.
- 在22q11.2DS.DS.中探索认知功能和精神病症之间的关系.
主要方法:
- 全国范围内的生物库队列183个22q11.2DS (10-30岁) 个体的横截面分析.
- 对终身精神病诊断和精神分裂症多基因风险评分的评估.
- 在一个嵌套子组 (n=28) 中进行综合认知评估和精神症状评估,使用无监督的等级集群分析.
主要成果:
- 两个不同的认知子组出现了:低认知功能 (LF) 和高认知功能 (HF).
- 在LF组显示显着较低的全球认知得分和更高的负面精神症状.
- 与LF组相比,HF组的当前精神疾病发病率较低.
结论:
- 认知功能水平可以将22q11.2DS个体区分为临床相关的子组.
- 认知障碍的严重程度与22q11.2DS.DS中的精神病症状严重程度有关.
- 认知功能可能成为22q11.2DS.DS中精神病风险的有价值的生物标志物.

Intellectual Disability
48
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...

Language and Cognition
340
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.

Autism Spectrum Disorder
79
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Genomic Imprinting and Inheritance
34.3K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

Learning Disabilities
93
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.
