概括
基因检测是诊断儿童无法解释的全球发育迟缓 (GDD) 的最有效方法. 这项研究发现,基因分析优于代谢测试和MRI,用于识别儿童神经病学中的GDD原因.
科学领域:
- 儿科神经学 儿科神经学
- 临床遗传学 临床遗传学
- 诊断产量评估的诊断产量评估
背景情况:
- 全球发育迟缓 (GDD) 影响高达3%的儿童,由于其多种原因,提出了复杂的诊断挑战.
- 目前GDD的诊断方法多样化,需要研究各种调查方法的有效性.
- 研究基因,代谢和成像研究的诊断产量对于优化无法解释的GDD (UGDD) 的评估至关重要.
研究的目的:
- 评估基因,代谢和磁共振成像 (MRI) 研究在患有不明原因全球发育迟缓 (UGDD) 的儿童中的诊断效用.
- 为了比较不同诊断方式在确定UGDD的病因学在儿科神经病学设置中的有效性.
- 根据临床表现,通过评估哪些测试对揭示GDD的原因最有益,为诊断策略提供信息.
主要方法:
- 追溯观察性研究分析了2019年1月至12月期间被诊断患有UGDD的123名儿童的医疗记录.
- 评估基因检测,代谢实验室检测和MRI的诊断产量,以确定GDD的潜在原因.
- 亚组分析,以确定特定的临床症状是否与特定诊断测试的有效性相关.
主要成果:
- 在47.1% (58/123) 的患者中,无法解释的GDD的基因诊断得到了实现.
- 代谢实验室测试未能在114名测试参与者中识别任何代谢疾病 (0%的诊断收益率).
- 磁共振成像 (MRI) 仅在1.2% (1/81) 的病例中进行诊断,这表明该队列的效用有限.
结论:
- 基因检测显示,与MRI和代谢检测相比,基因检测的诊断产量显著更高,用于确定儿科神经病理门诊患者无法解释的GDD的病因.
- 这些发现支持将基因分析作为诊断工作中未解释的GDD儿童的优先事项.
- 这些证据可以指导临床医生改进儿科GDD的诊断算法,提高效率和诊断准确性.

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...

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.

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...
