概括
中期至晚期早产 (MLP) 儿童的新生儿大脑体积与学龄执行功能 (EF) 的联系较弱. 需要进一步的研究,以确定其他预测EF在这个未经研究的人群.
科学领域:
- 神经科学是一个神经科学.
- 发育儿科 发育儿科
- 医疗成像医学成像
背景情况:
- 新生儿大脑体积较大与中晚期早产 (MLP) 婴儿的更好的认知发育相关.
- 这种关联在学龄执行功能 (EF) 中的持久性在MLP人群中仍然基本未被探索.
研究的目的:
- 调查新生儿大脑体积与9岁时执行功能 (EF) 在中晚早产 (MLP) 儿童中之间的关联.
- 为了确定新生儿大脑结构是否预测这个特定的早产组的学龄EF结果.
主要方法:
- 脑磁共振成像 (MRI) 在168名MLP婴儿的术语相当年龄进行.
- 执行功能 (EF) 在9岁时对159名儿童进行评估,使用注意力控制,认知灵活性,目标设定和行为EF的措施.
- 线性回归模型估计了大脑体积和EF子域之间的关联,分析按子组分层.
主要成果:
- 在新生儿大脑体积和学龄EF之间观察到很少有显著的关联.
- 在较大的白质量和更好的目标设定之间发现了小的积极关联 (p=0.01).
- 亚组分析得出类似的,有限的关联.
结论:
- 新生儿大脑容量并不是学龄执行功能 (EF) 的强有力的预测指标,在中期到晚期早产 (MLP) 的儿童中.

01:30Biological Influences on Intelligence
219
Intelligence is often thought to be linked to brain size, but the relationship is more complex than that. While brain size does correlate modestly with some abilities, like verbal skills, the connection is weaker for others, such as spatial reasoning. Other factors, like brain structure, also play crucial roles. For instance, despite Einstein's smaller-than-average brain, his parietal cortex, which is involved in spatial reasoning, was 15% wider, suggesting that neural density might matter...

01:30Information Processing Approach
161
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...

01:30Attention-Deficit/Hyperactivity Disorder
294
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
