概括

产前葡萄皮质激素 (GC) 暴露不会影响青少年的智商或自主神经系统 (ANS) 活动. 然而,观察到前额电皮活动减少,这表明潜在的脑成熟障碍.

科学领域:

发育神经科学的发展神经科学.
内分泌学在内分泌学.
儿科医学儿科医学儿科医学

背景情况:

产前暴露于超生理性葡萄皮质激素 (GCs) 可能会导致持久的发育变化.
以前的研究将产前GC预防与儿童的认知和电生理学变化联系在一起.
这项研究调查了这些影响在青春期持续的情况.

研究的目的:

评估产前GC暴露对青少年认知功能,注意力和生理活动的长期影响.
为了确定以前观察到的认知和电生理学变化是否持续到青春期.

主要方法:

一项前性观察性随访研究,对青少年 (14-15岁) 在子宫内暴露于贝塔梅他,与对照组进行了对照.
评估了认知表现 (IQ),ADHD症状,代谢标志物和电皮质 (EEG) 活动.
在压力范式中测量了下丘脑-垂体-上腺轴 (HPAA) 和自主神经系统 (ANS) 活动.

主要成果:

两组之间智商,ADHD症状或代谢标志物没有显著差异.
在整体或压力诱导的HPAA和ANS活动中没有显著差异.
贝塔梅他组显著减少了前额电皮活动 (光谱边缘频率).

结论:

产前GC暴露与青少年智商或ANS活动的差异无关.
降低前额电皮质活动可能表明皮质/皮质下大脑成熟的改变.
这些发现需要谨慎解释,因为样本大小和潜在的混;需要进一步的研究.

Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

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....

Teratogenicity

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
