Functions of Thyroid Hormones01:18

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...
Environmental Influences on Intelligence01:29

Environmental Influences on Intelligence

Despite the strong genetic influence on traits like intelligence, environmental factors significantly shape outcomes. For example, while over 90% of height variation is due to genetic differences, environmental factors such as nutrition also have a notable impact. Similarly, for intelligence, changes in a child's surroundings can significantly alter their IQ. Research shows that enriched environments boost children's academic success and help them develop key cognitive skills. Children from...
Regression Toward the Mean01:52

Regression Toward the Mean

Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when researchers try to extrapolate results...
Information Processing Approach01:30

Information Processing Approach

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 also...
Biological Influences on Intelligence01:30

Biological Influences on Intelligence

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 more...
Synthesis and Regulation of Thyroid Hormones01:20

Synthesis and Regulation of Thyroid Hormones

Low blood levels of the thyroid hormones — triiodothyronine (T3) and thyroxine (T4) — signal the hypothalamus to release the thyrotropin-releasing hormone (TRH). TRH then reaches the pituitary gland and stimulates the release of thyroid-stimulating hormone(TSH) into the bloodstream.
Upon reaching the thyroid gland, TSH stimulates the follicular cells' active uptake of iodide ions from the blood. The ions diffuse to the apical surface of the cells and are oxidized to iodine. The iodine is then...

Area of Science:

  • Endocrinology
  • Developmental Psychology
  • Public Health

Background:

  • Thyroid hormones are crucial for fetal neurodevelopment.
  • Limited population data exist on maternal thyroid function and child cognition.

Purpose of the Study:

  • To investigate the association between maternal thyroid hormone levels in early pregnancy and children's cognitive development.
  • To examine the impact of maternal hypothyroxinemia and thyroid-stimulating hormone (TSH) and free thyroxine (FT4) levels on cognitive outcomes.

Main Methods:

  • Population-based cohort study in The Netherlands with 3659 mother-child pairs.
  • Maternal thyroid function (TSH, FT4) assessed at 13 weeks gestation.
  • Children's cognitive functioning (expressive vocabulary, verbal and nonverbal skills) assessed at 18 and 30 months.

Main Results:

  • Maternal TSH levels showed no association with cognitive outcomes.
  • Increased maternal FT4 levels were linked to a reduced risk of expressive language delay at 30 months.
  • Both mild and severe maternal hypothyroxinemia were associated with increased risk of expressive language delay.
  • Severe maternal hypothyroxinemia also predicted a higher risk of nonverbal cognitive delay.

Conclusions:

  • Maternal hypothyroxinemia during early pregnancy is a significant risk factor for cognitive delay in children.
  • These findings underscore the importance of maternal thyroid health for child neurodevelopment.
