Thyroid hormones play an important role in fetal brain development - New scientific study claims that when these hormones are low in the mother's body during pregnancy, the child is at increased risk of developing ADHD
Low thyroid hormone levels during pregnancy can lead to partial growth Attention Deficit / Hyperactivity Disorder (ADHD) to the children, according to new research published in American Journal of Perinatology.
The study found that the children γυναικών με χαμηλά επίπεδα της ορμόνης του θυρεοειδούς during the first trimester of pregnancy they had 28% increased risk of being diagnosed with ADHD, for the challenge of which they are held responsible, including, and some genes that are regulated by thyroid hormones
"THE thyroid gland is extremely important in pregnancy and can have long-term consequences. These findings underscore the great need for integrated prenatal care», points out the lead author of the study and associate professor at New York University Winthrop Hospital.
To conduct the study, the researchers almost examined the records 330.009 children born between 2000-2016 and relevant information was collected up to their age 17 years.
As emerged from the results, almost 17.000 children were diagnosed with ADHD, while approximately 10.000 Expectant mothers were then diagnosed with low thyroid hormone levels during pregnancy.
In addition to the generally increased rate of ADHD in children born to mothers with low hormone levels of the thyroid, scientists also found a significant racial difference. The Spanish-speaking children, whose mothers had low levels of thyroid hormones during pregnancy, presented increased by 45% risk for ADHD, συγκριτικά με τον κατά 22% increased risk for other children.
Experts say it was not clear from the study data why the effect of low thyroid hormone levels was stronger for Hispanic children., emphasizing, in fact, how this effect was more significant in boys than,what about the girls.
It is noted, yet, that the study found only a correlation between thyroid levels and ADHD and no cause-effect association. In this context, scientists emphasize its importance optimal control of women's health both before and during pregnancy, to show if testing and subsequent treatment for low thyroid hormone levels can make the difference in ADHD rates.
