Drinking during pregnancy will change the baby’s brain structure

Edit Recommendation: A new magnetic resonance study shows that drinking alcohol during pregnancy, even a small amount of moderate drinking, will change the baby’s brain structure and delay brain development.

A new nuclear magnetic resonance study shows that drinking during pregnancy, even a small amount of moderate drinking, will change the baby’s brain structure and delay brain development.The research results will be announced at the annual meeting of the North American Radiation Society (RSNA) next week.

"Fetal MRI is a highly professional and safe way of examination. It allows us to accurately explain the maturity of the fetal brain." The senior author of the research, the Biomedical Imaging and Image Guidance Department of the Vienna Medical University in Austria, Austria’s Vienna Medical UniversityDr. Gregor Kasprian Medical Ph.D. in radiology said.

During pregnancy, drinking can expose the fetus to a set of diseases called fetal alcoholic spectral disorder.Babies with fetal wine essence at birth may develop into learning disabilities, behavioral problems or words and language delays.

"Unfortunately, many pregnant women do not realize the impact of alcohol on the fetus during pregnancy," said Patric Kienast, a doctoral student in the Department of neurotating and muscle radiology of Vienna Medical University and muscle radiology division, said: Patric Kienast said:"Therefore, we not only have the responsibility to study, but also actively educate the impact of public alcohol on the fetus."

In this study, the researchers analyzed the nuclear magnetic resonance examination of 24 pre -produced fetuses.During the MRI examination, the pregnancy period is between 22 and 36 weeks.Alcohol exposure is determined by anonymous investigation of the mother.The questionnaire uses the pregnancy risk assessment monitoring system (PRAMS), a disease control and prevention center and the monitoring items of the health department, and the T-ACE screening tool. The four problems of a measurement tool determine the risk drinking.

Among the fetal exposed fetuses, the total mature score (FTMS) of the fetus is significantly lower than the age -matching control group, and the right temporal groove (STS) is shallow.STS is related to social cognition, audiovisual integration and language perception.

"We find that the temporal brain region and STS have changed the greatest," said Dr. Kasprian. "We know that the formation of this area, especially STS, has a great impact on the development of the language in childhood."

Even under the exposure of low -level alcohol, the fetal brain has changed.

Dr. Kienast said: "17 of the 24 mothers have a relatively low frequency of drinking, and the average drinking is less than one cup per week." "Nevertheless, we can still detect significant changes in these fetuses through MRI before childbirth."

Three mothers drink one to three cups a week, and two mothers drink four to six cups a week.A mother drinks 14 cups or more drinks per week.The six mothers also reported that at least one alcoholism during pregnancy (more than 4 times).

According to researchers, the delay of the development of the fetal brain may be related to the delay of the formation of the culcinoscopy and the rotation of the ear and pillow leaf.

The formation process of myelin sheath is critical to the function of the brain and nervous system.Protection of nerve cells for marrow phospholipids allows them to pass information faster.The important milestone of the baby, such as turning, crawling, and language treatment are directly related to the formation of the culcinoscopy.

The brain refers to the formation of the cerebral cortex folds.This folding expands the leather surface area of the limited space in the skull, thereby improving cognitive ability.When the rotation weakens, the function is reduced.

"Pregnant women should avoid drinking strictly," said Dr. Kienast. "As we showed in research, even a small amount of alcohol intake can cause the structure of brain development and delay of brain maturity."

It is unclear how these structure changes will affect the brain development after the birth of these babies.

It is difficult to cognition and behavior that may occur during childhood. "
