Neural Tube Defects and Fetal Movement: Key Insights for Expecting Parents

Neural tube defects and fetal movement?

Hello, Doctor.
I would like to inquire about neural tube defects.
Previously, I underwent the fourth marker screening (for Down syndrome), and this index was abnormal, leading to a referral to Mackay Memorial Hospital for an ultrasound on June 21.
The high-level ultrasound has been completed, and the doctors have reported no abnormalities.
The doctor mentioned that if there are minor defects at birth, surgery can be performed.
What examinations or observations should I conduct for my baby at birth to detect any issues early for timely treatment?
Additionally, I have a question regarding fetal movement.
I am currently 23 weeks and 6 days pregnant.
I do feel fetal movements, but they are mild.
During the high-level ultrasound, the doctor mentioned that the baby's position is in the posterior pelvic cavity, making it harder to visualize.
I also find it challenging to perceive the frequency of fetal movements.
Is the frequency and intensity of fetal movements related to the baby's health? A friend of mine, who is two weeks ahead, reports that her baby's movements are frequent and very noticeable, with a pronounced belly.
Should I expect to feel more fetal movements in the coming weeks? Does maternal activity affect fetal movement? Thank you, Doctor.

1.
"What checks should I perform or what conditions should I monitor in my baby at birth to detect and treat issues early?" This is the responsibility of your obstetrician during prenatal care! Of course, due to the limitations of contemporary medical technology, many congenital fetal abnormalities cannot be detected prenatally, regardless of whether early treatment is possible.
2.
"Is the frequency and intensity of fetal movements related to the baby's health?" The frequency of fetal movements is related to the baby's health, but this refers to movements counted via ultrasound.
Self-perceived fetal movements, especially before 22 weeks of pregnancy, are often not very noticeable.
Relying on subjective counts of fetal movements to assess the baby's health can cause significant anxiety for the pregnant woman.
Therefore, it is generally advised not to focus on fetal movement counts before 24 weeks of pregnancy and not to compare movements with others, as the ability to perceive fetal movements varies among pregnant women.
Generally speaking, after 24 weeks of pregnancy, self-perceived fetal movements become more noticeable.
3.
"Does increased physical activity affect fetal movements?" Fetal movements are primarily influenced by fluctuations in the mother's blood sugar levels.
Wishing for the baby's safety and health.

More Info

Neural tube defects (NTDs) are serious congenital conditions that occur when the neural tube, which eventually develops into the brain and spinal cord, fails to close properly during the early stages of fetal development. This can lead to a range of complications, including spina bifida and anencephaly, which can significantly impact a child's health and development. Understanding NTDs is crucial for expecting parents, especially those who may have received abnormal screening results, as it allows for informed decision-making and proactive care.

Understanding Neural Tube Defects
1. Causes and Risk Factors: NTDs can arise from a combination of genetic and environmental factors. Maternal folic acid deficiency is one of the most significant risk factors associated with NTDs. It is recommended that women of childbearing age take folic acid supplements before conception and during early pregnancy to reduce the risk of NTDs. Other factors that may contribute include maternal diabetes, obesity, certain medications, and a family history of NTDs.

2. Diagnosis and Monitoring: If a screening test indicates a potential risk for NTDs, further diagnostic imaging, such as high-resolution ultrasound or MRI, may be recommended. These imaging techniques can help visualize the developing fetus and identify any abnormalities. After birth, healthcare providers will conduct a thorough physical examination of the newborn, checking for signs of NTDs, such as spinal deformities or neurological deficits.

3. Postnatal Care: If a neural tube defect is diagnosed at birth, the treatment plan will depend on the type and severity of the defect. Some conditions may require immediate surgical intervention, while others may be managed with ongoing medical care and therapy. Parents should be vigilant about monitoring their child's development, looking for any signs of motor or cognitive delays, and ensuring regular follow-up appointments with pediatric specialists.

Fetal Movement and Its Implications
1. Understanding Fetal Movement: Fetal movement is an important indicator of a baby's well-being in utero. As pregnancy progresses, mothers typically begin to feel their baby's movements between 18 to 25 weeks. The frequency and intensity of these movements can vary based on several factors, including the baby's position, gestational age, and the mother's activity level.

2. Monitoring Movement: At 23 weeks and 6 days, it is common for fetal movements to be less pronounced, especially if the baby is positioned in a way that makes it harder to feel movements. However, as the pregnancy advances, movements generally become more noticeable. Expecting mothers should monitor their baby's movements and report any significant changes, such as a decrease in activity, to their healthcare provider.

3. Impact of Maternal Activity: Physical activity can influence fetal movement. Engaging in light exercise may stimulate the baby, leading to increased movement. Conversely, if a mother is very active, she may not notice movements as easily. It is essential for mothers to find a balance and ensure they are attentive to their baby's cues.

Conclusion
For expecting parents, understanding neural tube defects and fetal movement is vital for ensuring the health and well-being of their child. Regular prenatal care, including screenings and ultrasounds, can help identify potential issues early on. Parents should also be proactive in monitoring their baby's movements and communicating any concerns with their healthcare provider. By staying informed and engaged, parents can take the necessary steps to support their child's health and development, both before and after birth.
