Can congenital hypothyroidism lead to brain development issues?

Hello,

Welcome to icliniq.com.

I am here to guide you with your query.

I just read your query about your daughter's congenital hypothyroidism. I am sorry and I can empathize with you but at the same time, I would like to say that timely diagnosis in an infant for congenital hypothyroidism is very essential and your daughter has been diagnosed at an early stage before any damage pertaining to growth and brain development could occur. Congenital hypothyroidism occurs due to an inborn error in metabolism and can manifest at any time after birth. Yes, there should have been a screening done immediately after birth. Your hypothyroidism has only a transient effect on the developing fetus if you are already on treatment. Her weight is increasing so that is a good sign. As long as she is on treatment and given the correct dose, your child can grow normally without any brain development issues. Complications occur when the child goes undiagnosed. So, please be positive.

Your prime responsibility henceforth should be watching her growth and development. Just monitor the following signs and symptoms at all times.

1. Whether she is active or not.
2. Large anterior fontanelle.
3. Whether she is feeding well and gaining weight.
4. Whether her growth is poor or her stature is small.
5. Presence of jaundice.
6. Decreased stooling or constipation.
7. Hypotonia.
8. Hoarse cry.

T4 (total or free T4) and TSH (thyroid stimulating hormone) should be repeated four to six weeks after initiation of therapy, then after every one to three months during the first year of life, and after every two to four months during the second and third year of life.

I hope your queries got resolved. Do get back if you have any further queries.

Thank you.
