yes you are right. hypothyroidism can affect the fetal brain development especially in early pregnancy. thyroid hormone is normally very important for many functions of the body. it helps in the early development of the fetus. the brain is one of the parts of early organ development. in early pregnancy fetus mainly depends on mother's thyroid level because fetus itself cannot produce up to around 11 to 12 weeks (three months). there is no data available whether you have taken treatment early and adequately. but yes there is data that hypothyroidism can affect brain development and function in baby permanently and whatever damage occurs is irreversible. if you are taking thyroxine (levothyroxine) 50 mg and the level is this high then you need to increase the dose. and if you have started treatment just now then continue and repeat according to the doctor. as far as termination is concerned that is totally the couple's call. if you are prepared to take care of a mentally handicapped baby and related problems for the rest of life then you can definitely continue. if you are not prepared for that then you can go for termination. first control thyroid level and then try for pregnancy after you have a normal thyroid level. you will have to take tablets for hypothyroidism for the rest of your life. only dose adjustment will be required time to time according to the thyroid level. so the last choice is yours. you know what can happen. if you are ready for it then go for it and do whatever you have to minimize that. get treated for hypothyroidism more aggressively and control as early as possible. for further information consult an obstetrician and gynaecologist online --> <link>
