I have to ask this because, since I was born in 1955 with CHT , It took nearly four months to diagnose and treat even though there was heavy neonatal jaundice for nearly a week, it still didn't get pinned down to this condition and I was dicharged at three weeks old, only to have to be readmitted at 15 weeks with blue tinged skin around nose and mouth..
I've never met anyone to have this condition as it is rare. There's no point comparing my case with someone's who had benefit of new born screening as the changes in my brain in the period without treatment.
This resulted in damage to sight and other more subtle symptoms, also slow at school. What is the point in treating this condition with synthetic thyroxine, without varying the dose at key life changes, since the action of the normal thyroid is not only to make the hormone, but to direct it also?
The family Doctor i had, didn't take any blood tests in all my school years and neither did the paediatrician in the regular visits i had to make in the same years until sixteen. Most people including family members think these pills actually do the same job as if i had normal thyroid function, so they make no allowances as if the condition was cured. Clearly throid tablets were no subsatitute for me.
