If the mother has intellectual disability, she wants to know the cost of routine intelligence tests and the normal development of the fetus. During pregnancy, it is necessary to carefully observe whether the fetus has any major malformations or genetic diseases, but it is impossible to predict the level of intelligence. A Down syndrome screening can be conducted between 15-20 weeks of pregnancy to understand the growth and development of the fetus. Patients with intellectual disability should actively seek treatment to stabilize their condition and increase the chances of recovery.
