Cerebral palsy is a syndrome caused by non-progressive brain injury during the developmental period from prenatal to 1 month after birth, mainly manifesting as central motor disorders and postural abnormalities. According to Guangzhou Daily, many foreign studies on the causes of cerebral palsy have been conducted recently, and the results show that birth asphyxia is not a common cause of cerebral palsy, and most of the children delivered from high-risk pregnancies have normal nervous systems. Experts point out that the use of ovulation-promoting drugs in the treatment of infertility has led to a significant increase in the rate of multiple pregnancies in recent years, and the relationship between multiple pregnancies and cerebral palsy is drawing increasing attention from the medical community. The incidence of preterm birth and low birth weight is significantly higher in multiples than in singletons. Experts believe that the reasons for this may include: multiple pregnancies are likely to lead to a relative lack of placental function; interfetal transfusion syndrome can cause fetal anemia, low birth weight, heart failure, etc.; and multiple pregnancies are also prone to combined amniotic fluid and premature rupture of membranes. Reminder 2: Be alert to trauma during pregnancy Some studies have shown that trauma during pregnancy mostly occurs in late pregnancy, and trauma during pregnancy is closely related to the onset of cerebral palsy in mothers. In addition, trauma during pregnancy can cause reduced placental blood flow, placental thrombosis and premature rupture of fetal membranes, and even a small trauma can cause fetal death or premature birth. Reminder 3: Pregnant women’s cardiopulmonary disorders Cardiovascular and respiratory dysfunction can lead to cerebral ischemia in preterm infants, such as ductus arteriosus, hypotension, pneumothorax, bronchopulmonary dysplasia, respiratory distress syndrome, etc. Reminder 4: Drug abuse by mothers can lead to abnormal fetal neurological development, such as intrauterine growth retardation and attention deficit in fetuses of drug-addicted mothers. Reminder 5: Radiation can cause cerebral palsy Exposure of pregnant women to radiation from atomic bomb blasts can lead to cerebral palsy, cerebellar malformations and mental retardation.
