Parents expect their children to be safe, healthy and happy! This is also the simplest wish of parents, they can be less smart, but must be healthy; they can be less cute, but must be happy. So, do moms and dads know what diseases can lead to impaired intelligence in children? Let’s find out together! 1, neonatal bilirubin encephalopathy If young parents do not know what is neonatal bilirubin encephalopathy, then the other common name “jaundice” must be very familiar. Neonatal jaundice usually occurs from the second to the seventh day after birth and is caused by high concentrations of bilirubin in the newborn’s blood that cannot cross the blood-brain barrier into the brain, resulting in nerve cell toxicity, which can directly affect the function and development of brain cells and lead to intellectual failure. Neonatal jaundice will disappear naturally under normal circumstances, but if it is severe, light must be administered to ensure early recovery, otherwise it is detrimental to the newborn’s intelligence. 2, septic meningitis At the mention of septic meningitis, many parents will shudder in their hearts because it is a neonatal disease with a high mortality rate. Bacteria and toxins invade the brain cell tissue of newborns, resulting in severe impairment of brain cell function, rapid onset, small cure rate, and in many cases, neonatal death. In recent years, this type of disease has decreased in China, but it does not mean that it is not present, and it is very frightening when it does occur. Generally newborns are born with mandatory vaccination to reduce the chance of infection. 3, neonatal intracranial hemorrhage neonatal intracranial hemorrhage is generally caused by trauma caused by external forces, once the intracranial pressure increases will lead to blood vessel rupture bleeding, which makes the bleeding part of the brain cells blood circulation is blocked, resulting in the corresponding brain cell necrosis, directly affecting the child’s intellectual development, is a high risk of the child’s intellectual development of the disease. Although the incidence of intracranial hemorrhage in newborns is not high, it is one of the important causes of neonatal intellectual impairment that parents need to pay more attention to and should not be ignored. 4, ischemic-hypoxic encephalopathy When it comes to neonatal ischemic-hypoxic encephalopathy, it is easy to even think of difficult fetal delivery in the mother’s womb without points of normal delivery, resulting in hemorrhage and hypoxia. During delivery, if the fetus suffers from hypoxic asphyxia, the blood and oxygen supply to the brain is terminated, resulting in brain cell damage and mental retardation. Depending on the duration of hypoxia causes different degrees of damage, some are only mild and can be improved by training later in life, while some severe cases are impossible to improve later in life. When a woman has a difficult birth, she should immediately take a caesarean section, rather than waiting until both mother and child are in danger before thinking of a caesarean section.
