Pediatric cerebral palsy is also known as pediatric cerebral palsy. It is a permanent but variable motor and postural abnormality based on a non-progressive lesion of the brain that occurs between the mother’s gestation period and the child’s newborn period due to a variety of causes. Pediatric cerebral palsy is a very common pediatric brain disorder that can be caused by many factors. So what exactly are the causes of pediatric paralysis? The immediate causes of cerebral palsy are brain injury and brain developmental defects. According to the time of the injury, it can be simply divided into the mother’s pregnancy, perinatal period, and a short period of time after birth (usually within 1 month). Genetic factors: In recent years, studies have concluded that genetic factors are becoming increasingly important in cerebral palsy. In a comparative study, close relatives with epilepsy, cerebral palsy and 2 of the factors of mental retardation accounted for 65% of cerebral palsy. Fertilized eggs contain DNA genetic material from both parents, which form genes arranged on chromosomes. When chromosomes have numerical or structural aberrations, mutations or inborn metabolic defects, congenital malformations can be produced, which show developmental abnormalities of the individual, and are likely to show symptoms of cerebral palsy. (2) Pregnancy factors of cerebral palsy: (1) The mother suffers from rubella, cytomegalovirus, syphilis and other infections during the embryonic period. The infections invade the fetus through the placenta and produce congenital infections and malformations. (2) Environmental factors during pregnancy: The embryo is susceptible to external environmental factors such as physical, chemical or biological factors during its development in the mother’s uterus, and it is especially sensitive to the embryo within 8 weeks. These factors can cause differentiation and developmental disorders of the embryo, leading to the birth of children with cerebral palsy. (3) Other maternal causes: including maternal abdominal trauma, maternal pre-miscarriage, pre-partum hemorrhage, toxemia of pregnancy, placental causes (placenta previa, placenta praevia, placental necrosis or placental dysfunction), and certain chronic illnesses of pregnant women (such as hypertension, hepatitis, diabetes mellitus, drug addiction, drug allergy, etc.) may all contribute to the occurrence of cerebral palsy in pediatric patients. 3. Neonatal factors of cerebral palsy: Convulsions in the neonatal period are the most important risk factors for cerebral palsy. Birth weight <2500g, the need for special care and the emergence of inhibition in the neonatal period are important factors for cerebral palsy; respiratory distress syndrome in the neonatal period, aspiration pneumonia, sepsis, meningitis, etc. are all significantly associated with cerebral palsy; periventricular leukoaraiosis in preterm infants, asphyxia at birth with hypoxic-ischemic encephalopathy, is an important cause of enduring cerebral damage; immature infants accompanied by asphyxia sometimes Ventricular hemorrhage, periventricular leukomalacia, and other idiosyncratic lesions are present, and these can contribute to the development of cerebral palsy. Injury to the brain during delivery, craniocerebral injury or brain infection in newborns, and cerebrovascular accidents can also lead to cerebral palsy in children. 4.Physical factors: The most common physical teratogens that cause cerebral palsy are: rays, mechanical factors, high temperature, severe cold, microwave, hypoxia and so on. Overall, prenatal causes of cerebral palsy account for about 20%, perinatal and delivery causes account for 70% to 80%, and postnatal causes are 15% to 20%. It is generally believed that asphyxia, immaturity and severe jaundice are the three main causative factors of cerebral palsy. However, in recent years, the proportion of prenatal cerebral palsy has increased due to a decrease in severe jaundice and cerebral palsy caused by immature children. Therefore, parents must pay attention to their children if they have any of the above high-risk factors. Take your child for regular medical checkups and observe your child for signs of abnormality in his/her life. Once any abnormality occurs, the child should go to the child health care or rehabilitation clinic as soon as possible.
