What causes the onset of spastic cerebral palsy in children? The incidence of pediatric cerebral palsy is increasing, especially the incidence of spastic cerebral palsy. The occurrence of spastic cerebral palsy endangers the physical and mental health of children and has become a concern for parents. So, what causes the onset of spastic cerebral palsy in children? The following is a detailed description of the causes of spastic cerebral palsy: 1. The most common causes of spastic cerebral palsy in the postnatal period are encephalitis, meningitis, trauma, vascular accidents and hypoxia. In the acute phase of encephalitis, motor function deficits progress as the lesion intensifies. Later in the acute phase, motor dysfunction is triggered by increased scarring lesions in the brain tissue. Second, spastic cerebral palsy prenatal congenital type defects of the brain are often due to rubella or other viral type infections in the mother during early gestation, during the first trimester of pregnancy. These children often have other congenital type abnormalities as well, such as cataracts, congenital type heart defects (ventricular septal defects), deafness, and unresponsiveness. Fetal nuclear erythrocytosis used to be a common prenatal cause. Third, the most common cause of spastic cerebral palsy at delivery is preterm birth. If the birth weight is below 2268g, cerebral palsy has a higher chance of occurrence. Others are usually due to trauma during delivery or hypoxia due to incorrect application of forceps, obstructed labor or prolonged labor.
