Early symptoms of pediatric cerebral palsy: Cerebral palsy is a syndrome of non-progressive brain damage caused by various reasons in the child before birth to one month after birth. The causes are complex and varied, mainly focusing on three aspects: first, prenatal factors, including intrauterine infection, intrauterine growth retardation, trauma during pregnancy, multiple pregnancies, etc.; second, intrapartum factors, mainly prematurity and obstructed labor; third, postpartum factors, including neonatal shock, cranial injury and epileptic convulsions caused by hyperbilirubinemia, blood loss, infection, etc., and genetic factors. Among these causes, prematurity and low birth weight are the most important factors causing cerebral palsy, and the shorter the gestation period and the lower the birth weight, the higher the prevalence of cerebral palsy. The early symptoms of cerebral palsy in children are very obvious, and parents can detect the signs of cerebral palsy if they observe carefully. In the neonatal period, the child shows no interest in everything around him or her, is very unresponsive, has significantly reduced movements, and even has poor sucking ability, often choking on milk. If a doctor is asked to examine the child, he or she will also find that some innate reflexes such as the foraging reflex, grip reflex, and hug reflex are diminished or do not appear at all. In infancy, the child shows signs of delayed intellectual-motor development, such as difficulty in thigh abduction, knee flexion and difficulty in straightening, straightening and inward movement of the legs when held upright, crossed legs in a scissors shape, flexion of the elbow and wrist joints of the upper limbs, and frequent clenching of the hands with the thumbs inward. There is little active movement, and after 5 months of age, the baby still cannot actively reach out to grasp things he likes, or always uses one hand to grasp. Abnormal reflexes appear, i.e. some primitive reflexes are delayed to disappear, while normal protective reflexes are weakened or do not appear, and some pathological reflexes may also appear. Children in early childhood already have many behavioral abilities, and any abnormalities are easily detected. The child may have physical movement disorders, cannot walk or have abnormal walking posture, such as toe landing, scissor gait, limping, and inability to squat, etc. The child may have inflexible hand movements, cannot fetch things with his hands or always use one hand to reach things; he may have intellectual backwardness, language development backwardness or language disorders, or have abnormal vision or hearing loss. Cognitive and behavioral abnormalities, such as excitement and hyperactivity or isolation and vulnerability, may occur. Some children with cerebral palsy develop tardive dyskinesia, ataxia, hypotonia and tonicity, tremor, etc.
