1. From the developmental characteristics of the brain and nervous system. The earlier the discovery, the greater the plasticity of the brain and nervous system, the better the treatment effect. Research shows that the newborn brain weighs 300-340 grams and reaches 800 grams 6 months after birth, and the development of the brain and nervous system reaches 60% by the age of 3 and 90% by the age of 6. 2.Treatment can avoid lifelong disability caused by the formation of bad posture and limb deformity. 3.The formation of character and thinking ability is mainly in preschool age. Especially, the earlier the rehabilitation of educational psychology, the better it is for the overall growth of the affected child. What are the diagnostic criteria of cerebral palsy? The diagnosis of cerebral palsy mainly relies on medical history and physical examination, EEG, CT and MRI, etc. CT and MRI can understand whether there is any abnormality in the cranial structure, which may be helpful to investigate the cause of cerebral palsy and judge the prognosis, but they cannot confirm or deny the diagnosis, and EEG can understand whether there is a combination of epilepsy, which is a reference value for treatment. The diagnosis of cerebral palsy should meet the following conditions: (1) the causative factor occurred during maternal pregnancy, perinatal period or neonatal period; (2) the central palsy appeared in infancy; (3) except for the central palsy caused by progressive diseases (metabolic disease, tumor, etc.); (4) except for the transient motor development delay in normal children.
