Definition of high-risk infant: During the fetal or neonatal period, the physical and mental development of some fetuses or newborns, especially brain development, is affected by risk factors, and such newborns are called high-risk infants. Potential risks for high-risk infants: The vast majority of high-risk infants grow and develop in a completely healthy manner, and brain damage occurs in about 8-9%. Due to various risk factors, brain damage may occur as a result of poor brain development, hypoxic-ischemic injury or birth injury, which may lead to cerebral palsy, mental retardation, epilepsy, behavioral deviation, and abnormal mental development, etc. Such damage not only harms physical and mental health, but is also a major cause of pediatric disability. The purpose of screening for high-risk children is to promote the healthy growth of high-risk children and to reduce the occurrence of diseases and disabilities due to brain injury.
