Early diagnosis of cerebral palsy is extremely difficult. Initially, most children with cerebral palsy do not present with specific abnormal symptoms, but their main symptom is developmental delay. In most cases, the newborn has abnormalities at birth, such as prematurity, hypoxia, asphyxia, hyperbilirubinemia, prolonged labor, full-term small sample, and maternal multiple pregnancies. These newborns with high-risk factors require careful follow-up and treatment should be initiated when abnormal muscle tone and motor patterns are present. In most newborns, the condition usually occurs after a “quiet” phase; the quiet phase usually does not require treatment, but treatment must be started as soon as symptoms are suspected. Some newborns may present with uncommon symptoms, but then develop normally. Therefore, it is important to repeatedly examine and rate the development of newborns, especially those under 4 months of age. For infants and children with suspected brain injury, the time interval between examinations should be as short as possible, not more than 3 to 4 weeks after the onset of suspected symptoms. The first year of life is the fastest developmental period in the life span of infants and young children; therefore, early detection, intervention, and treatment are important. Early diagnosis relies heavily on identifying primitive reflexes due to developmental delay versus reflexes due to pathological nature, and it is possible that these individual features may occur together. Primitive reflexes have been defined as patterns of activity that are part of normal, full-term neonates in early life, i.e., reflex actions that are present at birth and will gradually subside several months after birth, whereas pathological reflexes are motor patterns that are not likely to occur during normal neonatal development. Cerebral palsy is a non-continuously progressive outcome due to a central nervous disorder with lesions in the brain, involving the extremities, with a variety of presentations and symptoms occurring in infancy. Therefore, it is necessary to screen for cerebral palsy before it appears in a specific form.
