Cerebral palsy is a condition in which the brain functions abnormally, causing motor and developmental disorders throughout the body. Neurologists, especially pediatric neurologists, can diagnose the condition when the child is born. The main areas of judgment may be muscle tone, body flexibility, and what we call basic reflexes, and the newborn may also have nystagmus, which is the vibration of the eyeballs, which is different from normal children. Therefore, if we add the medical history, such as intrauterine asphyxia or amniotic fluid contamination, Apgar score, which is the whole score of respiration, heart rate, muscle tone and cry at the time of birth, as well as physical examination after birth to see if there is nystagmus, whether there is any other abnormal gaze of the eyes, whether there is stiffness of muscle tone, movement, and whether there is normal reflexes, it is possible to make a preliminary judgment on whether a child may have cerebral palsy or not.
