If the symptoms of hydrocephalus are detected early, the child should go to the hospital for examination and active treatment after diagnosis. 3 years old is the fastest period of brain development and the golden period for treatment of hydrocephalus in children, so timely and effective treatment has the possibility of recovery. Late treatment has a poor prognosis and may affect the child’s brain development and intelligence. Early clinical manifestations of hydrocephalus include increased head circumference or rapid growth, bulging fontanelle, separate skull sutures, and dilated scalp vessels. In addition, due to the increased pressure in the anterior cranial fossa, the eyes turn down and protrude outward, exposing the upper white sclera and giving the child a “sunset sign” in both eyes. Other symptoms may include depression, drowsiness, restlessness, vomiting, frequent convulsions, paralysis, and difficulty walking.
