If the imaging shows widening of the lateral ventricle after the baby is born, it may be a symptom of hydrocephalus. Once the diagnosis is clear, the baby can be treated with diuretics, clinical can be intravenous drip 20% mannitol, tachyphylaxis, etc. At the same time, drugs that improve cerebral circulation and promote brain oxygenation, such as cerebral protein hydrolysate, can be used as appropriate, which will help promote the activity of brain cells and facilitate the rapid recovery of the disease. If the baby has limb disorders due to hydrocephalus, it is necessary to exercise more limb functions. The doctor will choose the rehabilitation method according to the restricted parts and degree of the child, for example, the limited function of the legs can walk more, while the limited function of the hands can do more lifting exercises, which also helps to promote the rapid recovery of brain motor functions. Once the condition worsens along with the rapid growth of infants and toddlers, it may lead to mental retardation or other sequelae if not treated in time.
