Hydrocephalus is a complex disease caused by excessive cerebrospinal fluid production, impaired circulation, and impaired absorption. The symptoms of hydrocephalus are obvious and vary from one age group to another. In infants and young children, hydrocephalus is usually characterized by abnormal cranial enlargement, bulging fontanelle, high tension, angry scalp veins, separation of bones, drowsiness, irritability, headache, nausea, vomiting, visual impairment, and “sunset signs” of the eyes. For older children and adults, acute hydrocephalus is usually characterized by headache, nausea, vomiting, and visual disturbance. Chronic hydrocephalus is mainly characterized by chronic intracranial pressure increase, and may present with bilateral temporal or whole cranial pain, nausea, vomiting, optic nerve papillary edema or optic nerve atrophy, intellectual developmental impairment, motor dysfunction, etc. Elderly people, as a high prevalence of normal pressure hydrocephalus, mainly present with triadic signs, gait disorder, dementia disorder, and urinary incontinence. It is worth mentioning that many dementias due to normal pressure hydrocephalus are often misdiagnosed as Alzheimer’s disease, thus delaying early treatment. After the above introduction, we can see that hydrocephalus has a great impact on the normal development of human body, intellectual development and mental aspects, and timely treatment after diagnosis can help early recovery. To what extent can hydrocephalus recover after treatment? This question needs to be decided in the light of the actual situation of the patient, the condition is mild and timely treatment and recovery is basically the same as normal people, some critical patients through the cerebrospinal fluid specialist technology, scientific standardized treatment, most of them can gradually restore health.
