Hydrocephalus is a disease in which too much cerebrospinal fluid is produced or absorbed, resulting in too much cerebrospinal fluid in the skull. The clinical symptoms and survival time caused by this disease also need to be analyzed according to the specific condition. First of all, in acute hydrocephalus, which is a state of intracranial hypertension within a short period of time, if the patient is not actively treated, it can cause persistent headache, nausea and vomiting, and even impaired consciousness, which can lead to respiratory and circulatory failure at a later stage, resulting in death. Therefore, for acute hydrocephalus, timely treatment is necessary, and the earlier the treatment, the better the prognosis. Secondly, for some chronic hydrocephalus, there are three main clinical symptoms caused by chronic hydrocephalus, the first is urinary incontinence, the second is cognitive decline, and the third is abnormal walking function. If the patient is not actively treated, the hydrocephalus will gradually compress the corresponding nerves as time goes by, causing the above symptoms to become more and more severe, and even to become unconscious. In the later stages, death may occur due to brain herniation. At present, hydrocephalus is relatively well studied and the treatment effect is obvious, so early treatment is recommended.
