Hydrocephalus is one of the more prevalent diseases in neurosurgery today, and many people may not understand what hydrocephalus is. In fact, before understanding hydrocephalus, we should first recognize what is called cerebrospinal fluid. Cerebrospinal fluid (CSF) is a colorless, transparent fluid that circulates in the brain and spinal cord, and plays a role in cushioning, protecting, and supplying nutrients to the central nervous system of the brain. Under normal circumstances, the amount of cerebrospinal fluid is constant, neither less nor more. However, when certain cranio-cerebral disease factors exist, it is easy to lead to cerebrospinal fluid absorption and circulation obstacles, followed by excessive accumulation of cerebrospinal fluid, which will lead to the gradual enlargement of the ventricular system and the subarachnoid space, thus causing a series of neurological symptoms and the formation of hydrocephalus. Early symptoms of hydrocephalus include headache and dizziness, nausea and vomiting, and blurred vision. Early detection and early treatment will lead to better recovery. Early detection and early treatment will lead to better recovery. If patients delay medical treatment due to negligence, it will lead to more adverse effects, such as increased blood pressure, slow pulse, respiratory disorders, etc., and some patients will experience gastrointestinal bleeding, which poses a direct threat to life and health. Therefore, hydrocephalus should not be taken lightly when it is found, and it is crucial to take active measures for treatment. Can severe hydrocephalus be cured? Although the treatment of hydrocephalus is tricky, medical science is progressing, and under the continuous efforts and research of medical scientists, there are some breakthroughs in the treatment of hydrocephalus.
