Hydrocephalus: Understanding This Rare but Dangerous Brain Condition
**Hydrocephalus**, a rare but dangerous brain condition, causes increased intracranial pressure due to fluid accumulation in the brain. If this condition is left untreated and treatment is delayed, it can lead to severe neurological damage or even be fatal. The following is an in-depth introduction to hydrocephalus. ## **Causes** Hydrocephalus mainly forms for the following reasons: 1. Obstructed cerebrospinal fluid circulation: cerebrospinal fluid circulation in the brain is obstructed, such as by narrowing or blockage of the cerebrospinal fluid pathways, causing fluid to accumulate. 2. Excess cerebrospinal fluid production: when cerebrospinal fluid is produced in excess and cannot be properly processed by the brain, it leads to fluid accumulation. 3. Insufficient cerebrospinal fluid absorption: cerebrospinal fluid cannot be properly absorbed, which may be due to brain disease or impaired absorption function of the meninges. 4. Brain trauma or disease: head trauma, meningitis, brain tumors, and other diseases may also trigger hydrocephalus.
