Hydrocephalus is a relatively severe neurological disorder, generally caused by disturbances in cerebrospinal fluid (CSF) circulation, leading to obstructive hydrocephalus due to blocked circulation pathways. Other causes include overproduction of CSF or reduced absorption, which can also lead to hydrocephalus. If the volume of hydrocephalus is not large, the clinical symptoms are generally not obvious, and the patient may only experience dizziness, slow response, cognitive impairment, and unstable walking. If the hydrocephalus is significant, it often causes severe compression of brain tissue, which can lead to consciousness disturbances, progressive dementia, epileptic seizures, and incontinence. Timely surgical intervention is necessary to relieve the pressure caused by the edema.
