If you have hydrocephalus, it is recommended to visit the neurosurgery department at your local hospital and ask a neurosurgeon to assess your current condition. It is generally advised that patients undergo a cranial CT scan or MRI to determine the extent and severity of the hydrocephalus and to choose the appropriate treatment method. For static hydrocephalus, most patients do not exhibit clear clinical symptoms and generally do not require special treatment, regular monitoring is sufficient. For progressive hydrocephalus, surgical treatment is often necessary, and it is generally recommended that patients undergo ventriculoperitoneal shunt surgery. With surgical treatment, most patients can achieve satisfactory results.

What is hydrocephalus shunt?

Patients with hydrocephalus usually require shunt surgery, among which the most common is the ventriculoperitoneal shunt. The shunt tube used in this surgery typically features a reservoir, often referred to by patients as a "water basket". Patients are frequently required to press this reservoir to promote the excess cerebral spinal fluid to flow through the shunt tube into the abdominal cavity, where it is absorbed by the omentum. If the reservoir is not pressed, the shunt tube may become blocked, potentially requiring the surgery to be performed again.

Causes of hydrocephalus in infants

The occurrence of hydrocephalus in infants involves congenital factors, including poor brain development caused by exposure to medications, radiation, rays, and viral or bacterial infections during the embryonic stage, leading to hydrocephalus. Infant hydrocephalus also includes some acquired factors, such as birth injuries occurring during delivery, and post-birth conditions like inflammation in the brain, tumors, or arachnoid cysts. These conditions can lead to excessive production of cerebrospinal fluid, impaired circulation, or insufficient absorption, resulting in hydrocephalus.

Hydrocephalus Clinical Manifestations

In adults, hydrocephalus can be of the normal pressure type, mainly characterized by unsteady gait, slow responses, urinary and fecal incontinence, among others. There is also high-pressure hydrocephalus, which mainly presents as increased intracranial pressure, with the most common symptoms being headache, vomiting, papilledema, and ataxia. In children and infants, hydrocephalus has its own characteristics. In addition to some of the adult symptoms, there are also anomalies such as an abnormally increased head size, bulging fontanelles, "sunset" eye sign, intellectual and cognitive impairments, decreased vision, visual field defects, decreased hearing, epilepsy seizures, and more.

Is hydrocephalus serious?

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.

How to prevent hydrocephalus?

To prevent hydrocephalus, it is first recommended to cultivate good living habits, such as a diet low in salt and fat, and light in nature. Avoid eating overly greasy, spicy, and irritating foods. Additionally, engage in aerobic exercise daily, keeping it under 30 minutes, which can effectively prevent the occurrence of hydrocephalus. For patients with severe cranial trauma or serious central nervous system infections, toxic encephalopathy, etc., if the patient's condition is stable, a timely follow-up head CT scan should be conducted to dynamically observe changes in the patient’s condition. Furthermore, if some patients do not have clear contraindications for surgery, considering a lumbar puncture might be an option to maintain the fluid flow in the brain and prevent hydrocephalus.
