AI Summary Overview
What is Hydrocephalus?
Hydrocephalus is a condition in which an excess of cerebrospinal fluid (CSF) accumulates in the ventricles, or fluid-filled chambers, of the brain. Cerebrospinal fluid is a clear fluid that surrounds the brain and spinal cord. It has a protective role in the nervous system; it eliminates waste products, and it carries nutrients.
Normally, the fluid flows continuously and is absorbed into the blood. On the contrary, in this condition, there is a disturbance of cerebrospinal fluid production, circulation, or absorption. The fluid builds up and enlarges the ventricles, potentially compressing surrounding brain tissue. It can develop at birth (congenital) or later in life as a result of other causes, including infection, injury, stroke, bleeding, and tumour.
What are the Types of Hydrocephalus?
There are several types of hydrocephalus. The type will depend on how the condition develops and how the flow of cerebrospinal fluid is affected.
-
Congenital Hydrocephalus Congenital hydrocephalus is present from birth. It can be caused by abnormal genes or brain and spinal cord development issues in the womb.
-
Acquired Hydrocephalus Hydrocephalus that develops after birth is known as acquired hydrocephalus. It can result from head injuries, brain infections, stroke, brain tumours, or bleeding within the brain.
-
Communicating Hydrocephalus When communicating, CSF can flow between the ventricles. The body, however, does not absorb the fluid sufficiently, and fluid builds up.
-
Non-Communicating Hydrocephalus This occurs when a blockage in the CSF pathway of the brain (also known as obstructive hydrocephalus) interferes with the normal flow of CSF.
-
Normal Pressure Hydrocephalus (NPH) The CSF pressure is typically normal in normal pressure hydrocephalus, and the disease is seen in older adults with enlarged ventricles.
What are the Symptoms of Hydrocephalus?
The symptoms of hydrocephalus depend on the severity of the condition, the cause, and the child's age. Symptoms can come on gradually or suddenly.
-
Symptoms of Hydrocephalus in Infants
- Abnormally fast growth of the head: Head circumference grows faster than expected.
- Swollen fontanelle (soft spot at the top of the head): The fontanelle (soft spot at the top of the head) may be swollen
- Feeding problems: Infants may reject feeds or have trouble feeding.
- Vomiting: When the pressure within the skull increases, vomiting may happen frequently.
- Too drowsy: Babies may appear overly sleepy or hard to arouse.
- Downward eye movement: eyes are fixed downward - sometimes called the "sunsetting" sign.
-
Symptoms of Hydrocephalus in Children and Adults
- Change in visual function: blurred or double vision.
- Headaches can be accompanied by nausea and vomiting.
- Coordination and walking problems: Difficulty with balance and walking.
- Trouble with memory: For some, it is challenging to focus or remember information.
- Changes in behaviour: May become irritated, moody, or change personality.
- Seizures: A few people may experience neurological involvement and therefore seizures.
-
Symptoms of Normal Pressure Hydrocephalus
Normal pressure hydrocephalus may be accompanied by three common symptoms listed below.
- Gait problems: A shuffling gait is typically one of the first symptoms.
- Memory difficulties: May appear very similar to what is observed with dementia.
- Loss of bladder control: Urgency or incontinence can occur.
These symptoms can also occur in other neurological diseases, so thorough evaluation is important.
What Causes Hydrocephalus?
Hydrocephalus happens when the production, flow, or absorption of the cerebrospinal fluid (CSF) is disrupted.
-
Congenital Brain Abnormalities: Some birth defects may affect the flow of CSF and lead to the development of hydrocephalus.
-
Genetic Conditions: Congenital hydrocephalus may be caused by inherited disorders that affect brain development.
-
Brain Haemorrhage: A bleed in the brain can obstruct pathways that drain CSF. This is especially seen in premature babies.
-
Brain Tumours: Tumours may block the normal drainage of CSF, leading to increased CSF in the ventricles.
-
Brain Infections: Infections such as meningitis may result in damage to the tissue that absorbs cerebrospinal fluid.
-
Head Injuries: Traumatic brain injuries could cause disruption to fluid flow and lead to acquired hydrocephalus.
-
Stroke: Damage from a stroke may affect the brain's ability to control the flow and absorption of cerebrospinal fluid.
-
Complications Following Neurosurgery: Sometimes, the hydrocephalus occurs after brain surgery because of changes in the flow of fluid or complications of the surgery.
What are the Complications of Hydrocephalus?
Complications of hydrocephalus depend upon the age at which the condition occurs, its severity, and the speed at which treatment is received. If left untreated, hydrocephalus can impact a variety of physical and mental functions.
-
Speech, learning, and motor skill delays: Infants and children may experience delays in speech, learning, and motor skills.
-
Memory loss, difficulty concentrating: Memory, concentration, and decision-making may be impaired.
-
Vision problems: high pressure inside the brain may cause vision and eye movement to be affected.
-
Seizures: Some people may experience a recurrence.
-
Balance and mobility problems: It may be harder to walk and to move around.
-
Behavioural changes: mood disturbances and personality changes may occur.
-
Incontinence or urinary urgency can affect everyday functioning.
-
Decreased quality of life: Ongoing neurological symptoms can impact functioning at work, school, and social activities.
Many of these complications can be minimised if diagnosed and treated early.
When Should I See My Healthcare Provider?
If you or your child becomes symptomatic and you think you may have hydrocephalus, you should seek medical attention.
See a healthcare provider if you observe:
-
Infant's head growth is greater than normal.
-
Recurring headaches that gradually get worse.
-
Vomiting that does not have a known cause and happens more than once.
-
Difficulty seeing clearly or "double vision" that interferes with activities.
-
New walking/balance problems.
-
Significant memory loss or confusion.
-
Failure to control the bladder, for no other reason.
-
Seizures, extreme drowsiness, or loss of consciousness may need urgent medical attention.
It is crucial to seek prompt medical assessment because, left untreated, hydrocephalus can cause progressive neurological damage.
How is Hydrocephalus Diagnosed?
Hydrocephalus is a diagnosis based on symptoms, neurological examination, and imaging tests to evaluate the brain.
-
Neurological Examination The healthcare provider assesses memory, coordination, balance, vision, reflexes, and muscle strength to determine whether neurological dysfunction is present.
-
Ultrasound Ultrasound in infants is commonly used because it may be able to visualise the brain structures through the soft spot on the infant's head.
-
Magnetic Resonance Imaging (MRI) MRI is able to give detailed images of the brain and is one of the most frequently performed tests to diagnose hydrocephalus.
-
Computed Tomography (CT) Scan Possible enlarged ventricles, bleeding, tumours, or other structural changes affecting the flow of cerebrospinal fluid are identified by CT scans.
-
Lumbar Puncture Sometimes, a small amount of CSF is taken to help diagnose symptoms, as in cases of suspected normal-pressure hydrocephalus.
Diagnostic Overview
| Test Name | What It Evaluates | Findings That May Suggest Hydrocephalus |
| Neurological Examination | Brain and nervous system function. | Abnormalities of memory and balance, vision and/or reflexes |
| Ultrasound | Infants' brain structure. | Enlarged ventricles |
| MRI Scan | Detailed brain imaging | Enlargement of the ventricles and fluid in the ventricles |
| CT Scan | Brain abnormalities and structure. | If a child has enlarged ventricles or a blockage. |
| Lumbar Puncture | Cerebrospinal fluid response | Improving the symptoms temporarily in NPH. |
How is Hydrocephalus Managed or Treated?
Treatment involves restoring normal CSF flow and decreasing CSF pressure:
-
Shunt Surgery The most usual treatment for hydrocephalus is a shunt. The machine allows excess CSF to drain from the brain to another part of the body, typically the abdomen, where it can be absorbed.
-
Endoscopic Third Ventriculostomy (ETV) The minimally invasive procedure establishes a new route for CSF flow, bypassing the blockage and allowing for more normal CSF flow.
-
Monitoring and Follow-Up Care Unfortunately, many individuals with hydrocephalus will need lifelong monitoring. Follow-up appointments are regularly scheduled to monitor symptom progression and to detect complications in treatment.
-
Rehabilitation Therapy
Supportive treatments that may help are:
- Physical Therapy: Enhances balance, mobility, and strength.
- Occupational therapy: Assists in performing daily activities and promotes independence.
- Speech therapy: When required, aids in communication and cognition.
-
Treating Underlying Conditions Treatment of the underlying cause is an important aspect of managing hydrocephalus when it is caused by a tumour, infection, or bleeding.
Does Health Insurance Cover Hydrocephalus?
Yes, most comprehensive health insurance plans in India usually cover treatment for hydrocephalus if it is medically necessary. Generally, the coverage will include hospitalisation expenses, diagnostic tests such as MRI and CT scans, surgical treatment, intensive care, and follow-up treatment.
Coverage varies by insurance company, policy language, and the terms of exclusions and waiting periods. When hydrocephalus is identified as a pre-existing condition at the time of policy issuance, many insurers impose a waiting period, typically 2 to 3 years, before claims related to hydrocephalus become eligible.
Policy documents should be read thoroughly to help ensure you understand coverage restrictions, exclusions, and claim conditions.
How Much Health Insurance Coverage is Needed for Hydrocephalus Treatment?
This will vary depending on the extent of hydrocephalus, the treatment being sought, and the city where care is delivered. In India, hydrocephalus treatment costs can range from ₹1.9 lakh to ₹4.7 lakh per procedure, while non-surgical management may cost between ₹2 lakh and ₹4 lakh per year.
However, some people may need increased coverage, especially in the event of complications, repeated interventions, intensive care needs, extended hospital stays, or rehabilitation. It can help you select a plan that meets your health care requirements by comparing plans.
FAQs
-
Q1. Can hydrocephalus be cured completely?
