Hydrocephalus: Causes & Risks
Hydrocephalus: Causes & Risks Hydrocephalus is a serious condition where too much cerebrospinal fluid (CSF) builds up in the brain. This fluid buildup puts too much pressure on the skull. It’s important to know what causes this to happen because it can lead to serious health problems.
Many things can lead to hydrocephalus, like genes or other health issues. It’s key to know the risks to help those who might get it and doctors who can treat it early. We will look into what causes hydrocephalus, its types, and why catching it early is so important.
Hydrocephalus: Causes & Risks What is Hydrocephalus?
Hydrocephalus: Causes & Risks Hydrocephalus is a condition where too much cerebrospinal fluid (CSF) builds up in the brain’s ventricles. This extra fluid puts pressure on the skull. It can cause symptoms and harm brain tissues.
Definition of Hydrocephalus
The hydrocephalus definition is about too much cerebrospinal fluid in the brain’s ventricles. This fluid cushions the brain, removes waste, and gives nutrients. But, if it’s made or absorbed wrongly, it leads to hydrocephalus.
Types of Hydrocephalus
Hydrocephalus is split into types by how cerebrospinal fluid flows:
- Communicating Hydrocephalus: This happens when CSF flows well between ventricles but absorbs poorly. So, CSF moves but doesn’t get absorbed right.
- Non-communicating Hydrocephalus: This is also called obstructive hydrocephalus. It’s when a blockage stops CSF from flowing normally between ventricles.
- Congenital Hydrocephalus: This is present at birth and comes from developmental issues.
- Acquired Hydrocephalus: This starts after birth from things like infections, head injuries, or tumors.
Knowing the difference between congenital hydrocephalus and acquired hydrocephalus helps pick the right treatment. Also, knowing if it’s communicating hydrocephalus or non-communicating hydrocephalus helps find the cause and how to treat it.

Hydrocephalus has many causes, both genetic and acquired. Looking into these helps us understand it better.
Genetic Factors
Hydrocephalus: Causes & Risks Some genes make people more likely to get hydrocephalus. Things like spina bifida and certain syndromes can cause it. Knowing about family history helps spot the risks.
Acquired Factors
After birth, many things can cause hydrocephalus. Brain injuries or a brain bleed can block fluid paths. Infections like meningitis can also cause it by making the brain inflamed.
Tumors, good or bad, can stop the fluid from flowing right. These are big reasons for getting hydrocephalus later on.
| Cause of Hydrocephalus | Description | Impact |
|---|---|---|
| Genetic Factors | Includes birth defects like spina bifida and genetic syndromes | Congenital hydrocephalus |
| Brain Hemorrhage | Bleeding within the brain obstructs cerebrospinal fluid pathways | Acquired hydrocephalus |
| Infection-Related Hydrocephalus | Infections like meningitis cause inflammation and block fluid pathways | Acquired hydrocephalus |
| Brain Tumors | Tumors obstruct cerebrospinal fluid flow | Acquired hydrocephalus |
How Do You Get Hydrocephalus?
Hydrocephalus happens when many things come together. It can be either from birth or happen later. Let’s look at why it might happen.
Some people get it because of things that happen before they are born. This is called congenital hydrocephalus. It’s often because the brain doesn’t make cerebrospinal fluid (CSF) flow right. For instance:
- Aqueductal Stenosis: This means the passage between the third and fourth ventricles in the brain is too narrow.
- Dandy-Walker Malformation: This is a brain problem from birth that affects the cerebellum and the spaces filled with fluid.
Acquired hydrocephalus happens later in life. It can be caused by things like:
- Head Trauma: A brain injury can mess up how CSF moves.
- Infections: Things like meningitis can cause inflammation and block CSF flow.
- Tumors: Brain tumors can block CSF from moving.
Knowing why hydrocephalus happens is important. It usually comes from too much or too little CSF. This can happen in different ways, like:
- CSF Overproduction: Sometimes, the choroid plexus makes too much CSF.
- Impaired CSF Absorption: The parts that absorb CSF might not work right.
- Obstructive Hydrocephalus: A blockage in the ventricles stops CSF from flowing.
Getting hydrocephalus can take many paths. It’s important to know these paths to understand and treat it. Whether it’s from genes, injury, or illness, knowing the causes helps with diagnosis and treatment.
Symptoms of Hydrocephalus
Hydrocephalus shows up differently in kids and grown-ups. This is because kids’ skulls are softer and their brains are still growing. Spotting these signs early is key to helping them.
Common Symptoms in Infants
In babies, signs of hydrocephalus include a big head and a soft spot on the head that sticks out. They might also move slower than other babies and get easily upset.
- Enlarged head size: A big head is a clear sign.
- Bulging fontanelle: The soft spot on top of the head gets tense and sticks out.
- Developmental delays: Babies with hydrocephalus might not roll over, sit, or crawl as they should.
Common Symptoms in Adults
Grown-ups with hydrocephalus show different signs. They often have headaches and may feel sick, throw up, and have trouble with balance and moving right.
- Headache: They usually have bad headaches.
- Nausea and vomiting: These come from the pressure in their head.
- Cognitive difficulties: They might forget things or find it hard to focus.
Diagnosing Symptoms Accurately
Spotting hydrocephalus early can prevent serious problems. But, it’s hard to diagnose because it can look like other health issues. Doctors use tests, pictures of the brain, and the patient’s history to make sure they’re right. Catching the signs early, like a big head in babies or ongoing headaches in adults, helps a lot with treatment.
Who is at Risk of Developing Hydrocephalus?
Knowing who might get hydrocephalus helps catch it early. Age and health issues are big factors.
Age-Related Risks
Babies and older people face higher risks of getting hydrocephalus. Babies might get it from birth problems. Older folks could get it from brain shrinkage, stroke, or injury.
Spotting the signs early in these groups can help a lot.
Medical Conditions Increasing Risk
Some health issues make getting hydrocephalus more likely. This includes tumors, infections in the brain, and problems from past surgeries. Keeping an eye on people with these issues is key.
| Age Group | Key Risk Factors |
|---|---|
| Newborns | Birth defects, complications during delivery |
| Elderly | Brain atrophy, stroke, trauma |
| Others with Health Conditions | Tumors, CNS infections, prior surgeries |
Checking on people at high risk for hydrocephalus signs helps manage it better.
Diagnosing Hydrocephalus
Finding out if someone has hydrocephalus is very important. Doctors use special tests and look at brain images to make sure they know what’s going on.
Imaging Techniques
Tests like MRI and CT scans are very important for finding hydrocephalus. An MRI for hydrocephalus shows the brain in detail. This helps doctors see if there’s a problem and what might be causing it. A CT scan head is also used, especially when you need quick results.
| Imaging Technique | Description | Strengths |
|---|---|---|
| MRI | Uses magnetic fields to produce detailed images of brain structures. | Highly detailed, ideal for identifying subtle changes in brain tissue. |
| CT Scan | Uses X-rays to create cross-sectional images of the brain. | Quick and efficient, useful in emergency situations. |
Doctors also use other tests like a lumbar puncture diagnosis. This test checks the pressure and what’s in the cerebrospinal fluid.
Medical History and Physical Exam
Doctors look at your medical history and do a physical check-up to diagnose hydrocephalus. They want to know about your symptoms and any health issues you’ve had before. They check how your muscles work, your reflexes, and how your nerves are doing.
- Review of past medical records
- Symptom evaluation
- Neurological assessments
Using tests, history, and physical checks helps doctors find out if someone has hydrocephalus fast and right. This means they can start the right treatment quickly.
Complications Associated with Hydrocephalus
Hydrocephalus can cause different problems, depending on how severe it is and the treatment. Knowing about these problems helps manage the condition better. This can make life quality better for patients.
Short-Term Complications
Short-term issues with hydrocephalus include high pressure in the brain. This can make people feel very bad. They might have headaches, throw up, or even pass out.
Putting in a shunt to help with the condition can also be risky. Shunt infections can make people have a fever and more white blood cells.
Long-Term Complications
Long-term problems with hydrocephalus can really affect people’s lives. It can make learning hard and memory tricky. Shunts might not work right, causing more symptoms and needing more surgery.
People might also have trouble moving and need to go to the hospital often for their shunts. They need to see doctors regularly to manage their condition.
| Type | Complication | Impact |
|---|---|---|
| Short-Term | Increased intracranial pressure | Headaches, vomiting, loss of consciousness |
| Short-Term | Shunt infection | Fever, increased white blood cell count |
| Long-Term | Cognitive impact of hydrocephalus | Learning disabilities, memory issues |
| Long-Term | Shunt malfunction | Recurring symptoms, surgical revisions |
| Long-Term | Motor impairments | Movement difficulties, frequent hospital visits |
Current Treatment Options for Hydrocephalus
Treating hydrocephalus uses surgery and other methods. The goal is to ease symptoms and fix the CSF buildup. This helps the brain work better.
Surgical Treatments
Surgery is key for managing hydrocephalus. Shunt surgery is common. It puts in a tube, or shunt, to move CSF away from the brain. This stops pressure and protects the brain.
Hydrocephalus: Causes & Risks Endoscopic third ventriculostomy (ETV) is another choice. It’s a small surgery that opens a hole in the brain. This lets CSF flow better and lowers pressure. It’s good for some patients who don’t do well with shunts.
Hydrocephalus: Causes & Risks Non-Surgical Treatments
Hydrocephalus: Causes & Risks Even with surgery, non-invasive treatments are important. Doctors might give medicines to help with CSF or ease symptoms. Checking up with scans is also key to see how the condition changes. This helps doctors adjust the treatment.
Handling hydrocephalus needs a mix of surgery and other treatments. By making a plan that fits each person, doctors can give better care. This way, patients get the best help for their condition.
