Types Of Hydrocephalus And How They Affect the Brain?

Your thoughts, movements, memories, and emotions are all under the control of a single organ, the brain. It needs to maintain a balance between fluids and tissues for proper functioning. Of utmost importance among the fluids is cerebrospinal fluid (CSF). This fluid acts as cushioning for the brain, providing nutrition, removing wastes, and protecting the central nervous system from injury.

The buildup of this fluid within the ventricles of the brain is referred to as hydrocephalus, a condition that may require hydrocephalus treatment depending on its cause and severity. Excess CSF leads to exerting additional pressure on the brain, which in turn may lead to damage to delicate brain tissue.

Moreover, there are several different types of hydrocephalus; therefore, it is important to understand them in order to find the cause of the disease.It also demonstrates the need for a compassionate specialist like Dr Taimoor Ahmed, who is highly regarded for his advanced neurological treatment approaches.

In addition, his patient-focused strategies are his specialty. This blog will spotlight all the types of hydrocephalus to let you identify their possibility of occurrence and approach the right expert in the field.

What is Hydrocephalus?

This condition occurs when there is an impairment in the production, absorption, or movement of CSF. In a healthy body, CSF flows continuously in the ventricles as well as around the brain and the spinal cord before going into the bloodstream.

In case there is an interruption in this flow, CSF builds up in the ventricles, leading to their swelling. With pressure building, the compression transfers to the brain tissues surrounding the ventricles. All things together interfere with the normal functions of the brain. Several factors, including age and the cause of the fluid build-up, determine symptom presentation. The condition may occur gradually or suddenly.

How does hydrocephalus affect the brain?

The brain sits inside the hard skull that provides very limited space for growth. As mentioned above, hydrocephalus is a medical condition that refers to Cerebrospinal fluid accumulation. As this fluid fills the brain, the ventricles expand and compress the adjacent brain tissues.

The resulting pressure might affect brain structures that control motor skills, memory, balance, vision, speech, learning, and cognition. In infants who have not yet developed their skull completely, hydrocephalus can result in the enlargement of the baby’s head. But, in older individuals, it causes headaches, nausea, vision impairments, confusion, and neurological defects due to the inability of the skull to grow further.

In the absence of treatment, the continued pressure might harm brain neurons and impair the process of neurological development.

Knowing about the types of hydrocephalus

On the basis of its cause and how cerebrospinal fluid circulation is affected, there are different types of hydrocephalus. The following description can explain these.

1. Congenital Hydrocephalus

Congenital hydrocephalus is a condition which exists at birth, occurring while the infant is still inside the mother’s womb. This may arise due to genetic issues, malformations, or infections. The commonest cause of congenital hydrocephalus is the stenosis of the cerebral aqueduct, a passage through which the CSF flows from one ventricle to another. The other possible causes of this disorder include spina bifida, neural tube abnormalities, and chromosomal anomalies. Some symptoms of congenital hydrocephalus are:

Rapid head growth
Protruding fontanelle
Problems with eating
Sunset eyes
Growth delays
Seizures

Children with congenital hydrocephalus can have good neurologic results with timely surgery and developmental support.

3. Communicating Hydrocephalus

Meningitis
Subarachnoid hemorrhage
Brain infection
Brain inflammation

Since the problem here is absorption and not the flow of CSF, this condition causes a gradual increase of the fluid within the brain, causing intracranial pressure. Headaches, loss of balance, memory problems, vision disturbances, and changes in cognitive functioning can be some of the symptoms.

2. Acquired Hydrocephalus

Brain injury
Brain tumor
Stroke
Meningitis
Hemorrhages in the brain
Brain surgery complications

The symptoms vary according to age but may include:

Headaches
Vomiting and nausea
Blurred vision
Difficulty walking
Impaired memory
Confusion
Fatigue
Changes in personality
Seizures

Treatment involves draining the excess fluid and treating the underlying problem causing the excess fluid in the brain.

4.Non-communicating (Obstructive) Hydrocephalus

Brain tumors
Congenital stenosis of the cerebral aqueduct
Cysts within the brain
Scar tissue
Congenital
malformation

Due to the inability of the cerebrospinal fluid to flow, pressure starts building up behind the obstruction. Clinical presentation may come on suddenly if the obstruction forms rapidly and includes:

Headache
Vomiting
Diplopia
Lethargy
Difficulty in ambulation
Confusion
In some cases, loss of consciousness

5. Normal Pressure Hydrocephalus

Normal Pressure Hydrocephalus(NPH) mostly occurs in older individuals, usually older than 60 years. However, this is not a pet rule; exceptions regarding age are also possible. In this type of condition, though there is an accumulation of cerebrospinal fluid inside the ventricles, the pressure can be normal. But, ventricular size increases and compresses the adjacent brain tissue slowly. There are three prominent symptoms in NPH:

Difficulties with walking (shuffling gait)
Loss of memory/cognitive dysfunction
Urinary incontinence

Due to similar symptoms to Alzheimer’s disease or Parkinson’s disease, the diagnosis of NPH is often slightly complicated. In contrast to other dementia-related disorders, NPH can respond well to surgery after appropriate diagnosis.

Common Symptoms across different types of hydrocephalus

Even though symptoms differ based on age and condition.

Many people show similar signs

Headaches
Nausea and vomiting
Vision changes
Balance difficulties
Problem in walking straight
Memory impairment
Poor focus
Confusion
Fatigue
Seizures
Changes in personality

In Infants and Children

Increased head size
Protruding fontanelle
Feeding problems
Irritability
Developmental delay

Any long-term neurological symptoms need to be examined by a doctor.

Wrapping Up

In the end, hydrocephalus is a complicated disease that may occur at any age. But if a person recognizes their symptoms early and receives proper treatment, the results could be beyond expectations. Various types of hydrocephalus have different clinical presentations and also require different treatment approaches. Among the most prominent types are communicating, non-communicating, and normal pressure hydrocephalus.

They may cause symptoms such as headaches, vision problems, and much more, depending on their severity and underlying causes. For patients who require surgical treatment, understanding what is a VP shunt can also be helpful, as a ventriculoperitoneal (VP) shunt is one of the treatment options used to manage certain cases of hydrocephalus.

In this context, the role of dedicated health experts like Dr. Taimoor Ahmed, a leading neurologist in Sialkot, is undeniable. He is committed to providing safer, advanced, and highly effective treatments that help improve his patients’ quality of life. Thanks to developments in the methods of diagnostics, neurosurgery, and rehabilitation, many people with hydrocephalus have a chance to lead healthier lives.
