About Hydrocephalus

Overview
Hydrocephalus, also known as water in the brain, is a neurological disorder characterized by an abnormal buildup of cerebrospinal fluid (CSF) in the ventricles (cavities) deep within the brain. This excess fluid causes the ventricles to widen, putting harmful pressure on the brain's tissues. Hydrocephalus can be present at birth or develop over time due to damage or injury. CSF is a clear fluid that surrounds and protects the brain and spinal cord. It flows through the ventricles and bathes the brain and spinal cord before being reabsorbed into the bloodstream. When there is an excessive buildup of CSF, it can impair brain function and potentially lead to brain damage or even death. Symptoms of hydrocephalus can vary from person to person and depend on age. Hydrocephalus usually manifests in infants and people aged 60 years and older. Prompt treatment is necessary to prevent serious complications.
Causes and Risk Factors

The causes of hydrocephalus involve various genetic and environmental factors. Some key mechanisms include:

  • Dysfunction of certain brain structures
  • Abnormalities in brain cells

Non-modifiable risk factors for hydrocephalus are factors that cannot be changed. These include:

  • Premature birth: Infants born preterm have a higher risk of intraventricular hemorrhage, which can lead to hydrocephalus.
  • Problems during pregnancy: Infections in the uterus during pregnancy can increase the risk of hydrocephalus.
  • Problems with fetal development: Incomplete closure of the spinal column is an example of a developmental issue that can increase the risk.

Modifiable risk factors for non-infant hydrocephalus are factors that can be changed and influenced which are related to individual habits and lifestyle. They are:

  • Poor dietary habits: Maintaining a healthy diet is recommended to reduce the risk of complications associated with hydrocephalus.
  • Low physical activity: Regular physical activity is important for overall health and may help prevent certain conditions that can contribute to hydrocephalus.

It is important to note that these risk factors may vary depending on individual circumstances, so it is always best to consult with a healthcare professional for personalized advice.

Symptoms

The most common early symptoms of hydrocephalus include:

  • Rapid increase in head circumference in infants
  • Bulging fontanelle (soft spot on the surface of the skull) in infants
  • Irritability and fussiness in infants
  • Seizures in infants
  • Vomiting in infants and at any age
  • Lethargy in infants and at any age

As hydrocephalus progresses or becomes more severe, the following symptoms may occur:

  • Difficulty walking
  • Loss of athletic abilities
  • Change in personality
  • Decrease in mental abilities
  • Headaches
  • Muscle spasms
  • Delayed growth
  • Trouble eating
  • Extreme sleepiness
  • Irritability
  • Loss of coordination
  • Loss of bladder control

It is important to note that these symptoms can vary depending on the age of onset and individual circumstances. It is always recommended to seek medical attention for proper diagnosis and treatment. Seek prompt medical attention if the above symptoms persist or recur frequently.

Diagnosis

To diagnose hydrocephalus, the following examinations, tests, and procedures are commonly performed:

  • Clinical neurological exam: This involves assessing muscle strength and reflexes, coordination and balance, vision, eye movement, hearing, mental functioning, and mood.
  • Ultrasound: This is often the first test used in infants as it is simple and low risk. It can detect hydrocephalus in unborn babies during routine prenatal exams.
  • Magnetic resonance imaging (MRI): This test can determine if the ventricles (fluid-filled spaces in the brain) are enlarged, assess cerebrospinal fluid (CSF) flow, and provide information about the brain tissue surrounding the ventricles. It is usually the initial test used to diagnose adults.
  • Computed tomography (CT): This imaging test can show if the ventricles are enlarged or if there is an obstruction.
  • Spinal tap (lumbar puncture): This procedure allows doctors to estimate CSF pressure and analyze the fluid by inserting a needle in the lower back and removing and testing some of the fluid.

To determine the stage or severity of hydrocephalus, additional examinations, tests, and procedures may include:

  • Physical exam: The healthcare provider will perform a complete physical examination with emphasis on a detailed neurological examination.
  • Lab tests: Specific lab tests such as blood draws may be recommended to gather more information.
  • Imaging studies: Additional imaging studies like X-rays or MRI may be performed to further evaluate the condition.
  • Clinical procedures: Depending on your symptoms and body system being evaluated, clinical procedures such as hearing tests may be recommended by your healthcare provider.
  • Genetic tests: In some cases, genetic testing may be performed to identify any genetic changes that could be associated with hydrocephalus.

Remember to consult with your healthcare professional for personalized advice regarding examinations, tests, and procedures for diagnosing and determining the stage or severity of hydrocephalus.

Treatment Options

The goals of treatment for hydrocephalus are:

  • Restore cerebrospinal fluid (CSF) flow: The main objective is to restore the normal CSF in the brain. This can be achieved through surgical interventions such as shunt insertion or ventriculostomy. Shunt insertion involves placing a drainage system (shunt) to help CSF flow at a normal rate and in the right direction. Ventriculostomy, on the other hand, involves creating a hole in the ventricles to allow CSF to leave the brain and relieve pressure.
  • Prevent further brain damage: Surgical interventions like shunt insertion or ventriculostomy help in restoring the flow of CSF, which prevents additional brain damage.
  • Relieve symptoms: Treatment also focuses on relieving symptoms associated with hydrocephalus, such as headaches, nausea, and vision problems. Medications may be prescribed to manage these symptoms.
  • Minimize complications: Treatment aims to minimize complications related to hydrocephalus, such as infection or malfunction of the shunt system. Regular monitoring of shunt implants is necessary to ensure their proper functioning.

It is best to consult with a healthcare professional who can provide personalized advice based on individual circumstances.
