30 Dec Understanding Hydrocephalus Treatment Options and Prognosis
Hydrocephalus is a neurological condition characterized by an abnormal buildup of cerebrospinal fluid (CSF) within the brain’s ventricles, or cavities. This accumulation can increase pressure inside the skull, which may cause brain tissue damage and functional impairments. Here is information on the causes, symptoms, and available treatments for hydrocephalus:
Why Does Hydrocephalus Occur?
Hydrocephalus develops when the delicate balance between CSF production, circulation, and absorption is disrupted. This condition can be present at birth or develop later in life. It may be caused by events like:
- Head Injuries
- Brain Tumors
- Infections (Such as Meningitis)
- Bleeding Within the Brain
A hydrocephalus imbalance can result from an obstruction that blocks the normal flow of fluid, poor absorption by the blood vessels, or, in rare cases, excessive production of CSF.
What Is Cerebrospinal Fluid For?
Cerebrospinal fluid is a clear, colorless liquid that surrounds the brain and spinal cord, and it serves several major functions. It acts as a cushion, protecting the brain from injury within the hard structure of the skull. CSF also circulates nutrients and chemicals filtered from the blood while removing waste products from the brain, and it helps regulate intracranial pressure to maintain a stable environment for brain function.
Can Hydrocephalus Be Cured?
There is currently no cure for hydrocephalus, but it is a manageable condition with medical intervention. Treatment focuses on restoring and maintaining normal CSF levels within the brain. It is one of the more common developmental disabilities, affecting approximately one to two out of every 1,000 babies born in the United States. The condition can also develop at any age, so its overall prevalence includes individuals who acquire it later in life.
What Are the Symptoms?
Symptoms of hydrocephalus vary by person, and the pressure on the brain can manifest differently across age groups. In infants, the most apparent sign is often an unusually large head size or a rapid increase in head circumference. Other symptoms may include a bulging soft spot (fontanel) on the top of the head, vomiting, sleepiness, and a downward deviation of the eyes.
Older children and teenagers may experience symptoms such as:
- Severe Headaches
- Blurred or Double Vision
- Balance and Coordination Problems
- Nausea
- Fatigue
Adults with hydrocephalus may present similarly to older children and teens, but the condition may present differently in seniors. Normal pressure hydrocephalus (NPH) is a specific form that seniors can develop. It commonly causes symptoms like cognitive decline, gait disturbance, and a loss of bladder control.
How Is This Condition Treated?
The primary goal of treatment is to reduce the pressure on the brain by draining the excess cerebrospinal fluid. This is typically achieved through one of two main surgical procedures. The most common treatment is the surgical implantation of a shunt system. A shunt is a flexible tube with a catheter and a valve that creates a channel to divert CSF from a ventricle in the brain to another part of the body where it can be absorbed. The valve regulates the pressure and prevents over-draining or backflow of fluid.
An alternative procedure for some is an endoscopic third ventriculostomy (ETV). In this surgery, a neurosurgeon uses a small camera to see inside the brain and creates a tiny hole in the floor of the third ventricle, which allows the trapped CSF to bypass an obstruction and flow into its normal pathway. This procedure is often recommended for hydrocephalus caused by a specific blockage.
Contact a Neurologist Today
Hydrocephalus is a complex condition that requires specialized medical care, and a neurologist can provide a comprehensive evaluation. If you or a loved one is experiencing any of the symptoms discussed, contact a neurologist for a consultation. They can discuss appropriate diagnostic tests, treatment options, and long-term prognosis.
