Hydrocephalus - Symptoms, Risk factors and Treatment

Hydrocephalus in Urdu

ہائیڈروسیفالس ایک ایسی حالت ہے جس میں دماغ کے وینٹریکلز کے اندر سیریبروسپائنل فلوئڈ (CSF) کا زیادہ جمع ہوتا ہے۔

وینٹریکلز دماغ کے اندر واقع چھوٹے چیمبر ہیں اور CSF پر مشتمل ہیں اور CSF کی پیداوار، نقل و حمل اور ہٹانے میں مدد کرتے ہیں۔ CSF اس کے لیے ذمہ دار ہے:

دماغ کو غذائیت فراہم کرنا

دماغ سے فضلہ کی مصنوعات کو ہٹانا

دماغ کو چوٹوں سے بچانا

جبکہ CSF دماغ کے کام اور تحفظ کے لیے ضروری ہے، لیکن اسے مطلوبہ مقدار میں رہنا چاہیے۔ بہت زیادہ CSF کا نتیجہ ہائیڈروسیفالس میں ہوتا ہے اور دماغ کے لیے نقصان دہ ہے۔ CSF کی معمول کی مقدار کو برقرار رکھنے کے لیے، جسم اسے پیدا کرتا ہے اور اسے دوبارہ خون میں جذب کرتا ہے۔

Hydrocephalus in English

Hydrocephalus is a condition in which there is an excess accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain.

The ventricles are small chambers located inside the brain and contain the CSF and help in the production, transport, and removal of CSF. The CSF is responsible for:

  • Providing nourishment to the brain
  • Removing waste products from the brain
  • Protecting the brain from injuries

While CSF is vital for the function and protection of the brain, it must remain in the required quantity. Too much CSF results in hydrocephalus and is harmful to the brain. To maintain a normal amount of CSF, the body produces it and absorbs it back into the bloodstream. 

Causes of hydrocephalus?

Hydrocephalus is caused by excess accumulation of CSF. Any alteration in the normal circulation of the CSF can result in hydrocephalus, such as:

Obstruction in CSF circulation: The CSF flows through different ventricles and around the brain. Any obstruction in the normal flow of CSF causes its accumulation.

Poor absorption of CSF: As mentioned earlier, to maintain a normal amount of CSF, it is absorbed back into the bloodstream. In some conditions such as trauma to the brain or inflammation of the vessels, the resorption of CSF may be compromised, resulting in its accumulation.

Excess production of CSF: Sometimes, the CSF may be excessively produced, in quantities more than it can be reabsorbed that can cause accumulation of the CSF. 

Types of Hydrocephalus:

Based on the age of onset, presence of obstruction, and change in cerebrospinal fluid pressure, hydrocephalus can be divided into different types:

Congenital hydrocephalus: This refers to hydrocephalus present before birth and occurs when the baby is developing in the fetal period. Aqueductal stenosis is the most common cause of congenital hydrocephalus, a condition in which the passage between the third and fourth ventricle is obstructed. 

Acquired hydrocephalus: This type of hydrocephalus develops later in life due to different causes such as trauma to the brain, infections, brain tumors or brain hemorrhage, etc.

Communicating hydrocephalus (Nonobstructive hydrocephalus): This type of hydrocephalus occurs in the absence of any obstruction of normal CSF flow and is due to impaired resorption of CSF to the bloodstream.

Noncommunicating hydrocephalus (obstructive hydrocephalus): This type of hydrocephalus occurs when the normal flow of CSF is obstructed in between the ventricles. 

Normal Pressure Hydrocephalus: In this type of hydrocephalus, the cerebrospinal fluid pressure remains normal or slightly elevated, but the ventricles dilate to accommodate the excess accumulation of CSF, putting pressure on the accompanying brain tissue. It is a type of communicating hydrocephalus and is more common in the elderly.

Hydrocephalus ex vacuo: In this condition, the CSF accumulation is due to enlargement of ventricles subsequent to the loss of brain tissue in conditions, such as stroke or degenerative diseases such as Alzheimer's. The CSF pressure mostly remains normal in this type.

Symptoms of hydrocephalus:

The signs and symptoms of hydrocephalus vary with age.

Symptoms in infants:

The symptoms of hydrocephalus in infants include:

  • Bulging fontanelle ( soft spot on the head)
  • Unusual increase in the size of the head
  • Downward fixation of the eye
  • Seizures
  • Irritability
  • Poor feeding
  • Vomiting
  • Excessive sleepiness
  • Decreased muscle tone

Symptoms in toddlers and older children:

  • Downward fixation of eyes
  • Crying loudly
  • Increase in the size of the head
  • Double vision
  • Blurred vision
  • Headaches
  • muscle spasms
  • Impaired growth
  • Trouble eating
  • Nausea
  • Vomiting
  • Seizures
  • extreme sleepiness
  • irritability
  • Urinary incontinence
  • The problem in focusing and memorizing
  • Personality changes
  • Impaired coordination and problems in doing simple tasks such as walking

Symptoms in young and middle-aged adults:

The symptoms of hydrocephalus in young and middle-aged adults include:

  • Longstanding headaches
  • Nausea
  • Vomiting
  • Impaired coordination
  • Urinary incontinence
  • Double vision
  • Blurred vision
  • Impaired concentration and memory

Diagnosis of hydrocephalus:

Hydrocephalus is diagnosed by a history and physical exam. Hydrocephalus can be suspected by looking at the baby’s head. To confirm the diagnosis, the doctor may suggest imagining tests such as ultrasound, CT scan, or MRI.

Treatment of hydrocephalus:

To treat hydrocephalus, surgical intervention is needed. Your doctor may suggest the following options:

Ventriculoperitoneal shunting:

In this procedure, a long tube (shunt) is inserted in the brain’s ventricle and on the other end, in the abdomen. This helps in the flow of excess accumulated CSF to the abdomen where it can easily drain. 

Endoscopic third ventriculostomy:

In this procedure, the surgeon makes a small hole at the bottom of the ventricle with the help of an endoscope- a tube attached with a camera to view inside structures. It helps in removing the excess CSF.


Hydrocephalus is a serious condition that requires urgent medical attention. If left untreated, it can result in permanent brain damage. It is important to closely notice any symptoms of hydrocephalus and get it treated on time to prevent complications.
