হাইড্রোসেফালাস

কারণসমূহ

Hydrocephalus occurs when:

• An excess of CSF is produced (rare)
• A blockage that doesn’t allow CSF to drain properly (more commonly)

These problems with the CSF may be caused by:

• ব্রেন টিউমার
• Cancer in the cerebrospinal fluid (CSF)
• Swelling in the CSF (such as sarcoidosis)
• Cysts in the brain
• Malformations of the brain, such as:
  • Dandy-Walker syndrome
  • Arnold-Chiari malformation
  • স্পিনা বিফিডা
• Brain injuries
• Infections of the brain or the meninges can be caused by a number of agents including bacteria, mycobacteria, fungus, viruses, and parasites, such as:
  • Encephalitis—inflammation of the brain
  • Meningitis—inflammation of the membranes that cover the brain and spinal cord
• Problems with the blood vessel in the brain
• Bleeding into the brain or CSF space

ঝুঁকির কারণ

Risk factors for hydrocephalus include:

• Neural tube defects—problems with the development of the brain as a fetus
• Mother has infection during pregnancy, such as:
  • সাইটোমেগালভাইরাস
  • টক্সোপ্লাজমোসিস
  • Lymphocytic choriomeningitis virus
  • জল বসন্ত
  • মাম্পস
• মস্তিষ্কের সংক্রমণ
• Malformations of the brain
• Brain injuries
• Brain hemorrhage

লক্ষণ

Symptoms depend on the severity of the hydrocephalus. The extra CSF puts pressure on the brain. Symptoms may start out mild and become more severe as CSF pressure increases.

উপসর্গ অন্তর্ভুক্ত হতে পারে:

• Headache (often worse when lying down or upon first awakening in the morning or with straining)
• Nausea / Vomiting
• Problems with balance
• হাঁটতে অসুবিধা
• দুর্বল সমন্বয়
• অসংযম
• ব্যক্তিত্বের পরিবর্তন হয়
• বিভ্রান্তি
• Memory problems
• Dementia in the elderly
• Coma and death

In babies, symptoms may include:

• Slow development
• Loss of developmental milestones—no longer able to do activities they once could do
• Bulging fontanelle (soft spot on the head)
• Large head circumference

রোগ নির্ণয়

ডাক্তার আপনার লক্ষণ এবং চিকিৎসা ইতিহাস সম্পর্কে জিজ্ঞাসা করবে। একটি শারীরিক পরীক্ষা সম্পন্ন করা হবে।

Tests to examine the brain may include:

• Computed tomography (CT) scan—a type of x-ray that uses a computer to make pictures of the inside of the brain
• Magnetic resonance imaging (MRI) scan—a test that uses magnetic waves to make pictures of the inside of the brain
• Ultrasound—a test that uses sound waves to examine the brain

চিকিৎসা

চিকিত্সা অন্তর্ভুক্ত হতে পারে:

• Shunt placement (ventriculoperitoneal shunt)—a shunt (a tube placed into the brain) allows excess CSF to drain into another area, usually the abdomen. Sometimes a temporary extraventricular drain (EVD) is placed.
• Third ventriculostomy—a hole is created in an area of the brain. It allows the CSF to flow out of the area where it is building up.
• Removal of the obstruction of CSF flow. For example: removal of tumor or cyst
• Lumbar puncture (spinal tap)—This involves the insertion of a needle between the back bones in the back to remove excess CSF.
• Medicines—In some cases, medicines, such as acetazolamide (Diamox) and furosemide (Lasix), may decrease the production of CSF.
• Other medicines such as steroids or mannitol may decrease swelling around lesions that are causing obstruction of CSF flow.

People who have risk factors for hydrocephalus should be carefully monitored. Immediate treatment might prevent long-term complications.

If you are diagnosed with hydrocephalus, follow your doctor’s instructions.

প্রতিরোধ

There are no known ways to prevent all cases of hydrocephalus. In general:

• নিয়মিত প্রসবপূর্ব যত্ন নিন।
• Keep your child’s vaccines up to date.
• Protect yourself or your child from head injuries.

Certain infections in the mother during pregnancy can cause hydrocephalus in the baby. Examples of infections known to cause problems during pregnancy include:

• Toxoplasmosis—foodborne illness that may be prevented by:
  • Carefully cook meat and vegetables.
  • Correctly clean contaminated knives and cutting surfaces.
  • Avoid handling cat litter, or wear gloves when cleaning the litter box.
• Cytomegalovirus (CMV)—talk to your doctor about identifying CMV in pregnancy
• Lymphocytic choriomeningitis virus (LCV) from pet rodents (mice, rats, hamsters)—avoid rodent contact during pregnancy
• Viruses that cause chickenpox or mumps—can be prevented with vaccinations
