Brain abscess

Brain abscess's disease overview

brain abscess due to many different reasons but all creating pus in the brain parenchyma, the patient is at high risk of death or leaving very serious sequelae later. However, if the patient is detected early and diagnosed and treated promptly, it will help reduce the mortality rate as well as the level of sequelae.

abscess in the brain of healthy objects is often caused by bacterial infection. Brain abscess tends to occur in people with weak immune systems. When the brain abscess, the infection will cause the brain of the edema, creating pus.

In cases of fungal, virus or bacterial abscess entering the brain through the head or infection in another place in the body. Heart and lung infections are one of the most common causes of brain abscess. However, brain abscess may also start from ear infections or sinuses, or even teeth.

Causes of Brain abscess's disease

Causes of brain abscess due to bacteria or fungi or parasites can also cause abscess. When bacteria, fungi or parasites are partially infected with the brain, inflammation and swelling will occur, creating abscesses in the brain including ingredients such as infected brain cells, leuko cells are still alive And died, inflamed creatures. When the abscess is formed, it is surrounded by a membrane that helps isolate infection and keep it from spreading to healthy tissues. However, if the abscess is enlarged, it will pressure the surrounding brain areas. Because the skull does not expand, the pressure from abscess can block blood vessels, prevent oxygen and blood to provide energy to the brain and this leads to damage or destruction of other brain tissue. >

Symptoms of Brain abscess's disease

Symptoms of brain abscess often grow slowly for a few weeks, but also appear suddenly like:

  • Changes in mental health such as increasing confusion, reducing reflexes and feeling uncomfortable
  • Say less
  • Reduce sensation
  • Reduce movement due to loss of muscle function
  • Change the ability to look
  • Change personality or behavior
    • vomit

    Fever

  • chills
    • stiff neck, especially when fever and chills
  • Sensitive to light
  • For babies, there may be additional symptoms such as inflation, vomiting, crying, spasms at limbs.

    • Transmission route of Brain abscess's diseaseBrain abscess

    Brain abscess due to infection is quite rare for many reasons. The body has protective barriers as a network of blood vessels and immune cells will destroy and block some components that are dangerous to the body from blood flow to the brain. Sometimes, infection can overcome this fence of blood.

  • Other parts infected and spread to the brain
  • The infected brain is spread from nearby parts such as ears
  • Due to trauma or surgery
    • Other parts are infected and spread to the brain

    If the infection occurs in another place in the body, infectious organisms can pass through the bloodstream, overcome the goods. Blood-bain barrier (blood-brain barrier) and infection into the brain. Up to 43% of abscess is due to pathogens moving from another part of the body. It is very important, the doctor needs to detect where the pathogenic microorganisms are originated to treat the root, avoiding repeated infections in the future.

    A person with a weak immune system is at risk of brain abscess due to blood infections.

    A person may have a weak immune system if they:

  • HIV -infected people

    • People with AIDS

  • Infants under 6 months of age
  • Patients are being chemotherapy
  • Patients who are using long -term steroid drugs
  • The patient has been transplanted with organs and using immunosuppressive drugs to prevent the elimination of the internal organs.

    • The most common infections are known to cause brain abscess:

  • endocarditis, heart valve infection
  • Pneumonia, bronchitis and other lung infections
  • Abdominal infections such as peritonitis, pelvic area

    • Cystic inflammation The brain is infected by a nearby part such as the ear, if the infection starts inside the skull, such as in the nose or ear, it can spread to the brain, Meet in the following cases:

  • Middle otitis, or middle ear infection
  • Sinusitis
  • osteoarthritis, posterior bone infection

    • The location of the abscess may depend on the position and initial infection. Due to trauma or surgery

    brain abscess may be due to surgery or trauma such as:

  • Neurosurgery or brain injury
  • hit the head causing broken skull, these pieces of brain cells

    • There are strange things in the brain like bullets, if not removed, it will lead to inflammation

    People at risk for Brain abscess's disease

    Nearly anyone can have a brain abscess, but some groups of people are at higher risk than others such as:

  • The immune system is reduced due to HIV or AIDS

    • Cancer and other chronic diseases

    congenital heart disease

  • Head injury or broken skull

    • Meningitis

  • Use immunosuppressive drugs, such as cancer treatments
  • Chronic sinuses or otitis media

    • Some birth defects create conditions for bacteria/fungi/viruses to move to the brain more easily through teeth and intestines as the Fallot quartet ...

    Prevention of Brain abscess's disease

    Some brain abscesses are related to poor oral hygiene or complex sinus infections. Patients should use dentistry daily, brush their teeth properly and often go to the dentist to prevent and treat early and million dental diseases.

    Treatment of sinus infections with nasal pine. If the symptoms of sinuses or tooth infections still persist, patients need medical facilities for medical examination and use.

    Patients with HIV infection if not treated, there is a high risk of brain abscess. Therefore, it is necessary to prevent HIV infection by safe sex. If infected with HIV, patients need to take anti-virus regularly will significantly reduce the possibility of brain abscess.

    Diagnostic measures for Brain abscess's disease

    To diagnose brain abscess, the doctor will evaluate the symptoms and ask for a history of disease such as:

  • Recently infected?
  • Is there diseases that weaken the immune system?

    • Tests may include:

  • Blood tests to check the level of white blood cells to detect infections of the body.
  • MRI or CT scan to see how many abscesses in the brain.

    • Biopsy techniques under the instructions of the CT-Scanner machine for pus sampling for analysis

    Brain abscess's disease treatments

    Current brain abscess treatments include surgery and medicine.

    Today, with advancement in medicine and technology, the chances of recovery after brain abscess are much higher than before. Typically, if the doctor suspects the brain abscess, they will immediately prescribe a broad spectrum antibiotic because the abscess may be life -threatening. If the tests show that infections are caused by a virus, not bacteria, the doctor will change the appropriate treatment. Hiệu quả điều trị sẽ phụ thuộc vào:

  • The size of the abscess
  • How many abscesses
  • Cause of abscess
  • General health status of patients

    • If the abscess is smaller than 1 inch, the patient may only use intravenous antibiotics, antifungal or anti-virus drugs. If the abscess is greater than 1 inch, the doctor will need to suck it, drain or cut it.

    If there are many abscesses, the doctor may appoint surgery.

    In addition to treating abscesses, patients also need to treat other bacterial foci in the body such as in the lungs, abdomen or nose.

    Brain abscess surgery is usually indicated in the following cases:

  • Increasing intracranial pressure
  • The abscess does not respond to drugs

    • There is gas in abscess

  • There is a risk of a broken abscess
