Brain Infection Facts
The brain and its surrounding structures can become infected by a large spectrum of germs. Bacteria and viruses are the most common offenders. Parasites, fungi, and other organisms can infect the central nervous system.
A brain abscess is usually caused by infection with bacteria or fungi. If the immune system is unable to kill an infection, it will try to limit its spread by using healthy tissue to form an abscess, stopping the pus from infecting other tissue.
Infections of the brain are rare because the body has evolved a number of defenses to protect this vital organ. One of these is the blood-brain barrier, a thick membrane that filters out impurities from the blood before allowing it into your brain.
However, in some cases, germs can get through these defenses and infect the brain. However, the exact location of the original infection can't always be identified.

Get A Second OpinionInfection In The Skull
In most cases, the brain abscess occurs as a complication of a nearby infection in the skull, such as:
- A persistent middle ear infection
- Sinusitis
- Infection of the bone behind the eye
This used to be a major cause of brain abscesses, but because of improved treatments for infections, brain abscesses are now a rare complication of these kinds of infections.
Infection Through The Bloodstream
Infections spread through the blood are thought to account for around one in four cases of brain abscesses. People with a weakened immune system have a higher risk of developing a brain abscess from a blood-borne infection because their immune system may not be capable of fighting off the initial infection.
- Have a medical condition that weakens your immune system - such as HIV or AIDS
- Receive medical treatment known to weaken the immune system - such as chemotherapy
- Have an organ transplant and take drugs to prevent your body from rejecting the new organ
The most commonly reported infections and health conditions that may cause a brain abscess are:
- A type of congenital heart where the heart is unable to carry enough oxygen around the body; this lack of a regular oxygen supply makes the body more vulnerable to infection
- A rare condition in which abnormal connections develop between blood vessels inside the lungs; this can allow bacteria to get into the blood and, eventually, the brain
- A dental abscess or treatment for tooth decay
- Lung infections, such as pneumonia or bronchiectasis
- Infections of the heart, such as endocarditis
- Skin infections
- Infections of the abdomen, such as peritonitis
- Pelvic infections, such as infection of the bladder lining

Direct trauma to the skull can also lead to a brain abscess and is thought to be responsible for 1 in 10 cases.
The most commonly reported causes include:
- A skull fracture is caused by a penetrating injury to the head
- A gunshot or shrapnel wound
Brain Infections Common Treatments
- Antibiotics: Used for bacterial infections.
- Antiviral medications: Prescribed for viral infections.
- Antifungal medications: For fungal infections.
- Corticosteroids: Reduce inflammation and swelling.
- Supportive care: Includes fluids, pain relief, and rest.
- Hospitalization: Severe cases may need intensive care.
Early diagnosis and treatment are crucial for the best outcomes.
Frequently Asked Questions
An infected person may experience symptoms like confusion and delirium resembling encephalitis. More severe cases can lead to coma, seizures, paralysis, and other neurological signs. Most people recover within a few days to weeks with no long-term issues.
Common diseases caused by acute viral infections include encephalitis, flaccid paralysis, aseptic and postinfectious meningitis, and encephalomyelitis.
Brain swelling can persist from a few days to two to three months. Afterward, most individuals fully recover from their symptoms within two to three months.
The survival rate for a brain infection varies widely depending on the type and severity of the infection. Early diagnosis and prompt treatment significantly improve outcomes.
Yes, severe infections affecting the brain can lead to brain death if left untreated or if the infection causes irreversible damage to critical brain functions.
Yes, a CT scan can often detect signs of a brain infection by revealing abnormalities such as swelling, inflammation, or the presence of abscesses in the brain tissue.
Brain infections are relatively rare compared to other health conditions but can occur due to various factors such as viral, bacterial, fungal, or parasitic infections.
