What Are Brain Infections? Causes, Symptoms and Treatment

A brain infection takes place when an infecting agent enters the brain, brain coverings or tissues located in the immediate proximity. In case of infection of one of these regions, encephalitis (brain inflammation) or meningitis (inflammation of the membranes covering the brain and spinal cord) will be diagnosed.

There are infections that come suddenly with severe symptoms and those that occur gradually. Proper medical care must be sought immediately because some of brain infections affect memory, movement and consciousness and other brain functions.

What Causes Brain Infections?

Brain infections can be caused by many infectious agents. The most common are:

1. Infections Viruse

Viruses are common causes of encephalitis and meningitis. After infecting other parts of the body, some viruses can spread into the nervous system. Herpes viruses, enteroviruses and some mosquito or tick borne viruses are examples.

2. Bacterial Infections

BThe bacteria can cause diseases such as bacterial meningitis or brain abscesses. Such diseases progress quickly and demand quick treatment.

3. Mycotic Infections

There are mycotic infections that attack the brain, although these are relatively rare, occurring mainly in patients with compromised immune systems. These infections may affect the brain tissue or the protective membranes surrounding the brain.

4. Parasitic Infections

The brain is also affected by various parasites. These can lead to inflammation, cyst formation or other neurological problems.

5. Spread From Nearby Infections

Sometimes infection elsewhere in the body can travel to the brain or its coverings. Occasionally infections of the ear, sinuses, lungs, or blood can lead to serious neurological complications.

What Are the Symptoms of a Brain Infection?

The symptoms may vary depending on the cause, location, severity and age of the patient. Here are some common signs to watch for:

• Severe or ongoing headache
• Temperature
• Nausea or vomiting
• Photo sensitivity
• Weird or confusing behavior
• Excessive sleepiness or trouble staying awake
• Neck stiffness
• Fits and seizures
• Trouble speaking or understanding speech
• Weakness or trouble moving an arm or leg
• Problems with balance and coordination
• Problems with memory or concentration
• In severe cases loss of consciousness

Not all of these symptoms will develop in all patients. If you have a combination of fever, severe headache, confusion, seizures, or decreased consciousness, treat this as a medical emergency and get evaluated immediately.

When Should You See a Doctor?

Get emergency help if you or the person you are with experiences a severe headache with fever, confusion, seizures, stiff neck, weakness, speech problems, or unconsciousness.

Early diagnosis will enable physicians to detect the infection and treat it before any complications occur. Occasionally, there are atypical presentations in children and older patients and in individuals with compromised immunity systems, and changes in mental status should never be overlooked.

How Are Brain Infections Diagnosed?

Physicians begin by taking a detailed history and doing a neurological examination. Depending on the symptoms, a number of tests can be recommended.

Brain Imaging

Sometimes a brain CT scan or MRI can show inflammation, swelling, an abscess, or other changes in the brain.

Blood tests.

Blood tests can help identify signs of infection and inflammation and give some clues as to potential cause.

Lumbar (spinal) tap

Sometimes doctors examine cerebrospinal fluid (CSF), the fluid that surrounds the brain and spinal cord. Lumbar puncture can be useful in the diagnosis of infections such as meningitis. It gives useful information about the organism responsible.

Other examinations

Depending on the suspected infection, doctors might recommend tests such as cultures, molecular tests, or an electroencephalogram (EEG) if seizures or changes in brain function are observed.

How Are Brain Infections Treated?

Treatment depends on the type of infection, how severe it is and the general condition of the patient. One treatment doesn’t work for every brain infection.

Antibiotics

Antibiotics might be needed for bacterial infections. Severe bacterial infections often need to be treated in hospital, sometimes with intravenous medication.

Antivirals

Some viral brain infections can be treated with antiviral medicines. The choice of drug will depend on which virus is suspected or confirmed.

Antiparasitic or Antifungal Medicines

If an infection is found, the doctor may prescribe specific medicines for the fungal or parasitic infection.

Treatment of Brain Swelling and Other Symptoms

Some patients may need treatment to control brain swelling, seizures, fever, pain or other complications. Severe cases may need close observation in an intensive care unit.

The correct medication or delayed treatment can cause an infection to worsen, so treatment must always be directed by a qualified neurologist or another appropriate specialist.

Can Brain Infections Be Prevented?

Some infections of the brain can be prevented, but not all. The following may help reduce risk:

• Stay up to date on your routine vaccines.
• Practice good hand hygiene.
• Avoid close contact with persons who have contagious infections as appropriate.
• Protect yourself from bites in areas where mosquitoes and ticks spread infections.
• Prompt treatment of serious infections in other parts of the body.
• Practice safe food and water habits
