Encephalitis Causes, Symptoms & Treatment

By BulkSupplements More Blogs by This Author

What is Encephalitis?

rn

Encephalitis is a condition in which the human brain becomes inflamed. Around 250,000 patients were diagnosed and hospitalized in the United States in the last decade as a result of this disease. Additionally, doctors report approximately 6,000 cases of encephalitis in the United Kingdom each year.

rn

The condition may be infectious or autoimmune. In infectious encephalitis, the brain swells as a result of an infection. But in autoimmune encephalitis, the brain swells because of an autoimmune disease or after an infection that causes an autoimmune response. Symptoms range from mild to severe and include symptoms similar to thefluand changes in behavior, speech and consciousness. Without treatment, encephalitis causes severe complications and may be fatal.

rn

Encephalitis vs. Meningitis

rn

Meningitisis a similar condition to encephalitis. They both cause immune-related inflammatory responses in the brain, but they affect different parts of it. Meningitis is an inflammation in the three membranes that cover the brain and spinal cord called the meninges. But encephalitis causes inflammation in the brain itself. Their causes both may include bacteria, viruses and fungi and the inflammation may cause similar health complications.

rn

Encephalitis Causes

rn

In a large amount of cases, doctors cannot identify a cause for encephalitis. But in most identifiable cases, it is a result of a virus. The most common causes are herpes simplex virus types 1 and 2, arboviruses and enteroviruses. Herpes simplex encephalitis progresses very quickly and according to research, this virus is responsible for 10 percent of encephalitis cases.

rn

Enteroviruses are very contagious and they spread through contaminated food, water or airborne objects. Arboviruses spread to humans through bites from mosquitoes that carry the infection. In fact, there are four forms common in the U.Seastern and western equine encephalitis, La Crosse encephalitis, St. Louis encephalitis and West Nile encephalitis. However, outside the United States, Japanese encephalitis is very common worldwide. Thehuman immunodeficiency virus (HIV)may also cause encephalitis. In addition, tick-borne encephalitis and the rare Powassan virus infection spread through tick bites.

rn

Any virus can potentially lead to encephalitis, but not all patients with an infection will develop it. Most of the time the cause of infectious encephalitis is a virus, but it may develop from a fungus, bacteria or parasite.

rn

Primary vs. Secondary Causes

rn

There are two different ways that encephalitis can occur. The virus may either attack the brain and the spinal cord directly (primary encephalitis) or it may also develop from a past infection if the virus reactivates in the body. An infection in another part of the body may also spread to the brain and cause inflammation (secondary encephalitis).

rn

Lastly, the virus may activate an autoimmune response that causes the bodys own immune system to mistakenly attack the brain and cause inflammation. In some cases, autoimmune encephalitis develops as a result from an infection as well and in other cases, the patient has antibodies in the blood that may be connected to the autoimmune response that attacks healthy tissue. However, medical experts have not identified why some patients have these antibodies in their bodies (x,x,x).

Risk Factors for Encephalitis

rn

Anyone can develop encephalitis. However, patients with compromised immune systems may be at a greater risk. There are also regions in the United States where certain forms of mosquito-transmitted encephalitis is more common. For example, La Crosse encephalitis is most common in the upper Midwest and St. Louis encephalitis is most common in temperate areas. Eastern equine encephalitis mostly affects birds in the eastern United States and western equine encephalitis occurs in farming areas in the west and central plains.

rn

In addition, herpes simplex encephalitis type 1 is most common in patients younger than 20 and younger than 40. However, any patient can contract it. Encephalitis from genital herpes (herpes simplex virus type 2) is transmitted sexually, so lifestyle practices can affect the patients risk.

rn

Symptoms of Encephalitis

rn

Symptoms may vary based on the causes and whether the condition is infectious or autoimmune. Initially, infectious encephalitis usually causesheadachesand other symptoms similar to the flu, such as lethargy,fever, vomiting and stiffness. Then the patients symptoms usually progress and become more severe hours, days or weeks later.

rn

The most severe symptom is a change in the patients consciousness. They may simply experience mild confusion or drowsiness. The condition may be more severe and cause loss of consciousness,comaandseizures. The patient may also have sensory changes and sensitivity to light.

rn

Autoimmune encephalitis causes similar symptoms, but they may vary depending on the antibody that causes it and the symptoms may last longer. In addition to seizures, confusion and behavioral changes, patients may experience paranoia, delusions, hallucinations and sleep disturbances.

rn

Encephalitis may also affect young children and infants. Parents should pay attention to certain behaviors and symptoms that may signal encephalitis, such as stiffness, fever, vomiting and unusual irritability. The infant may also have a poor appetite and fail to wake for feedings or the parent may feel a bulge on the infants soft spot on the top of the head.

rn

Complications from Encephalitis

rn

In some cases, patients recover from encephalitis, but it is still a dangerous condition. If a patient does not receive treatment right away, it can be fatal and cause serious complications such as:

rn
    rn
  • Repeated seizures, orepilepsy
  • rn
  • Memory loss
  • rn
  • Behavioral and personality changes
  • rn
  • Speech problems
  • rn
  • Impaired physical and motor skills
  • rn
  • Vision loss

  • Movement disorders

Diagnosing Encephalitis

rn

Doctors need to perform a series of tests to confirm if a patient has encephalitis because they cannot rely on the symptoms alone, since some of them are similar to other conditions. These diagnostic tests include:

rn

Spinal Tap

rn

Also called a lumbar puncture, this procedure aims to collect sample fluid from the spinal cord by inserting a needle at the bottom of the back. Then the doctors test the fluid to find signs of infection.

rn

Brain Imaging with an MRI or CT Scan

rn

MRI and CT scans are used to find unusual changes in the brains structure. Different viral infections can infect different parts of the brain. If the doctor is able to determine which part of the brain is affected, it may help determine the kind of virus attacking it.

rn

Electroencephalograph (EEG)

rn

An electroencephalograph (EEG) attaches a small metal disc with electrodes to the patients scalp to monitor and record brain activity. Although it doesnt determine the virus that is causing it, the patterns may give the doctor an idea of the source of the infection.

rn

Blood Tests

rn

A blood test may help identify cell counts, blood chemistry and the source of inflammation.

rn

Brain Biopsy

rn

This procedure is a last resort if the doctor cannot identify a cause after several other diagnostic tests. In this procedure, the doctor collects a sample of the brain tissue and examines it for infection. However, this is not a common diagnostic option.

rn

Treatment for Encephalitis

rn

Treatment aims to either address the specific cause of the condition or to address the symptoms and complications. If a virus is the culprit behind the encephalitis, the patient needs antiviral medication. For example, a doctor may prescribe acyclovir for herpes simplex. The patient will require antibiotics for encephalitis caused by bacteria and immunomodulatory drugs for autoimmune encephalitis.

However, some types do not have a specific treatment to address the cause directly, so instead doctors attempt to address the symptom and provide support to the body. For example, a patient may need breathing assistance or a urinary or feeding tube. In some cases, a doctor may induce a coma, shutting down the brain temporarily so that it can recover from the inflammation.

rn

Rehabilitation

rn

Recovery from encephalitis may be a very long process because illnesses that affect the brain take much longer to heal than other injuries. Patients may need rehabilitation treatment to regain skills that have been impaired and manage irreversible complications. Each case is different and produces unique needs, but patients may benefit from the following types of rehabilitative therapyspeech and language therapy, physical therapy, occupational therapy and educational psychology.

rn

Supplements for Overall Health

rn

Supplements are not designed to diagnose, treat, cure, or prevent any disease, including encephalitis. However, dietary supplements may help support natural processes in the body. Always consult a doctor before adding any supplements to a dietary regimen.

rn

Omega-3-6-9

rn

Fatty acidsare a natural component of the human body. They make up all of the fat in the body and in food. When a person eats food with fat, it gets broken down into fatty acids so that the body can absorb them easier. Omega 3, omega 6 and omega 9 are just three types of fatty acids that the body contains naturally. They each have different benefits and they are present in different dietary sources. The recommended dosage foromega 3-6-9 softgelsis three softgels once or twice a day. Consult a doctor for approval before taking this supplement.

rn

Vitamin C

rn

Vitamin Cis a water-soluble nutrient with natural antioxidant properties. It is a natural part of the body that helps cells in the immune system fight foreign invaders Specifically, white blood cells use it to get rid of the disease or infection that threatens to cause damage. The suggested serving size forvitamin C/ascorbic acid powderis 1,000 mg per day. But consult a doctor before taking the supplement.

rn

Cats Claw Extract

rn

Cats claw extractis a type of vine that grows in the Amazon rain forest with thorns that look like a cats claw. The Inca civilization used it in traditional medicine practices, making it into teas and powders. Cats claw contains a compound called pentacyclic oxindole alkaloid, which acts as a natural inflammatory blocker in the body. The suggested serving size forcats claw extract powderis 500 mg one to two times a day. Talk to a doctor before taking the supplement to ensure safety.

rn

The Bottom Line

rn

Encephalitis is a condition that causes inflammation in the brain. Most often, encephalitis is caused by a virus that attacks the brain, but it may be a result of a bacteria or parasite as well. The infection may affect the brain directly or it may start in another part of the body and spread to the brain. Encephalitis may also be autoimmune, a result of antibody hormones that mistakenly attack the brain.

rn

Common viruses include herpes simplex virus, but patients can also get it through bites from infected ticks and mosquitoes. Initially, encephalitis causes flu-like symptoms, which may range from mild to severe. The most severe sign is a change in the patients consciousness. They may suffer mild confusion, seizure or coma. Encephalitis may also affect the patients motor skills, speech, memory and behavior.

rn

Without prompt medical attention, encephalitis can be fatal. Treatment like antibiotics, antivirals and immunomodulatory drugs aim to address the immediate cause. But other treatment methodssuch as ventilators, feeding tubes and induced comaaim to address the symptoms and complications. The recovery process may be very long and difficult and patients may need rehabilitative assistance to help manage the complications.

rn

People may also take supplements to keep the body healthy. However, they do not diagnose, treat, cure or prevent any disease. Supplements are not an adequate replacement for legitimate medical advice. These statements have not been evaluated by the Food and Drug Administration. Consult a doctor before taking supplements.
