While the symptoms may start out resembling those of a cold or upper respiratory infection, they can quickly become more severe. Encephalitis is usually caused by a virus, such as the herpes simplex virus types 1 and 2, or arboviruses, in the United States. Arboviruses are spread from animals to humans and causes mosquito-borne disease. An example is the West Nile virus.

Symptoms may start out as mild flu-like symptoms and headaches, quickly followed by behavioral changes, hallucinations, and confusion. Some forms of bacterial meningitis and encephalitis are contagious and can be spread through contact. For example, meningococcal meningitis is easily spread among people who live together such as college students in a dormitory.

If you have recently been in contact with someone who has been diagnosed with bacterial meningitis or encephalitis, talk with your doctor to find out if you need prophylactic antibiotics, which can help prevent a bacterial infection. The spinal cord is responsible for carrying sensory information back to the brain and motor messages from the brain to the body.

When it is inflamed like in the case of myelitis , symptoms can include pain, weakness in the limbs, bowel and bladder problems, and sensory problems. Many people with myelitis also experience muscle spasms , headache, fever, and loss of appetite. Myelitis may be related to an immune disorder or infection from a virus, bacterium, fungus, or parasite. Most people who experience myelitis make a full recovery, but the process can take months to years.

There is no cure for myelitis, but the symptoms can be treated. A brain abscess occurs when a collection of pus becomes enclosed in brain tissue.

This rare condition can be caused by a bacterial or fungal infection, and is also a possible complication of surgery or trauma. People with compromised immune systems are more at risk of having a brain abscess. Symptoms include a high fever, severe headache, behavior changes, and nausea and vomiting.

Over time, an abscess can cause changes in speech, motor weakness, spasticity, and seizures. Once it is discovered, an abscess must be located and surgically drained, followed by four to eight weeks of antibiotic therapy.
