Abstract
For this paper I will be discussing a homeostatic imbalance of the nervous system called Encephalitis. Encephalitis is inflammation of the brain mostly caused by viral infections and some bacterial. (Mayo Clinic Staff, 2012) It occurs in approximately 0.5 per 100,000 individuals with it most commonly occurring in people with weakened immune systems, the elderly, and children. (Howes, 2013). A person infected will have headaches, a fever, body aches, and experience fatigue or weakness. Encephalitis is diagnosed by examination and tests by a doctor. The doctor may check for neck stiffness, muscle weakness, mental confusion, and speech problems. These examinations may not provide enough information on Encephalitis so the doctor may order certain tests to confirm the diagnosis. Depending on the severity of the illness treatment of Encephalitis can usually be healed with bed rest, fluids, and anti-inflammatory drugs. When the illness is diagnosed it is hard to tell what kind of last affects the Encephalitis will have. Even though there is many different treatments and courses of action in diagnosing and treating Encephalitis there is no guarantees of what exactly will happen. Encephalitis can a very serious infection and can have serious lasting affects on the brain. So in conclusion it is important to know the symptoms, affects, treatment, and diagnosis of Encephalitis because it can happen to anyone at anytime.

The human body and its’ organ systems work in incredible ways to stay balanced so we can function on a day-to-day basis this is called homeostasis. Homeostasis is the tendency of a physiological system to maintain internal stability responding to any stimulus that may disturb any normal function. (Dictionary.com, 2013) If anything enters the body to cause an imbalance the body quickly tries to fight off this intruder. For this paper I will be discussing a homeostatic imbalance of the nervous system called Encephalitis. Encephalitis is inflammation of the brain mostly caused by viral infections and some bacterial. (Mayo Clinic Staff, 2012) It occurs in approximately 0.5 per 100,000 individuals with it most commonly occurring in people with weakened immune systems, the elderly, and children. (Howes, 2013) Encephalitis is very unpredictable and is not the same for each person. Most people infected with a mild case of encephalitis have mild to no symptoms and the illness does not last long however more serious cases have more serious symptoms and greater effects on the body including speech and activities of daily living. Encephalitis is a rare condition that is most common in infants and the elderly; it is most common in infants in the first year of life. (Green, 2013) The younger the infant the harder the symptoms are to detect. Mostly caused by viral infections like measles, mumps, polio, chicken pox, and west nile virus but can be caused by allergic reactions to vaccinations, an autoimmune disease, some bacteria, like Lyme disease and syphilis, and the effects of cancer. (Green, 2013) The virus causes inflammation when brain tissue gets inflamed which may cause cells to be destroyed, bleeding of the brain, and worst-case brain damage. (Kaneshiro, 2012) Encephalitis is different for each person affected so it is very important to get a quick diagnosis and treatment. Just like the condition itself the symptoms of Encephalitis is different for each person. In most cases the infected person will feel mild flu-like symptoms or no symptoms at all. A person infected will have headaches, a fever, body aches, and experience fatigue or weakness. Obviously the more serious the swelling the more serious of symptoms a person is going to experience so in serious cases the person will have a more severe headache, higher fever, disorientation including hallucinations and mood swings, problems with...
