Transcript of Homeostasis (Meningitis)

Upsetting the Balance HOMEOSTASIS Disease of the Brain & Spinal Cord HISTORY Meningitis Hippocrates was an ancient Greek physician who discovered the existence of meningitis (460BC-370BC). Overtime, a Scottish physician named Robert Whytt described “drowsy of the brain” in a posthumous report. Although he discovered this condition of sickness, it was unknown of the cause and what other sicknesses were similar to it. Soon in 1845-1920 an Austrian pathologist and bacteriologist Anton Weichselbaum found the cause of meningitis which was bacteria Symptoms Symptoms of meningitis are easily mistaken for the symptoms of the flu, but symptoms of meningitis may develop over hours or even days. Causes Meningitis is caused by infections from viruses or microorganisms. It also disrupts the body’s homeostasis by affecting the immune and nervous system. There are four types of meningitis infections, which are bacterial, viral, chronic, and fungal. But the main ones include bacterial and viral. Effects on Homeostasis It is usually the job of the human body’s immune system to fight off infections or sometimes it is able to contain them. But once the infection passes through the bloodstream towards the brain and spinal cord, not only can it affect the nerves (nervous system) traveling around the brain and spinal cord but it can also cause inflammation and swelling which then leads to meningitis. Treatments Treatments for Bacterial Meningitis include antibodies entering the veins, but the antibiotics given by the doctor are according to the type of bacterial infection. Chronic meningitis due to a fungus is usually treated with antifungal drugs given intravenously or by mouth. Amphotericin B, flucytosine, and fluconazole are used most often Meningitis is an inflammation of the membranes surrounding the brain and spinal cord which swells up due to the spread of infection. Ages 12 & Over: High Fever

Vomiting or nausea with headache
Difficulty concentrating
Seizures
Sensitivity to light
Sleepiness or difficulty waking up Newborns: Constant crying
Sleepiness or irritability
Inactive or sluggishness
Poor feeding

Bacteria can also directly invade the meninges aka the membrane of the brain and spinal cord Viral Viral Meningitis is not severe as bacterial meningitis and is able to clear up on its own. It is occurred by a group of viruses called enterovirus. This type of meningitis tend to happen during late summer early fall. It is basically a seasonal sickness. Chronic Chronic Meningitis occurs when small organism grow around the membrane and fluids of your brain. This type of meningitis is rare. Fungal Fungal Meningitis is uncommon but causes chronic meningitis . It can also mock bacterial meningitis and can be life threatening if not treated. This means that the immune system failed at sending white blood cells towards pathogens or failed at developing immunity causing the nerve system to respond incorrectly and receive the wrong message from blood. Due to the wrong message, it causes the brain to become damage. The immune system basically interfered with the nerve system by stopping it from controlling/regulating parts of the human body correctly. Viral Meningitis is known to be mild and would not necessarily need antibodies. Instead the doctor would recommend bed rest, plenty of fluids, and pain medication to help reduce fever and relive body aches. Fungal Meningitis is treated by:

Antifungal medicine: helps kill the fungus causing your infection.
Fever medicine: This medicine lowers your temperature. Common medicines used to lower temperature include acetaminophen and ibuprofen.
Steroids: This medicine may be given to decrease inflammation.
Antinausea medicine: This medicine may be given to calm your stomach and prevent vomiting.
