Meningitis

Meningitis

Meningitis
The two most important parts of the Central nervous system is embraced by a fibrous connective tissue, the meninges. It provides protection, support and nourishment.  There are three layers of the meninges, the dura mater contains spaces which collect blood from the small veins of the brain. The arachnoid’s crucial function is the production of cerebrospinal fluid. The last most inner layer, the pia mater, tightly bounds the surface of the brain and the spinal cord.
  When this fibrous connective tissue becomes inflamed, the condition is called as meningitis.
The condition may be caused by either a virus or a bacteria that are successfully able to cause infection.  Bacterial meningitis is observed to be worse cases than viral meningitis. It can also be caused be a fungus particularly in the case of HIV-AIDS inflicted patients. The type of fungus can usually be driven off by the body's immune system but since they are immunosuppressed, the fungus  is able to cause a severe infection to patients. The most common symptoms include stiffness in the neck, headache and fever. Other symptoms include nausea, vomiting, mental status changes and seizures. There are cases that the symptoms are not taken care of or does not immediately seek intervention of a medical doctor thus causing greater problems such as paralysis, coma and death.  
The patient may undergo lumbar tap, aspiration of CSF from the lower part of the spine then be sent to a laboratory, for the diagnosis of Meningitis can only be confirmed by a CSF analysis.

  1. The most common symptoms of meningitis are headache and neck stiffness associated with fever, confusion or altered consciousness, vomiting, and an inability to tolerate light (photophobia) or loud noises (phonophobia). Children often exhibit only nonspecific symptoms, such as irritability and drowsiness. If a rash is present, it may indicate a particular cause of meningitis; for instance, meningitis caused by meningococcal bacteria may be accompanied by a characteristic rash.
