Glossary for Headache

Medical terms related to Headache or mentioned in this section include:

  • AIDS: A term given to HIV patients who have a low CD4 count (below 200) which means that they have low levels of a type of immune cell called T-cells. AIDS patients tend to develop opportunistic infections and cancers. Opportunistic infections are infections that would not normally affect a person with a healthy immune system. The HIV virus is a virus that attacks the body's immune system.
  • Abscess: This is an area of puss collected in a cavity which is constituted by necrotised tissue
  • Acanthamoeba infection: Infection with a microscopic, free-living ameba that is readily found in the environment - soil, air and water. Most people exposed to the ameba will not become infected but when infections do occur, they tend to affect the eyes, central nervous system or can cause widespread infection throughout the body.
  • Acanthamoeba infection of the central nervous system: Infection by an amoebic organism called Acanthamoeba. Infection usually occurs when the amoeba enters through a break in the skin or through the nose. Infection can be localized or systemic where it can involve the central nervous system and cause potentially fatal meningoencephalitis. Infection of the eye can occur by cleaning contact lenses in contaminated water.
