Thomas Addison first identified the disease in 1855 while working at Guy's Hospital in London. At that time, the main cause of the disease was as a complication of tuberculosis. TB still remains an important cause of Addison's in Third World countries. HIV (AIDS) is now becoming another significant infectious disease causing adrenal failure among third world population.
In more affluent countries, the most frequent cause of Addison's disease is destructive atrophy whereby an over-active immune system starts attacking the body's own organs; in this case, the adrenals. This accounts for around 70% of all cases and affects more women than men. In common with most other autoimmune diseases, the exact reason for the atrophy is unknown.
Other, much rarer causes of Addison's include certain fungal infections, adrenal cancer and adrenal haemorrhage (for example, following a car accident).
A pathogen causes infectious disease. For instance, influenza virus is the pathogen that causes flu.
Pathogen
Any pathogen causes disease. Which disease depends on which pathogen.
Pathogen
A pathogen is a microorganism that causes disease such as bacterium and viruses. All viruses are pathogens, which means they all cause disease it causes disease But a pathogen is a living organism and a viru s is not so its really argumentive.
A disease causing organism is called a pathogen.
Pathogen is the agent or the culprit that causes a disease while the disease is the end result of what a pathogen did. Example: HIV virus is the pathogen while AIDS is the disease state that can result from high HIV viral load.
A pathogen causes a disease while a contagion spreads a disease by direct or indirect contact.
Pathogen is the agent or the culprit that causes a disease while the disease is the end result of what a pathogen did. Example: HIV virus is the pathogen while AIDS is the disease state that can result from high HIV viral load.
A microorganism is called a "pathogen".
it causes other diseases
any microorganism that causes disease.
