Fabricated or Induced Illness
Fabricated or Induced Illness is sometimes more commonly known as Munchausen Syndrome or Munchausen Syndrome by Proxy.
This disorder is known as the disorder that makes people deliberately, and sometimes very gradually, inflict injury on themselves (Munchausen Syndrome) or injury or illness on somebody in their care (Munchausen Syndrome by Proxy) usually in an effect to gain attention.
People with this disorder that inflict these illnesses on others commonly do-so to their children of their parents that are aging and need care. Sometimes rather than the inflicting physical illness, they are also known to inflict mental abuse in order to achieve apparently psychiatric help.
It is imperative that sufferers of this disorder get treatment, as it has in many cases wound up as murder or suicide. Either intentional or as a result of long-term low level poisoning or other methods to induce illness builds up in ones body, especially in children, ends up being fatal.
Reasons for doing this seem to often stem from the person simply needing attention or needing to have their worth validated, as they are now "needed" to care for these poor, ill people.
People with this disorder can be noted by a few tell-tale keys from their behavior. If themselves, or their dependents that are kept ill, seem to always be ill, and never seem to respond to standard treatments for the illnesses being diagnosed with. They often are very medically knowledgeable, and very much seem to enjoy the hospital environment and enjoy hospital gossip and stories. They are often seen as hovering, ever present parents, scared to ever leave their children's (or ill dependents) side. They often require constantly kudos and pats on the back and go to the ends of the earth for public acknowledgments of their self-serving efforts.
The people these disorders afflict are usually women if the illnesses are given to a dependent, mostly men if the illnesses are inflicted on ones self.
