Definition
Factitious disorder is a mental illness in which a person makes up an illness or injury. This is done for emotional reasons. The person may want attention and care. It is not done for money, food, or housing.
There are two types:
- The person claims to be sick or injured
- A parent claims their child is sick or injured —factitious disorder by proxy (Munchausen syndrome by proxy)
