syndrome by proxy (MSBP) is a mental health problem in which a caregiver makes
up or causes an illness or injury in a person under his or her care, such as a child, an elderly adult, or a person who has a disability. Because vulnerable people

child abuse or elder abuse.
Note: Since most cases of MSBP are between a
caregiver (usually a mother) and a child, the rest of this topic will describe that relationship. But it is important to remember that MSBP can involve any vulnerable person who has a caregiver.

abuser's childhood. Abusers often feel like their life is out of control. They
often have poor self-esteem and can't deal with stress or anxiety.
The attention that caregivers get from having a sick child may encourage
their behavior. Caregivers may get attention not only from doctors and nurses
but also from others in their community. For example, neighbors may try to help
the family in many ways—such as by doing chores, bringing meals, or giving

What are the clues that a person may have Munchausen syndrome by proxy?
Checking a child's medical records for past tests, treatments, and hospital stays may help a doctor or nurse find out if a health problem is real.
Doctors or nurses may suspect a problem when:
