control, and the person may use faked symptoms and a fabricated medical history to gain back a sense of autonomy. Those with factitious disorder are also more likely to have experienced a severe illness in childhood, with the early exposure to healthcare being a major contributor to the onset of the disorder. There is a significant correlation found between the comorbidity of factitious disorder and personality disorders, specifically borderline personality disorder. Depressive disorders are also often diagnosed concurrently with factitious disorder. The causality cannot be known about whether one disorder causes the other, but it can be deduced that these diagnoses share similar etiologies and some overlapping symptoms. Each particular case of factitious disorder presents itself differently and is derived from various etiologies. However, there is an overarching belief that patients experience the uncontrollable urge to maintain the sick-patient role, acting as a type of behavioral addiction. This contributes to the prolonged behaviors associated with the disorder. Diagnosis Criteria for diagnosis include intentionally fabricating to produce physical or psychological signs or symptoms and the absence of any other mental disorder. Motivation for their behavior must be to assume the "sick" role, and they do not act sick for personal gain as in the case of malingering sentiments. When the individual applies this pretended sickness to a dependent, for example, a child, it is often referred to as "factitious disorder by proxy". The DSM-5 differentiates among two types: Factitious disorder imposed on self (Munchausen syndrome) Factitious disorder imposed on another (Munchausen syndrome by proxy), defined as: When an individual falsifies illness in another, whether that be a child, pet, or older adult. Factitious disorder imposed on self Factitious disorder imposed on self, previously called Munchausen syndrome, or factitious disorder with predominantly physical signs and symptoms, has specified symptoms. Factitious disorder symptoms may seem exaggerated; individuals undergo major surgery repeatedly, and they "hospital jump" or migrate to avoid detection. Factitious disorder imposed on another Factitious disorder imposed on another, previously Munchausen syndrome by proxy, is the involuntary use of another individual to play the patient role. For example, false symptoms are produced in children by the caregivers or parents, to produce the appearance of illness, or they may give misleading medical histories about their children. The parent may falsify the child's medical history or tamper with laboratory tests to make the child appear sick. Occasionally, in Munchausen by proxy, the caregiver actually
