A set of mental diseases in which a person knowingly feigns an illness and its symptoms. People suffering with factitious disorder may lie about their symptoms, change diagnostic tests, or even harm themselves in order to elicit symptoms.

Factitious disorders are classified into four categories according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV).

The Top 4 Factitious Disorders Categories

  • Psychological symptoms dominate this factitious disease.
  • Mostly physical signs of a fictitious disorder.
  • Psychological and bodily manifestations of a fictitious condition
  • Other than that, it’s a fictitious illness.

Unlike somatization condition, where the person genuinely experiences the symptoms, factitious disorders are defined by the person purposefully simulating the symptoms of the illness without truly experiencing it.

This disorder can be caused by a history of neglect, abuse as a kid, or long-term sickness in close family members.

  • Fregoli delusion: People who suffer from Fregoli delusion believe that a single person disguises himself and appears as various people to punish them. Some of the frequent symptoms of this disease include hallucinations, trouble retaining visual recall, delusions, and a loss of self-awareness and monitoring.
  • Somatization Disorder, commonly known as hysteria or Briquet’s condition, is a type of somatization disorder. It is characterized by persons frequently complaining of discomfort caused by particular conditions despite the absence of medical evidence or a physical cause.

In this situation, the person is aware of the condition’s symptoms and even feels the discomfort it causes. People with chronic pain or irritable bowel syndrome are more likely to develop this condition.

  • Shared psychotic disorder, also known as folie á deux, occurs when an otherwise healthy individual begins to believe in the delusional views of a psychotic person with whom he or she has a close relationship. This is a highly rare occurrence that only occurs in very long-term relationships.
  • Substance Abuse is defined as the hazardous use of psychoactive substances such as drugs, tobacco, and alcohol, which leads to a reliance on these substances. Even though the person is aware of the substance’s dangers, he or she continues to use it.


This list of mental illnesses has attempted to include the mental disorders that are generally recognized by psychiatrists and health professionals around the world. But it is not exhaustive.

Some of these mental diseases, as well as their symptoms, may fall into multiple categories. What’s vital is to be aware of these mental health problems’ warning signs.

Assessment of the situation and prompt treatment, whether in the form of counseling or medication, can assist to avert a serious and debilitating psychiatric problem.

Hi, I'm Laura and welcome to my blog.

I've been interested in the human mind since I was a child and that's the reason why I became a psychologist. I thought I had everything figured out, but it turned out I was suffering from anxiety for at least ten years without even noticing it. With the help of what I already knew, and some of my friends/colleagues, I compiled a list of articles that helped me go through my anxiety and get to the other side of the tunnel.

Thanks for stopping by, and I hope you find something to help you along the way.
