For many years, abnormal behavior has been frowned upon. They were overlooked and no one ever stopped to investigate what was causing these behaviors and whether any of these unusual behaviors had a deeper meaning than simply categorizing them as unacceptable norms. The purpose of this article is to reveal a disorder that is found in people all over the world. Multiple Personality Disorder (MPD) known today as Dissociative Identity Disorder (DID). The disorder is described as the existence of multiple identities and personalities in a person that take over an individual's conscious mental state. In the course of the article, the cases of two girls Félida and Lucie who are dealing with split identities will be discussed, the history and introduction of DID in cinema will be analysed, as well as the causes, symptoms and who the psychological disorder affects.

Get an Original Essay In the late 1800s, a case sparked controversy over whether two sets of identities could exist within one person. The case was known as the “Félida X case”. The case involved a young teenager named Félida who suffered from a double identity. The study was documented by surgeon Etienne Eugéne Azam who stated that Félida suffered from constant headaches and seizures. He tended to fall into a long, deep sleep. However, when he woke up from these sleep states, he would have a particular personality, unique and completely different from the one he had before falling asleep. The new personality was cheerful and frivolous and loved to play pranks, unlike the pre-sleep Félida who was more serious and reserved. It is a case like this that has sparked a dispute between the “unconscious second self” (Brown, 2003). Pierre Janet, one of the founding fathers of psychology, intrigued by the concepts of the second personality, also conducted his study with a 19-year-old patient named Lucie. During the study, Janet focused on resolving Lucie's hysteria. He used hypnosis, which is when a person is in a state of consciousness but eventually loses the power of voluntary actions and responds only to orders given by the hypnotist. Lucie often performed various tasks after waking from hypnotic sleep, which she later did not remember doing. Janet predicted that Lucie had another identity within her, so she decided to try something new. Janet stood behind her and asked her questions while Lucie conversed with someone else. He responded to his interrogations by writing sentences on paper. After she finished writing what she had answered Janet, she denied completing the task because she was unaware that she had, in fact, answered the questions he had asked her. The second person who had performed this "automatic writing" was later named Adrienne, Lucie's second identity. The two personalities were far from similar. Adrienne was considered a "healthier" person than Lucie, considering she did not experience the hysteria that Lucie was subjected to on a daily basis. In the end it was therefore Pierre Janet's various studies that later confirmed the discovery of "dissociation" disorders in the context of in-depth research on other topics (Brown, 2003). These cases were able to provide evidence that the abnormal behaviors were not just actions exhibited by a crazed person, but rather symptoms that people experience when suffering from a dissociative disorder. Looking back to long before the cases of Félida and Lucie, abnormal behaviors were linked to supernatural deviances or were seen as a disease that infected the bloodstream of thehuman body. Many believed that people suffering from psychological disorders had a demon possessing their bodies or that they were tormented by the gods. It was not until the 20th century that research was conducted and psychological disorders were classified and later declared as part of “Multiple Personality Disorder” (MPD). The disorder, however, was later renamed “Dissociative Identity Disorder,” DID, by the American Psychiatric Association in 1994 (McDavid, 1994). Additionally, due to the attention that DID has managed to gain, films and plays have also had a huge impact by providing insight into dissociative disorder. A film like Three Faces of Eve revived interest in multiple personality disorders in the late 1950s. The film illustrated an actress who played the role of a woman named Eve White who suffered from having various multiple personalities and often changed her name to Jane and Eve Black. In the film, she, like many patients suffering from DID, had headaches and other symptoms that consisted of fainting and memory loss. The misfortune of not being able to remember affected his daily life as he was unable to remember what he had done during the day. Although it took decades before this disorder was recognized, eventually, thanks to studies conducted by psychologists and films like this, it was possible to identify and change the minds of many. So, what causes DID? Who does it hit? And what symptoms accompany the disease? First, the development of this disorder is caused by traumatic situations such as physical or sexual abuse, abandonment by a parent and involvement in an accident. In the Journal of Mental Health Counseling, by Lamerial Jacobson et al., it is stated that approximately 71% of patients with DID suffered physical abuse in childhood and approximately 74% suffered sexual abuse (Hallet, 2015). ). The complication is known to develop before the age of seven and is diagnosed primarily in women due to a higher rate of sexual abuse and incest occurring more often among women than men. Some of the symptoms of DID are forgetting memorable experiences and losing recognition of traumatic incidents. Some may also develop depression and anxiety, as well as eating disorders or addictions. Patients with the complication have been found to behave hostilely or behave erratically by altering their tone of voice, shifting body movements, and making unusual facial expressions. However, to date no permanent cure has been found for recurring split personalities. However, symptoms can be treated through intense psycho, behavioral, family, and hypnotic therapies. Normally, during the process, doctors allow patients to understand and learn about their multiple personalities so that they can further learn how to regulate their emotions and behaviors. In this way, doctors are improving the effects of amnesia, since people with DID are unaware of their identity. Ultimately, the host's ultimate goal is to find a way to integrate all the personalities that reside within themselves to have a unified whole. Please note: this is just an example.

Many people are unfamiliar with dissociative identity disorder and fail to recognize abnormal behaviors as part of a chronic illness. People are often ignorant. Instead of trying to find out what makes a person act a certain way, they would rather stereotype DID patients as demented lunatics. Not, 93(3), 477-500.
