The main character is a doctor, with highly valued morals and intelligence. Loved by everyone around him and well known for his soft heart, Dr. Jekyll discovers a poison that allows him to radically change his personality. After trying it on himself, Dr. Jekyll's body is possessed by an evil genius, Mr. Hyde. He is a monster and does not shy away from anything.
Robert Louis Stevenson, as a great effect, used the appearance of a split personality in a great work of science fiction, "Doctor Jekyll and Mr. Hyde", 1886.
One of the most severe disorders that can be encountered in psychological practice is dissociative personality disorder, also known as multiple personality disorder. Namely, it is about the existence of different personalities (or identities) in one person, each of which, when present, can dominate attitudes, behavior and emotions as if other personalities do not exist.
The main characteristic of borderline personality disorder is high instability in interpersonal relationships, self-image and emotions. People with this personality disorder are usually very impulsive.
Split personality in children begins quite early, and most often it was sexual or physical abuse that has been shown to be the cause in slightly less than 60% of cases of split personality. Namely, these traumatic experiences can lead to a person having to separate the emotions of fear and pain that he felt. The need for separation will then lead to the unconscious separation (dissociation) of different aspects of the first person, where each of the persons will show some emotion: anger, sexuality, adequacy that the first person did not have the strength to express.
It is often difficult for them to admit to themselves what has happened and they suppress such traumas so as not to persecute them.
When the American psychiatrist Morton Prince published his book 'The Split of Personality' in 1905, his European colleagues hardly deserved his attention.
This extraordinary report on the clinical diagnosis of a multiplied personality was treated as a sensationalist novel. More attention was paid to this disorder only 50 years after the publication of Prince's book.
Namely, in the book 'Three Faces of One Eve', psychiatrists C.H. Tigpen and H.M. Chekli describe the tragic fate of a twenty-five-year-old woman with three different personalities. White Eve, Black Eve and Jane act independently of each other and each of them is unaware of the existence of the other two. Voice, IQ, handwriting, and even electrical activity tests of the brain vary depending on the personality expressed.
White Eve was a quiet, calm, dignified woman with conventional understandings and behaviors.
Black Eve, in contrast, was debauched, flirtatious, and reckless.
Jane the third person appeared during the therapy. She was more mature than the other personalities.
These three personalities were completely different and yet physically the same. When someone would look at Eva, they would see one person behaving differently in different situations.
The symptoms of a split personality often seem frightening, and it is still not clear to many how a person can represent one person for a moment and another for a moment.
depersonalization, a feeling of unreality and separation from one's own physical and mental states,
derealization, familiar environments and people are no longer known,
vague and incomprehensible changes in behavior,
rapid emotional changes,
constant changes in opinions and attitudes,
lack of self-awareness,
difficult orientation in time and space,
lack of insight into one's own life and condition,
lack of self-esteem and withdrawal,
avoiding talking about problems,
talking about oneself in the third person singular,
suicidal thoughts and suicide attempts,
self-harm.
People who have a split personality most often hear voices that appear to be internal conversations between multiple people addressing the patient.
The Secret of the Split Personality Little Me, Little He. One of the most serious mental disorders is multiplied personality. This means that one person unites several completely different characters. Even today, psychiatrists have trouble explaining the existence of multiple ‘I’. But isn't that sometimes expressed in normal healthy people as well.
