Dissociative Identity Disorder - DID

"Multiple personality disorder" "多重人格 " is a mental disorder...It is also called Dissociative Identity Disorder (DID)...

According to statistics, 0.01% to 1% people in the world have this disorder. A person who has 2 or more distinct personality states, each personality states have their own individual emotions, attitude, memory, responses and social behaviour...Its like having multiple souls in single body, taking turns to control the same body...But, DID is not schizophrenia, schizophrenia is more likely to refer to disorder of a person's cognitive and sensory process...It is the splitting between one's perception and the reality. In contrary, DID includes all kinds of split personality, it can be different genders, occupation, age, race and even species. They take turns to control the patient's behaviour from time to time...

.

There are two situations of split personality. One is that the splited personality is aware of each others' existence, which is known as "consciousness coexistence", if this "CC" relationship is strong, they can even communicate with each other... They may communicate internally through their consciousness, or through external communication by talking it out...The external communication between split personalities, would look like a lunatic talking to himself. The other situation is that all personalities remain mutually unaware of the others' existence, Thus leading to so-called "time loss" phenomenon...When the subordinate personalities control the body, the host personality is completely unaware and the memories regarding what happens during this time is lost...The usual forgetfulness of normal people as if a memory is hidden in a huge folder, it may still be found after recalling back the memory, with some effort. DID is not caused by substances, so this is not like the babbling state when you are drunk, or the psychological effects, trauma of a general medical condition or incidents...

.

Most people think DID is related to childhood trauma...Because childhood is the stage of developing personalities, when one has experienced a traumatic event in order to protect himself he may "space out". The original personality is the personality before the appearance of other personalities, but the host personality is the personality the dominates the body most part of the time. Although the original personality is usually the host personality, but there are also cases where the original personality is still left in the childhood period... the control of the body has been passed over to the host personality who is more mature. . In addition, according to neurological research, despite being the same person with the same brain, different personalities yield different encephalogram results...So this strongly prove that DID is not sth you can disguise.
