What is borderline split personality disorder?


Split Personality Disorder (SPD), previously called Multiple Personality Disorder (MPD) and now widely referred to as Dissociative Identity Disorder (DID), is a mental illness in which a person has traces of several personalities within the same body.

These personalities are also referred to as alter egos or alters, each of which has a pattern of their own. That is, their mannerisms, perceptions and interactions with the environment are specific to that personality.

These personalities are like separate people existing in one body. Although these alters might share certain traits with the host body, they do not know the existence of the other personalities within that body.


Split personalities are said to result from severe stress and trauma that a person suffers from (usually in his/her childhood).

One of the main causes is suffering repeated emotional, sexual or physical abuse as a child and the lack of people who can act as comforting factors to counteract that abusive relationship.

They also have an innate ability to dissociate themselves easily so that they do not have to deal with the trauma they suffer.


Following are some split personality disorder symptoms in children that only grow with time:

  • Depersonalization: the patient  feels that his body is not his own.
  • Derealization: the patient sees the external environment as unreal, e.g. see objects changing their shape and size and might not even recognize people and relatives.
  • Amnesia is experienced quite commonly by DID patients. They report having gaps in their memory at a time when the other personality is out, whereby, they cannot remember certain incidents or sometimes complete details of their condition.
  • Prone to unreasonable anger.
  • Hallucinations.
  • Sudden and intense mood changes .

Consult a doctor to clarify the disorder symptoms and seek necessary treatment immediately.
