Dissociative identity disorder is formally called multiple personality disorder. It is the mental illness in which two or more distinct identities exist in one person that causes disruption or break down of memory, awareness, identity, emotions, sense of self or perception.

 People with DID experiencing a disconnection and lack of continuity between thoughts, memories, actions and identity. People with multiple personality develop one or more alternate personalities that function with or without the awareness of person’s usual personality. They often feel as multiple voices or people reside in their head. They behave as they possess 2 or more selves, each with its own characteristics, moods, and memories.

Dissociation is often thoughts as a coping mechanism that a person uses to disconnect from a stressful situation or experience that’s too violent, painful to assimilate with their conscious self. It is a way for a person to break the connection with the outside world, and create distance from an awareness of what is occurring.

Those who experience DID feel detached from themselves as if they are outside observers of their experience when they have a dissociative episode. The episodes of DID can be triggered by a variety of real and symbolic traumas including mild events such as being involved in a minor traffic accident, adult illness, or stress or a reminder of childhood abuse.

Multiple personality disorder has been difficult to understand, difficult to diagnose and difficult to treat

Causes of DID:

  1. Trauma is main cause of dissociative identity disorder.

A history of trauma is a key feature of multiple personality disorder. The trauma often involves severe emotional, physical or sexual abuse. It might be also linked to accidents, natural disasters and war.

  • The syndrome of DID is associated with a high incidence of physical or sexual abuse in childhood. About 90% of the cases involve history of abuse. MPD may be cause due to reminder of childhood abuse for a parent may be when their child reaches the same age at which the parent was abused.
  • Research indicates that the cause of DID is likely a psychological response to interpersonal and environmental stresses, particularly during early childhood.

DID is difficult and complicated to diagnose both because of the nature of syndrome and because of professional reluctance.

It is estimated that individuals with DID have spent seven years in the mental health prior  to accurate diagnosis. DID is diagnosed in a multitude of ways, it take times to diagnose DID. Misdiagnosis is common, a doctor needs to observe a person’s symptoms, and dismiss other conditions.

Additionally as often occur alongside other disorders, doctor need to rule out the symptoms of other conditions before they make a diagnosis
