Dissociative identity disorder (multiple personality disorder )

Dissociative identity disorderDissociative identity disorder (DID), recently known as multiple personality disorder (MPD), is a dysfunctional behavior characterized by at least two distinct and moderately lasting character states. It is described by disassociation, or an interruption in the incorporated consciousness of self, personality, memory, and perception. This is joined by memory gaps that might be clarified by common forgetfulness. Other issues that regularly happen in individuals with DID are borderline personality disorder (BPD), posttraumatic stress disorder (PTSD), substance use disorders, depression, self-harm, and anxiety.

The disorder has been broadly examined, however, results are frequently conflicting—it stays hard to diagnose, no reasonable reason is distinguished, and treatment is effective but sometimes complicated. 

It is believed that dissociative identity disorder influences about 1.5% of the overall public (in light of a little US people group test), and 3% of those admitted to clinics with psychological health issues in Europe and North America. DID is diagnosed around multiple times more regularly in females than males. The number of cases expanded essentially in the last 50% of the twentieth century, alongside the number of personalities asserted by those influenced. 

There are two definitions for specific cases that can help in the observation of the disorder: “possession” and ”non-possession” cases. Possession cases, where interchange characters were effectively seen by others. Non-possession cases, where exchanging between interchange characters didn’t happen for broadened timeframes, or changes in peculiarities and practices were slight or unnoticeable.


The reason for DID is obscure and broadly discussed, with the discussion happening between supporters of various theories: that DID is a response to trauma; that DID is created by improper psychotherapeutic techniques that cause a patient to sanction the job of a patient with DID. 

A few experts accept the reason to be childhood trauma. The trauma involves severe emotional, physical, and/or sexual abuse. In about 90% of cases, there is a background marked by abuse in childhood, while other cases are connected to encounters of war or medical issues during childhood. Genetic variables are likewise accepted to play a role. 

Disturbed and modified sleep has additionally been suggested as having a place in dissociative identity disorder as one of the reasons. Natural disasters also might cause a DID. 

A significant early loss, for example, the loss of a parent or delayed times of confinement because of disease, might be a factor in creating DID. 

Dissociation is frequently thought of as a method for dealing with stress that an individual uses to disengage from an upsetting or horrendous circumstance or to isolate awful recollections from normal mindfulness. It is a way for an individual to break the association with the outside world, and create distance from attention to what is happening. 

Dissociation can fill in as a safeguard system against the physical and emotional pain of a horrendous or distressing background. By separating excruciating recollections from regular perspectives, an individual can utilize dissociation to keep up a general way of life, as if the trauma had not happened. 

Scenes of DID can be activated by an assortment of genuine and emblematic traumas, including mild occasions, for example, being engaged with a minor car crash, adult illness, or stress. Or on the other hand, a token of childhood abuse for a parent might be the point at which their kid arrives at a similar age at which the parent was abused.

Signs and symptoms

As indicated by the fifth Diagnostic and Statistical Manual of Mental Disorders (DSM-5), DID symptoms incorporate “the presence of two or more distinct personality states” joined by the powerlessness to recall individual data, past what is normal through ordinary forgetfulness. Other DSM-5 symptoms include a loss of identity as associated with individual distinct character states, and loss alluding to time, feeling of self and consciousness. 

The individual may encounter amnesia when an alter assumes responsibility for the individual’s behavior. 

Each alter has particular individual qualities, an individual history, and a perspective about and identifying with their environment. An alter might be of alternate sex, have an alternate name, or a distinct arrangement of habits and inclinations. (An alter may even have unexpected hypersensitivities in comparison to a profound individual.) 

The individual with DID may or may not know about the other character states and recollections of the occasions when alter is prevailing. Stress, or even a token of trauma, can trigger a switch of alters.

In some cases, the individual with DID may profit by a specific alter (for instance, a modest individual may utilize an increasingly decisive alter to arrange an agreement). All the more frequently DID makes a disorganized life and problems in personal and work relationships. For instance, a lady with DID may more than once meet individuals who appear to know her whom she doesn’t recognize or recollect regularly meeting. Or then again she may discover things around the home that she doesn’t remember purchasing. 

DID shares numerous mental symptoms as those found in other mental issues, including: 

  • Changing degrees of functioning, from exceptionally successful to aggravated/debilitated 
  • Serious migraines or pain in different parts of the body 
  • Depersonalization (feeling detached from one’s very own thoughts, emotions, and body) 
  • Derealization (feeling that the surrounding environment is remote, odd, or unreal) 
  • Depression or potentially emotional episodes 
  • Anxiety
  • Substance abuse
  • Eating and sleeping disorders
  • Issues with functioning sexuality
  • Amnesia, hallucinations 
  • Self-damaging practices, for example, “cutting”.


Making the diagnosis of dissociative identity disorder takes time. It’s estimated that individuals with dissociative disorders have spent seven years in the mental health system before an accurate diagnosis. This is common because the list of symptoms that cause a person with a dissociative disorder to seek treatment is very similar to those of many other psychiatric diagnoses. Many people who have dissociative disorders also have secondary diagnoses of depression, anxiety, or panic disorders. The DSM-IV provides the following criteria to diagnose dissociative identity disorder:Two or more distinct identities or personality states are present, each with its own relatively enduring pattern of perceiving, relating to, and thinking about the environment and self.

  • At least two of these identities or personality states recurrently take control of the person’s behavior.
  • The person cannot recall important personal information that is too extensive to be explained by ordinary forgetfulness.
  • The disturbance is not due to the direct physiological effects of a substance (such as blackouts or chaotic behavior during alcohol intoxication) or a general medical condition (such as complex partial seizures).


While there’s no “cure” for dissociative identity disorder, long-term treatment is very successful, if the patient stays committed. Effective treatment includes talk therapy or psychotherapy, medications, hypnotherapy, and adjunctive therapies such as art or movement therapy. Because oftentimes the symptoms of dissociative disorders occur with other disorders, such as anxiety and depression, the dissociative disorder may be treated using the same drugs prescribed for those disorders. A person in treatment for a dissociative disorder might benefit from antidepressants or anti-anxiety medication.
