As we have described in our previous post that the dissociative identity disorder is also known as multiple personality disorder. It is a complex and rare psychological disorder that it is present in less than 1% of people and is caused by multiple factors. In recent years, the number of cases of this disorder has been increased.

It is a disorder in which multiple personalities exist in one individual with distinct memories, behavior and social relationships. Almost all of us have experienced mild dissociation for example when we lost in thought and lose the thread of the conversation of when we say lost in the moment.

Even deep dreams are a form of dissociation in which we are awakened and can’t differentiate which version of reality is true. People, who are going through a severe trauma sometimes, depend on their minds to step away from reality, just for a moment, in order to withstand the events that are occurring.

But the frequent leaves of absence similar can be a dissociative disorder. It is one of the most talked about the disorder and has generated debate and criticism. In this article, we will explore that multiple personality disorder is hereditary or not?

What Is Multiple Personality Disorder And What Are The Symptoms?

It is a mental process in which affected person’s mind lost connection or lack connection in his memories, thoughts, actions, feelings and sense of identity. The individual dissociates himself exactly from a scenario or the experience that is too violent, painful or traumatic to equate with his conscious self.

Amnesia is also experienced when an alter takes control over the person’s behavior. In some cases, it has bad consequences in personal and professional relationships. For example, an affected person may meet people who seem to know her, but she is not able to recognize or remember them.

Is Multiple Personality Disorder Hereditary

This disorder can include many psychological symptoms that can be found in other mental disorders, such as:

  • Headaches or pains in other parts of the body.
  • Disconnection of one’s thoughts, feelings, and even the body.
  • The environment becomes unfamiliar or unreal.
  • Depression.
  • Mood swings.
  • Anxiety.
  • Alterations in food and sleep.
  • Problems in sexual functioning.
  • Substance abuse.
  • Amnesia.
  • Hallucinations.
  • Suicide attempts.

Affected people also describe hearing voices of spiritual powers and sometimes these voices accompany connected series of thought that they have no control over. They might also experience a sudden, strong emotion that they can’t control. Also, they feel a sudden change in their body that can be like a small kid, muscular or giant.

They also report about dissociative fugues where they find that they have traveled but that can’t recall this experience. The most dangerous symptom among them is suicidal attacks. Most of the time, they try to suicide or injure themselves.

Multiple Personality Disorder Is Hereditary Or Not?

Although, this disorder can occur recurrently, yet no genetic factors are found in this disorder. Contradictory results are also found in genetic studies. Monozygotic and dizygotic twins were considered under a study. Monozygotic twins are developed from one zygote that is then split into two zygotes and dizygotic twins are developed due to two different zygotes.

After the study of these two twins conclude that heredity does not seem to have any effect on this disorder. On the other hand, a study insinuates the presence of a certain genetic effect that is born in mind. Also, this research emphasizes on dissociation without differentiating between pathological and non-pathological.

Therefore, many experts have a contradictory opinion on this topic. However, the data shows that multiple personality disorder is not hereditary. If an adult is going through multiple personality disorder, his children are not likely to have this disorder as other children.


Traumatic events or sexual abuse most often in childhood are the main reasons known to us. It can be due to extreme neglect and emotional abuse. It is also said that the state of this disorder is a coping mechanism that the body of the person itself creates to withstand all the fears that he has been facing through unpleasant events for a long period.

Frightening and unpredictable parents also play a role in DID. It is also said that the state of this disorder is a coping mechanism that the body of the person itself creates to withstand all the fears that he has been facing through unpleasant events for a long period.  Given below are the four factors that lead to this disorder.

  • The affected person has an intrinsic potential to segregate hence can be easily hypnotized.
  • Harrowing experiences in early childhood can disturb personality development which leads to the greater eligibility for multiple mental or emotional areas.
  • Continuously, experiencing these painful events increase the chance to not recovering this emotional or social deprivation spontaneously.
  • Social influences, mental and emotional factors shape the final presentation.

The treatment of dissociative identity disorder is the biggest challenge and we can’t say that the person is cured. The definition of the word cures varies according to the individual to individual. Some people with DID look for ways to manage their distinct personalities in a healthy way.

They are reluctant to reconnect all their distinguished identities because they help the person to withstand the morbid memories. And for others, integrating all personalities into one healthy identity is the objective. Each of these states can be achieved with DID treatment but it can be a painstaking process.

Sometimes, medication is also used in the treatment although, no medication is specifically indicated for DID. It helps people who experience certain symptoms like severe depression or anxiety. Clinical hypnosis is also used which involves intense relaxation, concentration and focused attention to achieve an altered state of consciousness.
