Split personality disorder : what is DID Its Causes & Treatment

Dual personality disorder

Dual personality disorder, also known as Dissociative Identity Disorder (DID), is a complex and often misunderstood mental illness characterized by the presence of two or more distinct personalities or identities within one individual. The condition is rare, affecting only 0.1% of the general population, and is often the result of severe and prolonged trauma during childhood.

Individuals with DID may experience a range of symptoms, including memory lapses, unexplained changes in behaviour, and gaps in personal history. They may also experience significant distress and impairment in their daily lives as a result of their condition. In this essay, we will explore the causes, symptoms, and treatments of DID and consider the controversies surrounding this condition.

Causes of DID

The exact causes of DID are not fully understood, but experts believe that the disorder is the result of severe and prolonged trauma during childhood. Trauma can take many forms, including physical, sexual, and emotional abuse, neglect, and witnessing or experiencing violence. The trauma is believed to cause the development of multiple personalities as a coping mechanism, allowing the individual to dissociate from the traumatic experience and create a new identity to protect themselves from further harm.

Additionally, individuals with DID may have a genetic predisposition to the disorder, as well as brain abnormalities that contribute to the development of the condition. However, these factors alone are not believed to cause DID, and trauma is still considered the primary cause of the disorder.

Symptoms of DID

The most prominent symptom of DID is the presence of two or more distinct identities or personalities within one individual. These identities may have their own names, characteristics, and behaviour patterns, and may vary in age, gender, or cultural background. Individuals with DID may experience gaps in their memory as a result of the switching between identities, and may be unable to recall certain events or personal information.

Other symptoms of DID may include depression, anxiety, sleep disorders, and dissociative symptoms such as feeling detached from oneself or the world around them. Individuals with DID may also experience self-harm, suicidal thoughts, or substance abuse as a way to cope with their condition.

Diagnosis of DID

Diagnosis of DID can be challenging, as the symptoms of the disorder can be similar to those of other mental health conditions. A thorough evaluation by a mental health professional is necessary to determine whether an individual has DID.

The diagnostic criteria for DID according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) include:

  • Presence of two or more distinct identities or personality states.
  • At least two of these identities or personality states recurrently take control of the person’s behaviour.
  • Inability to recall important personal information that is too extensive to be explained by ordinary forgetfulness.
  • Symptoms cause significant distress or impairment in social, occupational, or other areas of functioning.
  • Symptoms are not due to a substance or medical condition.

Treatment of DID

The treatment of DID typically involves psychotherapy, which aims to help individuals with the disorder integrate their multiple identities into one cohesive sense of self. This may involve techniques such as talk therapy, cognitive-behavioural therapy, or eye movement desensitization and reprocessing (EMDR) therapy.

Medications may also be prescribed to treat comorbid conditions such as depression or anxiety, but there are no medications specifically designed to treat DID itself.

Controversies surrounding DID

DID remains a controversial condition in the field of mental health, with some experts questioning its validity as a distinct disorder. Some critics argue that the symptoms of DID may be the result of suggestion or manipulation by therapists or may be the result of cultural or social factors.

Additionally, some critics argue that the diagnosis of DID may be overused or misdiagnosed, leading to unnecessary treatment and stigma for those who do.
