What is Depersonalization Disorder?

The depersonalization disorder is characterized by the experimentation of serious feelings of unreality that dominate the life of the person and that prevent normal functioning in life.

Depersonalization and derealization sensations may be part of a variety of disorders – such as acute stress disorder – although when they are the main problem, the person meets the criteria for this disorder.

People with this disorder may present a cognitive profile with deficits in attention, short-term memory or spatial reasoning.

They may be easily distracted and have difficulty perceiving three-dimensional objects.

Although it is not precisely known how these perceptual and cognitive deficits develop, they appear to be related to tunnel vision (perceptual distortions) and mental void (difficulties in capturing new information).

Depersonalization Disorder

In addition to the symptoms of depersonalization and derealization, the inner agitation created by the disorder can lead to depression, self-harm, low self-esteem, anxiety attacks, panic attacks ,  phobias …

Although the disorder is an alteration in the subjective experience of reality, it is not a form of  psychosis , since people who suffer it retain the ability to distinguish between their own internal experiences and the external objective reality.

The chronic form of this disorder has a prevalence of 0.1 to 1.9%.

While derealization or depersonalization episodes may occur in the general population, the disorder is diagnosed only when the symptoms cause significant discomfort or problems in the workplace, family or social.

Depersonalization Disorder Symptoms

Persistent episodes of depersonalization and derealization can cause discomfort and malfunction at work, at school, or in other areas of life.

During these episodes, the person is aware that their sense of detachment are only sensations, not a reality.

Symptoms of depersonalization

  • Sensations of being an external observer of thoughts, feelings or feeling of being floating.
  • Sensations of being a robot or not being in control of speech or other movements.
  • Feeling that the body, legs or arms are distorted or elongated.
  • Emotional or physical numbness of the senses or responses to the external world.
  • Sensations that memories lack emotions, and that they may not be the memories themselves.

Symptoms of derealization

  • Sensations of unfamiliarity with the external environment, such as being in a movie.
  • Feeling emotionally disconnected from people nearby.
  • The external environment seems distorted, artificial, colorless or unclear.
  • Distortions in the perception of time, as recent events sensed as the distant past.
  • Distortions about the distance, size and shape of objects.
  • Episodes of depersonalization or derealization can last for hours, days, weeks, or even months.

In some people, these episodes become permanent emotions of depersonalization or derealization that may improve or worsen.

In this disorder, the sensations are not caused directly by drugs, alcohol, mental disorders or other medical condition.

Diagnosis

Diagnostic criteria according to DSM-IV

  1. A) Persistent or recurrent experiences of detachment or of being an external observer of one’s own mental processes or body (for example, feeling as if one were in a dream).
  2. B) During the episode of depersonalization, the sense of reality remains intact.
  3. C) Depersonalization causes clinically significant discomfort or social, occupational, or other important life-related impairment.
  4. D) The episode of depersonalization appears explicitly in the course of another mental disorder, such as schizophrenia, anxiety disorders, acute stress or other dissociative disorders, and is not due to the direct physiological effects of a substance , Drugs or drugs) or to a medical condition (eg, temporal lobe epilepsy ).

ICE-10


In ICE-10, this disorder is called depersonalization-derealization disorder. The diagnostic criterion is:

  1. One of the following:
  • Symptoms of depersonalization. For example, the individual feels that their feelings or experiences are distant.
  • Derealization symptoms. For example, objects, people or the environment seem unreal, distant, artificial, colorless or lifeless.
  1. An acceptance that it is a spontaneous or subjective change, not imposed by outside forces or by other people.

The diagnosis should not be given in certain specific conditions, for example in alcohol or drug poisonings, or together with schizophrenia , mood or anxiety disorders.

Causes

The exact cause of this disorder is not known, although biopsychosocial risk factors have been identified.

The most common immediate precipitators of the disorder are:

  • Severe stress.
  • Emotional abuse in childhood is a significant predictor of diagnosis.
  • Major depressive disorder .
  • Ingestion of hallucinogens.
  • Death of a close person.
  • Severe trauma, like a car accident.

Not much is known about the neurobiology of this disorder, although there is evidence that the prefrontal cortex could inhibit neural circuits that normally form the emotional substrate of the experience.

This disorder may be associated with dysregulation of the hypothalamic-pituitary-adrenal axis, the area of ​​the brain involved in the “fight or flight” response. Patients demonstrate abnormal levels of cortisol and basal activity.

Cannabis

In some cases, the use of cannabis may lead to dissociative states such as depersonalization and derealization.


Sometimes these effects can remain persistent and result in this disorder.

When cannabis is consumed in high doses during adolescence, it increases the risk of developing this disorder, especially in cases in which the person is predisposed to psychosis.

Cannabis-induced depersonalization disorder usually occurs in adolescence and is more common in boys and in ages between 15 and 19 years.

Treatment

Depersonalization disorder lacks effective treatment, in part because the psychiatric community has focused on research on other diseases, such as alcoholism.

A variety of psychotherapeutic techniques, such as cognitive-behavioral therapy, are currently used.

In addition, the effectiveness of drugs such as selective serotonin reuptake inhibitors (SSRIs), antivonvulsants, or opioid antagonists are being investigated .

Cognitive-behavioral therapy

It is intended to help patients reinterpret the symptoms in a non-threatening way.

Medication

It has been found that antidepressants, benzodiazepines, and antipsychotics are not useful.

There is some evidence supporting naloxone and naltrexone .

A combination of SSRIs and a benzodiazepine has been proposed to treat people with this disorder and anxiety.

In a 2011 study with lamotrigine it was found to have efficacy when treating depersonalization disorder.

Modafinil has been effective in a subgroup of people with depersonalization, attention problems and hypersomnia .
