Conversion and Dissociative Disorder


Conversion disorder, also known as functional neurological symptom disorder, is a mental condition in which an individual experiences neurological or physical symptoms that cannot be explained by neurological or medical conditions. There is usually an underlying psychological cause to the physical symptoms. These symptoms often cause impairment in social, occupational, or other important areas of functioning in one’s life.


Dissociative disorders are conditions that involve involuntary escape from reality and are often associated with disruptions/ breakdowns of memory, awareness, identity, or perception.


There are different types of dissociative disorders, including:

  • Dissociative identity disorder – Disruption of identity, resulting in two or more distinct personality states.
  • Dissociative amnesia – An inability to recall important autobiographical information, usually of a traumatic nature
  • Depersonalisation/ Derealisation disorder – Experiences of unreality, detachment, with respect to one’s thoughts, feelings, sensations, bodys, or actions (depersonalisation) or surroundings (derealisation).
