What's the cause?

Many people with a dissociative disorder will have experienced a traumatic event in the past.

Often, this traumatic event will have been physical, sexual or emotional abuse suffered during childhood, although some people 'dissociate' after experiencing war, kidnapping or even an invasive medical procedure.

Switching off from reality is a normal defence mechanism that helps the person to cope during a traumatic time it's a form of denial, as if "this isn't happening to me".

It becomes dysfunctional when the environment is no longer traumatic but the person still acts and lives as if it is, and hasn't dealt with or processed the event.

So, a dissociative disorder is the result of the brain adapting to a difficult early life environment.It is not:

  • to do with genes
  • the result of another medical condition
  • the result of ahead injury
  • the result of drug or alcohol abuse (although many people with dissociative disorders misuse alcohol or drugs to cope)
