Just FYI for those who may not know ...
Dissociation and disassociation are two things that mean similar things but one is specific to psychological medicine and the other is a more general term for disconnecting from anything. A lot of people interchange these but you shouldn't.
There are 4 stages of dissociation. Each exists to help someone regulate their response to situations or tolerate/adapt to difficult stimulus. Psychological dissociation is a triggered response not a conscious one.
Usually, dissociation is combined with other psychological diagnoses. I work with many of these individuals. It is tasking to say the least as I, a layman, have to google ways to work with them. lol
Yes it can be trauma based. I do have access to previous possible trauma.
