Dissociation is a mental process that causes a lack of connection in a person’s thoughts, memory and sense of identity. Dissociation seems to fall on a continuum of severity. Mild dissociation would be like daydreaming, getting “lost” in a book, or when you are driving down a familiar stretch of road and realize that you do not remember the last several miles. A severe and more chronic form of dissociation is seen in the disorder Dissociative Identity Disorder.
The goals of treatment for Dissociative disorders are to relieve symptoms, to ensure the safety of the individual, and to "reconnect" the different identities into one well-functioning identity. The best treatment approach depends on the individual and the severity of his or her symptoms. Treatment is likely to include combination of some methods like Psychotherapy, Cognitive therapy, Medication, Family therapy, Creative therapies and clinical hypothesis
Research trends currently focus on neurobiological and psychobiological factors unique to this disorder. For example, one study investigated the differences between alters who have access to traumatic memories and alters who suppress such information. The results indicate that different alters demonstrate differences in emotional, sensori-motor, cardiovascular, and regional cerebral blood flow in response to traumatic memories.
