In this, I’ll be writing about the four main types of dissociative disorders and the required criteria to have a diagnosis. If you feel you have one of these, please talk to someone. Holding this in could be harmful to yourself, and getting needed help, if available, is always a good choice.
Dissociative Identity Disorder (DID): DID is a psychobiological response to traumas suffered in the time window of about 5 to 11 years of age; it’s a complex post-traumatic stress disorder, and a dissociative disorder, but not a personality disorder. DID was previously classified as Multiple Personality Disorder until 1994 when the DSM-4 was released. It isn’t as rare as it once was believed to be, as it affects 1-3% of the population. Most with DID, have a mixture of dissociative, post-traumatic stress, and non-trauma related symptoms. DID amnesia can occur at any time whether it be for an everyday event like taking medicine, or something big like trauma.
The criteria for a valid DID diagnosis is: a disruption of identity, classified by specifically two or more distinct personalities; a break in responsiveness to outside stimuli, behavior, memory, perception, and cognition; recurring gaps in memory (regardless of the importance of the events); and the previous symptoms causing major distress or impairment in social, occupational, or other important areas of daily function. The diagnosis can only be sound if the symptoms aren’t caused by substance abuse, another medical condition, or cultural practice.
Dissociative Amnesia: This is the most common of dissociative disorders. It is classified by amnesia not caused by physical brain trauma, but rather psychological trauma, and is usually comorbid with other mental disorders.
There are three types of dissociative amnesia. Localized is a failure to recall events during a specific period of time. Selective is remembering some, but not all events during a space of time. (i.e. only parts of a traumatic may be recalled.) Generalized is complete amnesia of one’s life and history.
The criteria for dissociative amnesia is: an inability to recall important personal information, usually of a traumatic/stressful nature inconsistent with normal forgetting; These symptoms have to cause significant distress or impairment in social, occupational, and other important areas of function; not be attributable to drug abuse or another medical condition or neurological syndrome. It must also not be better explained by DID, PTSD, acute stress disorder, or major or mild neurocognitive disorder.
Depersonalization/Derealization: these two are caused usually by emotional abuse/neglect, but also could be attributed to witnessing domestic violence, being raised by a mentally unstable parent, or the sudden loss of a relative/loved one. They can also be temporarily caused by recreational drug use, but the diagnosis is only viable if it persists after the drug has worn off.
The criteria for a depersonalization diagnosis is: unreality, detachment, and feeling like an “outsider” to one’s own thoughts, feelings, sensations, body, and/or actions. Derealization is the same, but with regards to surroundings and outside stimuli. During an occurence of depersonalization/derealization, reality testing remains unimpaired. These symptoms have to cause significant distress or impairment in social, occupational, and other important areas of function. They also must not be caused by physiological effects of a drug or another medical condition or mental illness.
Other Specified Dissociative Disorder (OSDD): condition in which there are dissociative symptoms, not meeting any other dissociative disorder’s criteria. This disorder’s symptoms apply ONLY to symptom characteristics that do not meet the full criteria. It replaced DDNOS in 2013, and is caused typically by psychological trauma.
The symptoms include: chronic and recurrent syndromes of mixed symptoms- including identity disturbance with lesser noticeable gaps in sense of self, alterations of identity, or episodes of “possession” with no amnesia; acute dissociative reactions to stress, and going into a dissociative trance. A dissociative trance is an acute narrowing or complete loss of awareness of immediate surroundings that manifests as intensive unresponsiveness or insensitivity to stimuli.
OSDD can be caused by environmental factors such as brainwashing, thought reform, indoctrination while in captivity, torture, recruitments by sects and/or cults, etc.
