✧ What is Dissociative Identity Disorder?: Part 5 ✧
As we've learned over the last 2 weeks, DID is a constellation of unique and downright impressive qualities. While bred out of trauma and sheer survival, the brilliance exercised by both mind and body deserves our attention.
Survivors with DID may share some baseline diagnostic criteria, but from there on, nothing else is the same! Nothing. A person's system could have 2, 20, or 200+ alters. Each self-state (aka alter, part, or insider) could be completely different and know in explicit detail what each one looks, sounds, writes, and acts like. Or, they may be more fragmented, one-dimensional, or less fully-realized than the others. (This is particularly common in very large, 'polyfragmented' systems - seen most often in organized abuse survivors.)
Different survivors may view their systems as though they were a parent to many kids inside; as a collection of best friends, siblings, or roommates; or more like a huge dysfunctional family, a classroom, tribe, or some other collective dynamic. They may have an elaborate internal world – a place within the mind where alters live, interact, and roam; one that may be comprised of a home, a city, separate beaches, a castle, pods or bedrooms, or some larger picturesque landscapes. For others, the visual space is very simple - just a meeting room, roundtable, or seating area. Some may have no internal world at all! These folks may try creating one as an adult and find it really helpful or discover it's not really for them or very beneficial. Others may try but simply be unsuccessful. (Aphantasia may be at play here, too.)
Alters can be any shape, size, gender, orientation, faith, origin, or even be non-human. Most parts formulate an identity through the imagination of a child, albeit unconsciously, with the limited information they have about the world at the time and from their additionally limited corner of the mind no less. Things get creative!
Most commonly, these traits exist to meet a need of that traumatized little one. Some common examples include: a nurturing mother figure, a strong older brother to physically protect them, someone who cannot speak or see at all (and thus can't risk revealing any 'secrets' or see the scary things happening to them), parts who "aren't real" so they can't be hurt, someone who is intimidating or at times even threatening, or someone who can only categorically store trauma/emotions as data (like a computer) to keep it both organized and unfelt emotionally. Or, if their traumatized mind found protection/comfort in wolves, being an alter with no physical body, or being of a different gender, age, or nationality to themselves — then so it shall be!
Unfortunately, sometimes this also means incorporating some stereotypical, inaccurate, or even discriminatory ideas about groups of people - fed to them by toxic adults or their general environment. Thankfully, these projected traits can be undone/shifted into healthier identifications later in life, through therapy or independently, after new information is gained. It's important to remember that these kids didn't have a choice then, it's an unconscious process, and they didn't know the judgments held by those around them were so dangerous or damaging. They were just trying to survive or assimilate. But now, as adults, with time and work, this can change internally and honor everyone - inside and out!
That said, not every alter has a "reason" for being as they are. Some just...are! And that's just as okay! Names can work the same. Some developed them organically, others chose their own, while others have no name at all! They may keep it that way or decide to try one on later!
Naturally, due to the inherent needs of most traumatized children - as well as a system's need to run smoothly - themes can emerge between the TYPES of alters many otherwise very, very different survivors can have (e.g. "protectors", "littles"/kid parts, "introjects", "gatekeepers", "healers", etc). But, not every alter has a clearly outlined job/title or can explain what role they exist to serve. Suggesting they SHOULD have one can be harmful messaging. Some systems don't have a SINGLE commonly-observed alter type that we often see represented in media or educational materials on DID/OSDD. Others will have them all! No system NEEDS to have, or go find, any specific type of alter in order to be functional, valid, or diagnosed. Themes; never absolutes!
One of the most unique aspects of DID, by far, is how alters can possess different talents, knowledge, or skill sets; speak with different accents, speech patterns, or in languages no one else does; or even elicit different brain waves, vital signs, allergies, medical health conditions, vision, and more. Yes, this is very real and even makes neurobiological sense! Traumatized brains not only result in the restructuring of one's psychology, but rewire the actual brain-to-body neural circuitry, too.
The brain controls everything our organs do and how the body interprets that data. If a different alter is forward, they're utilizing different pathways of the brain. That circuitry then dictates a very different set of instructions to the body - which may then result in blood sugar variation, the brain reading visual input from the eyes differently, metabolizing food and medications at faster/slower rates, or showing variations in heart rate, hormone/histamine production, sensory processing, handwriting, speech cadence, body temperature, posture, and more. Some of these changes have a functional purpose, to keep them well during specific traumas, while others "just are"!
DID is an incredible, adaptive condition and we can only hope to shine a healthy, positive spotlight on these survivors. One that respects their trauma, admires their creativity, and honors their resilience. We won't sugarcoat the many challenges that complex childhood trauma inflicts, but the stigma around its resulting conditions is completely ill-placed and unfounded. We're here to redirect that conversation.
