In Dissociative Identity Disorder (DID), the host refers to the identity that is most often present and carries the individual's given name. The host identity is not necessarily a separate alter but is more like the core identity that is responsible for day-to-day functioning and typically has the most awareness of the other alters or identities within the person with DID.
In DID, alters (also known as dissociative identities) can have various roles and functions. One common role that alters may take on is that of a "protector." Protectors are alters who have developed to cope with and manage traumatic experiences or to shield the individual from overwhelming emotions or memories. These protectors might have roles such as maintaining control, handling specific situations, or keeping certain memories or emotions hidden from the host and others.
It is possible for the host identity to also be a protector in some cases. For example, the host might take on the role of managing daily life, interactions with others, and the external responsibilities while also protecting the other alters from situations or memories that could be distressing.
DID is a complex and individualized disorder, and the specific roles and relationships between alters can vary widely from person to person. Some hosts may be more aware and cooperative with the other alters, while others may have more limited awareness or amnesia barriers between identities.
It's important to remember that DID is a result of severe trauma and is a coping mechanism to survive overwhelming experiences. Treatment involves working with a specialized mental health professional who has experience in dissociative disorders to help the individual integrate their identities, develop coping strategies, and heal from the underlying trauma. If you or someone you know is struggling with DID, seeking professional help is essential for proper assessment and treatment.
