In dissociative disorders, such as Dissociative Identity Disorder (DID), communication and memory between different alters (also known as dissociative identities or parts) can vary widely among individuals. Remembering what other alters did or experienced is a characteristic feature of DID, but it can be complex and vary from person to person. Here are some general patterns that may occur:
Limited Awareness: The "host" is the term used to refer to the identity that is most often present and may be unaware or have limited awareness of the existence of other alters. The host may have gaps in memory regarding what other alters do when they take control. The host might not be aware of these gaps or may have a fragmented understanding of their experiences.
Alters' Awareness of Host: Some alters may be aware of what the host experiences, especially if they co-front or coexist in some form. Co-fronting refers to two or more alters sharing consciousness and awareness simultaneously. In such cases, there might be more continuity in memory between alters.
Amnesia between Alters: In many cases, alters have their own memories and experiences, and they may not have full access to each other's memories. When one alter is in control, they may not remember what other alters did while they were in the front (the state of being in control of the body).
Internal Communication and Cooperation: In some instances, alters can communicate internally in various ways, such as through thoughts, feelings, or internal dialogue. This communication might be more apparent in co-conscious states, allowing some degree of shared awareness and memory.
System Collaboration: In some DID systems (the collection of alters within an individual), the alters work together collaboratively, share information, or keep journals to help improve communication and memory gaps.
It's essential to understand that DID is a complex and unique disorder, and experiences can differ significantly from one individual to another. The way memory and communication work within a DID system can depend on factors such as the severity of dissociative barriers, the level of co-consciousness, the individual's history of trauma, and the therapeutic work they have undergone.
Therapy, particularly specialized treatment like Dialectical Behavior Therapy (DBT) or Eye Movement Desensitization and Reprocessing (EMDR), can help individuals with DID manage their symptoms, improve communication between alters, and work towards integration and cohesion within the system. Integrated therapy and support from a qualified mental health professional are essential for individuals living with dissociative disorders.
