In the context of Dissociative Identity Disorder (DID), an "alter" refers to an alternate identity or personality state that exists within the same individual. These alters can have distinct characteristics, behaviors, thoughts, emotions, memories, and even physical traits. They are often formed as a result of coping with trauma or other significant stressors during childhood.
The concept of alters is central to understanding DID. The host is the term used to describe the primary identity or personality that identifies as the individual's core self. Alters, also known as dissociative parts or personalities, may take over the person's consciousness at different times, leading to periods of amnesia or memory gaps for the host during those times.
Regarding communication between alters, yes, it is possible for alters to communicate with each other without the host knowing. This phenomenon is known as "co-consciousness" or "internal communication." When alters are co-conscious, they are aware of each other's existence and can communicate internally within the mind.
In cases where alters can communicate internally, they may have conversations, share memories, or collaborate on tasks. The level of communication and cooperation between alters can vary widely among individuals with DID. Some systems may have very limited internal communication, while others may experience more co-consciousness.
During periods of co-consciousness, the host may not be aware of what is happening internally. They might experience missing time or feel disconnected from their actions and behavior during those times when other alters are in control.
It's important to recognize that DID is a complex and often misunderstood condition. People with DID have unique experiences, and the way the disorder manifests can differ significantly from one individual to another. Treatment for DID usually involves therapy approaches that focus on improving communication and cooperation between alters and integrating their experiences to promote healing and functional unity.
