In Dissociative Identity Disorder (DID), formerly known as multiple personality disorder, the concept of a "host" refers to the identity that is most commonly present and carries the person's given name. "Alters" or "alternate identities" are the distinct identities or personality states within the individual with DID.
In some cases, the "host" identity may go dormant for extended periods, which means they are not active or present in the person's daily life. During this dormancy, the other alters may be more active and in control of the person's thoughts, emotions, and behaviors. When the host identity is dormant, it might seem as if that part of the person is not aging, as they are not actively experiencing or participating in life events.
In some situations, when the host identity re-emerges after being dormant, they may experience a regressed state or age regression. Age regression is a phenomenon in which an alter takes on the characteristics and behaviors of a younger age, which can include speech patterns, mannerisms, and emotional responses. This may result in the alter presenting as "little" or younger than their chronological age.
It's essential to understand that DID is a complex and nuanced disorder, and the experiences of individuals with DID can vary significantly. The interactions and relationships between different alters can be intricate and unique to each person's situation.
If you or someone you know is dealing with DID or related concerns, it's crucial to seek professional help from a qualified mental health professional with experience in dissociative disorders. They can provide appropriate support, understanding, and therapeutic interventions to address the challenges associated with DID.
