Dissociative Identity Disorder (DID), formerly known as Multiple Personality Disorder, is a complex and rare mental health condition characterized by the presence of two or more distinct identity states that control an individual's behavior, consciousness, and memory at different times. The amnesic barriers you mentioned refer to the gaps in memory between these distinct identity states. The exact age at which these barriers begin to form and leak can vary widely among individuals with DID.
DID typically develops as a response to severe and ongoing trauma during childhood, particularly in situations where a child's coping mechanisms are overwhelmed. To protect the individual from the overwhelming trauma, the mind creates distinct identity states or alters, and these states may have limited awareness of each other.
The amnesic barriers form to prevent the different identity states from being aware of each other's memories, thoughts, and experiences. This separation of memories between alters allows the individual to function and survive despite the traumatic experiences they endured.
The process of forming amnesic barriers can begin early in childhood, often before the age of 7, when the brain is still developing and highly plastic. It is during this developmental period that children are particularly vulnerable to the effects of trauma on their psychological and emotional well-being.
As for when these barriers start to leak, it can happen at any age when the individual begins to experience symptoms of DID. The barriers may start to weaken or become more permeable due to factors like increased stress, trauma triggers, or during therapy when the person starts to explore and work through their traumatic experiences.
It's important to note that the diagnosis and treatment of DID should be conducted by qualified mental health professionals with experience in dissociative disorders. The condition can be complex, and misdiagnosis is a concern, as some other mental health conditions may share similar symptoms. Early intervention and appropriate treatment can be essential for individuals living with DID to manage symptoms, cope with trauma, and improve their quality of life.
