OSDD-1b (Otherwise Specified Dissociative Disorder - Type 1b) is a subtype of dissociative disorder where there is significant dissociative amnesia between alters (different identities or personality states). Alters may have difficulty recalling important personal information, events, or experiences that happened to other alters.
Blurred or fragmented memories between alters are common in dissociative disorders like OSDD-1b. This can result in what might be perceived as "amnesia" between alters, as there is a lack of cohesive memory continuity among them.
If you suspect that you are experiencing OSDD-1b or any other mental health condition, it is essential to seek a proper diagnosis and support from a qualified mental health professional. They can help you understand your experiences better and provide appropriate guidance and treatment. Remember that only a mental health expert can diagnose and address your specific situation accurately.
