Other Specified Dissociative Disorder Type 1b () is a complex dissociative condition often described as "DID without the amnesia". While not an official DSM-5 diagnosis (it is a clinical subtype of OSDD-1 ), it describes systems with distinct alters or identity states who do not experience the "blackout" amnesia typical of Dissociative Identity Disorder.

| Condition | Overlap with OSDD-1b | Key Difference | | :--- | :--- | :--- | | | Distinct alters, switching, internal communication. | Amnesia is required. If you have blackouts (missing hours/days), you likely have DID, not OSDD-1b. | | Borderline Personality Disorder (BPD) | Unstable identity, feeling "like different people" depending on mood, chronic emptiness, dissociative stress responses. | BPD lacks distinct named alters with consistent traits. The "self states" in BPD shift with emotional triggers but do not have autonomous agency. | | C-PTSD (Complex PTSD) | Dissociative flashbacks, depersonalization, sense of a "fragmented self" due to chronic trauma. | No distinct alters. The fragmentation is metaphorical (confused values), not structural (separate consciousness). | | Schizophrenia | Hearing voices, feeling controlled by outside forces, thought insertion. | Voices in schizophrenia are typically ego-dystonic (felt as alien/outside). In OSDD-1b, voices are experienced as "other parts of me" inside the head. No delusions in OSDD. | | ADHD + Maladaptive Daydreaming | Distraction, internal chatter, feeling "zoned out," elaborate inner worlds. | No loss of agency. The person knows they are inventing the characters. In OSDD-1b, alters act unpredictably and feel autonomous. | OSDD-1b Other Specified Dissociative Disorder Type 1b ()
