Can early childhood sexual abusive lead to schizoaffective disorder bipolar type? with no family history of schizophrenia?

PTSD: Ptsd sometimes include features that are prima facie undistinguishable from sad criteria. Overlaps are possible, however sporadic (non familial) sad cases exist. My impression is that ptsd shoud be ruled in or out as the main first step, and treated appropriately if found. Addictive agents should be avoided, other medical conditions explored (osa, thyroid issues, anemia?) and controlled. Best, .

Trauma: Schizo affective disorder or likely genetically predisposed to the condition. The genetics may be inherited or by spontaneous mutation. In a genetically volnurable individual a stress such as trauma can lead to the manifestation of the condition.

Can happen..: If it has been so severe and chronic that a usual sequence would be ptsd first, then psychotic features from initial flashback. Eventually the personality becomes so fragile it detaches from reality. Add to this genetic vulnerabilities that are not apparent to people in the family. Many reasons abuse in families can make it difficult to get all the data. Environment and genes are key.
