Schizophrenia has a genetic component.
Persons with OCD and first parents having OCD have higher higher probability to develop schizophrenia. Reference:a (https://consumer.healthday.com/health-technology-information-18/genetics-news-334/people-with-ocd-may-have-higher-odds-for-schizophrenia-study-691343.html probability to develop schizophrenia).
So, it seems that a overlap can be possible overlap exists between schizophrenia and OCD. And I found this paper which dealsthis paper dealing with the genetic aspect of the relation(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3738863/).
It'sSo it seems like there can be a possible overlap bur notrelation between schizophrenia and OCD, but I cannot find enough research to support it.
So, my question is: is there enough evidence thata definitive genetic correlation between schizophrenia and OCD are related?
