>researchers continued to puzzle over if the increased acidity seen in schizophrenia and bipolar patients was truly disorder-related—or the result of other factors, such as a person’s history of antipsychotic drug use Excuse my ignorance, but I don't see how they ruled out the possible link between antipsychotic drug use and increased acidity? I'm also puzzled by how they can confidently diagnose rodents with human social disorders based solely on "genetic indicators" when the links between genetics and disorders like schizophrenia are still far from understood.
