Imagine schizophrenia and autism being opposites on an schizophrenia-autism spectrum. To the left schizophrenia, normal in the middle and autism to the right. Let's check schizophrenia first. [Scientists Discover Gene That Predisposes Ashkenazi Jews to Schizophrenia](https://archive.is/YDCEr) [In Western Europe it has been documented that immigrant groups are more likely to be diagnosed with schizophrenia. The immigrant groups that are predominate in the increased schizophrenia diagnosis are of black origin.[19] The highest rates of schizophrenia diagnosis come from those of Afro-Caribbean ethnicity and those with black African descent.[19] In the US, African Americans have been found to be three times more likely to be diagnosed with schizophrenia](https://en.m.wikipedia.org/wiki/Epidemiology_of_schizophrenia) It seems jews, niggers and the rest are more prone to schizophrenia than Aryans. Interesting. Let's check autism. [**An increase in neuronal numbers in prefrontal cortex has recently been observed, indicating that excess neurogenesis may be the underlying cause for an increase in cerebral size in ASD** (Courchesne et al., 2011).](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5701944/) Bigger brains. More neurons especially in the *prefrontal cortex*... [This brain region has been implicated in executive functions, such as planning, decision making, working memory, personality expression, moderating social behavior and controlling certain aspects of speech and language.[5][6][7][8] Executive function relates to abilities to differentiate among conflicting thoughts, determine good and bad, better and best, same and different, future consequences of current activities, working toward a defined goal, prediction of outcomes, expectation based on actions, and social "control"](https://en.m.wikipedia.org/wiki/Prefrontal_cortex) Very promising so far, though: [We found increased risks of being diagnosed with AD overall and specifically with comorbid mental retardation in children of foreign-born mothers who were black, Central/South American, Filipino, and Vietnamese, as well as among US-born Hispanic and African American/black mothers, compared with US-born whites.](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4067639/) so might not be true
