Schizophrenia is basically symptoms of permeability of the blood brain barrier. Whole proteins pass through and mess things up. Similar to automimmune disease. Why else are those diseases on the list the only ones increasing in pravalence, and all others are decreasing (infectious, cancerous, viral, etc.). ASD is neuroprotective and tightens those cell junctions, with behavioral drawbacks. All these things are interrelated, the issue is they can be caused by 100k different contributing factors and susceptibilities.

increasing in prevalence? or increasing in diagnosis?

If the diagnosis rate (incidence) increases, and people aren't dying rapidly, then the prevalence would surely increase as well. Unless you're using prevalence in the context of total people affected by a disease, regardless of whether or not they were diagnosed.
