An interesting finding: Schizophrenics respond well to oxytocin when it's administered with other anti-psychotics in the right doses.
The studies I read a few years ago showed that oxytocin had no effect on pwAsPD. The hypothesis at that time was that smthg was glitchy in the participants' uptake process. Likely smthg with the receptors and not the neurochemistry balance. However, research at that time was brand new and testing was limited.
There may be more current studies on pwAsPD and oxytocin available now.
