For your consideration: the theory of "Positive Disintegration" developed by Kasimir Dabrowski does help to explain the capacity and reality of schizotypal disorders. The easiest way to explain it, is that human brain potential for "over-excitation" leads to personality development; this is natural and human. The stages of personality development are not guaranteed to succeed and proceed correctly. Most cases of schizophrenia may be a result of failed re-organization, or a failure to develop the final, executive, function. In cases of "arrested development," this process may be delayed till later in life. This is the so-called mid-life-crisis, which also can fail, and then you get adult onset schizophrenia. This is all emerging research thats usually locked up in foreign language journals. Almost no medicine to be sold here, AMA and APA are not interested...
